Romania officially made peace with the Central Powers by signing the Treaty of Bucharest on 7 May Under the treaty, Romania was obliged to end the war with the Central Powers and make small territorial concessions to Austria-Hungary, ceding control of some passes in the Carpathian Mountains , and to grant oil concessions to Germany. In exchange, the Central Powers recognised the sovereignty of Romania over Bessarabia.
The treaty was renounced in October by the Alexandru Marghiloman government, and Romania nominally re-entered the war on 10 November against the Central Powers. Russian plans for the start of the war called for simultaneous invasions of Austrian Galicia and East Prussia. Although Russia's initial advance into Galicia was largely successful, it was driven back from East Prussia by Hindenburg and Ludendorff at the battles of Tannenberg and the Masurian Lakes in August and September Despite Russia's success in the June Brusilov Offensive against the Austrians in eastern Galicia,  the offensive was undermined by the reluctance of other Russian generals to commit their forces to support the victory.
Allied and Russian forces were revived only briefly by Romania's entry into the war on 27 August, as Romania was rapidly defeated by a Central Powers offensive. Meanwhile, unrest grew in Russia as the Tsar remained at the front. The increasingly incompetent rule of Empress Alexandra drew protests and resulted in the murder of her favourite, Rasputin , at the end of In March , demonstrations in Petrograd culminated in the abdication of Tsar Nicholas II and the appointment of a weak Provisional Government , which shared power with the Petrograd Soviet socialists.
This arrangement led to confusion and chaos both at the front and at home. The army became increasingly ineffective. Following the Tsar's abdication, Vladimir Lenin —with the help of the German government—was ushered by train from Switzerland into Russia 16 April The Revolution of November was followed in December by an armistice and negotiations with Germany. At first, the Bolsheviks refused the German terms, but when German troops began marching across Ukraine unopposed, the new government acceded to the Treaty of Brest-Litovsk on 3 March The treaty ceded vast territories, including Finland, the Baltic provinces , parts of Poland and Ukraine to the Central Powers.
With the adoption of the Treaty of Brest-Litovsk, the Entente no longer existed. The Allied powers led a small-scale invasion of Russia, partly to stop Germany from exploiting Russian resources, and to a lesser extent, to support the "Whites" as opposed to the "Reds" in the Russian Civil War.
The Czechoslovak Legion fought on the side of the Entente. Its goal was to win support for the independence of Czechoslovakia. After this success, the number of Czechoslovak legionaries increased, as well as Czechoslovak military power. In the Battle of Bakhmach , the Legion defeated the Germans and forced them to make a truce.
In Russia, they were heavily involved in the Russian Civil War, siding with the Whites against the Bolsheviks , at times controlling most of the Trans-Siberian railway and conquering all the major cities of Siberia. The presence of the Czechoslovak Legion near Yekaterinburg appears to have been one of the motivations for the Bolshevik execution of the Tsar and his family in July Legionaries arrived less than a week afterwards and captured the city. Because Russia's European ports were not safe, the corps was evacuated by a long detour via the port of Vladivostok.
The last transport was the American ship Heffron in September On 12 December , after ten brutal months of the Battle of Verdun and a successful offensive against Romania , Germany attempted to negotiate a peace with the Allies. Soon after, the US President, Woodrow Wilson, attempted to intervene as a peacemaker, asking in a note for both sides to state their demands. Lloyd George's War Cabinet considered the German offer to be a ploy to create divisions amongst the Allies. After initial outrage and much deliberation, they took Wilson's note as a separate effort, signalling that the United States was on the verge of entering the war against Germany following the "submarine outrages".
While the Allies debated a response to Wilson's offer, the Germans chose to rebuff it in favour of "a direct exchange of views". Learning of the German response, the Allied governments were free to make clear demands in their response of 14 January.

They sought restoration of damages, the evacuation of occupied territories, reparations for France, Russia and Romania, and a recognition of the principle of nationalities. Events of proved decisive in ending the war, although their effects were not fully felt until The British naval blockade began to have a serious impact on Germany. In response, in February , the German General Staff convinced Chancellor Theobald von Bethmann-Hollweg to declare unrestricted submarine warfare, with the goal of starving Britain out of the war. German planners estimated that unrestricted submarine warfare would cost Britain a monthly shipping loss of , tons.
The General Staff acknowledged that the policy would almost certainly bring the United States into the conflict, but calculated that British shipping losses would be so high that they would be forced to sue for peace after five to six months, before American intervention could have an effect. After July, the newly re-introduced convoy system became effective in reducing the U-boat threat.
Britain was safe from starvation, while German industrial output fell, and the United States joined the war far earlier than Germany had anticipated. On 3 May , during the Nivelle Offensive, the French 2nd Colonial Division, veterans of the Battle of Verdun, refused orders, arriving drunk and without their weapons. Their officers lacked the means to punish an entire division, and harsh measures were not immediately implemented. The French Army Mutinies eventually spread to a further 54 French divisions, and 20, men deserted. However, appeals to patriotism and duty, as well as mass arrests and trials, encouraged the soldiers to return to defend their trenches, although the French soldiers refused to participate in further offensive action.
Previously, British and French armies had operated under separate commands. In December, the Central Powers signed an armistice with Russia, thus freeing large numbers of German troops for use in the west. With German reinforcements and new American troops pouring in, the outcome was to be decided on the Western Front. The Central Powers knew that they could not win a protracted war, but they held high hopes for success based on a final quick offensive. Furthermore, both sides became increasingly fearful of social unrest and revolution in Europe. Thus, both sides urgently sought a decisive victory.
In , Emperor Charles I of Austria secretly attempted separate peace negotiations with Clemenceau, through his wife's brother Sixtus in Belgium as an intermediary, without the knowledge of Germany. Italy opposed the proposals. When the negotiations failed, his attempt was revealed to Germany, resulting in a diplomatic catastrophe. In early , the front line was extended and the Jordan Valley was occupied, following the First Transjordan and the Second Transjordan attacks by British Empire forces in March and April They were replaced by Indian Army units.
During several months of reorganisation and training of the summer, a number of attacks were carried out on sections of the Ottoman front line. These pushed the front line north to more advantageous positions for the Entente in preparation for an attack and to acclimatise the newly arrived Indian Army infantry. It was not until the middle of September that the integrated force was ready for large-scale operations. The reorganised Egyptian Expeditionary Force, with an additional mounted division, broke Ottoman forces at the Battle of Megiddo in September In two days the British and Indian infantry, supported by a creeping barrage, broke the Ottoman front line and captured the headquarters of the Eighth Army Ottoman Empire at Tulkarm , the continuous trench lines at Tabsor , Arara , and the Seventh Army Ottoman Empire headquarters at Nablus.
The Desert Mounted Corps rode through the break in the front line created by the infantry. Samakh and Tiberias on the Sea of Galilee were captured on the way northwards to Damascus. The Armistice of Mudros , signed at the end of October, ended hostilities with the Ottoman Empire when fighting was continuing north of Aleppo. At the outbreak of the war, the United States pursued a policy of non-intervention , avoiding conflict while trying to broker a peace.
1. The first German serviceman killed in the war was killed by the Japanese.
Wilson unsuccessfully tried to mediate a settlement. However, he also repeatedly warned that the United States would not tolerate unrestricted submarine warfare, in violation of international law. Former president Theodore Roosevelt denounced German acts as "piracy". In January , Germany decided to resume unrestricted submarine warfare, realising it would mean American entry.
In return, the Germans would finance Mexico's war and help it recover the territories of Texas, New Mexico, and Arizona. From there it made its way to President Wilson who released the Zimmermann note to the public, and Americans saw it as casus belli. Wilson called on anti-war elements to end all wars, by winning this one and eliminating militarism from the globe. He argued that the war was so important that the US had to have a voice in the peace conference.
The United States was never formally a member of the Allies but became a self-styled "Associated Power". The United States had a small army, but, after the passage of the Selective Service Act , it drafted 2. German General Staff assumptions that it would be able to defeat the British and French forces before American troops reinforced them were proven incorrect. Several regiments of US Marines were also dispatched to France. The British and French wanted American units used to reinforce their troops already on the battle lines and not waste scarce shipping on bringing over supplies.
General John J. As an exception, he did allow African-American combat regiments to be used in French divisions. Ludendorff drew up plans codenamed Operation Michael for the offensive on the Western Front. The Spring Offensive sought to divide the British and French forces with a series of feints and advances. The German leadership hoped to end the war before significant US forces arrived. The operation commenced on 21 March with an attack on British forces near Saint-Quentin. British and French trenches were penetrated using novel infiltration tactics , also named Hutier tactics after General Oskar von Hutier , by specially trained units called stormtroopers.
Previously, attacks had been characterised by long artillery bombardments and massed assaults. In the Spring Offensive of , however, Ludendorff used artillery only briefly and infiltrated small groups of infantry at weak points. They attacked command and logistics areas and bypassed points of serious resistance.
More heavily armed infantry then destroyed these isolated positions. This German success relied greatly on the element of surprise. Many Germans thought victory was near. After heavy fighting, however, the offensive was halted. Lacking tanks or motorised artillery , the Germans were unable to consolidate their gains. The problems of re-supply were also exacerbated by increasing distances that now stretched over terrain that was shell-torn and often impassable to traffic. General Foch pressed to use the arriving American troops as individual replacements, whereas Pershing sought to field American units as an independent force.
These units were assigned to the depleted French and British Empire commands on 28 March. General Foch was appointed as supreme commander of the Allied forces. Haig, Petain, and Pershing retained tactical control of their respective armies; Foch assumed a co-ordinating rather than a directing role, and the British, French, and US commands operated largely independently.
The Allies halted the drive after limited territorial gains by Germany. The resulting counter-attack, which started the Hundred Days Offensive , marked the first successful Allied offensive of the war. By 20 July, the Germans had retreated across the Marne to their starting lines,  having achieved little, and the German Army never regained the initiative.
German casualties between March and April were ,, including many highly trained stormtroopers. Meanwhile, Germany was falling apart at home. Anti-war marches became frequent and morale in the army fell. Industrial output was half the levels. In the late spring of , three new states were formed in the South Caucasus : the First Republic of Armenia , the Azerbaijan Democratic Republic , and the Democratic Republic of Georgia , which declared their independence from the Russian Empire.
Two other minor entities were established, the Centrocaspian Dictatorship and South West Caucasian Republic the former was liquidated by Azerbaijan in the autumn of and the latter by a joint Armenian-British task force in early With the withdrawal of the Russian armies from the Caucasus front in the winter of —18, the three major republics braced for an imminent Ottoman advance, which commenced in the early months of Solidarity was briefly maintained when the Transcaucasian Federative Republic was created in the spring of , but this collapsed in May, when the Georgians asked for and received protection from Germany and the Azerbaijanis concluded a treaty with the Ottoman Empire that was more akin to a military alliance.
Armenia was left to fend for itself and struggled for five months against the threat of a full-fledged occupation by the Ottoman Turks before defeating them at the Battle of Sardarabad. The defenders displayed a marked collapse in morale, causing Ludendorff to refer to this day as the "Black Day of the German army". Rather than continuing the Amiens battle past the point of initial success, as had been done so many times in the past, the Allies shifted attention elsewhere.
Allied leaders had now realised that to continue an attack after resistance had hardened was a waste of lives, and it was better to turn a line than to try to roll over it. They began to undertake attacks in quick order to take advantage of successful advances on the flanks, then broke them off when each attack lost its initial impetus.
The day after the Offensive began, Ludendorff said: "We cannot win the war any more, but we must not lose it either. We have nearly reached the limit of our powers of resistance. The war must be ended. Austria and Hungary warned that they could only continue the war until December, and Ludendorff recommended immediate peace negotiations.
Prince Rupprecht warned Prince Max of Baden: "Our military situation has deteriorated so rapidly that I no longer believe we can hold out over the winter; it is even possible that a catastrophe will come earlier. British and Dominion forces launched the next phase of the campaign with the Battle of Albert on 21 August. From German accounts, "Each day was spent in bloody fighting against an ever and again on-storming enemy, and nights passed without sleep in retirements to new lines.
27 Interesting Facts About World War I
Faced with these advances, on 2 September the German Supreme Army Command issued orders to withdraw in the south to the Hindenburg Line. This ceded without a fight the salient seized the previous April. The German High Command realised that the war was lost and made attempts to reach a satisfactory end.
On 14 September Austria sent a note to all belligerents and neutrals suggesting a meeting for peace talks on neutral soil, and on 15 September Germany made a peace offer to Belgium. Both peace offers were rejected. In September the Allies advanced to the Hindenburg Line in the north and centre. The Germans had now retreated to positions along or behind the Hindenburg Line.
That same day, Supreme Army Command informed the leaders in Berlin that armistice talks were inevitable. The following week, co-operating French and American units broke through in Champagne at the Battle of Blanc Mont Ridge , forcing the Germans off the commanding heights, and closing towards the Belgian frontier. When Bulgaria signed a separate armistice on 29 September, Ludendorff, having been under great stress for months, suffered something similar to a breakdown. It was evident that Germany could no longer mount a successful defence. The collapse of the Balkans meant that Germany was about to lose its main supplies of oil and food.
Its reserves had been used up, even as US troops kept arriving at the rate of 10, per day. News of Germany's impending military defeat spread throughout the German armed forces. The threat of mutiny was rife. Admiral Reinhard Scheer and Ludendorff decided to launch a last attempt to restore the "valour" of the German Navy. In northern Germany, the German Revolution of — began at the end of October Units of the German Navy refused to set sail for a last, large-scale operation in a war they believed to be as good as lost, initiating the uprising.
The sailors' revolt , which then ensued in the naval ports of Wilhelmshaven and Kiel , spread across the whole country within days and led to the proclamation of a republic on 9 November , shortly thereafter to the abdication of Kaiser Wilhelm II, and to German surrender. With the military faltering and with widespread loss of confidence in the Kaiser leading to his abdication and fleeing of the country, Germany moved towards surrender. Prince Maximilian of Baden took charge of a new government on 3 October as Chancellor of Germany to negotiate with the Allies.
Negotiations with President Wilson began immediately, in the hope that he would offer better terms than the British and French. Wilson demanded a constitutional monarchy and parliamentary control over the German military. The Kaiser, kings and other hereditary rulers all were removed from power and Wilhelm fled to exile in the Netherlands.
Imperial Germany was dead; a new Germany had been born as the Weimar Republic. The collapse of the Central Powers came swiftly. Bulgaria was the first to sign an armistice, the Armistice of Salonica on 29 September On 24 October, the Italians began a push that rapidly recovered territory lost after the Battle of Caporetto. This culminated in the Battle of Vittorio Veneto, which marked the end of the Austro-Hungarian Army as an effective fighting force. The offensive also triggered the disintegration of the Austro-Hungarian Empire.
During the last week of October, declarations of independence were made in Budapest, Prague, and Zagreb. On 29 October, the imperial authorities asked Italy for an armistice, but the Italians continued advancing, reaching Trento, Udine, and Trieste.
The terms, arranged by telegraph with the Allied Authorities in Paris, were communicated to the Austrian commander and accepted. Austria and Hungary signed separate armistices following the overthrow of the Habsburg Monarchy. In the following days the Italian Army occupied Innsbruck and all Tyrol with 20 to 22, soldiers. During the six hours between the signing of the armistice and its taking effect, opposing armies on the Western Front began to withdraw from their positions, but fighting continued along many areas of the front, as commanders wanted to capture territory before the war ended.
The occupation of the Rhineland took place following the Armistice. The occupying armies consisted of American, Belgian, British and French forces. In November , the Allies had ample supplies of men and materiel to invade Germany. These factors enabled Hindenburg and other senior German leaders to spread the story that their armies had not really been defeated. This resulted in the stab-in-the-back legend ,   which attributed Germany's defeat not to its inability to continue fighting even though up to a million soldiers were suffering from the flu pandemic and unfit to fight , but to the public's failure to respond to its "patriotic calling" and the supposed intentional sabotage of the war effort, particularly by Jews, Socialists, and Bolsheviks.
The Allies had much more potential wealth they could spend on the war. In the aftermath of the war, four empires disappeared: the German, Austro-Hungarian, Ottoman, and Russian. Numerous nations regained their former independence, and new ones were created. Four dynasties, together with their ancillary aristocracies, fell as a result of the war: the Romanovs , the Hohenzollerns , the Habsburgs , and the Ottomans.
Belgium and Serbia were badly damaged, as was France, with 1. Germany and Russia were similarly affected. A formal state of war between the two sides persisted for another seven months, until the signing of the Treaty of Versailles with Germany on 28 June The United States Senate did not ratify the treaty despite public support for it,   and did not formally end its involvement in the war until the Knox—Porter Resolution was signed on 2 July by President Warren G. However, the negotiation of the treaty with the Ottoman Empire was followed by strife, and a final peace treaty between the Allied Powers and the country that would shortly become the Republic of Turkey was not signed until 24 July , at Lausanne.
Some war memorials date the end of the war as being when the Versailles Treaty was signed in , which was when many of the troops serving abroad finally returned home; by contrast, most commemorations of the war's end concentrate on the armistice of 11 November Legally, the formal peace treaties were not complete until the last, the Treaty of Lausanne, was signed. Under its terms, the Allied forces left Constantinople on 23 August After the war, the Paris Peace Conference imposed a series of peace treaties on the Central Powers officially ending the war.
The Treaty of Versailles dealt with Germany and, building on Wilson's 14th point , brought into being the League of Nations on 28 June The Central Powers had to acknowledge responsibility for "all the loss and damage to which the Allied and Associated Governments and their nationals have been subjected as a consequence of the war imposed upon them by" their aggression. In the Treaty of Versailles, this statement was Article This article became known as the War Guilt clause as the majority of Germans felt humiliated and resentful.
German historian Hagen Schulze said the Treaty placed Germany "under legal sanctions, deprived of military power, economically ruined, and politically humiliated. Active denial of war guilt in Germany and German resentment at both reparations and continued Allied occupation of the Rhineland made widespread revision of the meaning and memory of the war problematic. The legend of the " stab in the back " and the wish to revise the "Versailles diktat", and the belief in an international threat aimed at the elimination of the German nation persisted at the heart of German politics.
Even a man of peace such as [ Gustav ] Stresemann publicly rejected German guilt. As for the Nazis, they waved the banners of domestic treason and international conspiracy in an attempt to galvanise the German nation into a spirit of revenge. Like a Fascist Italy, Nazi Germany sought to redirect the memory of the war to the benefit of its own policies.
Meanwhile, new nations liberated from German rule viewed the treaty as recognition of wrongs committed against small nations by much larger aggressive neighbours. However, owing to economic difficulties and Germany being the only defeated power with an intact economy, the burden fell largely on Germany. Austria-Hungary was partitioned into several successor states, including Austria, Hungary, Czechoslovakia, and Yugoslavia , largely but not entirely along ethnic lines.
Transylvania was shifted from Hungary to Greater Romania. As a result of the Treaty of Trianon , 3. Between and , , Hungarians fled former Hungarian territories attached to Romania, Czechoslovakia, and Yugoslavia. The Russian Empire, which had withdrawn from the war in after the October Revolution, lost much of its western frontier as the newly independent nations of Estonia , Finland , Latvia , Lithuania , and Poland were carved from it. Romania took control of Bessarabia in April The Ottoman Empire disintegrated, with much of its Levant territory awarded to various Allied powers as protectorates.
The Turkish core in Anatolia was reorganised as the Republic of Turkey. This treaty was never ratified by the Sultan and was rejected by the Turkish National Movement , leading to the victorious Turkish War of Independence and the much less stringent Treaty of Lausanne. Even though a lot of countries had already made a peace treaty, there was one exception, Andorra.
Andorra declared war on Germany in August , but, because it had a very small population, Andorra had never sent any soldiers to the battlefield. Because of that, Andorra wasn't allowed to go to the Treaty of Versailles, so the country hadn't made a peace treaty with Germany until When Andorra made the declaration of war, it had an army of part-time militarymen, commanded by two officials. After years, Poland re-emerged as an independent country. The Kingdom of Serbia and its dynasty, as a "minor Entente nation" and the country with the most casualties per capita,    became the backbone of a new multinational state, the Kingdom of Serbs, Croats and Slovenes , later renamed Yugoslavia.
Czechoslovakia, combining the Kingdom of Bohemia with parts of the Kingdom of Hungary, became a new nation. In the British Empire, the war unleashed new forms of nationalism. It was the first major war in which the newly established countries fought, and it was one of the first times that Australian troops fought as Australians, not just subjects of the British Crown. After the Battle of Vimy Ridge, where the Canadian divisions fought together for the first time as a single corps, Canadians began to refer to their country as a nation "forged from fire".
Canada entered the war as a Dominion of the British Empire and remained so, although it emerged with a greater measure of independence. Lobbying by Chaim Weizmann and fear that American Jews would encourage the United States to support Germany culminated in the British government's Balfour Declaration of , endorsing creation of a Jewish homeland in Palestine.
The establishment of the modern state of Israel and the roots of the continuing Israeli—Palestinian conflict are partially found in the unstable power dynamics of the Middle East that resulted from World War I. These continue to be problematic in the 21st-century struggles for national identity. The prestige of Germany and German things in Latin America remained high after the war but did not recovered to its pre-war levels. Germany lost The Australian prime minister, Billy Hughes , wrote to the British prime minister, Lloyd George , "You have assured us that you cannot get better terms.
I much regret it, and hope even now that some way may be found of securing agreement for demanding reparation commensurate with the tremendous sacrifices made by the British Empire and her Allies. Diseases flourished in the chaotic wartime conditions. In alone, louse-borne epidemic typhus killed , in Serbia. Overall, the flu pandemic killed at least 50 million people. The social disruption and widespread violence of the Russian Revolution of and the ensuing Russian Civil War sparked more than 2, pogroms in the former Russian Empire, mostly in Ukraine. In the aftermath of World War I, Greece fought against Turkish nationalists led by Mustafa Kemal , a war that eventually resulted in a massive population exchange between the two countries under the Treaty of Lausanne.
World War I began as a clash of 20th-century technology and 19th-century tactics , with the inevitably large ensuing casualties. By the end of , however, the major armies, now numbering millions of men, had modernised and were making use of telephone, wireless communication ,  armoured cars , tanks ,  and aircraft. Infantry formations were reorganised, so that man companies were no longer the main unit of manoeuvre; instead, squads of 10 or so men, under the command of a junior NCO, were favoured.
Artillery also underwent a revolution. In , cannons were positioned in the front line and fired directly at their targets. By , indirect fire with guns as well as mortars and even machine guns was commonplace, using new techniques for spotting and ranging, notably aircraft and the often overlooked field telephone.
World War I (WW1) Facts, Worksheets, History & Information For Kids
Germany was far ahead of the Allies in using heavy indirect fire. Much of the combat involved trench warfare, in which hundreds often died for each metre gained. Many of the deadliest battles in history occurred during World War I. The Germans employed the Haber process of nitrogen fixation to provide their forces with a constant supply of gunpowder despite the British naval blockade. The large number of head wounds caused by exploding shells and fragmentation forced the combatant nations to develop the modern steel helmet, led by the French, who introduced the Adrian helmet in It was quickly followed by the Brodie helmet , worn by British Imperial and US troops, and in by the distinctive German Stahlhelm , a design, with improvements, still in use today.
Quick, boys! Dim, through the misty panes and thick green light, As under a green sea, I saw him drowning. The widespread use of chemical warfare was a distinguishing feature of the conflict. Gases used included chlorine, mustard gas and phosgene. Relatively few war casualties were caused by gas,  as effective countermeasures to gas attacks were quickly created, such as gas masks. The use of chemical warfare and small-scale strategic bombing as opposed to tactical bombing were both outlawed by the Hague Conventions of and , and both proved to be of limited effectiveness,  though they captured the public imagination.
The most powerful land-based weapons were railway guns, weighing dozens of tons apiece. Trenches, machine guns, air reconnaissance, barbed wire, and modern artillery with fragmentation shells helped bring the battle lines of World War I to a stalemate. The British and the French sought a solution with the creation of the tank and mechanised warfare. The British first tanks were used during the Battle of the Somme on 15 September Mechanical reliability was an issue, but the experiment proved its worth.
Meanwhile, the French introduced the first tanks with a rotating turret, the Renault FT , which became a decisive tool of the victory. The conflict also saw the introduction of light automatic weapons and submachine guns , such as the Lewis Gun , the Browning Automatic Rifle , and the Bergmann MP Another new weapon, the flamethrower , was first used by the German army and later adopted by other forces. Although not of high tactical value, the flamethrower was a powerful, demoralising weapon that caused terror on the battlefield. Trench railways evolved to supply the enormous quantities of food, water, and ammunition required to support large numbers of soldiers in areas where conventional transportation systems had been destroyed.
On the Western Front neither side made impressive gains in the first three years of the war with attacks at Verdun, the Somme, Passchendaele, and Cambrai — the exception was Nivelle's Offensive in which the German defence gave ground while mauling the attackers so badly that there were mutinies in the French Army.
In the Germans smashed through the defence lines in three great attacks: Michael, on the Lys, and on the Aisne, which displayed the power of their new tactics. The Allies struck back at Soissons , which showed the Germans that they must return to the defensive, and at Amiens; tanks played a prominent role in both of these assaults, as they had the year before at Cambrai. The areas in the East were larger. In a series of attacks along with the Bulgarians they occupied Serbia, Albania, Montenegro and most of Romania.
The Allies successes came later in Palestine , the beginning of the end for the Ottomans, in Macedonia, which drove the Bulgarians out of the war, and at Vittorio Veneto, the final blow for the Austro-Hungarians. Germany deployed U-boats submarines after the war began. Alternating between restricted and unrestricted submarine warfare in the Atlantic, the Kaiserliche Marine employed them to deprive the British Isles of vital supplies. The deaths of British merchant sailors and the seeming invulnerability of U-boats led to the development of depth charges , hydrophones passive sonar , , blimps, hunter-killer submarines HMS R-1 , , forward-throwing anti-submarine weapons , and dipping hydrophones the latter two both abandoned in Most of these would be forgotten in the interwar period until World War II revived the need.
Fixed-wing aircraft were first used militarily by the Italians in Libya on 23 October during the Italo-Turkish War for reconnaissance, soon followed by the dropping of grenades and aerial photography the next year. By , their military utility was obvious.
They were initially used for reconnaissance and ground attack. To shoot down enemy planes, anti-aircraft guns and fighter aircraft were developed. Strategic bombers were created, principally by the Germans and British, though the former used Zeppelins as well. Manned observation balloons , floating high above the trenches, were used as stationary reconnaissance platforms, reporting enemy movements and directing artillery.
Balloons commonly had a crew of two, equipped with parachutes ,  so that if there was an enemy air attack the crew could parachute to safety. At the time, parachutes were too heavy to be used by pilots of aircraft with their marginal power output , and smaller versions were not developed until the end of the war; they were also opposed by the British leadership, who feared they might promote cowardice. Recognised for their value as observation platforms, balloons were important targets for enemy aircraft.
To defend them against air attack, they were heavily protected by antiaircraft guns and patrolled by friendly aircraft; to attack them, unusual weapons such as air-to-air rockets were tried. Thus, the reconnaissance value of blimps and balloons contributed to the development of air-to-air combat between all types of aircraft, and to the trench stalemate, because it was impossible to move large numbers of troops undetected.
The Germans conducted air raids on England during and with airships, hoping to damage British morale and cause aircraft to be diverted from the front lines, and indeed the resulting panic led to the diversion of several squadrons of fighters from France. All German survivors were summarily executed by Baralong ' s crew on the orders of Lieutenant Godfrey Herbert , the captain of the ship.
The shooting was reported to the media by American citizens who were on board the Nicosia , a British freighter loaded with war supplies, which was stopped by U just minutes before the incident. On 24 September, Baralong destroyed U , which was in the process of sinking the cargo ship Urbino. According to Karl Goetz, the submarine's commander, Baralong continued to fly the US flag after firing on U and then rammed the lifeboat—carrying the German survivors—sinking it. Only 24 of the medical personnel, patients, and crew survived. Survivors reported that the U-boat surfaced and ran down the lifeboats, machine-gunning survivors in the water.
The U-boat captain, Helmut Patzig , was charged with war crimes in Germany following the war, but escaped prosecution by going to the Free City of Danzig , beyond the jurisdiction of German courts. After the war, the German government claimed that approximately , German civilians died from starvation and disease during the war because of the Allied blockade.
All food consigned to Germany through neutral ports was to be captured and all food consigned to Rotterdam was to be presumed consigned to Germany. The British were determined on the starvation policy, whether or not it was lawful. The first successful use of poison gas as a weapon of warfare occurred during the Second Battle of Ypres 22 April — 25 May It is estimated that the use of chemical weapons employed by both sides throughout the war had inflicted 1. For example, the British had over , chemical weapons casualties during the war, and up to one-third of American casualties were caused by them.
The effect of poison gas was not limited to combatants. Civilians were at risk from the gases as winds blew the poison gases through their towns, and they rarely received warnings or alerts of potential danger. In addition to absent warning systems, civilians often did not have access to effective gas masks. An estimated ,—, civilian casualties were caused by chemical weapons during the conflict and tens of thousands more along with military personnel died from scarring of the lungs, skin damage, and cerebral damage in the years after the conflict ended.
Many commanders on both sides knew such weapons would cause major harm to civilians but nonetheless continued to use them. British Field Marshal Sir Douglas Haig wrote in his diary, "My officers and I were aware that such weapons would cause harm to women and children living in nearby towns, as strong winds were common in the battlefront. However, because the weapon was to be directed against the enemy, none of us were overly concerned at all. The ethnic cleansing of the Ottoman Empire's Armenian population, including mass deportations and executions, during the final years of the Ottoman Empire is considered genocide.
The Armenians were intentionally marched to death and a number were attacked by Ottoman brigands. Other ethnic groups were similarly attacked by the Ottoman Empire during this period, including Assyrians and Greeks , and some scholars consider those events to be part of the same policy of extermination.
The German invaders treated any resistance—such as sabotaging rail lines—as illegal and immoral, and shot the offenders and burned buildings in retaliation. In addition, they tended to suspect that most civilians were potential francs-tireurs guerrillas and, accordingly, took and sometimes killed hostages from among the civilian population. The German army executed over 6, French and Belgian civilians between August and November , usually in near-random large-scale shootings of civilians ordered by junior German officers.
The German Army destroyed 15,—20, buildings—most famously the university library at Louvain —and generated a wave of refugees of over a million people. Over half the German regiments in Belgium were involved in major incidents. British propaganda dramatising the Rape of Belgium attracted much attention in the United States, while Berlin said it was both lawful and necessary because of the threat of franc-tireurs like those in France in The British soldiers of the war were initially volunteers but increasingly were conscripted into service.
Surviving veterans, returning home, often found they could discuss their experiences only amongst themselves. Grouping together, they formed "veterans' associations" or "Legions".
