World War I

1. World War I The Americans in Europe

2. Trench Warfare • Both the French and the German troops become bogged down in the trenches craved into the landscape • Both sides will be kept in almost the same position for four years • Technology superior to tactics • Machine gun versus a human charge through "No man's land" • New technology = poison gas, airplanes • Very high death rates • Battle of the Somme = 600,000 allied and 500,000 German dead for 125 miles of land • Battle of Verdun = 700,000 killed on both sides with no gain in territory

7. Poison Gas • Chlorine – greenish-yellow gas (heavier than air). Gas reacted in the presence of water to cause a chemical burning effect on organic matter. Human body was susceptible because it is organic and is always covered with a film of water. • Symptoms: vomiting, difficulty breathing, burning sensation in the lungs, eyes, nasal/mouth passages, and watery eyes. Severe cases included cell damage in lung leading to fluid buildup, loss of consciousness through suffocation, and death • Phosgene – colorless, odorless, gas (heavier than air). It is highly poisonous because it will replace the oxygen in cells and quickly cause an oxygen debt within the body, leading to unconsciousness and death • Mustard Gas – Caustic gas with a distinctive mustard smell. It causes blistering and huge sores on any exposed tissue, internal, or external. This was the most commonly used gas, along with phosgene, during WWI.

21. Tactics of Trench Warfare • Trench warfare confused military leaders who were trained to fight wars of movement and maneuvering • Officers would sometimes order an artillery attack to flatten the enemy’s barbed wire and leave the enemy in a state of shock • After “softening up” the enemy, many soldiers would climb out of the trench with fixed bayonets hoping to work their way to the enemy • Attacks rarely worked because men would have to advance through unprotected, open fields • The French lost 700,000 men at Verdun in only a few miles of land • War of attrition  war based on wearing the other side down by constant attacks and heavy losses

22. Winning the War at Sea • No American troopships were sunk on the way to Europe because of the efforts of Admiral William S. Sims • Organized merchant ships and troop transports into groups known as convoys • If a ship was sunk, the survivors could be quickly rescued by other members of the convoy

23. Russia Leaves the War • March, 1917  Riots broke out in Russia over the government’s handling of the war • Forced the abdication of Czar Nicholas II • Bolshevik Party, led by Vladimir Lenin, overthrew provisional government and established a communist government in Russia • Russia signed the Treaty of Brest-Litovsk to exit the war with Germany

24. Americans Enter the War • General John J. Pershing commanded the American Expeditionary Force (AEF) • Arrived in Paris on July 4, 1917 • British and French troops wanted to integrate Americans into armies headed by British/French leaders • Pershing refused • Only the 93rd Infantry Division were given to the French

25. Germany’s Last Offensive • March 12, 1918  Germans launched massive attack on the Western Front • Late May  Americans launched a counter-attack, capturing the village of Cantigny • June 1  American and French troops blocked German advance • July 15  Germans launched one last attempt on Paris, but the Americans and French pushed them back

26. The Battle of Argonne Forest • French Marshal Ferdinand Foch ordered a massive counterattack • Mid-September  American troops drove back German forces at the battle of Saint-Mihiel • General Pershing created a major offensive in the region of the Argonne Forest • Attack began on September 26, 1918 • By November, Americans had destroyed the German defenses, forcing a German retreat

27. American Heroes • Alvin York • Opposed to war, he initially tried to avoid the draft as a conscientious objector (someone who refuses to obey the law because of his moral or religious beliefs) • October 8, 1918  German machine guns killed nine men in the same platoon as York • York killed between 9-25 Germans, captured the machine guns, and took 132 prisoners • Received the Medal of Honor and the French Croix de Guerre for his actions • Eddie Rickenbacker • Famous car driver before the war • Became commander of the 94th Aero Squadron • Fought in 134 air battles and shot down 26 enemy aircrafts • In one battle, he single-handedly fought seven German aircrafts • He received the Congressional Medal of Honor

28. The War Ends • October 1918  Poland, Hungary, and Czechoslovakia declared independence • Early November  Austro-Hungarian and Ottoman empires surrendered to the Allies • November 3  Sailors in Kiel mutinied, leading to a nation-wide rebellion • November 9  Germany became a republic • November 11  Germany signed an armistice (a truce, or agreement to stop fighting)

29. A Flawed Peace • January 1919, delegates from over 27 nations attended a peace conference in Paris • Allies and the Germans sign the Treaty of Versailles to end the war • Big Four Powers  Wilson (US), Lloyd George (UK), Clemenceau (France), and Orlando (Italy)

30. The Fourteen Points • President Wilson's plan for peace • Believed that his fourteen points would establish a lasting peace for Europe • Based on “the principle of justice to all peoples and nationalities” • First five points  Proposed to eliminate the causes of the war through free trade, freedom of seas, disarmament, an impartial adjustment of colonial claims, and open diplomacy instead of secret agreements • Next eight points  addressed the right of national self-determination (the borders of countries should be based on ethnicity and national identity) • No nation should be to take territory from another nation • Fourteenth point  creation of the League of Nations • “a general association of nations” to help preserve peace by pledging to respect and protect each other’s territory and political independence

31. Treaty of Versailles • Lloyd George and Clemenceau wanted to punish the Germans for the suffering endured during the war • Britain refused to give up sizable naval advantage and France wanted to end German threat forever • Treaty of Versailles was signed on June 28, 1919 • Designed to punish and weaken Germany • Germany was not allowed to put troops on the Rhine River • German must take the blame for the war • Germany must pay reparations (monetary compensation for all damages of war) • Germany must give up some eastern land to Poland

32. US Senate Rejects the Treaty • The largely Republican senate refused to ratify the treaty mostly based on the League of Nations • Opponents pointed out the Congress was the only body of government to be able to declare war, but the League of Nations could require a member country to go to war • After multiple failed attempts to ratify the treaty, the United States eventually negotiated separate treaties with the Central Powers
