Look at your textbook page 375 (MAP)TRENCH WARFARE
(page 376)3 Main kinds of
trenches-Front Line-Support-Reserve
THE BATTLE OF SOMME•1st Battle- Began July 1, 1916•British suffered 60,000 casualties in the first day alone•1.2 million total•Only 7 miles of ground exchanged because of trench warfare
TRENCH WARFARE• “NO MAN’S LAND”-a barren expanse of mud
with shell craters and filled with barbed wire
Americans Question Neutrality• Public opinion was strong-but divided• Socialists criticized the war as capitalist and
imperialist struggle between Germany and England to control markets
• Pacifists believed that war was evil and the US should set an example for world peace
• Millions of naturalized citizens followed the war closely because they still had ties with other nations
• America had strong economic ties to the Allies• During the first two years of war the Allies
flooded American markets with supply orders
THE WAR HITS HOME• In 1917 America had mobilized for war for 2 reasons
– To ensure Allied repayment of debts to the U.S.– To prevent the Germans from threatening U.S. shipping
THE BRITISH BLOCKADE•Made use of naval strength•Blockaded German coast to prevent weapons and other supplies from getting through•Americans were angry b/c blockade threatened freedom of the seas
GERMAN U-BOAT RESPONSE•Germans responded with a counterblockade •May 7, 1915 U-Boat sank the British liner Lusitania off the coast of Ireland•128 Americans were lost•Americans became outraged and public opinion turned against Germany
1916 Election• Democrats renominated Woodrow
Wilson• Republicans nominated Charles
Evans Hughes• Wilson campaigned under the
slogan “He Kept Us Out Of War”• Wilson was elected and hoped that
all nations would join a “league for peace” which would work to extend democracy, maintain freedom of the seas and reduce armaments
The United States Declares War• Germans ignored Wilson’s call for peace
and threatened to sink all ships entering British waters
• Zimmerman Note-telegram from the German foreign minister to the German ambassador in Mexico that was intercepted by British agents– Telegram promised that if war with the
United Sates broke out, Germany would support Mexico in recovering “lost territory in Texas, New Mexico and Arizona”
–Four more US merchant ships were sunk with 36 lives lost
–Russia replaced there monarchy with a representative government
Now the United States could justify that this war was a war of democracies against brutal
monarchies“Make the World Safe For Democracy”
