7. Why the US gets involved During the war, a ship called Lusitania-a passenger ship that was secretly carrying ammunitions- was sunk by a German submarine. This caused 1,198 to die. 128 of those people were American. After the incident, President Wilson demanded that the Germans apologize and pay for the damage that was caused. After this, the Sussex pledge was enforced. The Sussex pledge was that Germany had to promise to warn before sinking any merchant ships before getting passengers safely off-board. By 1917, Germany was defeating Russia on the eastern front, and wanted restrictions for attacks on the western front. They used unrestricted submarine warfare at this moment, sinking all ships that were headed to the allied nations. Zimmerman was a German official who sent a letter to mexico asking them to attack the U.S. He promised that in return Germany would aid them to retrieve some of the land that was taken from them.

8. Trench Warfare Trenches were dug in the fighting fields to cut down on the losses of soldiers for both side of the war. The conditions of these trenches were horrendous. The small areas were very unsanitary and also disease filled. During the night-time, supplies were brought in and soldiers were sent out. In dawn/dusk, artillery was thrown from the opposing soldiers over the top of the trenches. Among the problems were: rats, smell of body rot, staying dry, maggots, lice, and many diseases.
