3. Technology of War Airplane – Initially used as reconnaissance planes. – After the “interrupter was invented they could position guns through the prop. (Combat planes) – Telsa (seen later) would also introduce a plane, showing a wing that pivoted. Tank – United Kingdom develops this to run over the trenches. Armor-plating helps in “no- man’s land”

4. Technology of War Machine Gun – Utilized by all sides, one man now had the power of forty soldiers. – Battle of the Somme in 1916. Zeppelin – Used extensively by Germany in WWI. – Quiet, high altitude, and ability to complete bombing raids. – Huge flammable dirigible, no smoking…

5. Technology of War Mustard Gas – Only used when appropriate. – Wind direction, troop movements. – Initial gas masks utilized cloths soaked in urine to repel the gas. Flame Thrower – Used to chase people out of a trench, then open fire with machine guns.

6. Technology of War The Electric War – 1890s, Westinghouse purchased AC technology from Nikola Tesla. – Went against Edison’s DC power supply. (Good for short distance) Alternating Current was seen as more efficient over long distances. – Edison would wage campaign against AC, claiming it to be highly dangerous and used in the Electric Chair. – Truth is, they didn’t know what type of electricity was used in the chair… In World War I – Tesla developed a “radar” based system for torpedoes, but it was not adopted.

7. A Global Conflict Early 1915, Italy supports the Allies (Triple Entente) Gallipoli Campaign- – Take the Dardenelles Strait so a supply route is established to Russia. – It lasts nearly 10 months, with no success. Allied armies (Triple Entente) manage to control the Middle East from the Turks.

8. Using the Colonies Imperial Nations such as Britain and France would use the people they forced into servitude to fight in the Great War. Some volunteered, hoping for independence.

9. The United States Enters War 1915, unrestricted submarine warfare would lead to the sinking of the passenger ship Lusitania. – 128 Americans killed. – While many were outraged, the ship was carrying war supplies. 1917, Germany sends Zimmerman telegram to Mexico. “Keep America occupied, so they don’t declare war on Germany.”

10. Zimmerman telegram caused the US to enter war on the Allied side. (Triple Entente) Americans that wanted to stay out of war joined in droves to fight in the conflict. (They still had the romanticized idea of war)
