1. Unit IV: 1915 “A War to End All Wars” -H.G. Wells 1

2. Unit IV 1915: LEARNING TARGETS: 1. I can explain how even though the war begins in Europe it evolves into a World War with some very strange outcomes in strange places. 2. I understand why the alliance between the Central Powers and the Ottoman Empire is seen as an opportunity for France and Britain to carve it up. 3. I understand and can explain how trench warfare created a lifestyle and a reality that no volunteer and no General had planned for or could react well to. 4. I understand and can explain how the new technology made war 3-dimensional and why neither the air above or the sea below were safe. 2
