World War I: A Global Struggle

While the armies clashed in Europe, fighting also raged across the belligerents' colonial empires. In Africa, British, French, and Belgian forces captured the German colonies of Togoland, Kamerun, and South-West Africa. Only in German East Africa was a successful defense mounted, where Colonel Paul von Lettow-Vorbeck's men held out for the duration of the conflict. In the Middle East (right), British forces clashed with the Ottoman Empire. After the failed campaign at Gallipoli, the primary British efforts came through Egypt and Mesopotamia. After victories at Romani and Gaza, British troops pushed into Palestine and won the key Battle of Megiddo. Other campaigns in the region included fighting in the Caucasus and the Arab Revolt.
