After securing the capture of Jerusalem General Allenby planned a campaign that would knock Turkey out of World War 1. In a spectacular campaign General Allenby's Egyptian Expeditionary Force achieved the breakthrough in Palestine that commanders on the Western Front had only dreamed of. Supported by Lawrence and his Arab irregulars, the Desert Mounted Corps swept across the Turkish rear, destroying three armies in the process. Turkey's war was over and the days of the tottering Ottoman Empire were numbered. This was a British 'Blitzkrieg' with a speed of advance that stunned the world twenty years before Germany's Panzers rolled across Europe.
