At the same time, the Ottoman Fourth Army was preparing a force of 20,000 men under the command of the Ottoman Minister of the Marine, Djemal Pasha, to take the Suez Canal. The attack on Suez was suggested by War Minister Enver Pasha at the urging of their German ally. The chief of staff for the Ottoman Fourth Army was the Bavarian Colonel Kress von Kressenstein, who organised the attack and arranged supplies for the army as it crossed the desert.
