In 1915, the Turkish armies in Palestine, under German leadership, attempted to gain possession of the Suez Canal, in order to prevent supplies passing through on Allied ships. Although the Turks made several attempts to block the canal, they were all unsuccessful. After these numerous attacks on the canal, England realized that the only safe way to protect her Egyptian possessions was to gain Palestine. In 1916 a plan was made for an offensive into the Holy Land. The plan was first tried by General Maxwell and then by General Murray, but both attempts were unsuccessful. In June, 1917, the English transferred General Allenby, then fighting on the western front, to the command of the Egyptian expeditionary forces. He immediately began to lay plans for an offensive into Palestine, with the city of Jerusalem as his main objective. The Turks were strongly fortified in southern Palestine, on a line extending from the coast city of Gaza to the inland city of Beersheba. Allenby's plan was to attack the left flank of the enemies' line, capturing Beersheba, where he counted on renewing his water supply. To aid the successful advancement of his main offense, he sent a small body of troops toward the city of Gaza, situated on the enemies' right flank. This was done to draw the Turkish reserves toward Gaza, where they would expect the main offense to take place. The British warships in the Mediterranean helped in this movement, by bombarding the town as the land forces approached it. The plan was put into effect on October 30. On the next day the city of Beersheba was taken by surprise, and the Turkish left flank was routed. After renewing his supply of water at Beersheba, General Allenby advanced on Gaza, which was captured with little resistance. Although greatly hampered by poor water supply and tremendous transportation difficulties, he drove the Turks north and by a successful engagement at Junction Station cut their forces in two. By this time the Turks in Jerusalem were becoming greatly disturbed by Allenby's rapid advance. Enver Pasha, the famous Turkish commander, rushed to the city to rally his generals, but after studying the situation, he left the city the next day. Soon after Enver's hurried departure, General Falkenhayn arrived. Military supplies were moved north of the city and the Germans prepared to leave. The remaining Turks were under the command of Ali Fuad Pasha, who by proclamations and entreaties, tried to rally the people of the city.
