In October 1917, Edmund Allenby, commander of Britain's Egyptian Expeditionary Force, planned to attack the Ottomans in southern Palestine. Rather than repeat previous frontal assaults at Gaza, which had been unsuccessful, he planned a flanking attack at Beersheba. As part of the larger deception effort to convince the Ottomans that Gaza was his objective, an officer under Allenby's command executed a deceptive tactic now known as the Haversack Ruse. In this effort, usually attributed to Richard Meinertzhagen, the officer intentionally dropped a knapsack which contained false plans for an attack on Gaza, which the Ottomans recovered. As a result of the Haversack Ruse and other deceptive measures, the British surprised the Ottomans and achieved victory at the October 31, 1917 Battle of Beersheba.
