Asiatic and Egyptian Theaters
First Battle of Gaza ends (see 26th, and April 17th). Ottoman counterattacks recaptured Ali Muntar and a portion of Green Hill, but the 1/7th Battalion of the Essex Regiment, (161st Brigade, 54th Division), retook the positions before consolidating and re-establishing their posts. Meanwhile the Ottoman force, appeared on Sheikh Abbas and shelled the rear of the British position, "including his reserves, medical units and transport camels." The Turkish artillery batteries at Sheikh Abbas targeted all the tracks across the Wadi Ghuzzeh, employed by the Egyptian Camel Transport Corps, who were at the time attempting to supply food, water and ammunition, to the forward units. Turkish presence and severe command confusion among the British eventually prompted the withdraw of all efforts to attack Gaza.
