Following an unsuccessful attack on Medina, forces of the Arab Revolt under Emir Faisal I were on the defensive against the Turks. In the spring of 1917, Arab forces moved north to seize the Red Sea ports of Yenbo and Wejh, allowing them to regain the initiative, but neither the Arabs nor their British allies could agree on a subsequent plan of action. The Arabs began a series of attacks on the Hejaz Railway, and contemplated another campaign against Medina, but with British troops stationary in front of Gaza, it seemed they weren't in a position to succeed. The Turkish government had sent Arab divisions of its army, which held many pro-Revolt units, to the front lines, depriving Faisal and his allies of much-needed reinforcements.
