The defeat of the Al Rashidi doubled the size of Saudi territory because, after the war of Ha'il, Ibn Saud sent his army to occupy Al-Jouf and the army led by Eqab bin Mohaya,[clarification needed] the head of Talhah tribe. This allowed Ibn Saud the leverage to negotiate a new and more favorable treaty with the British. Their treaty, signed at Uqair in 1922, where he met Percy Cox, British High Commissioner in Iraq, to draw boundaries[18] saw Britain recognize many of his territorial gains.
