 The 2nd Light Horse Brigade and Patiala Infantry, (Chaytor's Force) advanced on 20 September eastwards across the Jordan Valley toward the strongly entrenched Shunet Nimrin position, and Derbasi on the Ottoman left flank. The 6th Light Horse and 7th Light Horse Regiments, with a company of Patiala Infantry, were shelled by guns from El Haud in the foothills of Moab as they moved across the valley. Positions east of the Jordan River, including Mellaha, continued to be strongly held by Fourth Army units.
