The Ottoman Seventh Army formed a new provisional combat detachment designed to counter-attack into the British flank. On 1 May the Ottoman troops which pushed in the 4th Light Horse Brigade's flank guard near Jisr ed Damieh, were the Ottoman 3rd Cavalry Division and part of an infantry division (probably the VIII Corps' 48th Division) part of whom continued on up the road to attack Es Salt. While the remainder of the Egyptian Expeditionary Force held the front line from the Mediterranean Sea to the Dead Sea and garrisoned the captured territories, Chauvel the commander of Desert Mounted Corps, replaced Chetwode, who was the commander of the XX Corps, as commander of the Jordan Valley. Chauvel took command of the Jordan Valley, as well as responsibility for second Transjordan operations. Chauvel's force was one mounted division stronger than the one that attacked Amman the month before, consisting of –  The following units were attached to the Australian Mounted Division for their attack on Es Salt: the 1st Light Horse Brigade from the Anzac Mounted Division, the Mysore and Hyderabad lancers, from the Imperial Service Cavalry Brigade, the Dorset and Middlesex Yeomanry from the 6th, the 8th Mounted Brigades, the Hong Kong and Singapore Mountain Artillery Battery and the 12th Light Armoured Motor Battery. In addition to this attacking force, stationed on the west bank of the Jordan River to guard the left flank were the Imperial Camel Corps Brigade with the 22nd Mounted Brigade. The XIX Brigade RHA comprising the 1/1st Nottinghamshire Royal Horse Artillery and "1/A" and "1/B" Batteries, Honourable Artillery Company, were attached to the 4th Light Horse Brigade to support its defence of the northern flank in the Jordan Valley. After their return from the first Transjordan raid, the Anzac Mounted Division remained in the Jordan Valley; camped near Jericho and were involved in the demonstration against Shunet Nimrin on 18 April. The Australian Mounted Division, which had been in rest camp near Deir el Belah from 1 January to April, moved via Gaza and Mejdel to Deiran from Jaffa in preparation to take part in the attacks northwards towards Tulkarem, known by the Ottomans as the action of Berukin from 9 to 11 April, however the engagement did not develop to a point where the mounted division could be deployed.
