Following the Battle of Rafa, the 5th Mounted Brigade transferred from corps troops to the Imperial Mounted Division (renamed in June to the Australian Mounted Division) in the Desert Column (reorganised in August as the Desert Mounted Corps). On 26 March, the mounted divisions, less the Royal Gloucestershire Hussars, invested Gaza from the east and north in the First Battle of Gaza. The regiment, attached to the 53rd (Welsh) Infantry Division, was deployed along the coast, covering the division's left flank as it attacked Gaza from the south. The attempt to capture Gaza suffered from delays caused by fog, and the attack was called off in the late afternoon. The Second Battle of Gaza in April, during which the regiment fought with the rest of the cavalry as mounted infantry on the right flank of the main infantry attack, fared no better, and the opposing sides settled into a period of inaction.
