In February 1918, the Somerset Battery was detached from XVIII Brigade, Royal Horse Artillery (T.F.), replacing the Leicestershire Battery. In the middle of the month, the brigade took part in the capture of Jericho, during which the Anzac Mounted Division was placed on the right of two British infantry divisions, pushing through a large gorge near the Dead Sea towards Rujm el Bahr. At the end of the month, the brigade pushed further west and took part in the failed First Battle of Amman during the First Transjordan attack on Amman. This was followed by the raid on Es Salt in April and May, and then launched a counterattack on 14 July during the Battle of Abu Tellul following an attack by two Ottoman divisions. Following this, the Allies renewed their offensive, during which the Anzac Mounted Division was assigned to a mixed force that became known as Chaytor's Force to join the Third Transjordan attack, supporting the main drive towards Damascus further to the north. The Australian Mounted Division who were advancing along the coast, employed cavalry tactics, having been issued swords and trained in their use in August; however, the Anzac Mounted Division continued to be employed as mounted rifles. In late September, the brigade took part in the Second Battle of Amman. During their final battle of the war, the brigade helped clear the west bank of the Jordan, before crossing the river at Uniin esh Sher and then advanced to Es Salt, before later advancing to Suweile and supporting the capture of Amman. On 30 October, the Ottomans surrendered, and the Armistice of Mudros came into effect, bringing an end to the fighting in the theatre.
