In late April 1918, the brigade was deployed into the Jordan Valley and between 29 April and 4 May took part in the raid on Es Salt. Defensive positions were occupied on the western bank of the Jordan River throughout June and July, before the brigade left the Jordan Valley in mid-August. Around this time, the troopers were issued swords and received cavalry training, in preparation for a renewed offensive aimed at capturing Damascus. In mid-September, the brigade took part in the advance towards Semakh and Tiberias and on 25 September the brigade took part in the Battle of Samakh – a minor action that formed part of the Battle of Sharon and the wider Battle of Megiddo – where the 11th Light Horse carried out a mounted charge with drawn swords before dismounting and clearing the town with rifles and bayonets. The 4th and 12th Light Horse were heavily engaged on 30 September, carrying out a charge at Kaukab. The next day, elements of the 4th Light Horse Regiment carried out a patrol to Damascus, while the 12th also entered the town on 2 October. The brigade remained in Damascus for most of October, before joining the final stage of the campaign which saw the brigade begin the advance towards Homs on 27 October. The advance was short lived, as on 30 October the Ottomans surrendered, and the Armistice of Mudros came into effect, bringing an end to the fighting in the theatre.
