At this battle, the retreating Senussi were attacked by the Dorset Yeomanry with drawn swords across open ground. Under fire, the Yeomanry lost half their horses, and about a third of their men and officers were casualties (58 of the 184 who took part). Colonel Soutar, leading the regiment in this charge, had his horse shot from under him and was knocked unconscious. When he came to, he found himself alone amongst a group of the enemy. He drew his revolver, shot several, and took the Turkish leader Jaffir Pasha prisoner. In February 1917, 6th Mounted Brigade joined the Imperial Mounted Division and took part in the First and Second Battles of Gaza. I, June 1917, it was transferred to the Yeomanry Mounted Division for the Third Battle of Gaza and the Battle of Beersheba. In July 1918, the Brigade was re-designated the 10th Cavalry Brigade and the Division the 4th Cavalry Division. The Regiment remained with them in Palestine until the end of the war. The 2nd Line regiment was formed at Sherborne in September 1914. In May 1915, it was at Chippenham, where it joined the 2/1st South Western Mounted Brigade, then it moved to Maresfield in September. In October 1915, it joined the 1/1st South Western Mounted Brigade (replacing the 1/1st Royal Wiltshire Yeomanry) and the brigade was redesignated as 2/1st Southern Mounted Brigade. On 31 March 1916, the remaining Mounted Brigades were ordered to be numbered in a single sequence; the brigade became the 16th Mounted Brigade and joined 4th Mounted Division at Manningtree. In July 1916, there was a major reorganization of 2nd Line yeomanry units in the United Kingdom. All but 12 regiments were converted to cyclists and as a consequence the regiment was dismounted and joined the 7th Cyclist Brigade (and the division became 2nd Cyclist Division) at Woodbridge. Further reorganization in November 1916 saw the 2nd Cyclist Division broken up and the regiment was remounted at Maidstone, taking over the horses of the 2/1st Queen's Own West Kent Yeomanry and replacing it in 3rd Mounted Brigade in the new 1st Mounted Division (3rd Mounted Division redesignated). In March 1917, it was at Sevenoaks. In September 1917, the regiment was converted back to cyclists, this time in 13th Cyclist Brigade in The Cyclist Division, still at Sevenoaks.
