Sinai and Palestine Campaign - Ottoman Force June 1918

Five of the six brigades in the 4th and 5th Cavalry Divisions were composed of one British yeomanry and two Indian cavalry regiments.[345] The sixth brigade (in the 5th Cavalry Division), the 15th (Imperial Service) Cavalry Brigade, consisted of three regiments of Imperial Service Troops, which represented and were wholly maintained by the Indian Princely states of Jodhpur, Mysore and Hyderabad.[345] Eight of the 18 regiments in the six brigades were armed with and called lancers.[345][Note 13] The Australian Mounted Division's 5th Mounted Brigade was also dismounted and sent to reinforce the British Expeditionary Force in France. It was replaced by the newly formed 5th Light Horse Brigade which consisted of the 14th and 15th Light Horse Regiments, formed from Australians transferred from the Imperial Camel Corps Brigade and the French Régiment Mixte de Marche de Cavalerie. Completing this division, the 3rd and 4th Light Horse Brigades consisted of three light horse regiments made up of a headquarters and three squadrons. To conform with the 5th Light Horse Brigade, the 522 troopers in each of these regiments were armed with swords instead of bayonets,[346][347][348] and Lee–Enfield rifles.[349]
