mounted. Following this, the regiment undertook basic training including weapons handling, ceremonial drill, mounted and dismounted tactics and regimental manoeuvres. In late April, they marched through the centre of Sydney as part of a farewell before deploying overseas. On 11 June, after the brigade had concentrated, the regiment embarked upon the troopship SS Suevic. After four days steaming, the ship put into Adelaide, South Australia, where the regiment disembarked their horses due to concerns about death rates among horses travelling at that time of year. The men continued on their journey three days later, undertaking rifle and signals training on deck during the day. They crossed the equator in the early afternoon on 5 July; a short time later an epidemic of measles broke out. On 11 July, the 4th Light Horse Brigade received orders to interrupt its journey to Egypt and instead disembark at Aden, where an Ottoman attack was expected. They were briefly put ashore during this time and conducted a reconnaissance to the frontier, before undertaking a route march. The expected attack did not come and on 18 July the regiment re-embarked, arriving at Suez on 23 July. Moving into a camp at Heliopolis, near Cairo, after receiving a draft of 54 reinforcements and about 350 replacement horses, the regiment began a period of intense training and guard duties as they acclimatised to the local conditions. Gallipoli Elsewhere, the Gallipoli campaign had developed into a stalemate. The regiments of the 1st, 2nd and 3rd Light Horse Brigades had already been sent to the peninsula as reinforcements; however, the failed August Offensive had resulted in heavy casualties for the Australians and further reinforcements were required. As a result, the regiments of the 4th Light Horse Brigade were broken up to make up the losses in the other brigades. The troops were not initially informed of this, and following a train trip to Alexandria on 25 August they embarked upon the transport SS Marquette and sailed to Lemnos Island where they were transferred to Prince Abbas. Early on the morning of 29 August, the regiment went ashore at Anzac Cove upon lighters, and later that afternoon received the news that they were to be broken up and distributed among the other New South Wales light horse regiments that were already ashore. The Machine-Gun Section and 'A' Squadron were sent to the 1st Light Horse Regiment around "Walker's Ridge", becoming
