1908, the regiment simply dropped 'Imperial' from its title. It was attached to the London Mounted Brigade for training, but was otherwise under the command of London District. World War I Mobilisation The Westminster Dragoons' summer camp in 1914 was at Goring-on-Thames. It began on 25 July, but the regiment was recalled to Westminster when mobilisation orders arrived on 5 August. The regiment reorganised on the three-squadron basis used by the Regular cavalry and purchased horses. In accordance with the Territorial and Reserve Forces Act 1907 (7 Edw. 7, c.9), which brought the Territorial Force into being, the TF was intended to be a home defence force for service during wartime and members could not be compelled to serve outside the country. However, on the outbreak of war on 4 August 1914, many members volunteered for Imperial Service. Therefore, TF units were split in August and September 1914 into 1st Line (liable for overseas service) and 2nd Line (home service for those unable or unwilling to serve overseas) units. Later, a 3rd Line was formed to act as a reserve, providing trained replacements for the 1st and 2nd Line regiments. 1/2nd County of London Yeomanry Egypt The regiment sailed on 10 September for Egypt, thereby being one of the first Yeomanry regiments to go overseas on active service.

The regiment carried out security and escort duties in Cairo and patrols on the fringe of the Sinai Desert to protect the Suez Canal. The brigade joined the 2nd Mounted Division on 13 August and was redesignated as the 5th (Yeomanry) Mounted Brigade. It was dismounted to take part in the Gallipoli Campaign, leaving a squadron HQ and two troops (about 100 officers and men) in Egypt to look after the horses. Gallipoli The regiment sailed from Alexandria on 14 August, arriving at Mudros on 17 August. It landed at "A" Beach, Suvla Bay the following day and moved into reserve positions at Lala Baba on the night of 20 August. On 21 August, it advanced to Chocolate Hill and was in reserve for the attacks on Scimitar Hill and Hill 112. Due to losses during the Battle of Scimitar Hill and wastage during August
