The battalion was authorized on 10 August 1914, and embarked for
Britain on 29 September 1914. It formed the nucleus of the Remount Depot on 20 January 1915, and the remainder of the battalion's personnel were absorbed by the Canadian Cavalry Depot, CEF, on 6 March 1915 to provide reinforcements for the
Canadian Corps in the field. The battalion was disbanded on 5 April 1918. The band of the
106th Regiment Winnipeg Light Infantry received permission to go overseas with the battalion, and in January 1915 transferred to the
10th Battalion, CEF. The battalion recruited in
Portage la Prairie,
Roblin,
Pipestone and
Winnipeg, Manitoba;
Lloydminster, Saskatchewan; and
Pincher Creek, Alberta; and was mobilized at
Camp Valcartier, Quebec. Most of the recruits came from detachments from at least six different cavalry militia regiments from across Western Canada: the
34th Fort Garry Horse, the
20th Border Horse, the
18th Manitoba Mounted Rifles, the
32nd Manitoba Horse, the
15th Canadian Light Horse from Alberta, and the
22nd Saskatchewan Light Horse. The 6th Battalion was commanded by Lieutenant-Colonel
J. G. Rattray and by Lieutenant-Colonel R. W. Paterson. == Perpetuations ==
