The Manitoba Mounted Rifles was a cavalry regiment of the Non-Permanent Active Militia of the Canadian Militia and later the Canadian Army. In 1946, the regiment was converted to artillery.[1] [2]
The regiment was first formed on 2 April 1907, originally as the 18th Manitoba Mounted Rifles.[5] The regimental headquarters was established at Winnipeg and had squadrons established in Winnipeg, Dominion City, Portage la Prairie and Morden, Manitoba.
At the start of the First World War, the 18th Mounted Rifles was one of six cavalry regiments from across Western Canada to provide detachments to help form the 6th Battalion (Fort Garrys), CEF for service in the first contingent of the Canadian Expeditionary Force. The other detachments were provided from the 34th Fort Garry Horse (now The Fort Garry Horse), the 20th Border Horse (now part of the 12th Manitoba Dragoons), the 32nd Manitoba Horse (now part of The Fort Garry Horse), the 15th Canadian Light Horse (now the South Alberta Light Horse), and the 22nd Saskatchewan Light Horse (now part of The North Saskatchewan Regiment).[6]
On 7 November 1914, the 1st Regiment, Canadian Mounted Rifles, CEF was authorized, and on 12 June 1915, the regiment embarked for the United Kingdom. On 22 September 1915, the 1st Regiment, CMR disembarked in France where it fought as part of the 1st Brigade, Canadian Mounted Rifles. On 1 January 1916, the regiment was converted to Infantry along with the other units of the Canadian Mounted Rifles and Redesignated as the 1st Battalion, Canadian Mounted Rifles, CEF; after which it was assigned to the 8th Canadian Infantry Brigade, 3rd Canadian Division. The Battalion fought in France and Flanders until the end of the Great War on 11 November 1918. On 15 November 1920, the 1st Battalion, CMR was disbanded.[7]
On 15 March 1920, as a result of the Otter Commission, the regiment was redesignated as The Manitoba Mounted Rifles.[8]
During the Second World War, The Manitoba Mounted Rifles provided detachments along with the 12th Manitoba Dragoons and the 2nd Armoured Car Regiment to form the 18th (Manitoba) Reconnaissance Battalion.[9]
This active service unit would later be redesignated as the 18th (Manitoba) Armoured Car Regiment and finally as the 18th Armoured Car Regiment (12th Manitoba Dragoons)[10] where it served directly under the II Canadian Corps serving in Northwest Europe until VE Day.[11]
On 1 April 1946, The Manitoba Mounted Rifles were converted to Artillery and Amalgamated with the 37th Field Battery, RCA as the 67th Light Anti-Aircraft Regiment (Manitoba Mounted Rifles).[12]
On 12 July 1948, the regiment was transferred to Fort William, Ontario.
On 1 December 1954, the 67th Light Anti-Aircraft Regiment (Manitoba Mounted Rifles) and the 118th Medium Battery, RCA were amalgamated under the latter unit's name.
