On 1 October 1954, two historic Canadian Militia infantry regiments ‒ The Oxford Rifles and The Canadian Fusiliers (City of London Regiment) (MG) ‒ were amalgamated to form “The London and Oxford Fusiliers (3rd Battalion, The Royal Canadian Regiment). The unit’s title subsequently changed on 25 April 1958 to become “3rd Battalion, The RCR (London and Oxford Fusiliers) and again in 1965 to simply “3rd Battalion, The Royal Canadian Regiment.” On 22 May 1970, on the creation of a new 3rd Battalion of the regiment embodied in the Regular Force, the battalion designation evolved to its present designation as the 4th Battalion. Through the incorporation of the 4th Battalion, The RCR gained the perpetuations of both the Oxford Rifles whose origins date from 14 August 1863, as well as the Canadian Fusiliers (City of London Regiment) (MG) which originated on 27 April 1866. Both the Oxford Rifles and the Canadian Fusiliers contributed soldiers to fight in the Fenian Raids (1866-1871), the Northwest Rebellion (1885), and the South African (Boer) War (1900) (in the 2nd (Special Service) Battalion), while also making historic contributions to the 1st Battalion CEF, 2nd Battalion (MG), 33rd Battalion, 142nd Battalion and the 168th Battalions of the Canadian Expeditionary Force (CEF) in World War I. Indeed the regiment’s three battle honours from the War of 1812 are perpetuated from the incorporation of the Oxford Rifles and the Canadian Fusiliers’ geographical antecedents, while nine of The RCR’s World War I battle honours are the result of the regiment’s perpetuation of the 1st Battalion, CEF.
62 years after their amalgamation with The RCR, 153 years after the creation of the perpetuated regiments and 204 years after the original geographically-perpetuated regiments fought in the War of 1812, the 4th Battalion today is a Primary Reserve infantry unit of keen, fit and knowledgeable soldiers whose members occupy positions in all walks of civil society. From policemen, firemen, nurses and lawyers to university students, industrial workers, bankers and investment brokers, the members of the 4th Battalion are truly, in the famous phrase attributed to Sir Winston Churchill, “twice the citizen”. Since the move of the 1st Battalion to Victoria Barracks, Petawawa in 1992, the 4th Battalion has occupied the historic home of the regiment – Wolseley Barracks in London, Ontario, with a detached company in Stratford, Ontario. Built in 1883, Wolseley Barracks is a national historic building, being the first purpose-built Defence structure executed by the Dominion Government as well as the birthplace of both the Royal Canadian Infantry Corps and The Royal Canadian Regiment.
