[1][2][3][4] On 11 October 1867, the 58th Compton Battalion of Infantry was authorized.
The regiment had companies at Bury (Robinson), Gould, Winslow (Stornaway), Marbleton, Lake Megantic, Compton, Coaticook and Stanstead.
[1][3] On 1 May 1903, the 58th Compton Regiment was converted from infantry to cavalry and redesignated as the 7th Hussars.
[1][3] With the outbreak of the First World War, the 7th Hussars along with the 11th Hussars provided volunteers to help raise the 5th Canadian Mounted Rifles for service with the Canadian Expeditionary Force.
However, at the same time as the 1936 amalgamation, the perpetuation of the 5th Canadian Mounted Rifles Battalion, CEF, was transferred from the Eastern Townships Mounted Rifles to the 7th/11th Hussars, which thus acquired several battle honours through the perpetuation.
