During the period of WWI, the 8th Hussars did not muster as a regiment for service overseas. For controversial reasons, many militia cavalry units were not called for service in 1914. However in 1915, some members of the Regiment, formed a squadron with eight officers and three troops, as part of a Maritime Provinces cavalry unit known as the 6th Canadian Mounted Rifles. Their new regiment mustered at Amherst, NS, in March, 1915, to prepare for service overseas. The 6th CMR was disbanded in 1916, after three months at the front. Many members of the Regiment joined other units early on in the war tired of waiting for the call to muster the 8th Hussars. The 104th Battalion, for instance, become home to many former cavalry soldiers.
