Cap Badge - 138th (Edmonton, Alberta) Battalion, CEF The 138th Battalion, CEF, was a unit in the Canadian Expeditionary Force during the First World War. Based in Edmonton, Alberta, the unit began recruiting in late 1915 in that city. After sailing to England in August 1916, the battalion was absorbed into the 47th, 50th, 137th, and 175th Battalions, CEF, on December 8, 1916. The perpetuation of the 138th Battalion was assigned to the Edmonton Fusiliers in 1929. This regiment merged into the 19th (Alberta) Armoured Car Regiment, RCAC, in 1946. The 19th in turn merged into the South Alberta Light Horse in 2006 which now perpetuates the 138th Battalion.
