Not sure where that information came from. The 65th Carabiniers Mont Royal were re-designated Les Fusiliers Mont-Royal in 1920. As such they served as an infantry battalion in 2 Canadian Division during the Second World War. Anti-aircraft Searchlight Batteries were short lived, from the start of the war until about the middle of 1942. They were Royal Canadian Artillery units.
Perhaps Association Ancien Soldats ?
