The 151st Battalion, Canadian Expeditionary Force (CEF), was formed during the First World War as part of Canada’s contribution to the Allied war effort. Raised in 1915 in the province of Alberta, the unit recruited men from the region and trained extensively before embarking for England in October 1916. Upon arrival, the 151st Battalion was absorbed into the 9th Reserve Battalion to provide reinforcements for Canadian units already fighting on the Western Front. Although the battalion itself did not see combat as a distinct unit, its members served with distinction in various Canadian infantry battalions throughout the remainder of the war.
