The 2nd Canadian Division, an infantry division of the Canadian Army, was mobilized for war service on 1September 1939 at the outset of World War II. Adopting the designation of the 2nd Canadian Division, it was initially composed of volunteers within brigades established along regional lines, though a halt in recruitment in the early months of the war caused a delay in the formation of brigade and divisional headquarters. With questions concerning overseas deployment resolved, the division's respective commands were formed in May and June 1940, and at British Prime Minister Winston Churchill's request, the division was deployed to the United Kingdom between 1August and 25December 1940, forming part of the Canadian Corps.
Having performed well in training exercises during 1941 and early 1942, elements of the 2nd Division were selected as the main force for Operation Jubilee, a large-scale amphibious raid on the port of Dieppe in German-occupied France. On 19August 1942, with air and naval gunfire support, the division's 4th and 6th Infantry Brigades assaulted Dieppe's beaches. The Germans were well prepared and, despite being reinforced, the Canadians sustained heavy losses and had to be evacuated, with fewer than half their number returning to the United Kingdom.
Following a period of reconstruction and retraining from 1942 to 1944, the division joined II Canadian Corps as part of the British Second Army for the Allied invasion of Normandy. The division was redesignated as 2nd Canadian Infantry Division in January 1943. The 2nd Division saw significant action from 20July to 21August in the battles for Caen and Falaise. Joining the newly activated headquarters of the First Canadian Army in the assault on northwestern Europe, the 2nd Canadian Infantry Division played a significant role in the retaking of the Channel Ports, the Battle of the Scheldt, and the liberation of the Netherlands. The division was deactivated shortly after the end of the war.
Formation, garrison duties and organization (1939–1940)
At the start of the Second World War, the Canadian Active Service Force (CASF) was initially composed of two divisions; the 1st and 2nd Canadian Infantry Divisions, both raised on 1September 1939. The fighting power of this force lay in its constituent infantry brigades, of which each division had three. These were in turn composed of three rifle and one machine gun battalion, with additional divisional artillery and engineer units in support.
Formed under the command of Major-General Victor Odlum with an authorized strength of between 13,000 and 17,000 personnel, the 2nd Canadian Infantry Division, like its sister formation, was originally organized along regional lines. Its 4th Brigade was composed of regiments from Ontario, the 5th Brigade of regiments from Quebec, and 6th Brigade of regiments from Western Canada. These were the same infantry brigades—although their constituent battalions were different—that had formed part of the 2nd Canadian Division during its service on the Western Front as part of the Canadian Expeditionary Force during the First World War.
It was over a year before the 2nd Division came together as a cohesive unit and, during the interim period between formation and arrival in the United Kingdom, many changes to its organization were made. The first brigade concentrations took place in May and June 1940, until which time all units had trained in their own garrisons. The 4th Brigade assembled at Camp Borden in Ontario, the 5th at Valcartier Camp in Quebec, and the 6th at Camp Shilo in Manitoba. The divisional artillery was concentrated at artillery training centres at Camp Petawawa in Ontario, and at Shilo.
The 2nd Division's structure was altered in early 1940, reducing its number of machine-gun battalions from three to one. The Camerons and the Chaudières (now a rifle battalion) were reassigned to the newly mobilized 3rd Canadian Infantry Division, and the Winnipeg Grenadiers were sent to Jamaica for garrison duty, after which they returned to Canada then redeployed to Hong Kong, where they were captured when it fell to the Japanese on 25December 1941.
In May 1940, The Black Watch were moved from Valcartier to Newfoundland, and in June, the 2nd Division was earmarked for garrison duty by the forces of the British Commonwealth, with the Royal Regiment of Canada and Les Fusiliers Mont Royal arriving in Iceland later that month. However, at the request of Winston Churchill these deployments were cut short, as the division was badly needed in England to supplement the British Army—then facing the imminent possibility of German invasion.
