First Canadian Army

The First Canadian Army (1reArmée canadienne) was a field army and a formation of the Canadian Army in World War II in which most Canadian elements serving in North-West Europe were assigned. It served on the Western Front from July 1944 until May 1945.

The army was formed in early 1942, replacing the existing unnumbered Canadian Corps, as the growing contribution of Canadian forces to serve with the British Army in the United Kingdom necessitated an expansion to two corps. By the end of 1943 Canadian formations consisted of three infantry divisions, two armoured divisions and two independent armoured brigades. The first commander was Lieutenant-General A. G. L. "Andy" McNaughton, who was replaced in 1944 by General H. D. G. "Harry" Crerar. Both had been senior Royal Regiment of Canadian Artillery officers in the Canadian Corps in World War I. Allied formations of other nationalities were added to the First Canadian Army to keep it at full strength.

The First Canadian Army's strength was 177,000 all ranks at the end of 1942. One year later it had grown to 242,000. On 31 May 1944, shortly before the Normandy landings, Canadian troops in Europe numbered 251,000 of which 75,000 had left First Canadian Army to serve on the Italian Front.

History


When the First Canadian Army was formed overseas in 1942, Lieutenant-General Andrew McNaughton's aim was to keep Canada's contributions to the British Army together to lead the cross-channel assault on northwest Europe. Two brigades of the 2nd Canadian Division led the ill-fated Dieppe Raid in 1942. Aside from this endeavour, the Army did not see combat until July 1943. In 1943, because the Canadian government wanted Canadian troops to see action immediately, the 1st Canadian Infantry Division, 1st Canadian Armoured Brigade, and 5th Canadian Armoured Division were detached from the Army for participation in the Italian Campaign.

In early 1944, the 3rd Canadian Infantry Division and 2nd Canadian Armoured Brigade were also detached to British I Corps to participate in the assault phase of the Normandy landings. II Canadian Corps became operational in Normandy in early July 1944, as the 2nd Canadian Infantry Division landed. The First Canadian Army headquarters did not itself arrive in Normandy until mid-July, becoming operational on 23 July 1944 just before 4th Canadian Armoured Division arriving on the Continent.



During Operation Overlord, the First Canadian Army was under the control of the British 21st Army Group. The Army proper first went into action in the Battle of Normandy and conducted operations at Falaise (e.g. Operation Totalize, Operation Tractable) and helping close the Falaise pocket. After reaching the Seine, the objective of the first phase of Operation Overlord, the Army moved along the coast towards Belgium, with the Canadian 2nd Division entering Dieppe at the beginning of September. The First Army, under acting command of Lieutenant-General Guy Simonds (from 28 September 1944 to 7 November 1944), fought the critical Battle of the Scheldt along with the supporting Operation Pheasant in October and early November, opening Antwerp for Allied shipping.

The First Canadian Army held a static line along the river Meuse (Maas) from December through February, then launched Operation Veritable in early February. By this point, the Army, besides the II Canadian Corps, contained nine British divisions. The Siegfried Line was broken and the Army reached the banks of the Rhine in early March.

In the final weeks of the war in Europe, the First Army cleared the Netherlands of German forces. By this time the First Division and Fifth (Armoured) Division as well as First Armoured Brigade and the 1st Cdn AGRA had returned to the Army during Operation Goldflake and for the first time, both the I Canadian Corps and II Canadian Corps fought under the same Army commander.

Makeup
The First Canadian Army was international in character. The size of Canada's military contribution on its own would likely not have justified the creation of a separate army-level command in North-West Europe, especially over the period when I Canadian Corps was away gaining valuable combat experience in Italy. However, both McNaughton and Crerar, backed up by the Canadian government, were successful in their lobbying for the British Army to create a Canadian-led army enlarged with contributions from other Allied countries. In addition to II Canadian Corps (which included the Canadian formations under command described above), other formations under command included the British I Corps, and the 1st Polish Armoured Division, as well as, at various times, the American 104th Infantry Division (Timberwolf), 1st Belgian Infantry Brigade, Royal Netherlands Motorized Infantry Brigade and 1st Czechoslovak Armoured Brigade. The First Canadian Army in North-West Europe during the final phases of the war comprised the largest field army ever under the control of a Canadian general. Ration strength of the army ranged from approximately 105,000 to 175,000 Canadian soldiers to anywhere from 200,000 to over 450,000 when including the soldiers from other nations.

The 'Maple Leaf Route' was the designation of the army's main supply route. The route was usually divided into Maple Leaf Up and Maple Leaf Down, designating traffic to and away from the front, respectively.
