1st Canadian Division


The 1st Canadian Division is a joint operational command and control formation based at CFB Kingston, and falls under Canadian Joint Operations Command. It is a high-readiness unit, able to move on very short notice, and is staffed and equipped to meet Canada's military objectives to counter any potential threat.
Formed during the First World War in August 1914, the 1st Canadian Division was a formation of the Canadian Expeditionary Force. The division contained a cavalry squadron and a cyclist company, three infantry brigades, representing all parts of Canada, three field artillery brigades armed with 18-pounders and engineers, together with elements of the Army Service Corps and the Army Medical Corps.  The total war establishment of the division was 17,873 all ranks, with 4,943 horses. During its service in the First World War, the division fought at Ypres, Festubert, the Somme, Vimy Ridge, Passchendaele and Amiens among other notable battles on the Western Front.
Following the war, the division was stood down, only to be re-mobilized as a formation on 1 September 1939 as the 1st Canadian Infantry Division for service in the Second World War. The division was part of the Allied campaign to invade Sicily, as well as their campaign on the Italian mainland, where they are associated with such notable battles as Ortona, the Liri Valley and the Gothic Line. The division reunited with the First Canadian Army in 1945 to participate in the liberation of the Western Netherlands before the end of the war in Europe.
The division was also reactivated twice during the Cold War: from 1953 to 1958, and again from 1988 to 1992.
In 2010, the division was reactivated for a third time. While the four divisions of the Canadian Army are responsible for command of units within their respective geographic regions, the 1st Canadian Division Headquarters was formed to serve as a task-tailored, deployable joint headquarters at high readiness to command and control joint, inter-agency, multinational forces to achieve national objectives at home and abroad.

First World War

The First Contingent of the Canadian Expeditionary Force was raised in August 1914, shortly after the outbreak of the Great War, concentrated at Valcartier Camp in Quebec, and set off for England in the largest trans-Atlantic convoy to date two months later. Training and reorganization commenced upon arrival in the United Kingdom in October 1914, and it was not until 26 January 1915 that the division was officially organized, under the command of Lieutenant-General Edwin Alderson, a British Army officer. Several units under command of the First Contingent were excluded from the divisional organization, including the 17th Battalion, 18th Battalion, and several companies of Newfoundland soldiers.
The division consisted originally of a cavalry squadron, cyclist company, four infantry brigades, three artillery brigades armed with 18-pounders, and divisional engineers, with supporting troops of the Canadian Army Service Corps and Canadian Army Medical Corps. The strength of the division was placed at 17,873 all ranks, with 4,943 horses. The 4th Brigade was broken up in January 1915, with one battalion going to the 2nd Brigade, and the other three battalions being used to form the Canadian Training Depot, ultimately being re-designated as "Reserve" Battalions. The 10th Battalion replaced the 6th Battalion, which left the 2nd Brigade to become a cavalry unit, later serving in the Canadian Cavalry Brigade.
Pioneer units were added later in the war, including the 1st Canadian Pioneer Battalion from March 1916 to February 1917, when they became the 9th Canadian Railway Battalion. The 107th Canadian Pioneer Battalion also came under command between March 1917 and May 1918, before being absorbed by the 1st Canadian Engineer Brigade.
Lieutenant-General Alderson was selected and appointed in October 1914 to command the new Canadian Division, as it was known at that time, making him the highest ranking divisional commander in the British Army. He was selected — to the relief of many — in lieu of Sir Sam Hughes, who was promoted at this time by the prime minister to the rank of Major-General. It had been Hughes's wish to command the Canadians in action. Alderson, who had commanded Canadian units before, won out over three prospective Canadian appointees, who, while serving with the British Army, were still considered too inexperienced. Alderson, meanwhile, had first seen action against the Boers in 1881, and thereafter fought in Egypt, the Sudan and Mashonaland. He also served throughout the South African War of 1899–1902, in which he had Canadian mounted troops under his command.
Training in the winter of 1914 was rigorous, and conditions on Salisbury Plain were harsh due to cold and rain. Alderson rejected the "shoddy" kit that was supplied from Canada including the Ross Rifle which had been adopted due to the slow rate of supply of the Lee–Enfield and which was seen as an example of Canadian nationalism. A royal inspection of the division early in 1915 foretold a move to France.
Early in 1915, it was evident that the Canadians would soon be going to France. The division paraded in drill order for an inspection by His Majesty King George V; thereafter, units boarded troop ships at Avonmouth and during mid-February, the entire division crossed the rough Channel to St. Nazaire. After a brief period in reserve near Hazebrouck, the Canadians relieved the 7th British Division in the Fleurbaix sector near Armentières on 1–3 March. General Alderson then became responsible for of front line on the left flank of the First Army.
The division moved to the Ypres Salient in April, and faced its first real test during the defence of St. Julien beginning on 22 April. The Canadians withstood German attack — aided, for the first time on the Western Front, by the use of poison gas — and finally retired to secondary positions on 26 April, where they held on until 4 May. The Second Battle of Ypres, as the overall action came to be known, cost the infantry brigades some 5,506 men.
Two weeks later, the division was in action again at Festubert. Aiding in a diversionary offensive by the British armies, the Canadians suffered 2,204 casualties for gains of only. Another futile attack was launched at Givenchy-en-Gohelle in June 1915, after which the division moved to Ploegsteert.
The Canadians began a long period of static warfare which would last them throughout the winter. In September, the arrival of the 2nd Canadian Division meant that a national corps headquarters could take to the field to command the division. Major-General Arthur Currie took command of the division in September. Active operations resumed again in the spring of 1916, participating in the Battle of Mount Sorrel, and then restoring the situation at Sanctuary Wood.
The Battle of the Somme opened on 1 July 1916, the costliest day in the history of the British Army, with over 19,000 British soldiers killed and 38,000 wounded. The Canadian part in the battle, which was to last through to November, did not begin until September at Battle of Pozières and lasted through to October. It was on the Somme that the red patch was first worn as an identifying device—two inches by three inches and worn on both sleeves, this rectangle identified the wearer as belonging to the 1st Division. The insignia was also painted on steel trench helmets, and adorned with geometric shapes of different colours to further identify the soldier's specific battery, brigade, battalion or other subunit.
The division began to prepare for the historic assault on Vimy Ridge, and took the time-honoured position of right of the line on 9 April 1917 when the corps took the ridge. Other gains were made in the days following the successful assault on the ridge, and the division participated in the battle of Hill 70 in August 1917. The Third Battle of Ypres followed in mid-October, and fighting continued into November. The division served under Major-General Archibald Cameron Macdonell beginning in May; his command persisted until Armistice Day.
Massive German offensives came in the spring of 1918, but the Canadian Corps—now considered crack assault troops—were held in reserve for the inevitable counter-offensives. "Canada's Hundred Days"—the last 100 days of the war—were marked by several Canadian successes, at Amiens, Arras, Canal du Nord and the Pursuit to Mons. The armistice of 11 November 1918 finally brought the Great War to an end.
