The First Canadian Division was moved by busses to Couturelle area, embussing at about midnight, March 27, 1918. At dawn, March 28, 1918, the enemy struck heavily astride the river Scarpe, and the First Canadian Division was ordered at 10.30 a. m. to retain the busses by which they had moved south and to move back to the Arras-Bainville area at once, coming there under orders of the Seventeenth Corps. This move was very difficult, because some busses had already been sent back to the Park, many units were still en route to the Couturelle area, and the mounted units and transport were in column on the road Hauteville-Saulty-Couturelle. The division, however, extricated itself, and on the night of the 28th, under orders of the Seventeenth Corps, placed two battalions in the forward area in support of the Forty-sixth Infantry Brigade, Fifteenth Division. At daybreak on the 29th the Third Canadian Infantry Brigade moved to support the Fifteenth Division, and during the night of the 29th and 30th the First Canadian Brigade relieved the Forty-sixth Infantry Brigade in the Telegraph Hill sector, that brigade front being transferred from the Fifteenth Division to the First Canadian Division on March 30, 1918. The Second Canadian Division passed under orders of the Sixth Corps on March 28, 1918, and moved forward in support of the Third British Division in the Neuville-Vitasse sector. On the night of March 29-30, 1918, it relieved the Third British Division in the line, and on the night of March 31-April 1, 1918, extended its front southward by relieving the left battalion of the Guards Division. The front held by the Second Canadian Division extended from south of the Cojeul River, east of Boisleux St.-Marc, to the southern slopes of Telegraph Hill (where it joined with the First Canadian Division), a total length of about 6,000 yards. The Second Canadian Division held this front for an uninterrupted period of ninety-two days, during which time it repulsed a series of local attacks and carried out no less than 27 raids, capturing 3 officers, 101 other ranks, 22 machine guns, 2 trench mortars, and inflicting severe casualties on the enemy. The aggressive attitude adopted by this division at such a critical time and under adverse conditions had a most excellent effect and it certainly reduced to the lowest point the fighting value of two German divisions, namely, the Twenty-sixth Reserve Division and the One Hundred and Eighty-fifth Division. The Second Canadian Division returned under the orders of the Canadian corps on July 1, 1918. The Third Canadian Division had been attached on March 27, 1918, to the Thirteenth Corps. Thus, under pressure of circumstances, the unity of command of the Canadian divisions had been destroyed. They were now attached to two different armies (First and Third) and under command of three different corps (Sixth, Seventeenth, and Thirteenth).
