Placed under the leadership of Brigadier-General Frederic William Hill,[1] it initially consisted of the 43rd, 52nd, 58th and 60th Battalions, which came respectively from Winnipeg, Port Arthur, the Niagara area and Montreal.

[3] The different battalions were then attached to other Canadian brigades already in the line, near Locre and Dranoutre, for trench familiarisation and training.

[6] Then, on June 2, the Germans launched an attack, in an attempt to divert Allied resources from the upcoming offensive in the Somme region and to gain a tactical advantage in the Ypres salient by capturing the only part of the Ypres ridge that was still in British hands.

[11] From the 4th through to the 10th, no significant action happened except for repeated shelling and a German attack by about 100 men in the evening of the 4th on positions held by the 43rd battalion, which was repulsed.

[9] On the night of the 12 and 13th, the Brigade's 58th Battalion participated in a counter-attack, in conjunction with other forces from the Canadian Corps, to attempt to recapture lost positions on the heights of Mont Sorrel and Tor Top.
