The 1st Tank Brigade moved to the United Kingdom in the summer of 1941; personnel arrived in the Clyde on 30 June and were promptly moved to Salisbury Plain where they were issued sufficient Churchill tanks for training. The Calgary Regiment participated in the disastrous Dieppe landing in 1942. Issued brand new M4 Sherman tanks, the entire brigade moved to the Mediterranean, with The Three Rivers Regiment participating in the assault landing at Pachino. The remainder of the brigade landed with the follow-up convoy of 13 July and served alongside the Three Rivers Regiment for the final weeks of the brief campaign in Sicily. The 1st Tank Brigade's role in the latter operations was largely one of fire support, the rugged terrain limiting the role of the armoured corps. The fight for Sicily ended with 1st Tank in reserve. Preparing for Operation Baytown, the landings on mainland Italy, it was redesignated 1st Canadian Armoured Brigade in August 1943. Although reorganized as an armoured brigade, no motor battalion served under command. Having established a reputation for both courage and skill, the Canadian tankers were in constant demand by senior British commanders.
