Messervy knew little about tanks and was not considered a great success commanding armoured divisions by his superiors. He was dismissed from command of 7th Armoured Division by Eighth Army commander Neil Ritchie in late June 1942 following the severe defeat the division had sustained at the Battle of Gazala. He transferred to Cairo as Deputy Chief of General Staff, GHQ Middle East Command 1942 and was sent to India a few months later to raise 43rd Indian Armoured Division as its commander.
