In the Battle of Wadi Akarit on 6 April Eighth Army's infantry had to breach a formidable anti-tank obstacle. 51st (Highland) and 50th (Northumbrian) Divisions were each supported by a squadron provided by 4th CLY, which was now equipped with 29 Sherman tanks along with its 21 Crusaders. The assembly of the infantry divisions in the dark was complicated, but 51st (H) achieved its first objective easily. 50th (N) Division had a harder task, but 4th CLY's squadron was ordered round by a gap made by 51st (H) and was able to cut in behind the enemy. For the second phase 51st (H) Division's supporting infantry tanks were gradually picked off, and 4th CLY's squadron had to pass through to help out, but 50th (N) Division's squadron was able to pass its Shermans through its gap by 09.30. XXX Corps then settled down to consolidate the gap that it had made, and the enemy withdrew during the night.
