68th Medium Rgt was ordered into Tobruk where it dug in and wired up its OPs. During the lull following Crusader, 233 and 234 Btys were on the Gazala Line, running out sniping guns or patrolling Troops during the hours of darkness to fire on known enemy positions, but enemy CB fire was accurate and the gun positions came under frequent air attack. 233 Battery finally replaced its old 6-inch howitzers with US 155mm guns, also of World War I vintage, but with more range. On 29 March Lt-Col Dimoline was promoted to become Commander Royal Artillery (CRA) for 4th Indian Division and was succeeded as CO by Lt-Col P.J.H. Tuck.
