Regrouping was still in progress after arrival in Italy, when the 12th Motorised Brigade with artillery and support elements was ordered to move to the area of Isernia to prepare to relieve the 11th Canadian Infantry Brigade in the Cassino area and to come under command of the 2nd New Zealand Division in the British X Corps. These were the first division troops to enter combat in Italy. The South African Brigade held these positions until after the fall of Monte Cassino and the breakout from the Anzio beachhead, when they were withdrawn and reunited with the division.
