During the division's period of re-fitting and training in North Africa Galloway's rank of major-general was made substantive in December 1943 and then in March 1944 he had an interlude in Italy when the commander of 4th Indian Infantry Division, which was in the front line at Cassino fell ill. Galloway arrived to take temporary command on 8 March 1944, in time for the Third Battle of Monte Cassino. In ten days of desperate fighting the Germans succeeded in holding the Allied attack and by 25 March the effort was called off. Galloway's division had to be withdrawn, having sustained some 3,000 casualties during its time at Cassino, and Galloway returned to 1st Armoured Division.
