Second Battle of El Alamein. Murray was seriously wounded in the early stages of the battle and only returned to active service again in April 1943. After a brief period as temporary
General Staff Officer Grade I of the 51st Division, Murray was given command of the 153rd Infantry Brigade in the same division. After a period of rest and refit in

6th Armoured Division, after its previous commander,
Gerald Templer, was wounded. The division,
operating in Italy, was involved in the fighting on the
Gothic Line in late 1944 before being withdrawn into reserve and then joining
V Corps for the
Spring 1945 offensive in Italy. Following the breaking of the
Axis defences in the
Argenta Gap by the
56th and
78th Infantry Divisions, the 6th Armoured Division was released to exploit across country. Advancing north-west to the River Po, the division linked up with units of the
United States Fifth Army, under Lieutenant General
Lucian Truscott, advancing from the south to cut off Axis forces in Bologna. By 8 May the division was crossing the Austrian frontier becoming the first element of the
British Eighth Army, under Lieutenant General
Richard McCreery, to enter German territory. Murray was
mentioned in despatches for his services in Italy, and appointed a
Companion of the Order of the Bath in 1945. Although he held an appointment as
acting major general, Murray's permanent rank was still only major (war substantive
lieutenant colonel, temporary
brigadier) at the end of the war because of his relative youth. In August 1945 he was advanced to temporary major general, war substantive
colonel. His substantive rank was advanced to full colonel in December 1946, and again to major general in January 1948. ==Postwar career==
