In the later stages of the battle elements of the division were switched north to assist the main breakthrough.  44th (HC) Division was broken up after Alamein and 57th Fd Rgt became an Army Field Regiment under Eighth Army. In January 1943 it joined 5th Army Group Royal Artillery (5 AGRA) forming at Medenine in Tunisia. 5 AGRA usually supported XXX Corps. The regiment participated in the battles of Medenine, Mareth, Wadi Akarit, and the capture of Tunis.  57th Field Rgt took part in the Allied invasion of Sicily (Operation Husky) as part of 5 AGRA supporting XXX Corps' campaign in the east of the island. On 2 August the regiment supported the successful attack by 38th (Irish) Brigade on Centuripe. 5 AGRA and the rest of XXX Corps artillery then provided crushing support for XIII Corps in its assault crossing of the Straits of Messina (Operation Baytown) on 3 September 1943. Against this force, the landings were not seriously disputed, and Eighth Army began advancing up the Calabria coast. In November, XXX Corps including HQ 5 AGRA were withdrawn to the UK to prepare for the Allied invasion of Europe (Operation Overlord), and 57th Fd Rgt transferred to 6 AGRA, which remained under Eighth Army in Italy.  6 AGRA supported V Corps at the crossing on the Sangro in November 1943, when 57th Fd Rgt was detached to work directly under 78th Division. The field regiments fired over 600 rounds per gun in the three days of this engagement. 6 AGRA was involved in other operations by Eighth Army and US Fifth Army, including the Battle of Monte Cassino in April 1944, the fighting on the Gothic Line (August) and at Castel del Rio (December 1944), and the crossing of the River Po (April 1945) that effectively ended the Italian Campaign.  57th (Home Counties) Field Regiment was placed in suspended animation in 1946.  113th Field Regiment mobilised in 12th (Eastern) Division, the 2nd Line duplicate of 44th (HC) Division, but when the division moved to France in April 1940 it was only intended for labour duties and the RA units remained behind in the UK. After the Dunkirk evacuation the 12th Division was broken up, and on 6 July 113th Fd Rgt joined 1st London Division (shortly afterwards designated 56th (London) Division). Post-Dunkirk, this formation was part of XII Corps in the south-east corner of England, the most-threatened area in the country, moving to XI Corps in November.
