The 7th Battalion, Royal Norfolk Regiment was formed in May 1939 as a 2nd Line Territorial Army duplicate of the 5th Battalion and, therefore, contained many former members of the 5th. Together with the 5th and 6th battalions, the 7th was assigned to the 53rd Infantry Brigade, part of the 18th Infantry Division until November when it assigned to pioneer duties in France with the British Expeditionary Force (BEF). In May 1940, it was assigned to the 51st (Highland) Infantry Division. The 51st Division was stationed on the Maginot Line and therefore escaped encirclement with the rest of the BEF during the Battle of France where they spent some time attached to the French Tenth Army. The 7th Royal Norfolks suffered heavy casualties when the 51st (Highland) Infantry Division was surrounded and had no choice but to surrender, on 12 June 1940, with only 31 members of the battalion managing to return to Britain. In October 1940 the battalion was assigned to 205th Independent Infantry Brigade (Home), then the 220th Independent Infantry Brigade (Home). On 14 October 1942, the battalion was transferred to the 176th Infantry Brigade, alongside the 7th Battalion, South Staffordshire Regiment and 6th Battalion, North Staffordshire Regiment, of the 59th (Staffordshire) Infantry Division. The 59th Division was one of the follow-up units after D-Day in June 1944 and was considered by General Bernard Montgomery as one of his best divisions. On the night of 7/8 August 1944, Captain David Auldjo Jamieson of D Company was awarded the Victoria Cross for his heroic leadership which greatly helped to fend off several enemy counter-attacks in a 36-hour period. Due to an acute shortage of infantrymen in the British Army at the time, the battalion and division were disbanded in late August 1944 and its men used as replacements for other British divisions in the 21st Army Group who had also suffered heavy casualties in Normandy.
