The 7th Battalion was a Territorial Army (TA) unit serving in the 154th (Highland) Infantry Brigade. The brigade was part of the 51st (Highland) Infantry Division in France in 1940 as part of the British Expeditionary Force. They were stationed on the Maginot Line and so avoided being encircled with the rest of the BEF during the Battle of France. The 7th Argylls in particular suffered heavy losses during the fighting, the worst day in its history. The 154th Brigade managed to be evacuated to England after the 51st (Highland) Division was forced to surrender on 12 June 1940. The division was reconstituted by the redesignation of the 9th (Highland) Infantry Division to the 51st. The understrength 154th Brigade of the old 51st was merged with the 28th Infantry Brigade. In 1942 the new 51st Division, 7th Argylls included, were sent to join the British Eighth Army in the North African Campaign. They fought in the First Battle of El Alamein and in the Second Battle of El Alamein which turned the tide of the war in favour of the Allies. During the fighting in North Africa, Lieutenant Colonel Lorne MacLaine Campbell of 7th Argylls was awarded the Victoria Cross. In March 1942, two British privates from the 7th battalion, Macfarlane and Goldie, escaped wearing their blue work detail overalls over their battledress. They wore rucksacks to cover the markings "KG" ("Kriegsgefangener", "prisoner of war") on their backs. They secreted themselves in a rail wagon carrying salt to Belgium. There they managed to contact an escape line and, by the middle of the year, they were safely back in Scotland.
