During the Second World War, the brigade served with the division during Operation Ariel in 1940 in France to cover the withdrawal of troops of the British Expeditionary Force (BEF) which was being evacuated from France. From May 1942 to June 1944 the division was trained in mountain warfare yet were never used in the role. They were then trained in airlanding operations but were again never utilised in this role either, due mainly to the disastrous events that occurred during the Battle of Arnhem where the British 1st Airborne Division was virtually destroyed. In October 1944 the 52nd Division was sent to the Western Front to join the 21st Army Group and were attached to the First Canadian Army and fought in the Battle of the Scheldt where the 52nd Division gained an excellent reputation. The 156th Infantry Brigade, with the 52nd, took part in Operation Blackcock in early 1945, later taking part in the Western Allied invasion of Germany, and ended the war by the River Elbe. During Blackcock, Fusilier Dennis Donnini of the 4th/5th Battalion, Royal Scots Fusiliers was posthumously awarded the Victoria Cross. At the age of 19, he was the youngest British or Commonwealth soldier to be awarded the VC during the Second World War.
