The Welsh Guards were increased to three battalions during the Second World War. The 1st Battalion fought valiantly in all the campaigns of the North-West European Theatre. The 2nd Battalion, part of the 20th Independent Infantry Brigade (Guards), fought briefly in Boulogne, France, in late May 1940 whilst the 1st fought in the battles of Belgium and France as part of the British Expeditionary Force (BEF) GHQ Troops. In May 1940 at the Battle of Arras, the Welsh Guards gained their second Victoria Cross by Lieutenant Christopher Furness, who was subsequently killed in action. The 1st Battalion was subsequently part of the retreat to Dunkirk, where they were involved in the legendary Dunkirk evacuation that saw nearly 340,000 Allied troops return to the United Kingdom, against all odds.
