The 2nd Battalion was sent to France in 1940 with the 132nd Infantry Brigade attached to the 44th (Home Counties) Infantry Division to join the British Expeditionary Force and fought in the short but fierce Battle of Dunkirk, after which it was evacuated back to Britain. The 44th Division was sent to fight in the North African Campaign, where it was broken up due to an apparently poor performance in the Battle of Alam el Halfa despite the division having just the 132nd Brigade under command as other brigades had been detached to other divisions. The 132nd Brigade disbanded and 2nd Buffs was then transferred to the Far East with the 26th Indian Infantry Brigade and remained there for the war. In 1944, the brigade was redesignated the 26th British Infantry Brigade, which itself became part of the 36th British Infantry Division and served with the British Fourteenth Army in the Burma Campaign.
