History of the Unit
Many of the original members of No.3 had served with the British Expeditionary force in France and had been evacuated from Dunkirk.
Operation Chariot. St. Nazaire March 1942. No.3 supplied a detachment of demolition specialists for the raid.
Operation Jubilee. Dieppe August 1942. Heavy losses sustained. [View Dieppe ROH]. As a result of the losses at Dieppe the Commando was then rested for replenishment.
The War Diary records that in July 1943 total strength was down to just over 250 and the Troops were reorganised into HQ and four other Troops. The then 2 Troop became a Heavy Weapons Troop
Operation Overlord. One of the critical actions fought by No 3 after D-Day was at the river Orne and the capture of the Merville Battery to the flank of the landing beaches. The Battery was captured but at great loss to No 3 Commando. A brief replenishment in the UK followed at Worthing and then the unit was back in action again as part of the British Liberation Army.
At this time 233 OR's from No.4 Commando were posted to Nos. 3 and 6 Commandos, to bolster their numbers for the invasion, however Japan surrendered and the war ended.
The Commando was disbanded along with other Army Commando units in November 1945.
