After the Dunkirk evacuation, the Prime Minister of the United Kingdom, Winston Churchill, called for a force to be assembled and equipped to inflict casualties on the Germans and bolster British morale.
Churchill told the joint Chiefs of Staff to propose measures for an offensive against German-occupied Europe, and stated, "they must be prepared with specially trained troops of the hunter class who can develop a reign of terror down the enemy coast."
The volunteers were informed of the intended role for the commandos and that training would be "tough and demanding and any who could not measure up to the standard required would be returned to their parent unit without any leave of appeal".
The next day the unit boarded HMS Queen Emma, but on 22 February 1941, after they anchored at Scapa Flow, their real objective was divulged.

Leaving a section from A Troop to deal with them the rest of the Group ran the 1.5 miles (2.4 km) to the rear of the battery, bypassing German infantry positions on the way.
The new troop with mortar and Vickers machine gun sections provided the heavy weapons needed for their new role as assault infantry.

4 Commando were in the second wave and landed behind the initial assault battalion, from the East Yorkshire Regiment, part of the 3rd Infantry Division.
The French commander Capitaine de frégate Philippe Kieffer was just about to order an all-out assault by both troops, when reports that British amphibious tanks were in Ouistreham reached him.
Sending a guide to bring one forward, the tank arrived in front of the Casino and proceeded to destroy the German gun emplacements.
As they advanced, a tank from the 13th/18th Royal Hussars joined them, just in time to engage German snipers who had started shooting at E and F Troops.
Holding fire until the last minute, the Germans were beaten back but A Troop found themselves surrounded on three sides and forced to withdraw.
At the same time an artillery Forward Observation Officer arrived from brigade, he contacted the 25 pounder guns attached to the 6th Airborne Division and requested 12 rounds of rapid fire.
