Later, in March 1942, No. 5 Commando provided a troop of demolition experts to take part in Operation Chariot, the raid on St. Nazaire. These men were attached to the force under Lieutenant Colonel Charles Newman, who was the commanding officer of No. 2 Commando, which provided the main assault force for the raid. Involving the ramming of a destroyer, into the gates of the drydock at St. Nazaire in France in order to prevent it being used as a base for the "Tirpitz", the raid was later described as the "greatest raid of all".
