Sergeant Stewart Deery, No.12 Commando, was awarded the Military Medal for gallant and distinguished service during Operation Chariot at St Nazaire. He had embarked on HMS Campbeltown for the raid and was taken prisoner of war afterwards [1][a][1b][2][2a]. 

Sgt. Deery was in a demolition party commanded by Lt. Brett whose task was to destroy the Dry Dock installations. Before these were able to be carried out Lt. Brett was wounded and Sgt Deery took over command of the party. Under continuous heavy fire he proceeded to carry out the demolitions successfully. When his task was completed Sgt. Deery assisted his wounded officer under heavy fire back to the point of embarkation. His courage and devotion to duty were a fine example [1a].
