HMS Campbeltown as a destroyer-sized torpedo

A viewer describes HMS Campbeltown as the largest torpedo used in combat: a named destroyer converted into a one-off explosive weapon with roughly four and a half short tons of Amatol. The comparison is accepted. A follow-up praises the St Nazaire Raid despite mistakes in its planning and calls attention to the Victoria Crosses awarded for the operation. Campbeltown remained a warship, but her hull delivered the destructive charge like an enormous torpedo.
