Vian's aggressive approach to the Malta fight

Keith Vian's memoir explains the central Mediterranean problem: convoys had to cross waters where the enemy could combine air power with superior surface forces. Malta remained essential because it threatened Rommel's supply line, yet keeping the island active required escorts to operate under Axis air superiority. The Dido-class cruisers' dual-purpose guns could engage ships or aircraft but not both at once, while small destroyers carried too little ammunition for prolonged air battles. Ordered merely to sight Derna, Vian reasoned that his cruiser would be detected regardless and chose to bombard the port first. Action This Day is an apt title for a commander who turned unavoidable exposure into offensive action.
