On August 15, 1943, following an intensive naval bombardment, 35,000 US and Canadian troops stormed onto the Japanese owned island of Kiska. There were 17 fatalities in the ensuing fire-fight.
Things might have been worse but for the absence of the enemy.
Unperturbed by the silence that greeted them, those brave boys prowled the island for several days – skirmishing here and there and triumphantly bearing their standards aloft – all the while completely unaware the Japanese had withdrawn. By the time they realised their mistake there had been roughly 200 casualties from accidents, friendly fire, enemy booby traps and general over excitement about the whole thing. An additional 130 men suffered cases of trench foot. And all this for an island of little to no strategic or military value. Nice one.
