By 4:00pm on August 15, a total of 6,500 troops were on the ground on the west side of Kiska. The Canadian contingent came ashore on the north side of the island the next day. However, the invasion was an embarrassment for the Allied forces. The island of Kiska was, in fact, uninhabited - the entire Japanese force of 5,183 men had left the island on July 28 without the Americans noticing. However, the Americans suffered significant casualties during their 'invasion' - 313 men died as a result of accidents, with many dying due to accidental fire. Of the total 313 dead, 70 died when the destroyer USS Abner Read struck a mine, while at least 21 died due to friendly fire. The Japanese had completely deserted their buildings on the island, leaving behind them scrawled messages on the walls for the Allied troops to read - most attacked President of the United States Franklin Roosevelt and Prime Minister of the United Kingdom Winston Churchill; for example, one of the messages read, in a mixture of English and German, You are dancing by foolische order of Rousebelt [sic].
