Kiska Island, that frozen volcanic outcrop at the edge of the Bering Sea, had been Japanese-occupied territory for exactly one year. Aerial reconnaissance showed fortifications, gun emplacements, and what appeared to be a garrison of perhaps 10,000 enemy soldiers dug into the tundra.

For weeks, the most intensive bombing campaign of the Aleutian theater had pounded the island. Navy warships hurled shells into the fog. B-24 Liberators dropped their payloads through gaps in the eternal overcast. The Japanese, it seemed, were simply enduring the onslaught, waiting.
