On the 6th of June 1942 Japanese troops invaded the island of Attu which is part of Alaska, it was the first time since 1812 that continental America had been invaded.

In this episode we're looking at the US attack to recapture the island, the fighting was bitter in a very hostile environment, and the discovery of a diary of a Japanese army surgeon who had been trained before the war in the USA.

I'm joined by Mark Obmascik, author of The Storm on our Shoreswhich traces the story of the fighting on Attu, Paul Nobuo Tatsuguchi and an American GI called Dick Laird.
