After the Japanese attack on Pearl Harbour in December 1941, Japanese Americans were put in a terrible position in the USA. Many tens of thousands of Japanese Americans were interned in cruel conditions being classified as enemy aliens and held in suspicion of being agents for Japan. Despite this many thousands of young men, mostly second-generation Japanese Americans volunteered for service in the American Military. They served in all branches of the US military but the 442nd Infantry Regiment was formed almost exclusively from men of Japanese descent. This unit fought with distinction in Europe in the late stages of the Second World War and is the most highly decorated military unit of its size in American military history. Daniel James Brown is today's podcast guest and he has recently authored Facing The Mountain: The Forgotten Heroes of World War II all about this oft-forgotten aspect of the conflict. He and Dan discuss how the 422nd came into being, the experiences of some of the men of the unit, the prejudice faced by its soldiers, and the legacy of the Purple Heart Battalion.
