Your dad fought at Attu, which during WW2 was the only land battle fought within the United States proper and the only battle fought in winter conditions between the Americans and Japanese? (The Alaska Territory was an incorporated territory at the time, so it was part of the United States proper and not an overseas colony. It was at the time as much a part of the United States as the Colorado Territory and the Dakota Territory were in their time.)
