My dad used to kid about how "Safe" he felt after it was declared secure and the Marines left. After all, he was there with them for three weeks or so during the invasion, and that was awful enough. Problem was, the Japs kept trying to kill him just as much after the Island was secure. He laughed about the idea of a "rear area" on Iwo, as they were regularly attacked, sniped, shelled, and bombed for months. He said he guess someone forgot to tell the Japs that the island was secure, and headquarters was supposed to be safe! The last Japanesesoldiers will killed in action in late August, if I recall from the record in the book.
