Official Caption: "Rome, 6/1/45--U.S. troops advance on Okinawa--U.S. Marines ride atop a tank toward southern Okinawa, on their way to capture Naha, the island's capital. By May 30, 1945, they entered the ancient Shuri Castle, strongpoint in the Okinawa battle line, in such a swift strike the Japanese defenders were caught relaxing in the cool water of a moat. While some Marine patrols penetrated the fortress, other Marines overran virtually the entire city of Naha.
