This incident occurred on 30 August 1945. The scene was the largest of three forts on Futtsu Saki, a peninsula protruding into Tokyo Bay, opposite Yokosuka. The 2nd Battalion of the 4th Marines had landed there to demobilize coast defense rifles so that the Third Fleet might enter Tokyo Bay safely to carry out the main landing at Yokosuka. In the distance appears the outer fort at the end of the peninsula and further, Mount Fuji.
