Operation Battle of Sagami Bay

The 'Battle of Sagami Bay' was fought between US and Japanese naval forces in the course of a US anti-shipping raid off the tip of Boso peninsula (22/23 July 1945).

This was the last surface action of World War II, and in it the US Navy’s Destroyer Squadron 61 engaged a Japanese convoy consisting of two freighters escorted by submarine chaser No. 42 and the minesweeper No. 1. In this night action, the US destroyers, under the command of Captain T. H. Hederman, sank a freighter, the 800-ton No. 5 Hakutetsu Maru and damaged another, the 6,919-ton Enbun Maru. The Japanese escorts were not damaged.
