The Action of 8 June 1945, sometimes called the Sinking of the Ashigara was a naval action that resulted in the sinking of the heavy cruiser Ashigara of the Imperial Japanese Navy by the British Royal Navy submarine HMS Trenchant. Ashigara—which was being escorted by the destroyer Kamikaze—was being used to transport troops from Indonesia for the defence of Singapore and the sinking resulted in a huge loss of life.
