Yangtse Incident: The Story of H.M.S. Amethyst

This film, based on real historical events, follows the British frigate H.M.S. Amethyst, which, on a mission to resupply the British Embassy during the Chinese Civil War, was unexpectedly attacked by the Chinese People's Liberation Army on the north bank of the Yangtse river. With rescue attempts blocked by the Chinese communist army, for many weeks the situation remained in deadlock, until finally, Lieutenant-Commander John S. Kerans realized he must make a dangerous decision: trust their captors to release them, or run the gauntlet of communist batteries down 140 miles of hostile territory.
