Battle of Haeju
Introduction The '''Battle of Haeju''' was a small naval battle during the main phase of the Korean War. Off Haeju Bay in the Yellow Sea, on September 10, 1950, days before the Battle of Inchon, a South Korean navy patrol boat, ''PC-703'', encountered a North Korean navy minelayer sailing vessel. After a brief fight, the North Korean minelayer was sunk with a loss of all crew and no South Korean casualties were reported. After the minelayer's sinking, ''PC-703'' discovered that the sunken vessel had laid a mine field at the mouth of the Haeju Man and then reported to base the location of the sea mines. Two days later on September 12, ''PC-703'' encountered three small transports and sank them. The three supply vessels were most likely unarmed.
