The Battle of Chumonchin Chan or the Action of 2 July 1950 was the only major battle fought between surface combatants during the main phase of the Korean War. It began after an Allied flotilla encountered a Korean People's Navy supply fleet.

On 2 July 1950, the USS Juneau, HMS Black Swan, and HMS Jamaica were sailing along the coast of the Sea of Japan (East Sea) when they encountered four North Korean torpedo and gunboats that had just finished escorting a flotilla of ten ammunition ships up the coast. The North Korean torpedo boats began an attack on the allied ships.

Before their torpedoes could be fired however, they were met with a salvo of gunfire from the United Nations ships which destroyed three of the torpedo boats. The surviving North Korean craft fled. Later in July, the Juneau encountered the same ammunition ships and destroyed them.

Propaganda mistaking a United Nations forces ship for the USS Baltimore which was never deployed to the Korean War. It also claims the heavy cruiser was sunk by North Korean torpedo boats during the battle.
