26 ships The Battle of Dangpo (Korean: 당포 해전; Hanja: 唐浦海戰) was a naval engagement during the Japanese invasions of Korea (1592–1598) on 10 July that resulted in Yi Sun-sin's victory.

[1] The day after the Battle of Sacheon, Admiral Yi Sun-shin had his fleet rest in the open sea off Saryang where they would have the tactical advantage were the Japanese to execute a counterattack.

Admiral Yi once again summoned his resting fleet to arms the morning of July 10 (lunar June 2) when he received a report that 21 Japanese ships were docked at the harbor of Dangpo.

The battle would not continue on this day, however, as the Japanese ships made a hasty retreat into the descending darkness upon seeing the intimidating Korean fleet.

Admiral Yi then set out and searched the surrounding islands until he received a report from fishermen that another small fleet of Japanese ships lay anchored at Danghangpo, which was to be the site of another battle.
