The action at Happo was part of a continuing pursuit of Japanese vessels dispersed from or near Okpo. Yi's 24 panokseon, 15 smaller hyeopseon, and supporting fishing craft caught and destroyed the five Japanese ships. Won Gyun had four panokseon and two additional small vessels by this point, although the latter may have been attached by Yi to supervise him rather than truly belonging to Won's command. The episode shows how local sea control became sustained pressure while disciplined fleet coordination remained a Korean command problem.
