Bak Jin

Bak Jin (, 25 August 1560 – March 1597), also known as Park Jin, was a Korean Joseon Dynasty Army general and politician. He was one of the Korean generals of the Imjin War.

Battle of Kyongju
During the Imjin War, Bak Jin fought to recapture the city of Kyongju from the Japanese invaders. His first attack was repelled, but he returned with a mortar and fired a delayed-action bomb over the wall. The Japanese evacuated the city rather than defend it against such mortars.
