fleet of Toyotomi Hideyoshi stationed at Busan. Over the course of the battle, Japanese forces lost 100 ships while no Korean ships were lost. Officer Woon (ko) and six Korean soldiers, as well as countless Japanese soldiers were killed. However, ultimately, the Korean fleet retreated, failing to take over Busan. In the Annals of the Joseon Dynasty (a Korean official history, written by a bureaucrat of the Korean government located in Hanyang District), it is recorded that the Korean navy failed to defeat the Japanese at Busan. However, in other primary historical sources, such as the official Joseon compendium (李忠武公全書) written by Joseon bureaucrats, and the War Diary of Yi Sun-sin and his military reports, it is recorded as a decisive Korean victory. Modern historians have also summarized the battle as a decisive Korean victory.李舜臣, 李忠武公全書, 金屬活字本(丁酉字),內閣, 正祖 19(1795) Some Korean historians believe the War Diary of Yi Sun-sin more than Annals of the Joseon Dynasty when they study the Imjin war because he was the on-scene commander.

There were three main types of Korean "righteous army" militias during the war: the surviving and leaderless Korean regular soldiers, the patriotic yangbans (aristocrats) and commoners, and Buddhist monks. By the summer of 1592, there were about 22,200 Korean guerrillas serving the Righteous Army, who tied up much of the Japanese force. During the first invasion, Jeolla Province remained the only untouched area on the Korean peninsula. In addition to the successful patrols of the sea by Yi Sun-sin, the activities of volunteer forces pressured the Japanese troops to avoid the province in favour of other priorities. Gwak Jae-u's campaigns along the Nakdong River Gwak Jae-u was a famous leader in the Korean militia movement, the first to form a resistance group against the Japanese invaders. He was a land-owner in the
