Admiral Yi Sun-sin was a Korean admiral and military general famed for his victories against the Japanese navy during the Imjin war in the Joseon Dynasty. Over the course of his career, Admiral Yi fought in at least 23 recorded naval engagements, all against the Japanese. In most of these battles, he was outnumbered and lacked necessary supplies. He nonetheless won battle after battle. His most famous victory occurred at the Battle of Myeongnyang, where despite being outnumbered 333 to 13, he managed to disable or destroy 31 Japanese warships without losing a single ship of his own. Yi died from a gunshot wound at the Battle of Noryang on 16 December 1598, the closing battle of the Imjin War.
The Japanese invasions of Korea, commonly known as the Imjin War, involved two separate yet linked invasions: an initial invasion in 1592, a brief truce in 1596, and a second invasion in 1597. The conflict ended in 1598 with the withdrawal of Japanese forces from the Korean Peninsula after a military stalemate in Korea's southern provinces.
A Geobukseon, also known as turtle ship in western descriptions, was a type of large Korean warship that was used intermittently by the Royal Korean Navy during the Joseon dynasty from the early 15th century up until the 19th century. It was used alongside the panokseon warships in the fight against invading Japanese naval ships. The ship's name derives from its protective shell-like covering. One of a number of pre-industrial armoured ships developed in Europe and in East Asia, this design has been described by some as the first armored ship in the world.
In the Battle of Myeongnyang, on October 26, 1597, the Korean Joseon Kingdom's navy, led by Admiral Yi Sun-sin, fought the Japanese navy in the Myeongnyang Strait, near Jindo Island, off the southwest corner of the Korean peninsula.
The Battle of Noryang, the last major battle of the Japanese invasions of Korea (1592–1598), was fought between the Japanese navy and the combined fleets of the Joseon Kingdom and the Ming dynasty. It took place in the early morning of 16 December 1598 and ended past dawn.
The Battle of Okpo was a military engagement which took place during the Japanese invasions of Korea (1592–98), also known as the Imjin War. Korean commanders Yi Sun-sin and Won Gyun's fleet destroyed a group of anchored Japanese transport ships. It was the first naval battle of the Imjin War, and the first victory of Admiral Yi against the Japanese naval fleet of Todo Takatora. A day later, after destroying an additional 18 Japanese transport vessels in nearby waters, Yi Sun-sin and Won Gyun parted ways and returned to their home ports after receiving news of the fall of Hanseong. The Battle of Okpo caused anxiety and nervousness among the Japanese, because afterward Yi began to deploy his navy to attack Japanese supply and carrier vessels.
The Battle of Busan of 1592 was a naval bombardment of anchored Japanese ships at Busan. Yi Sun-sin managed to destroy over 100 Japanese ships and retreated with minimal casualties. It was a naval engagement that took place on 1 September 1592 during the first phase of the Japanese invasions of Korea. It was a Korean surprise attack on the fleet of Toyotomi Hideyoshi stationed at Busan, and its main objective was to recapture Busan, which would thoroughly cutoff the supply line of the Japanese army. In this battle, officer Jung Un and six soldiers died, the Japanese lost over 100 ships, and the Japanese military lost control of the seas around the Joseon.
The Battle of Sacheon was a naval engagement on May 29, 1592 during the Imjin War (1592–98). It occurred at Sacheon where Yi Sunsin's fleet managed to destroy 13 large Japanese ships. It was the first battle of Admiral Yi's 2nd Campaign in the Imjin War, between Japan and Korea, when the turtle ship was first used.
The naval Battle of Chilcheollyang took place on the night of 28 August 1597. It resulted in the destruction of nearly the entire Korean fleet.
The Joseon naval campaigns of 1592 were naval campaigns conducted by Korean admiral Yi Sun-sin during Japanese invasions of Korea (1592-1598) against the Japanese forces of Toyotomi Hideyoshi. These campaigns made Yi a legendary figure in Korean history on par with, if not surpassing, the great general Eulji Mundeok. The campaigns of Yi were vital in halting the Japanese invasion, which had the ultimate aim of conquering not just Korea, but Ming China as well. Yi was able to severely impair Japanese logistics and reinforcements for the land forces in Korea.
The Battle of Hansan Island and following engagement at Angolpo took place from 8 July 1592. In two naval encounters, Korean Admiral Yi Sun-sin's fleet managed to destroy roughly 100 Japanese ships and halted Japanese naval operations along the southern coast.
Won Gyun was a Korean general and admiral during the Joseon Dynasty. He is best known for his campaigns against the Japanese during Hideyoshi's invasions of Korea. Won was a member of Wonju Won family, which was well known for its members' military accomplishments. He was born in 1540 near Pyeongtaek and demonstrated his skill as warrior at a young age. He was qualified as a military officer and was first assigned to the northern border to defend against the Jurchens, who frequently raided Korean villages. Won led many successful campaigns with Yi Il and Yi Sun-sin against the Jurchens. After considerable accomplishments on the northern frontier, he was promoted to admiral in 1592 and sent to the southern coast of Gyeongsang Province to command the province's Western Fleet, along with Yi Sun-sin, who became admiral before Won and took command of Jeolla Province's Eastern Fleet. At the time, Won and Yi were cavalry leaders who had no experience with naval warfare.
The Battle of Jeokjinpo was fought on 8 May 1592. After the Battle of Happo, further reports of an additional 13 Japanese ships prevented Yi Sun-sin and his fleet from resting long on the morning of 8 May. Admiral Yi once again ordered his fleet to pursue the Japanese in the direction of Jinhae. The Korean forces caught up with the Japanese ships at Jeokjinpo. The Koreans easily sank 11 Japanese warships.
