Battle of Okpo - Aftermath

Aftermath

Yi was promoted to Naval Commander of the Three Provinces (Hangul : 삼도수군통제사, Hanja : 三道水軍統制使) by King Seonjo, a position equivalent to the modern admiral, which gave him authority over the Jeolla Right and Left Navies, the Gyeongsang Right and Left Navies, and the Chungcheong Navy. Yi's view of the Japanese slaughtering and looting local towns made him very determined to protect the Korean people by preventing the Japanese ships from even landing on shore. Later, at the Battle of Sacheon, he first used his "secret weapon", the Turtle Ships and defeated the Japanese again.
