Yi Sun-sin kept this diary from the first month of 1592 until the eleventh month of 1598, just before the Battle of Noryang. He wrote plainly of battles and weather, drills and supplies, his men and the common people, his longing for his mother and family, and even his quarrels with Won Gyun. The name "Nanjung ilgi" (Diary in the Midst of War) was given when the Complete Works of Yi Sun-sin were compiled under King Jeongjo.
The seven autograph volumes, together with his letters and the Imjin jangcho (copies of his reports to the court), are a National Treasure kept at Hyeonchungsa in Asan. Written by a commander in the field, it is a key source for the Imjin War and became UNESCO Memory of the World in 2013.
