Admiral Yi Sun-sin's Leadership Amid Illness.

Admiral Yi Sun-sin's War Diary from April 22 to 29, 1594

Annotation
Admiral Yi Sun-sin's illness in April 1594 was likely caused by overwork, extreme stress, poor nutrition, and unsanitary conditions. During the war, his heavy workload and mental pressure may have weakened his immune system, making him more vulnerable to illness. Symptoms such as pain, fever, and exhaustion suggest the possibility of an infectious disease, acute inflammation, or nerve pain caused by fatigue.
Despite days of severe suffering, Admiral Yi recovered and resumed his duties, showing his strong willpower and sense of responsibility. With limited medical support at the time, natural recovery and his determination likely played a major role in his healing. This record not only reflects his health challenges but also highlights his dedication to serving his country during the Imjin War.
