Sacheon May 29 1592 Strategic Context After recently

Sacheon May 29, 1592 Strategic Context After recently unifying Japan under his one rule, Toyotomi Hideyoshi hopes that Korean King Seonjo will grant his armies free passage through the peninsula to invade China but is refused. Hideyoshi therefore invades Korea with 150, 000 soldiers, routing Korean forces and capturing city after city. However, the Japanese army is reliant on the navy for supplies and Korean Admiral Yi Sun-sin receives reports of Japanese ships around Sacheon, dangerously close to his headquarters at Yosu. Yi arrives in the hopes of destroying this fleet and interdicting supply to Japanese land forces.
