After careful study of potential battlefields, in October 1597 Admiral Yi lured the Japanese fleet into the Myeongnyang Strait, by sending a fast warship near the Japanese naval base and luring the Japanese fleet out of anchorage. The Japanese assumed that this was a Joseon scouting ship and that pursuing it would lead to the location of Admiral Yi, giving them an opportunity to destroy the courageous admiral and the remnants of the Joseon fleet. What they did not know was that they were being lured into a masterfully devised trap.
