At the outbreak of the Korean War, Puller was once again assigned as commander of the First Marine Regiment. He participated in the landing at Inchon on September 15, 1950, and was awarded the Silver Star Medal. For leadership from September 15 through November 2, he was awarded his second Legion of Merit. He was awarded the Distinguished Service Cross from the U.S. Army for heroism in action from November 29 to December 4, and his fifth Navy Cross for heroism during December 5–10, 1950, at the Battle of Chosin Reservoir. It was during that battle that he said the famous line, "We've been looking for the enemy for some time now. We've finally found him. We're surrounded. That simplifies things."
