Clemons was awarded the
Distinguished Service Cross while serving as a platoon leader in Company K,
31st Infantry Regiment for "heroism in action against the enemy in the vicinity of Kumhwa, Korea, October 28, 1952", a part of the
Battle of Triangle Hill. In that action, Clemons led the attack platoon in a counterattack, leading multiple attacks with limited ammunition, including hand-to-hand fighting. On April 17, 1953, after being assigned as the commanding officer of Company K while still a first lieutenant, he led the counterattack on
Pork Chop Hill. He was awarded the Silver Star for his part in this action. In his Silver Star citation, Clemons's "gallantry, personal example, and outstanding leadership" was cited as the major factor in taking and holding the position, commenting further that "rarely in combat history has a force of the size committed on Pork Chop taken such losses ... and nevertheless continued to hold their position". At one point during the battle, Clemons estimated that he had lost approximately half his force. During the battle Clemons was reinforced by G Company,
17th Infantry Regiment, commanded by his brother-in-law,
Walter B. Russell Jr. Clemons and his command served as the centerpiece of a book by
S.L.A. Marshall called
Pork Chop Hill which was turned into a 1959 movie,
Pork Chop Hill. In the movie, he was portrayed by
Gregory Peck, and Clemons served as a technical adviser. == Later career ==
