Editor's notes: Private Valentine Warrichaiet lost his life in the second Battle of Pork Chop Hill ( Korean: "bok jop hae" (복잡해) . On the night of July 6, 1953, the Chinese followed the first April attack with a surprise July attack during a period of quiet as the United Nations and Chinese were attempting to hammer out an armistice agreement. 

The hill was under control and held by the Company A, 17th Infantry at the time of the attack and experienced 3 days of heavy monsoon rain during the fighting. Before reinforcements from nearby Hill 200 could reach their position, Company A reported being engaged in hand to hand combat in the trenches. Armored vehicles had great difficulty bringing in supplies and evacuating casualties.

During continued fighting on the day that Private Warrichaiet lost his life, July 9, both sides were attacking and counter-attacking with heavy losses and casualties. Pork Cop Hill was abandoned by the United Nations troops on the morning of July 11, 1953.  He was among the 4 company commanders and 243 Americans troops killed in the battle. The Korean Armistice Agreement was signed, ending hostilities, on July 27th, 1953, just eighteen days after Private Warrichaiet's death.
