Korean War: Bloody Gulch massacre: Seventy-five American POWs are massacred by the North Korean Army.

The Korean War was an armed conflict on the Korean Peninsula fought between North Korea and South Korea and their allies. North Korea was supported by China and the Soviet Union, while South Korea was supported by the United Nations Command (UNC) led by the United States. The conflict was one of the first major proxy wars of the Cold War. Fighting ended in 1953 with an armistice but no peace treaty, leading to the ongoing Korean conflict.

The Bloody Gulch massacre was a war crime that took place in the Korean War on August 12, 1950, in "Bloody Gulch", west of Masan, South Korea. After a successful attack on two US artillery battalions that killed or injured hundreds of US soldiers, North Korea's Korean People's Army (KPA) 13th Regiment then killed 75 US Army prisoners of war. Otherwise this was one of the smaller engagements of the Battle of Pusan Perimeter. The 75 soldiers were from the 555th Field Artillery Battalion of the US 24th Infantry Division and the 90th Field Artillery Battalion of the US 25th Infantry Division.

The Korean People's Army encompasses the combined military forces of North Korea and the armed wing of the Workers' Party of Korea (WPK). The KPA consists of five branches: the Ground Force, the Naval Force, the Air Force, the Strategic Force, and the Special Operations Forces. It is commanded by the WPK Central Military Commission, which is chaired by the WPK general secretary, and the president of the State Affairs; both posts are currently headed by Kim Jong Un.
