In the early days of the Korean War, other American officers observed, photographed and confidentially reported on such wholesale executions by their South Korean ally, a secretive slaughter believed to have killed 100,000 or more leftists and supposed sympathizers, usually without charge or trial, in a few weeks in mid-1950.

Extensive archival research by The Associated Press has found no indication Far East commander Gen. Douglas MacArthur took action to stem the summary mass killing, knowledge of which reached top levels of the Pentagon and State Department in Washington, where it was classified “secret” and filed away.

On June 29, 1950, as the southern army and its U.S. advisers retreated southward, reports from Seoul said the conquering northerners had emptied the southern capital’s prisons, and ex-inmates were reinforcing the new occupation regime.

In a confidential narrative he later wrote for Army historians, Lt. Col. Rollins S. Emmerich, a senior U.S. adviser, described what then happened in the southern port city of Busan, formerly known as Pusan.

Emmerich was told by a subordinate that a South Korean regimental commander, determined to keep Busan’s political prisoners from joining the enemy, planned “to execute some 3500 suspected peace time Communists, locked up in the local prison,” according to the declassified 78-page narrative, first uncovered by the newspaper Busan Ilbo at the U.S. National Archives.

Emmerich wrote that he summoned the Korean, Col. Kim Chong-won, and told him the enemy would not reach Busan in a few days as Kim feared, and that “atrocities could not be condoned.”

But the American then indicated conditional acceptance of the plan.

“Colonel Kim promised not to execute the prisoners until the situation became more critical,” wrote Emmerich, who died in 1986. “Colonel Kim was told that if the enemy did arrive to the outskirts of (Busan) he would be permitted to open the gates of the prison and shoot the prisoners with machine guns.”
