North Korean regulars on this date in 1950 committed a notorious mass execution upon 41 U.S. prisoners during the Korean War.
The Hill 303 massacre took place upon a 303-meter hill guarding the northern approach to Waegwan. In mid-August of 1950, said hill was defended by the U.S. Army’s 2nd Battalion, 5th Cavalry Regiment, 1st Cavalry Division, which narrowly escaped encirclement there by the advancing North Koreans.
Most of them escaped encirclement.
It’s a barely remembered atrocity in a war that America has consigned to forgetfulness; the massacre has seemingly never had anything like a thorough investigation. An indelible horror to the five men* who lived to tell the tale, its narrative outline is crude timelessness itself: holding these 42 U.S. POWs for two days, the North Koreans were themselves pummeled by a counterattack on the fiercely-fought hill;** unable to continue guarding the Americans, their captors fusilladed them.
This indiscriminate mass firing mere minutes ahead of the American approach was far from a thorough affair — hence the survivors, who were subsequently able to point out some of the captured Koreans who took part.

As a result of this and other summary battlefield executions, U.S. Gen. Douglas MacArthur addressed a threatening leaflet that was heavily dropped behind North Korean lines, threatening to “hold you and your commanders criminally accountable” according to the recent Nuremberg precedent.
There’s a monument to this gratuitous bloodbath that’s been recently installed, at the site of the shooting which is also nearby to a still-extant U.S. Army base called Camp Carroll. (The stone displays the date “June 25, 1950” — which denotes the start of the war, and not the day of the massacre.)
* Even the exact figures involved are a bit slippery. I believe we have 37 humans killed out of 42 captured, leaving five survivors. Some sources give it as 41 (attempted) executions with four survivors. A private named Frederick Ryan apparently was given last rites and declared dead on the scene but miraculously survived, possibly accounting for the variance.
