17 Dec 44: Aftermath of the Malmedy Massacre: some 70 members of Battery B found killed after capture
In the second day of the Battle of the Bulge, elements of the 285th US Field Artillery Observation Battalion were taken prisoner only to be shot by an SS force.
As soon as the SS machine gunners opened fire, the American POWs panicked. Some tried to flee, but most were shot where they stood. A few sought shelter in a cafe at the crossroads. The SS soldiers set fire to the building, and shot all who tried to escape the flames. Some in the field had dropped to the ground and pretended to be dead when the shooting began. However, SS troops walked among the bodies and shot any who appeared to be alive.
Later, a few survivors emerged from hiding and returned through the lines to nearby Malmedy, where American troops held the town. Eventually, 43 survivors found refuge, some with the help of Belgian civilians.
Testimony from the survivors was taken hours after the massacre. All the accounts were similar and corroborated each other, though the men had no opportunity to discuss the events. By late evening of the 17th, rumors that the enemy was killing prisoners had reached the forward American divisions. There are claims that some American forces killed German prisoners in retaliation.
The Malmedy Massacre, as well as others committed by the same German unit on the same day and following days, resulted in the Malmedy massacre trial, part of the Dachau Trials of 1946. More than 70 Germans were charged and 43 death sentences were pronounced (none of which were carried out) and 22 life sentences.

Overshadowed by the magnitude of the Malmedy Massacre, 11 African-American soldiers of the 333rd Field Artillery Battalion were captured on this same day near the town of Wereth after they became separated from their unit.
The SS troops massacred all eleven after brutally torturing them. Their remains were found by Allied soldiers two months later, after the Allies re-took the area. The soldiers had their fingers cut off, legs broken, and at least one was shot while trying to bandage a comrade's wounds. Another was reported to have had a knife plunged into his eye socket.
These men are now memorialized as the Wereth Eleven.
