Only a few survivors of a World War II atrocity are still alive, but on Saturday they’ll be at Jefferson Barracks military cemetery in St. Louis to dedicate a marker at the graves of 139 men who died. They’ll put the marker at the mass grave for many of those victims of the Palawan Massacre. It happened in December of 1944, when prisoners on that island in the Phillipines were herded into a trench and set on fire. Most of those who tried to escape were shot. Until now, only a marble stone marked the gravesite, listing the names of those buried there. The new marker will explain how they died.
