 Later, following their initial incarceration at Camp O'Donnell, most American POWs were moved to Cabanatuan, while their Filipino comrades remained at Camp O'Donnell.Some of the American prisoners who were interned at Camp O'Donnell were sent to Fort Stotsenburg and were forced to perform menial labor for their Japanese conquerors.These prisoners were considered the lucky ones as the others who remained in O'Donnell or Cabanatuan were moved aboard freighters to Japanese slave labor camps in the home islands.
