In 1943, Bradley was moved to the Santo Tomas Internment Camp in Manila. It was there that she and several other imprisoned nurses earned the title "Angels in Fatigues" from fellow captives. For the next several months, she provided medical help to the prisoners and sought to feed starving children by shoving food into her pockets whenever she could, often going hungry herself. As she lost weight, she used the room in her uniform for smuggling surgical equipment into the prisoner-of-war camp. At the camp she assisted in 230 operations and helped to deliver 13 children.
