In 1943, Senesh joined the British Army and volunteered to be parachuted into Europe. The purpose of this operation was to help the Allied efforts in Europe and establish contact with partisan resistance fighters in an attempt to aid beleaguered Jewish communities. Senesh trained in Egypt and was one of the thirty-three people chosen to parachute behind enemy lines. With the goal of reaching her native Budapest, Senesh parachuted into Yugoslavia in March 1944 and spent three months with Tito’s partisans. Her idealism and commitment to her cause are memorialized in her poem “Blessed is the Match,” which she wrote at this time.

She was caught almost immediately by the Hungarian police and tortured cruelly and repeatedly over the next several months. Despite these conditions, Senesh refused to divulge any information about her mission. Even the knowledge that her mother was at risk and that she too might be harmed did not compel Senesh to cooperate with the police. At her trial in October 1944, Senesh staunchly defended her activities, and she refused to request clemency. Throughout her ordeal, she remained steadfast in her courage, and when she was executed by a firing squad on November 7, she refused the blindfold, staring squarely at her executors and her fate. Senesh was only 23 years old.
