The OTZMA X Songbook - Eli, Eli (1995)

A mandatory entry in the American Jew's songbook is Hannah Szenes's "Eli, Eli."  Her story of Jewish nationalism and anti-Nazi heroism is legendary:

In 1941, Hannah joined Kibbutz Sdot Yam and then joined the Haganah, the paramilitary group that laid the foundation of the Israel Defense Forces. In 1943, she enlisted in the British army in the Woman's Auxiliary Air Force as an Aircraftwoman 2nd Class and began her training in Egypt as a paratrooper for the British Special Operations Executive (SOE).  In March 1944, she and two male colleagues, Yoel Palgi and Peretz Goldstein, were parachuted into Yugoslavia and joined a partisan group. After landing, they learned the Germans had already occupied Hungary, so the men decided to call off the mission as too dangerous.  Szenes continued and headed for the Hungarian border. At the border, she was arrested by Hungarian gendarmes, who found the British military transmitter she was carrying, used to communicate with the SOE and other partisans. She was taken to a prison, stripped, tied to a chair, then whipped and clubbed for three days. The guards wanted to know the code for her transmitter so they could find out who the other parachutists were. She did not tell them, however, even when they brought her mother into the cell and threatened to torture her too.

Whilst in jail, Szenes used a mirror to flash signals out of the window to the Jewish prisoners in other cells, and communicated with them using large cut-out letters in Hebrew that she placed in her window one at a time and by drawing the Magen Davidn the dust. She tried to keep their spirits up by singing, and through all the things Szenes went through she still kept her spirit high and stayed true to her mission. -  Wikipedia
