Sarah Aaronsohn (Hebrew: שרה אהרנסון; 5 January 1890 – 9 October 1917) was a member of Nili an acronym for Netzach Israel Lo Ishaker - The Eternal One of Israel does not deceive, (1 Samuel 15:29), a ring of Jewish spies working for the British in World War I, and a sister of notable agronomist Aaron Aaronsohn. She is often referred to as the "heroine of Nili."
Sarah Aaronsohn was born and died in Zichron Yaakov, which at the time was part of Ottoman Syria. Her parents were Zionists from Romania who had come to Ottoman Palestine as some of the first settlers of the First Aliyah and were founders of the moshav where Aaronsohn was born. Encouraged by her brother Aaron, she studied languages and was fluent in Hebrew, Yiddish, Turkish and French, had reasonable command of Arabic and taught herself English. She married Haim Abraham, an older and affluent merchant from Bulgaria, and lived briefly with him in Istanbul; but the marriage was an unhappy one and she returned home to Zichron Yaakov in December, 1915.
Decision to spy
On her way from Istanbul to Haifa, Aaronson witnessed part of the Armenian genocide. She testified to seeing hundreds of bodies of Armenian men, women, children, and babies; sick Armenians being loaded onto trains; and up to 5,000 Armenians massacred by being bound to a pyramid of thorns, then set alight. After her trip to Haifa, any allusions to Armenians upset her greatly. According to Chaim Herzog, Aaronsohn decided to assist British forces as a result of what she had witnessed.
Aaronsohn, her sister Rivka Aaronsohn, and her brothers Aaron Aaronsohn and Alexander Aaronsohn, with their friend (and fiance of Rivka) Avshalom Feinberg formed and led the Nili spy organization. Aaronsohn oversaw operations in Palestine of the spy-ring and passed information to British agents offshore. Sometimes she travelled widely through Ottoman territory collecting information useful to the British, and brought it directly to them in Egypt. In 1917, her brother Alex urged her to remain in British-controlled Egypt, expecting hostilities from Ottoman authorities; but Aaronsohn returned to Zichron Yaakov to continue Nili activities. Nili developed into the largest pro-British espionage network in the Middle East, with a network of about 40 spies.
Discovery and death
In September 1917, the Ottomans intercepted her carrier pigeon carrying a message to the British and decrypted the Nili code. In October, the Ottomans surrounded Zichron Yaakov and arrested numerous people, including Aaronsohn. Her captors tortured her father in front of her. She endured four days of torture herself, but she released no information beyond what she thought of her torturers. Before she was to be transferred to Damascus for further torture, she asked permission to return to her home in Zichron Yaakov to change her blood-stained clothes. While there, she managed to shoot and kill herself with a pistol concealed under a tile in the bathroom. According to Scott Anderson, in his book Lawrence in Arabia, Aaronsohn shot herself in the mouth on Friday, October 5, 1917. "Even this did not end the torment of Sarah Aaronsohn. While the bullet destroyed her mouth and severed her spinal cord, it missed her brain. For four days she lingered in agony." She died October 9, 1917. In her last letter, she expressed her hope that her activities in Nili would bring nearer the realization of a national home for the Jews in Eretz Israel.
Because of the Jewish views on suicide, Aaronsohn was denied a traditional burial in a Jewish cemetery. However, refusing a Jewish burial for a Jewish war hero was naturally unpopular. As a compromise, a small fence was placed around her grave in the cemetery (symbolically removing her grave from the surrounding hallowed ground).
Following her death, Aaronsohn became widely commemorated. She was the first example of a "secular, active death of a Jewish-Zionist woman for the nation, unprecedented in both religious martyrdom and in the Zionist tradition established in Palestine."  Annual pilgrimages to her tomb in Zikhron’s cemetery started in 1935. After the Six Day War of 1967 the memory of Aaronsohn and of Nili became a part of Israel's cult of heroism, officially recognized by the Labor Party and celebrated in children’s literature.
