Elżbieta Zawacka

Elżbieta Zawacka (; 19 March 1909 – 10 January 2009), known also by her war-time Zo, was a Polish freedom fighter during World War II, a Special Operations Executive (SOE) agent, and university professor. She was promoted to brigadier general of the Polish Land Forces (after Maria Wittek the second woman to hold this rank) by President Lech Kaczyński on 3 May 2006. Sometimes called "the only woman among the Cichociemni" (Silent Unseen), she served as a courier for the Polish Home Army, carrying letters and other documents from Nazi-occupied Poland to the Polish government-in-exile in London and back. Her regular route ran from Warsaw through Berlin and Sweden to London. She was also responsible for organizing routes for other couriers of the Home Army. Provided by Wikipedia
