The Orzel was a Polish submarine that escaped the 1939 Nazi Germany invasion of Poland at the beginning of World War Two. Her journey began in Poland and took her to Estonia, where she and her crew escaped being interned by the Estonians at the behest of the Nazis. After her escape, she sailed through the Baltic Sea, dodging German air and naval forces, and fled to the United Kingdom. After a refitting, she continued her fight against the Nazis off the coast of Norway, where she almost uncovered the Nazis' invasion of Norway before it even began.
