The Eagle (1959 film)

The Eagle Polish Orze is a 1959 Polish war film directed by Leonard Buczkowski. It is based on the true story of the Polish World War II submarine ORPOrze. Since the real Orze was sunk in the war, to assure authenticity her role was played by her sister ship, the ORPSp. The film was entered into the 1st Moscow International Film Festival. Basically the story is freely based on the socalled Tallinnepisode of the Polish submarine Orzel, which in Sep. 1939 entered the harbour of then still neutral Estonia to leave her commanding officer with symptoms of illness. The Estonian authorities tried to intern the sub under the pressure from the NaziGermany, but the Orzel escaped.
