The Polish cavalry in Sochaczew photograph supposedly depicts the eponymous charge of the Polish cavalry in Sochaczew during the Battle of the Bzura in 1939, but is now believed to have been taken during the filming of Hans Bertram's propaganda movie "Kampfgeschwader Lützow" in 1940. The photograph is still one of the most widely used depictions of Polish cavalry during the 1939 invasion of Poland.
