This factual mistake happens in the German version. In the movie a title card reads: "Capture of Baghdad from the Turks: General Maude's Victory, March 11, 1917". This of course means that British forces under General Maude have captured Baghdad. However, the German version subtitles this as "Einnahme Bagdads durch die Türken: General Maudes Sieg, 11. März 1917". This translates as "Turkish forces capture Baghdad: General Maude's Victory, March 11, 1917". An obvious mistake.
