German commerce raider in WWI

"Count Dohna and his "Moewe" - a silent film procured by the US Army Signal Corps and placed into the public domain files of the US National Archives, showing actual scenes of German commerce raiding on the seas in World War I. The actual film was "taken with German camera, lens and film by the first made of the "Moewe," Captain-lieutenant Wolf." The "Moewe" was the name of the combat-raiding ship. This is some pretty darned impressive footage of actual sea combat in the early years of the First World War.
