World War I: U-139 and Captain Walther Schweiger

Back in November, while at the National Museum of the U.S. Air Force in Dayton, Ohio, I saw they had the weather flag from the German World War I submarine U-139 and a picture of the Lusitania sinking after being hit by a torpedo from Captain Schweiger's U-20. I wrote a follow up about the ship and the man in my RoadDog's RoadLog Blog of this date. //// --Cooter
