This postcard is of the Battleship S. M. S. Kaiser Friedrich III. [Friedrich was Kaiser Wilhelm I’s son and Kaiser Wilhelm II’s father. He is known as the “99-Day Kaiser,” as his rule spanned a brief three-month period during 1888, when Germany had three Kaisers within ninety-nine days]. She was commissioned in 1898, but by WW I she had become an outmoded relic. The S. M. S. Friedrich III was the lead battleship of a five-ship class. It was assigned to Battleship Squadron Nr 5 along with other older ships. It was used in minor operations early in the war, then as a prison ship, and finally as a floating barracks. It was scrapped in 1920. The ship is depicted going through the Kaiser Canal. The postcard was never mailed.
