V 103 "Sylvia" was a German steamer which was converted into a "Vorpostenboot" for the Kriegsmarine during World War II. The ship participated in the German invasion of Denmark in April 1940, escorting the steamer "Rugard" and tugs "Monsun" and "Passat" alongside V 102 "Cressida" and several minesweepers. The group landed three companies of the 170th Infantry Division at Middlefart.
