Michel (HSK-9) was an auxiliary cruiser of Nazi Germany's Kriegsmarine that operated as a merchant raider during World War II. Built by Danziger Werft in Danzig 1938/39 as the freighter Bielsko for the Polish Gdynia-America-Line (GAL), she was requisitioned by the Kriegsmarine at the outbreak of World War II and converted into the hospital ship Bonn. In the summer of 1941, she was converted into the auxiliary cruiser Michel, and was commissioned on 7 September 1941. Known as Schiff 28, her Royal Navy designation was Raider H. She was the last operative German raider of World War II.
When the AMC Widder returned from her cruise to Germany, her engines were almost worn out. The hospital ship Bonn was converted into an AMC and mounted the weapons used by the Widder.
Although Michel was scheduled to leave at the end of November 1941, she was unable to sail until March 1942 because of reconstruction delays. She then moved under heavy escort through the English Channel to a port in occupied France. She set off on her cruise sailed on 20 March 1942,commanded by FK (later KzS) Helmuth von Ruckteschell, the former commander of HSK 3, the raider Widder).
