After Italy surrendered in 1943, some of the Decima Flottiglia MAS were on the Allied side of the battle line and fought with the Allies, renaming themselves the Mariassalto. The others fought on the German side and kept their original name but did not operate at sea after 1943, being mostly employed against Italian partisans; some of its men were involved in atrocities against civilians.
