The Dnieper Flotilla in the Russo-Turkish War of 1787–92 was commanded by Karl Heinrich von Nassau-Siegen. With 51 boats of various types – dubel boats, cossack boats, and others – the flotilla combined with a squadron of 13 seagoing warships of the Black Sea Fleet commanded by John Paul Jones for operations in the Liman (the Dnieper-Bug Estuary), part of the Siege of Ochakiv of 1788. The Turkish fleet was roughly equal in large ships, but somewhat inferior in smaller craft to the Dnieper Flotilla.
