Galleys remained a mainstay of North African corsair fleets and continued to play a significant role in the Mediterranean well into the 18th century. They made one of their final appearances in a Mediterranean battle in the Battle of Chesma in 1770; they lingered on in the shallow Baltic Sea and took part in the Russo-Swedish War in 1790. Galleys were used, ineffectively, by the Knights of Malta during Napoleon's siege of Valetta in 1798
In America they were used in the Battle of Valcour Island in 1776. Galleys were also used during the Revolutionary War by whalers who used their ships to raid British shipping along the American coast. These raiding parties were useful in supplying the Continental Army with many much needed supplies.
