Lloyd's List reported on 28 January 1780 that the French privateer Marquis of Seignety, of Dunkirk, with 160 men, had captured Harpooner, Hill, master, of 56 men and boys. The action had lasted two hours and Marquis had taken Harpooner into Havre de Grace.

On 9 December 1780 HMS Solebay (1763) and HMS Portland (1770) captured two French privateers behind the Isle of Wight after a short action. The two were Comptesse of Buzanisis, Lux, master, and Marques de Seiguley. Each had a crew of 150 men. Comptesse was armed with twenty 12-pounder guns and Marques was armed with twenty 9-pounder guns. In the action Solebay had one man wounded, and Portland had nine, two of whom died later.
