The action of 23 April 1794 took place between a British squadron of five frigates under the command of Sir John Borlase Warren and three frigates and a corvette under the command of Chef d'escadre F. Desgarceaux during the French Revolutionary Wars.

[3] Warren promptly set off in pursuit, and at dawn the next day, around 4 a.m., sighted three frigates and a corvette about seven or eight leagues (24.5–28 nautical miles) south-west of Guernsey.

The French formed a line of battle, and Warren signalled his squadron to engage, with his own flagship Flora in the lead, supported by Arethusa.

Taking advantage of the weather gage the British were able to force the French into a close action which lasted for nearly three hours, before the Pomone and Babet surrendered at around 11 a.m.[4] The Engageante and Résolue attempted to escape, and Warren ordered Concorde, Melampus and Nymphe to pursue, as Flora was in no condition to do so.

Having made hasty repairs Concorde came up again to re-engage the Engageante, which eventually surrendered at about 1.45 p.m. Résolue fired a few shots and then made off, pursued by Melampus and Nymphe, who chased her into Morlaix, before returning to assist Concorde which was towing the crippled Engageante to port.
