She carried out two successful raiding voyages against British trade during the summer of 1814, in the course of which she captured two brig-sloops of the Royal Navy.

She remained at Portsmouth, New Hampshire, until late spring awaiting sailing orders and, upon receipt of them, put to sea on 1 May 1814 for a war cruise to the western approaches to the English Channel.

Wasp captured her first vessel, the 207-ton barque Neptune, on 2 June 1814, embarked her crew as prisoners, and burned the prize at sea.

Wasp encountered the 131-ton armed brig Pallas on 18 June 1814, captured her, apparently without resistance, and scuttled her.

On 28 June 1814, Wasp came upon the 18-gun Cruizer-class brig-sloop HMS Reindeer some 225 miles west of Plymouth, England, and brought her to battle.

The fight lasted only 19 minutes, but during that brief span of time the two ships traded a murderous fire of grape and solid shot.

Reindeer had suffered 25 men killed, including her captain, Commander William Manners, and 42 wounded.

However, just as Wasp began to lower the boat for the prize crew, the lookout sighted another enemy brig standing toward the two adversaries.

On 21 September 1814, an eight-gun brig, Atalanta (or Atlanta), ran afoul of Wasp, and she, too, suffered the ignominy of capture.

Deeming Atalanta too valuable to destroy, Blakeley placed her under the command of Midshipman David Geisinger and sent her to the United States.
