[1][2] In April Sub-Lieutenant George Gover Miall, the commander of the schooner Chebuctoo, was ordered to act as Lieutenant-Commander of the Bream.

[b] While Bream was in the Chesapeake Bay a mutiny broke out that Lieutenant Bartholomew George Smith Day helped suppress.

While in Bream, Simpson carried specie to St. John's, Newfoundland and was frozen up at Louisburg, Cape Breton, which materially harmed his health.

The British government did this as a conciliatory measure, but Bream, under Simpson's command, returned the men to the US Navy at Boston on 11 July 1812,[10] nearly a month after war had already broken out between the two nations.

[11] On 9 August Bream captured the American 3-gun privateer sloop Pythagoras and her crew of 35, under the command of Cyrus Libby.

[12][13] The Vice admiralty court in Halifax, Nova Scotia, condemned Pythagoras, of 42 tons (bm), Cyrus Libby, master, sailing from Saco, Maine.

[14] In October Admiral Sir John Borlase Warren dispatched Shannon and Bream to rescue the crew and offload the money aboard the frigate Barbadoes, which had been wrecked on Sable Island.

From late 1812 to 1813 Bream served in the Bay of Fundy as part of a small squadron under the command of Captain Alexander Gordon in Rattler.

[1] Under Hare's command Bream engaged in a successful campaign of guerre de course against American shipping on the Maine coast.

On 19 May, Rattler, with Bream's assistance, captured the American 18-gun privateer Alexander off Kenebank (Kennebunk, Maine).

[23] Capturing her required an eight-hour running fight, including a fifty-minute battle at close quarters off Brier Island in the Bay of Fundy.

Hare, Commander of H.M. Schooner Bream, is respectfully requested to accept the sincere thanks of Captain Ernest A. Ervin, commander of the American privateer Wasp, of Salem, for the very courteous, friendly and gentlemanlike treatment received while a prisoner on board, the deportment observed toward him being more like a friend and countryman than that of a declared enemy.

[29] Beer commanded Bream at the capture of Moose Island (Maine) in July, and was present at the attack on Baltimore on 13 September.

[32] Similarly Bream shared in the prize money for the schooner Mary and the goods from the transports Lloyd and Abeona, captured in the Chesapeake between 29 November and 19 December.
