Congress required extensive repairs before recommissioning with Captain John Rogers in command. She performed routine patrols early in 1812 before war was declared on 18 June. Captain
John Smith assumed command on 11 July 1812 and took her to join Rodgers' squadron, where she sailed in company with , ,
President, and . Almost immediately Rogers was informed by a passing American merchant ship of a fleet of British merchantmen en route to Britain from Jamaica.
Congress sailed along in pursuit, but was interrupted when
President began pursuing
HMS Belvidera on 23 June.
Congress trailed behind
President during the chase and fired her bowchasers at the escaping
Belvidera. Unable to capture
Belvidera, the squadron returned to the pursuit of the Jamaican fleet. On 1 July they began to follow a trail of coconut shells and orange peels the Jamaican fleet had left behind them. Sailing to within one
day's journey of the English Channel, the squadron never sighted the convoy and Rodgers called off the pursuit on the 13th. During their return trip to Boston,
Congress assisted in the capture of seven merchant ships, including the recapture of an American vessel. Making her second cruise against the British with
President,
Congress sailed from Boston on 8 October. On the 31st of that month, both ships began to pursue , which was escorting two merchant ships.
Galatea and her charges were chased for about three hours, during which
Congress captured the merchant ship
Argo. In the meantime,
President kept after
Galatea but lost sight of her as darkness fell.
Congress and
President remained together during November but they did not find a single ship to capture. On their return to the United States they passed north of Bermuda, proceeded towards the
Virginia capes, and arrived back in Boston on 31 December. During their entire time at sea, the two frigates captured nine
prizes.
Congress and
President were
blockaded in Boston by the Royal Navy until they slipped through the blockade on 30 April 1813 and put to sea for their third cruise of the war. On 2 May they pursued but she outran them both and escaped.
Congress parted company with
President on the 8th and patrolled off the
Cape Verde Islands and the coast of Brazil. She only captured four small British merchant ships during this period and returned to the
Portsmouth Navy Yard for repairs in late 1813. By this time of the war, materials and personnel were being diverted to the
Great Lakes, which created a shortage of resources necessary to repair her. Because of the amount of repairs she needed, it was decided instead to place her in ordinary, where she stayed for the remainder of the war. Louis F. Middlebrook in Vol. LXIII, October 1927 of Essex Institute Historical Collections listing following prizes taken by her under the command of Captain John Smith:November 1, 1812, off Western Islands, the British
