the North Atlantic. During his tour of duty aboard that warship, she made two successful war cruises, capturing nine prizes off the east coast of the United States during the first and four off the Atlantic seaboard of South America during the second. Promoted to Master Commandant in July 1813, he took command of the sloop-of-war Peacock later in the year. On 12 March 1814, he put to sea with his new command bound for the naval station at St. Mary's, Georgia. After delivering supplies to that installation, he encountered the British brig Epervier off Cape Canaveral, Florida. Peacock emerged victorious from a brisk 45-minute exchange with that opponent, inflicting 10 times her own losses on the enemy. For his role in the victory, Warrington received the Thanks of Congress in the form of a Congressional Gold Medal, and of the state of Virginia in the form of a gold-hilted sword. He was also elected an honorary member of the New York Society of the Cincinnati. Warrington took his prize into Savannah, Georgia, and then embarked upon his second cruise on 4 June. On that voyage, which took him to the Grand Banks, the Irish coast, the Shetland Islands, and the Faroe Islands, he took 14 prizes. After returning via the West Indies to New York, Warrington took Peacock on her third and final war cruise. His sloop-of-war stood out of New York with the Hornet and Tom Bowline on 23 January 1815, sailed around the Cape of Good Hope, and entered the Indian Ocean. Unaware that peace had been concluded in December 1814 at Ghent, Belgium, Warrington led his little force on another successful foray against British commerce. After taking three prizes in the Indian Ocean, he entered the East Indies in search of more game. On 30 June, he encountered the East India Company brig Nautilus in the Sunda Strait and attacked her, despite having been told that peace had been concluded. After a sharp, unequal action which cost the British ship 15 men including her first lieutenant, she surrendered to Warrington. Warrington then released the prize and started for home. Peacock arrived back in New York on 30 October 1815. In 1816, he commanded Macedonian briefly for a voyage to Cartagena, Spain, to convey there Christopher Hughes, the representative of the United States at negotiations over the release of some Americans imprisoned by Spanish authorities.
