On 23 March 1815 captured in a short battle off Tristan da Cunha. It was one of several engagements that took place after the War of 1812 had ended, and was the final action between British and American forces. The American gunnery was far more effective than the British, despite the two vessels being virtually identical in strength. After exchanges of broadsides and musket fire, the British commander was killed. The British brig rammed the American ship in an attempt to board, but the two were separated and Penguin was disabled shortly afterwards when the foremast fell, forcing the British to surrender. The British brig was too badly damaged to be salvaged and was set ablaze by the victors after its stores and surviving crew were removed.
Background
Late in 1814, the United States Navy had been preparing a small squadron at New York City, to attack British shipping in the Indian Ocean. The squadron consisted of the frigate , the sloops of war and and the brig-rigged tender. On 15 January, Decatur took advantage of a north-westerly gale to break out alone in President, but the frigate went aground on the bar at the harbour mouth and received damage which delayed it for two hours and slowed it. Decatur was unable to turn back as the gale was still blowing, and President was captured after being pursued by the four frigates of the blockading British squadron. The commanders of the other American vessels were not aware of Decatur's fate. When another gale blew up on 22 January, they sailed out in broad daylight under storm canvas and evaded the blockaders through their speed and weatherliness. They made for a pre-arranged rendezvous with President off Tristan da Cunha, which was being used by the Americans as a cruiser base. During the voyage, Hornet lost touch with the other two vessels. Peacock and Tom Bowline reached the rendezvous first, on 18 March, but were then driven off by a gale. Hornet reached the island on 22 March.
Battle
Biddle, commanding Hornet, was about to drop anchor when a strange sail was sighted to the southeast. Biddle at once made for the stranger. This was the , commanded by Captain James Dickenson. Penguin was a new vessel, which had first sailed in September 1814. It carried roughly the same armament as Hornet. Some time earlier, Penguin had been sent from Cape Town to hunt an American privateer which had been attacking homeward-bound East Indiamen. As soon as Hornet was sighted, Dickenson steered for the sloop and prepared to engage. Penguin had the weather gage and for a time, Hornet ran before Penguin, yawing occasionally to avoid being raked. Then Penguin turned up-wind to port at almost the same moment as Hornet turned to starboard. The two vessels exchanged broadsides for 15 minutes, with the range gradually closing from "musket shot". Dickenson turned downwind, to close with Hornet in an attempt to board and capture Hornet, but was mortally wounded. Penguins bowsprit ran across Hornets deck between the main and mizzen masts, badly damaging the American rigging. Penguins crew made no attempt to board Hornet and Hornets crew prepared to board but Biddle stopped them, to continue the gunnery duel. Biddle believed that the British had surrendered at this point and prepared to step aboard Penguin but was wounded by musket balls. As the two vessels separated, Penguins foremast fell, breaking off the bowsprit. The brig had already been severely battered by American shot, and with the brig unable to manoeuvre, Lieutenant McDonald, now in command of Penguin, surrendered. The British had lost 14 men killed and 28 wounded. The brig was "riddled through" and most of the starboard side carronades had been dismounted. By comparison, the Americans had lost only one man killed, one mortally wounded and seven wounded, mostly to musketry. Strikingly, not a single British carronade shot had hit the hull of Hornet.
Aftermath
Penguin was too badly damaged to be repaired and put into service, so the Americans prepared to destroy the brig after removing the stores. Another sail was sighted and the Americans hastily set the Penguin on fire, but the strange sails proved to be Peacock and Tom Bowline. Tom Bowline was sent to a neutral port with Penguins crew, where they were escorted ashore by U.S. Marines. They became the last body of British troops and sailors to be taken prisoner during the war. The two American sloops of war waited in vain for President until 15 April, then headed for the East Indies, as originally intended. On 27 April, they sighted a large ship, which they at first believed to be an East Indiaman, and eagerly headed for it but then realised that their intended victim was a British ship of the line,. The Americans split up. Peacock was the faster of the two sloops and was soon out of sight. Cornwallis had recently been completed at Bombay from teak wood and proved to be very fast and weatherly. Hornet escaped only after a chase lasting two and a half days, during which Biddle had been forced to jettison his stores, ballast, anchors, cables, guns, small arms, capstan, the armourer's anvil, ship's bell and even substantial parts of the forecastle to lighten the sloop enough to outrun Cornwallis. Since Hornet no longer had any fighting strength, Biddle had to turn home. He reached the Cape of Good Hope on 9 May, where he learned that the Senate had ratified the Treaty of Ghent on 18 February, ending the war more than a month before the engagement with Penguin.
