HMS Boreas was a 28-gun sixth-rate frigate of the Royal Navy. Built by Israel Pownoll at Woolwich Dockyard and launched in 1757, she was one of five frigates of the class built of fir rather than oak. Boreas saw service during the Seven Years' War and took part in two actions at sea. She assisted in the capture of the 36-gun French frigate Diane in April 1758, and her most famous engagement was the capture of the French frigate Sirène in October 1760. She was sold out of the service in 1770.
Boreas was ordered on 18 April 1757 and laid down on 21 April that year at the Admiralty yards at Woolwich Dockyard. She was launched on 29 July 1757 and completed by 6 September 1757.[1] She initially cost £6,314.9.10d, this rising to £9,193.18.3d when the cost of fitting her out was included. She was one of five frigates of the class built of fir rather than oak. Fir was cheaper and more abundant than oak and permitted noticeably faster construction, but at a cost of a reduced lifespan; the fir-built Coventry-class vessels lasted an average of eight years, three times less than their oak-built equivalents. The fir-built ships also required greater maintenance after periods at sea, averaging £1,573 in repairs for each year of service compared with £1,261 for comparable vessels built from oak.[2]
The frigate was named after Boreas, the Greek god of the north wind and bringer of winter. The naming followed a trend initiated in 1748 by John Montagu, 4th Earl of Sandwich, in his capacity as First Lord of the Admiralty, of using figures from classical antiquity as descriptors for naval vessels. A total of six Coventry-class vessels were named in this manner; a further ten were named after geographic features including regions, English or Irish rivers, or towns.[3] [4]
In sailing qualities Boreas was broadly comparable with French frigates of equivalent size, but with a shorter and sturdier hull and greater weight in her broadside guns. She was also comparatively broad-beamed with ample space for provisions and the ship's mess, and incorporating a large magazine for powder and round shot. Taken together, these characteristics would enable Boreas to remain at sea for long periods without resupply.[5] She was also built with broad and heavy masts, which balanced the weight of her hull, improved stability in rough weather and made her capable of carrying a greater quantity of sail. The disadvantages of this comparatively heavy design were a decline in manoeuvrability and slower speed when sailing in light winds.[6]
Her designated complement was 200, comprising two commissioned officers a captain and a lieutenant overseeing 40 warrant and petty officers, 91 naval ratings, 38 Marines and 29 servants and other ranks.[7] Among these other ranks were four positions reserved for widow's men fictitious crew members whose pay was intended to be reallocated to the families of sailors who died at sea.[7]
Boreas was commissioned for the first time in August 1757 under Captain Robert Boyle, who was to command her for the next two years. Her rigging and fitout were completed by September and she was sailed to Portsmouth to take on her guns. Flaws in her design were apparent even at this early stage; in December 1757 Captain Boyle advised Admiralty that the fir planks adjacent to the hatchways were already badly worn, as were the strakes along the hull. Boyle unsuccessfully recommended that the hatchway timbers and the hull be re-covered with elm. He also observed that the aft hatchway had been constructed directly above the entrance to the magazine, which "may be of fatal consequence in time of action." Further, the sides of the vessel above the level of the deck were too low, leaving the crew exposed to enemy fire should Boreas run alongside an opposing ship.[2]
Boyle's concerns went unheeded, and Boreas was put to sea in early 1758. In April she assisted in the capture of the 36-gun French frigate Diane. Boyle then sailed her to America on 21 June 1758 and she was subsequently involved in the operations off Louisbourg that year. Boreas shared in the proceeds of the capture of the merchantman Foudroyant and the schooner Two Brothers, captured off Louisbourg. She also shared in the proceeds of the taking of the Bienfaisant and Echo, and the proceeds from the burning, sinking, or destroying the French warships Prudent, Entreprennante, Celebre, Capricieux, Apollon, and Fidelie in the harbour of Louisbourg, as well as the sundry naval stores, the recapture of the snow Muscliff, the sloop Dolphin, and the prize sloop Sellerie. In November 1762 Boreas was paid head money for the privateers Bayonese and Leon, captured while she was under Boyle's command.
A period of service in the English Channel with Admiral George Rodney's squadron followed in 1759. On 28 March Boreas captured the Demoiselle, which was coming from San Domingo. Later, Boreas took part in the bombardment of Le Havre on 3 July that year. At some point Boreas also recaptured Hazards Bounty.
She came under the command of Captain Samuel Uvedale in February 1760, and he sailed her to Jamaica on 26 March. On 30 August that year he chased the privateer St Michel ashore near Cape St Nicholas Mole and burnt her. While under Uvedale's command, Boreas captured the privateer ships Intrepid and Dragon.
Another action occurred on 18 October when Admiral Charles Holmes in (50 guns) took Boreas and (20 guns) to intercept a French convoy in the Windward Passage. After sighting the five French vessels on the morning of 17 October, the British gave chase. Light winds slowed the chase so it was evening before Boreas could engage the 32-gun frigate Sirène. French fire disabled Boreas aloft with the result that Boreas could not engage Sirène again until the following afternoon.[8] Boreas emerged victorious from the engagement, capturing Sirène, which suffered about 80 men killed and wounded, most of whom died later; Boreas lost only one man killed and one wounded. The French 20-gun corvette Valeur, struck to Lively. Hampshire chased the merchant frigate Prince Edward on shore where her crew set fire to her, leading her to blow up., Boreas,, and, shared by agreement in the prize money for Sirene, Valeur, the snow Maria, the sloop Elizabeth, and the sloop Pursue.
On 19 October, Hampshire, with Lively and Valeur, cornered the King's frigate Fleur de Lis in Freshwater Bay, a little to leeward of Port-de-Paix; her crew too set her on fire. The merchant frigate Duc de Choiseul, of 32 guns and 180 men under the command of Captain Bellevan, escaped into Port-de-Paix.
In late 1760, boats under the command of Lieutenant Millar, first lieutenant of and Lieutenant Stuart, first lieutenant of Boreas, cut out the privateers Vainquer and Mackau from Cumberland Harbour, Cuba. The French were forced to burn another, Guespe, to prevent her capture. Trent lost three men killed and one man wounded and one man missing, and Boreas lost one man killed and five men wounded; French casualties are unknown. All the casualties occurred in taking Vainquer as Mackau did not resist. Boreas also lost her barge, sunk in the boarding. Vainquer was armed with 10 guns, 16 swivels, and 90 men; Mackau had 6 swivels and 15 men; Guespe had 8 guns and 86 men. In April, Boreas was paid for the capture of the Vrouw Jacoba, and the brigantine Leon.
Boreas then returned to Jamaica to undergo repairs, which lasted into 1761. Boreas went on to capture the privateer Belle-Madeleine on 18 December 1761. Then from 6 June until 13 August 1762, she took part in the capture of Havana. After this, she returned to Britain as a convoy escort along with and, and was surveyed at Woolwich.
A small repair followed, lasting until May 1763. Captain Richard Hughes took over command in April 1763, serving off North Foreland until 1766. Captain Constantine Phipps succeed him in 1767, and was himself replaced by Captain Digby Dent the following year. Both commanded Boreas in the Channel.
Boreas was surveyed for a final time on 23 May 1770. She was sold a month later on 29 June for the sum of £280.[1]
