[3] Granville Hough stated that the vessel American Tartar had been Britannia, out of New York, but then had become a privateer with a letter of marque from Massachusetts.

[6] American Tartar encountered the British merchantman Pole, Maddock, master, on 12 July at 50°N 20°W / 50°N 20°W / 50; -20 (or 56°N 26°W / 56°N 26°W / 56; -26).

[6] On the 15th, American Tartar captured Royal Bounty, of 300 tons (bm), William Kerr, master.

Five days later, she captured the ship Nautilus, George Corney, master, off Isle of Lewis.

On 28 July American Tartar was off Norway where she captured the ships Peggy and Thomas and Elizabeth, and the brig Fanny.

However, HMS Diamond's tender recaptured Royal Bounty on 22 September off Cape Ann and sent her into Halifax.

[9][10] The tender was the American privateer schooner Buckram, John Cross, master, that Diamond had captured on 17 September in Boston Bay.

[2] Lloyd's List (LL) reported that American Tartar had been armed with 28 guns and had had a crew of 200 men.

[11] Admiral John Montague purchased American Tartar at Newfoundland on 9 October 1777 and renamed her HMS Hinchinbrook (or Hinchinbroke).

[12] Commander John Brudenel (or Bradenel) had commissioned Hinchinbrook in September, but she was not formally registered and renamed until 25 February 1778.

LR for 1798 showed Blenheim with Maxwell, master, Blaydes, owner, and trade Hull–Davis Strait.

[15] Another source gives Blenheim's catch for 1798 as 18 whales, that yielded 310 butts of oil and nine tons 13CWT of whalebone.

Her crew, fearing the press gang, had locked her master, William Mitchenson, and the pilot in the cabin.

As a boat from Nonsuch again tried to come alongside, the crew of Blenheim fired a swivel gun loaded with grapeshot, and again wielded their lances.

Another account reports that Blenheim's crew pelted the navy men with spears, capstan bars, handspikes, other offensive weapons, and also several large iron shot.

When the boats from the naval vessels withdrew, the crew aboard Blenheim slipped ashore and disappeared.

[20] On 2 August 1806 Sirène, capitaine de frégate Le Duc, and Revanche, capitaine de frégate Lambert, captured the Greenland whalers Holderness, Swan, master, and Blenheim, Welburn, master, both of and for Hull.
