The Butterworth Squadron was a British commercial group of three vessels, Butterworth, Jackal, and Prince Lee Boo, that sailed for the Pacific Ocean from London via Cape Horn in late 1791.Cole, Douglas. Sigismund Bacstrom's Northwest Coast Drawings and an Account of his Curious Career. BC Studies Journal, Summer 1980 The principals financing the expedition were Alderman William Curtis, London ship-owner Theophilus Pritzler, and probably John Perry (shipbuilder), a Blackwall shipbuilder. The leader of the expedition was Captain William Brown, an established whaling captain from the Greenland whale fishery. Sigismund Bacstrom, a naturalist who had previously sailed as a secretary to Joseph Banks, was the surgeon for the expedition. Bacstrom produced a number of drawings during the first part of the voyage, some of which are still in existence.

The expedition is notable for a violent conflict with the Tla-o-qui-aht of Vancouver Island and another reported conflict in Formosa.Ingraham, Joseph.

The vessels The squadron consisted of three vessels, Butterworth, a full-rigged ship four to six times the size of the two sloops that accompanied her. The role of each of the two sloops, Jackal and Prince Lee Boo, was to act as a ship's tender, to scout ahead in shallower waters, or to go off on errands. A man named Priestly owned both sloops.

Butterworth's burthen was 390 to 400 tons. Jackalls burthen 86 tons; Prince Lee Boos was 56 tons. (Burthen was a volumetric measure of cargo capacity, though expressed in tons.) As her burthen and several accounts attest, Prince Lee Boo was somewhat smaller than Jackal.Howay, Frederic W. A List of Trading Vessels in the Maritime Fur Trade, 1785–1825. Edited by Richard A Pierce. Kingston, Ontario, 1973

As was typical of the times, all three vessels were armed. Butterworth carried sixteen guns; the two smaller vessels had nine guns between them.

Butterworth Butterworth was a former French vessel, built in 1778, that came into British hands in 1784. In British hands she became a whaler.Barrington, Daines and Beaufoy, Mark. Possibility of Approaching the North Pole Asserted Her master was Captain William Brown, "an able and expert seaman, regularly brought up in the whale fishery." Brown and Butterworth were Greenland whalers. Brown was highly respected in his field and was consulted by a Fellow of the Royal Society concerning the possibility of approaching the North Pole.

Jackal Jackal (sometimes spelled "Jackall" or "Jack Hall"), had been launched in America in 1782.Lloyd's Register (1792), Seq. №P3. The one contemporary picture of her appears to show a lapstrake sloop with tiller steering, and a removable bowsprit and lightly stayed mast such as were commonly found on longboats and cutters intended to be carried on deck or towed astern of larger vessels. She "showed a tier of ports fore and aft. The greatest part of them were false or only painted, yet they made such a good appearance that for some time we concluded she was a King's cutter or a tender to some man-of-war".

Alexander Stewart served as master of Jackal from her departure from London in late 1791 until Captain Brown took command in late 1793.Vancouver, George, (Lamb, Kaye editor).

Prince Lee Boo Prince Lee Boo had been launched on the Thames in 1791.Lloyd's Register (1792), Seq. №P302. She was named for Prince Lee Boo, a young Palau Islander who traveled to London in 1784.

Masters of Prince Lee Boo were Mr. Richard Sharp, and later Robert Gordon. Upon the death of Robert Gordon in 1795, William Bonallack took command of Prince Lee Boo.

Voyage 1791–1795

Although Sigismund Bacstrom, in a letter to Sir Joseph Banks of Aug. 1791, claimed that the expedition was a commercial venture aimed at bringing back "valuable drugs or natural products" and quite "independent of the new fur trade between Nootka and China," there is no evidence that it was concerned with anything but the lucrative maritime fur trade and the sealery of Tierra del Fuego.

In 1791 as the Butterworth expedition was being organized, Alderman Curtis was actively involved in the debate for opening the trade monopolies to Pacific Ocean trade held by the South Sea Company and the East India Company, particularly in light of the recent Nootka Convention with Spain which opened the Pacific Northwest Coast to British traders.Byrnes, Dan. Outlooks for England's South Whale Fishery, 1784–1800, The Great Circle, October, 1988.,

Sealing/whaling

In early 1792, Butterworth anchored in New Year's Cove on Staten Island, Tierra del Fuego, where they "built a Large Hut and left an Officer with a few Men there to kill Seals and boil Oil."[Bacstrom]

Butterworth would not return for these men until the end of 1793 when Butterworth was "dispatched towards England with directions to fish for whales and seals in passing through the Pacific Ocean, and at Staten Island where Mr. Brown had formed a temporary establishment."

Northwest Coast From Cape Horn the Butterworth squadron sailed to the Marquesas Islands and on to the Vancouver Island, reaching Clayoquot Sound in late July 1792.

In early August, Captain Brown claimed there was an unprovoked attack by the Tla-o-qui-aht People, killing one of his crew and seriously injuring two others, but other vessels present at the time told a different story.

"The English sailors landed at a village in order to rob the natives and actually cut several skins off the natives' backs. Seeing them gathering to defend themselves, the sailors fired on them, by which they said four men were killed. This was before the natives were armed, but they found their mistake as soon as Wickaninnish's warriors turned out, who with two canoes made the whaleboats fly. Had not Captain Magee [of the ship Margaret] fired a cannon shot between them, they would certainly have been cut off ... However, the Englishmen ... took ample revenge. After they were out of port ... they fell in with some canoes fishing. Captain Brown got the men out of them and caused them to be whipped in a most unmerciful manner by the Sandwich Islanders he had on board. After that he threw them into the sea, and the ship Jenny ... being astern, fired at them and ended the tragedy." One of the men killed was the brother of the chief Wickaninnish.

The Butterworth squadron then sailed north to Nootka and Haida Gwaii, returning to Nootka Sound in October. Sigismund Bacstrom, the Butterworth's surgeon and naturalist, left the Butterworth at Nootka on October 15, 1792 "on account of the ill and mean usage I received from Capt. W. Brown and his Officers." Prince Lee Boo was often used to take soundings ahead of Butterworth. She was loaned to Captain George Vancouver for this purpose in Queen Charlotte Sound in 1793.

The squadron did not procure many furs on their first visit to the Northwest Coast. They wintered in the Hawaiian Islands and returned early the next year, in the Spring 1793. They had better success the 2nd year, and at the end of Autumn, Captain Brown dispatched Butterworth to return to England around Cape Horn, picking up the sealing party he had left there, with the seal skins they were expected to have procured. Brown then sailed in to Canton in Prince Lee Boo with all the furs collected by the three ships. According to Capt. George Vancouver, both Jackal and Prince Lee Boo made this voyage to Canton.

Hawaii The Butterworth squadron first wintered at the Hawaiian Islands in February 1793, when control of the Islands was divided between Kamehameha who controlled Hawaiʻi and much of Maui, and Kahekili who controlled the islands west of Maui including Oahu and Kauai. Brown traded in weapons with both Kamehameha and Kahekili, but strongly favored the latter. In particular he entered into a contract with Kahekili giving Brown the title to the island of Oahu together with four islands to windward in return for weapons and military assistance, suppressing a revolt on Kauai. James Coleman, a seaman left in Niʻihau by Captain Kendrick who had later joined Kehikili's forces, was given stewardship of the land for Capt. Brown and authority over foreign trade during Brown's absence.Menzies, Archibald. Hawaii Nei 128 Years Ago. Honolulu 1920 Although the exact date is in question, it was probably during this period of alliance with Kahekili that the Butterworth squadron became the first European vessels allowed to enter the inner Honolulu Harbor. By Hawaiian tradition, this contract would have ended upon Kahekili's death in 1794

Battle of Kukiʻiahu Jackal and Prince Lee Boo returned to Oahu on 21 November 1794 to find a different situation from the one they had left. On the death of Kahekili, his son Kalanikūpule had succeeded him as ruler of Oʻahu, and Kahekili's half-brother Kaʻeokulani, who had retained command of the Maui group of islands, was invading Oʻahu. This war became known as Kuki'iahu and was fought from November 16 until December 12, 1794.

When Jackal and Prince Lee Boo arrived at Honolulu, Kalanikūpule requested their assistance in the battle. In return Brown was to receive 400 hogs, and according to some accounts, authority over the island of Oʻahu. Eight men under the command of George Lamport, mate of the Jackal, joined Kalanikūpule's forces in a series of battles ashore while Captain Brown and the remaining crew defended the shoreline from the Jackal and Prince Lee Boo.

Jackall fires on Lady Washington

On December 3, 1794, during the conflict, the American snow Lady Washington arrived in Pearl Harbor where she was "met with a friendly reception by Capt. Brown." On December 6, a battle was fought, Kalanikūpule was victorious.

The accounts differ as to what next happened. According to Captain Bishop of the British ship Ruby, Kalanikūpule "came off and did homage to Brown as before, and at his return was saluted by one of the vessels, one of the guns happened to be shotted, which pierced the cabin of the American sloop [sic] and killed poor Kendrick at his table."
