The American Revolutionary War turned Nantucket’s dependence on whaling into a problem of divided loyalties and interrupted commerce. The island’s fleet, once sustained by family enterprise and increasingly long voyages, fell from 150 ships to 35 as Nantucketers tried to remain loyal to Britain, their greatest customer. The war did not end the trade: it forced an industry built around movement across the sea to find new routes, markets and places to operate.

An island economy at risk

Nantucket whaling began as a family business, passed from one generation to the next. A promising young man might expect to captain his own ship after two voyages, and crews could include sons and relations of the island’s most respected families. The work carried both economic necessity and the prospect of distinction. Before the war, shipboard try-works had already changed the scale of the enterprise. Introduced by 1750, the brick ovens and great cauldrons let crews render blubber at sea rather than return with whole whales to port. Processing the catch aboard ship made the longer voyages needed to find whales practicable; it also tied Nantucket more closely to distant waters and overseas buyers.

That expansion left the trade exposed when war disrupted access to its principal market. Nantucket’s whaling fleet declined from 150 ships to 35 while the island tried to preserve its ties to Britain. The reversal was not simply a loss of vessels: it struck at a commercial system whose crews, voyages and returns depended on sustaining movement between whaling grounds and buyers.

Neutrality under pressure

Nantucket was officially neutral, a position connected to the pacifism of its inhabitants, but neutrality offered no easy freedom to trade. Whalers could sail from New England only if they declared for the rebels; if they did, the British would claim their ships. The islanders faced a choice in which either course could jeopardize their vessels or their commercial relationships. Their pacifist commitments and their dependence on British trade pulled in different directions, while the fleet bore the consequences.

Some whalers responded by moving beyond the immediate contest. They relocated to Newfoundland or Canada to continue their work; others sailed to the Falkland Islands to exploit newly discovered whaling grounds on behalf of Britain. The trade’s geography shifted under pressure: ships and experience were redirected rather than simply abandoned, carrying Nantucket’s whaling operation into other jurisdictions and waters.

Wartime trade and divided loyalties

The island’s neutral position did not prevent every form of commerce with Britain. Kezia Coffin, a Nantucket merchant whose business had expanded from selling pins into whale products, made a private arrangement with a British admiral during the Revolution. She shipped oil and candles to London alongside smuggled goods sold at inflated prices. Her enterprise shows how wartime restrictions could make commercial opportunity depend on private negotiation and concealed cargo as well as on the movement of whaling ships.

Her trade also points to the products at stake. Nantucket’s whaling economy did not end at the capture of a whale: its materials were processed into goods, including oil and candles, that could be shipped to distant markets. The war placed that commodity network under strain, but Coffin’s arrangement demonstrates that connections with Britain continued through discreet, profitable channels even as the island’s fleet contracted.

Recovery and the export of whaling

After the Revolution, Nantucket grew richer than ever from the wealth of whales, and its trade and expertise spread beyond the island. Nantucket Quakers established a whaling port at Hudson, New York, more than 120 miles from the sea, where a fleet of 35 ships nevertheless prospered. Other settlements followed at Dartmouth, Nova Scotia. These ventures made the industry less exclusively local: people and knowledge from Nantucket helped create whaling stations elsewhere.

The effort to establish a port in Britain illustrates both the reach of this postwar expansion and its bargaining over terms. In 1785, Starbuck, Folger and a member of the Rotch family approached Britain about creating a whaling port. A Rotch representative and his son Benjamin travelled to London to negotiate with Prime Minister William Pitt. The proposed terms included £20,000 in removal costs and naturalization for 30 ships and 500 Nantucketers. While negotiations continued, however, the Rotch family established itself at Dunkirk after receiving a better offer from France. Britain eventually invited the Nantucketers to set up a station at Milford Haven in 1792, granting them the rights and privileges of natural-born subjects. The resulting settlement included New England-style buildings, a Quaker meeting house and a Pembrokeshire cemetery whose names—Starbucks and Folgers—recorded the movement of Nantucket families across the Atlantic.

The war’s significance for Nantucket was therefore not only the immediate collapse in fleet numbers. It exposed the vulnerability of a maritime economy tied to foreign markets, while prompting routes and settlements that carried its business abroad. The subsequent recovery transformed disruption into outward expansion: Nantucket’s whalers returned in greater numbers, and their trade took root in new ports.
