The Merchant Who Waged War at Sea
About Elias Hasket Derby
Elias Hasket Derby never went to sea himself. He was a counting-house man, a merchant who understood ledgers and markets and risk. But from his wharf on Salem harbor, he waged a private war against the British Empire that was, by some measures, more effective than the Continental Navy.
Derby had inherited wealth and expanded it through the cod and sugar trades. When war came, he saw clearly what many merchants feared to acknowledge: the old trading relationships were finished. The question was whether to wait out the disruption or make the war itself profitable.
He chose to fight — with capital. Derby outfitted privateers, hiring experienced captains and arming merchant vessels with cannon. Each voyage was a gamble: a privateer could return with a prize worth tens of thousands of pounds, or it could be captured, the crew imprisoned, the investment lost.
Over the war years, Derby's ships captured British vessels carrying everything from rum to military supplies. The prizes were brought to Salem, their cargoes auctioned, the proceeds split between owner, captain, and crew. Sailors who might have earned modest wages on merchant voyages could make a year's income from a single successful cruise.
By war's end, Derby was arguably the wealthiest man in America. His fortune was built on risk, not plunder — though the distinction was sometimes academic. He had gambled everything on independence, and independence had paid.
The Peabody Essex Museum in Salem today holds Derby family papers that document these operations in meticulous detail. The ledgers tell a story of war as business and business as war.
