The paper, published in the journal History and Technology, traces how Cort learned of the Jamaican ironworks from a visiting cousin, a West Indies ship’s master who regularly transported “prizes” – vessels, cargo and equipment seized through military action – from Jamaica to England. Just months later, the British government placed Jamaica under military law and ordered the ironworks to be destroyed, claiming it could be used by rebels to convert scrap metal into weapons to overthrow colonial rule.

“The story here is Britain closing down, through military force, competition,” said Bulstrode.

The machinery was acquired by Cort and shipped to Portsmouth, where he patented the innovation. Five years later, Cort was discovered to have embezzled vast sums from navy wages and the patents were confiscated and made public, allowing widespread adoption in British ironworks.
