James Barrett mustered 400 Patriot militiamen in front of his farm, guarding a bridge and two banks of the Assabet River, while facing four companies of British regulars under Major John Pitcairn. The militiamen's volleys took down whole British contingents, as they were ordered to fire before the British deployed in their firing lines. The British were defeated, with 130 killed.
