The militia leadership in the camp at first thought the early skirmishing was a typical morning salute, and paid it little heed. Shortly after reveille, the severity of the alarm became apparent. While the camp mobilized, a militia company numbering about sixty prepared for the British advance behind the earthworks. They carefully withheld fire until the grenadiers, advancing with bayonets fixed, were within , and then unleashed a torrent of fire on the British column. Fordyce, leading the column, went down in a hail of musket fire just steps from the earthworks along with many of the men in the front ranks. The British advance dissolved as the militia musket fire continued; about half of Fordyce's force was killed, and many were injured. The navy gunners provided covering fire as they retreated back across the bridge, but their small cannons made no impression on the earthworks.
