Holmes's Bonfire was a raid on the Vlie estuary in the Netherlands, executed by the English Fleet during the Second Anglo-Dutch War on 19 and 20 August 1666 New Style. The attack, named after the commander of the landing force, Rear-Admiral Robert Holmes, was successful in destroying by fire a large merchant fleet of 140 ships. During the same action, the town of West-Terschelling was burnt down, which caused outrage in the Dutch Republic.
