The Battle of the Dunes, also known as the Battle of Dunkirk, took place on 14 June 1658, near the strategic port of Dunkirk in what was then the Spanish Netherlands. Part of the Franco-Spanish War and concurrent Anglo-Spanish War, a French army under Turenne, supported by troops from the Commonwealth of England, had besieged Dunkirk. Led by John of Austria the Younger and Louis, Grand Condé, a Spanish force supported by English Royalists and French Fronde rebels attempted to raise the siege but suffered a severe defeat.

Charles II was King of Scotland from 1649 until 1651 and King of England, Scotland, and Ireland from the 1660 Restoration of the monarchy until his death in 1685.
