The siege of Sluis (1604), also known as the Sluis campaign or the Battle of the Oostburg Line, was a series of military actions that took place during the Eighty Years' War and the Anglo–Spanish War from 19 May to 19 August 1604. A States and English army under Prince Maurice of Orange and Horace Vere respectively crossed the Scheldt estuary and advanced on land taking Cadzand, Aardenburg, and IJzendijke in the Spanish Netherlands. This soon led to the culmination of the siege of the Spanish-held inland port of Sluis.
