DUNES,[1] or Dunkirk Dunes, Battle of, was fought near Dunkirk on the 24th of May (3rd of June) 1658, between the French and English army under the command of Marshal Turenne and the Spanish army under Don Juan of Austria and the prince of Condé. The severest part of the fighting was borne by the English contingents on either side. Six thousand English infantry under General Lockhart were sent by Cromwell to join the army of Turenne, and several Royalist corps under the command of the duke of York (afterwards James II.) served in the Spanish forces. The object of the Spaniards was to relieve Dunkirk, which Turenne was besieging, and the complete victory of the French and English caused the speedy surrender of the fortress.
