A complex political situation resulted in both French and English forces fighting for both sides. When the government of Louis XIV formed an alliance with Lord Protector Oliver Cromwell, the exiled Charles II of England allied himself with Philip IV of Spain. Charles set up his headquarters in Bruges. The Spanish supplied only enough money to form five regiments. This was a disappointment for the Royalists, who had hoped to be able to form an army large enough to contemplate an invasion of the English Commonwealth. A renewal of a 1657 treaty between Cromwell and Louis XIV provided 6,000 Commonwealth infantry and a fleet to aid Turenne. Along with English forces, French forces fought on both sides with Condé, a French Prince of the blood, leading a contingent of French rebels of the Fronde.
