[1][2] Thirteen days later, on March 20, Héraugière, unable to keep the defense, agreed to terms of capitulation between the Protestant forces and the Spaniards.

[4] The Spanish forces were composed of two Spanish tercios led by Don Luis de Velasco and Don Antonio de Zúñiga, two German regiments, three Walloon regiments, and some pieces of artillery.

[5] The majority of the Protestant forces were composed of Dutch troops, about 1,800 infantry and cavalry, which included a regiment of Scots commanded by General Barthold Balfour, and a contingent of Huguenots.

[3][6] Although Huy was declared neutral in the war during the occupation by the forces of Héraugière, the population endured great abuses by the Protestant soldiers.

[5] The occupation of Huy by the United Provinces, and consequently the violation of the rights of neutral zones, was the failure of a plan by Philip of Nassau for control of an advantageous position from which to open a short route and aid the operations of the French troops commanded by the Duke of Bouillon in the borders of Luxembourg.
