King Louis XI immediately adjudicated his territories to be recovered fiefs of the French Kingdom and campaigned in the Counties of Artois, Flanders and Hainaut and the Duchy of Burgundy.
Among the troops was a sizable contingent of Swiss soldiers, which had been a part of the victorious army of Lorraine, and its salient characteristic was its method of fighting.
Formed up in pike squares, the Swiss mercenaries made themselves and their method of warfare felt far beyond their borders.
[3] Initially, it was Philip of Cleves, who was Mary of Burgundy's cousin and Maximilian's right-hand man, who commanded the cavalry.
[8][9][10] As the battle started, Lord des Cordes forced back the knights within the left infantry square and also captured the Burgundian artillery drawn up on that flank.
After a long duration of indecisive fighting, the Burgundian side launched a counter-attack, which forced the French to retreat at 8:00 p.m. towards Hesdin.
The writings of de But and others make a point that the pikemen were the primary factor in the repulse of the French attack, with Maximilian's personal bravery playing a notable role.
[11][12] Benecke and Querengässer note that Maximilian incorporated Hussite War tactics, with the use of wagon forts, into the battle.
[2] Despite winning, Maximilian had to abandon the siege of Thérouanne and disband his army either because the Netherlanders did not want him to become too strong or because his treasury was empty.
[15] According to the Belgian historian Jelle Haemers, after Guinegate, the war against France was no longer defensive in nature "but had instead become an offensive drive to recapture territory lost in 1477."
Meanwhile, trying to avoid another direct military confrontation, Louis XI adopted a broader strategy in encouraging the Burgundians' internal opponents, which successfully forced Maximilian to split his forces in different directions, abandon plans to recapture territories and search for new allies.
