Battle of the Mookerheyde

The Battle of the Mookerheyde was a battle during the Dutch war of independence. It took place on April 14, 1574, near the village of Mook and the river Meuse. An army of mercenaries was hired by William the Silent to bring relief to the city of Leiden. This city was under siege by a Spanish army. The Dutch mercenary army led by William's brothers Louis of Nassau and Henry of Nassau, moving north on the east bank of the river Meuse, was met by a Spanish army, led by Sancho d'Avila and Mendoza.

The Spanish army consisted of 5,000 infantry and 800 cavalry, while the Dutch army consisted of 5,500 infantry and 2,600 cavalry. However, most of the mercenaries were not yet paid and were not motivated. Hence, the ensuing battle was a disaster for the Dutch. Part of their army deserted during the action, shouting for money. The Spanish lost only 150 men. The rebels lost 3,000 men; both Louis and Henry were killed.
