Battle of Mookerheyde

The Battle of Mookerheyde was a battle of the Eighty Years' War fought on 14 April 1574 near the village Mook and the river Meuse. In the winter months of on 1574, William the Silent's brothers, Louis and Henry of Nassau, raised a mercenary army in Germany of 6500 infantry and 3000 cavalry, and led them towards the city of Maastricht, where they were to met the Prince of Orange named William the Silent who led 6000 Dutchmen himself. After that, they would join forces and march for the relief of Leiden which was besieged by a large Spanish force under the Duke of Alba. Along the march over a thousand men deserted, seven hundred were killed in a night attack by the Spanish, and the rest were mutinous for their pay, which they had not received due to the Prince's empty coffers.

Finally, after crossing the Meuse River, before having joined armies with William the Prince of Orange, Count Louis with only 5,500 infantry and 2,600 cavalry encountered Alba who had temporarily lifted the Siege of Leiden and marched with 5,000 infantry and 800 cavalry to oppose Louis' march. This army was led by Sancho d'Avila and Bernardino de Mendoza. Near the village of Mook, the two armies met. At first, the cavalry of the Dutch triumphed over the Spanish cavalry, and the Dutch infantry fired several salvos into the Spanish ranks, but the Spanish infantry were well-trained and in time defeated their adversaries.

In the end, the Dutch suffered a disastrous defeat, losing at least 3,000 men with both Louis and Henry killed. Soon after, the rebel army dispersed due to lack of pay.

Then, Alba resumed the siege of Leiden, which finally terminated in the Dutch favour.
