Battle of Baesweiler

The Battle of Baesweiler (22 August 1371) was a conflict between the duke of Luxembourg-Brabant and the Duke of Jülich.

Background
Attacks on Brabant's commercial interests in the territory of the Duke of Jülich had almost caused war in November 1367 and September 1369. Peace was only maintained by the involvement of the Landfrieden. After mercenaries robbed a number of Brabantine merchants on the territory of William II, Duke of Jülich in 1371, William refused to pay reparation to Wenceslaus I of Luxembourg, the Duke of Brabant, let alone punish the mercenaries, instead protecting them and even hiring some. As Wenceslas prepared his forces, William sought help from his brother-in-law, Edward, Duke of Guelders.

Battle
On 20 August, Wenceslas led his army of 2,500 from the border town of Maastricht towards the enemy capital of Jülich. The army advanced slowly, burning and looting as it went and by the evening of 21 August was encamped near the town of Baesweiler north of Aachen. On 22 August, Wenceslas' army was confronted by the smaller force of William, Duke of Jülich which consisted of 1,600 troops. Two different versions of what happened next are recorded. In one, the army of Jülich attacked in the morning while the Brabant forces were at mass. In the other, the army of Brabant had the best of the fighting until the late appearance of the troops of Edward, Duke of Guelders, perhaps from ambush.

The battle ended with the capture of the Wenceslas, Duke of Brabant, and William, Margrave of Namur, and the death of the Edward of Guelders. Guy I of Luxembourg, Count of Ligny, a distant relative of the Wenceslas, was also killed. Wenceslas was incarcerated at Nideggen at Roer.
