The Battle of Süntel was a skirmish in 782 between Saxon rebels led by Widukind and a detachment of Frankish forces led by envoys of Charlemagne. The result was a victory for the Saxons, resulting in the deaths of four counts, 20 other noblemen, and two of the three leaders of the Frankish detachment. Shortly following the loss, Charlemagne had 4,500 rebels beheaded on a single day, in an event sometimes known as the Verden Massacre.
