The ducal army consisted of the "Black Guard" (4.000 mercenaries from the Netherlands), 2.000 armoured cavaliers and 5.000 commoners. The defenders were about 3.000 men, all of them peasants. After seizing the village of Meldorf the ducal army pursued the peasants into the marsh. There the defenders opened at least one dike sluice in order to flood the land. The peasants knew the countryside and used poles to overleap the ditches. Most of the ducal soldiers were not killed, but drowned.
The farmer Wulf Isebrand was the leader and organiser of the peasants' defence. While he was a real person, the existence of other participants of the battle is not proven. For instance, the legendary Reimer von Wiemerstedt is said to have killed Junker Slentz, the chief of the "Black Guard"; another doubtful participant was the "virgin" Telse.
Many details about the battle were made up later in order to heroize the defenders. In 1900 a pompous monument to the defenders was raised. The cult reached its peak in the Nazi era, when local party members misused the names of the battle participants for their propaganda. Today there is a more neutral museum at the site commemorating the battle.
