Agnes von der Vierbecke

According to tradition, Agnes agreed to help smuggle Count Dietrich's soldiers into the heavily fortified town of Dortmund on 4 October 1378, the Sunday after Michaelmas.

[5] Hidden in the bushes in front of the gate was young Count Conrad von Dortmund with his armed men, waiting to assist in an attack.

[2][8] When he left, Agnes proceeded to climb up the Wißstrasse Gate tower, and gave a signal with a white handkerchief for the enemy troops to attack.

[4] The elder Count of Dortmund and Agnes' brother, Johann von Wickede, accused the imperial city council of an unjust deed.

A women's history website based in Dortmund claims that there is no evidence in sources as to what exactly Agnes did, but rather that she has been the subject of various tales, poems, and two theater pieces.

[2] Ten years after Agnes' death, Count Engelbert III von der Mark declared that the hasty executions were unjustified.
