In the Battle of Ingolstadt, in May 1525, the Black Company found itself alone against the forces of the Swabian League after its allies had been destroyed. The Black Company fought its way back to Ingolstadt and occupied the ruins of the castle, the main buildings of which the members of the Company had themselves burned down some months before. The troops of the League encircled the castle and started their attack. The castle's occupants fought off two assaults but during the third attack, and after the League's heavy artillery breached the massive walls, they were killed.
