Predating this siege was the claim by Maximillian on territories in old Bayern, including the cities Kufstein, Rattenberg and Kitzbühel from the Wittelsbacher family. Kufstein was the property of the Penntzenawer family who reluctantly gave up Kufstein in June 1504 with their new instatement by Maximilian as caretaker of the city they once owned. After an oath, securing the allegiance from Penntzenawer, the city was left in their care and fortified with new artillery from Innsbruck. In August they rebelled and turned back to their former party, the Wittelsbacher family.
At the beginning of the siege Maximilian had 24 cannons to shoot the heavy and high walls of Kufstein from the Zellerberg. They first fired three warning shots after which Kufstein would have to capitulate or endure the bombardment of all the cannons. At first the small cannons could not penetrate the walls of Kufstein. After this Maximilian ordered the heaviest cannons from Innsbruck.
