With Innsbruck fully under Berengar's control and the walls intact, the young Viscount rapidly mounted his cannons on the best positions of the city walls. Unlike the walls of Kufstein, which were expertly designed to prevent any blind spots, the medieval walls of Innsbruck did not allow for proper coverage.
Especially with as few as 15 field guns, considering he left three of his cannons behind in Schwaz, he was limited in his use of artillery, but that did not matter, the hundreds of rifled muskets among his troops, could make up for the lack of defensive artillery. As for the remaining smoothbore muskets, they could be placed through the machicolations and effectively counter enemy troops who got too close to the walls.
