The imperial besiegers of Crema had set in their final positions in the October 1159; starting from the following December, they use a "cat" (a mobile roof), followed by a siege tower, to cover their siege engineers who are mining under the walls.
This leads to the Cremaschi also digging tunnels to start underground warfare.
