In overlord 2 how do you stand up the siege tower?

In Overlord II, to stand up the siege tower, you need to control your minions and direct them to the tower's base. Once there, use the command to have them lift the tower into an upright position. This action typically requires a sufficient number of minions to accomplish, so make sure to gather enough before attempting. After the tower is properly positioned, you can proceed with your assault on the enemy fortifications.
