You have to make a choice, select one of the following options:

To build a siege machine, click on one of the blue squares in front of the castle or city. During the construction of the camp it is worth building at least one siege machine - this will definitely make the siege easier.

Remember that other lords are active during this time, so they can come with reinforcements to the attacked town.

When the siege begins, the construction of the camp begins - you will see the Building Siege Camp progress bar on the screen. Siege engines should be built before the attack begins.
