Sieges | Battles Heroes VII Guide

The second battle type in which you will participate is siege. A siege occurs when the battle takes place in a city, fort or garrison. The main difference between sieges and regular battles is additional elements appearing on the battle map. Most of all, there are city walls that separate two armies. In order to destroy them, the attackers have a siege machine that is destroying a part of the wall during each turn. After hitting 2-3 times in the same place the wall is falling and the units are able to get through it. By default, you cannot control the siege machine. It selects the attacked wall fragment randomly. You can change it with the Siege Warfare ability from the Warfare tree. Not only will it allow you to attack twice, but you will also be able to select place that you intend to destroy.

Battles for cities are harder than regular ones. Remember that before deciding to attack.

There are always gates in the walls. They can be used by the defenders to leave the walls and counterattack. In order to get through the gate, the attacking army must first destroy it. Additional elements that appear only during sieges are guard towers, from one to even three. During each turn they deal rather large damage to attacking forces, they also cannot be destroyed by siege machines.

The tactic you use should mostly depend on whether you are attacking or defending. In case of attack, you don't have many options, you must patiently wait for a break in the wall and attack with your ranged units. In case of defense, you must consider two things - the number of allied ranged units and the number of enemy ranged units. If enemy has advantage in ranged units, then it is pointless to hide behind the walls and lose your forces. In such case, you must get outside the walls and attack the enemy directly. If you have more ranged firepower, then it is better to remain behind the safe walls and attack enemy units until they get through the walls.
