The reason that the positioning of cities is so important when you fight other alliances is that you don't want to give them the chance stack defense in their cities.

Now, if you consider that defenders already have city walls and towers which, when fully built, will give defenders 151,9% defensive bonus over the attacks, this means that you don't want to fight more defensive troops than you have to. However, if the defenders had ten times those numbers (that is, 5000 swordsmen and 5000 archers), they would be 45% more efficient. If 2000 slingers attack a defense with 500 swordsmen and 500 archers, the defense will not be particularly effective. Investing in these skills will provide you with more strategic options during a siege.When you defend, you have the advantage of being able to stack your units and gain advantage in numbers. The Progression Siege Specialization and Siege Masters empire skills can increase the number of Siege Projects that an empire can use simultaneously. Incorporating these units into your army will greatly enhance your ability to capture cities. Units with the Siege Breaker attribute can increase the rate of Fortification damage during a siege. Start of Battle Effects: Additional wall breaches Start of Battle Effects: Half of the defender’s tower units are destroyed Start of Battle Effects: Defender’s units take 20 points of Physical Damage Start of Battle Effects: Attacker starts with 2 Onager units Start of Battle Effects: Attacker’s units take 20 points of Physical Damage

Here is a list of Siege Projects and their respective effects: Each empire can utilize two Siege Projects simultaneously, and this number can be increased with the Progression Siege Specialization and Siege Masters empire skills. They provide various bonuses and advantages, such as dealing additional damage to Fortification or affecting unit performance. Siege Projects are critical tools for both the attacker and defender during a siege. Fortification is reduced by 10 points each turn, and this rate can be increased using Siege Projects or units with the Siege Breaker attribute.

The primary goal of the attacker is to reduce the city’s Fortification to 0, which allows them to launch a siege battle. When a city is attacked, a siege takes place.
