Age of Empires Series Wiki

The Siege of Alesia (Alesia in the original) is the third scenario of the Ave Caesar campaign in Age of Empires: The Rise of Rome. Caesar and his Romans must fight their way through the Gauls and kill Vercingetorix.

Scenario instructions[]


Gaul has risen in revolt. You have isolated the great Gallic leader Vercingetorix with only a portion of his forces and driven him into the hilltop fortress at Alesia. He is surrounded, but another great Gallic army is gathering outside your fortifications to free him. Kill the great Gallic leader while avoiding the destruction of your army by the forces inside and outside your fortifications.

Starting conditions[]


  • Kill the Gallic leader Vercingetorix. If Caesar dies, the mission will be lost.


  • Complete your fortress as quickly as possible.
  • Avoid a multi-front siege from the enemy at all costs.



  • Player (Romans): The player starts with a double-ring fortress (including numerous Sentry Towers) in the center of the map. It entraps the red Gaul base and Vercingetorix. The outer walls on the western side are unfinished, however. Furthermore, the resources are low and located far away from the player's Town Center (which is located in the south-east of the base), there are no buildings besides the mentioned and some Houses, and the player's starting force is small.


  • Gaul (Assyrians): The red Gaul are entrapped inside the player's base and attack with cavalry and infantry.
  • Gaul (Assyrians): The yellow Gaul start in the western corner of the map and attack with cavalry and infantry.
  • Vercingetorix (Greeks): Vercingetorix is behind walls inside the red Gaul base and guarded by Heavy Horse Archers and Catapults.
  • Gaul (Assyrians): The orange Gaul start in the eastern corner of the map and attack with Bowmen and Stone Throwers.


Two of the Gauls are outside of your town, and the game suggests that you finish your walls. On the other hand, the outside bases are so small, there is no reason why shouldn't finish the Gauls instead, with your starting army, rather than wasting the stone - so do that. Send your hero, your Legions, and your archers to a base, kill the Villagers and destroy the Town Center, then do the same to the other town.

Now, most of the map belongs to you, and the remaining Gauls are heavily walled in, so you can take your time, if you want to.

Vercingetorix is in a walled-off area at the center of the Gaul camp, so destroy the Towers around him with a Catapult. If you set the Catapult to attacking ground, you can finish off the Horse Archers protecting him, too - they won't think of moving out of the way of the shot if you attack ground.

Since Vercingetorix can't attack at range, and can't get through his own walls, any ranged unit can finish him off at absolutely no risk - you can use your initial archers, if they are still alive, or train a Ballista.


Historical notes[]

Nearly all of Gaul rose in revolt, beginning in 54 BC. The Gauls realized that they had been conquered by a force they outnumbered 20 to 1. In central Gaul, Vercingetorix, the ablest of the Gallic leaders, gathered a huge army. He conducted a skilled campaign and had Caesar retreating with his legions. During the retreat Caesar seized the initiative, as was his wont, and drove Vercingetorix into the hill fortress of Alesia. Building a double fortified enclosure to keep Vercingetorix in and the Gallic relief force out, Caesar fought a masterful battle. The Gallic leader surrendered to save his people from further disaster and was strangled eventually in Rome. The Gallic rebellion was quickly extinguished and Gaul went on to remain a key part of the Roman Empire for the next 500 years.

With the defeat of Vercingetorix and the Gauls, you have brought to a close almost nine years of constant fighting. Nearly 800 towns have been taken (in what later will become France and Switzerland). The very name "Caesar" will become synonymous with leadership. Such success is not without price, however. Jealous of your power and celebrity, and concerned about the size of your army, enemies are gathering in Rome. With all of Western Europe at your feet, it is time to return home.
—In-game section


Your failure to put down the revolt in Gaul means that these Celtic hordes will continue to raid southward. In addition, enemies are appearing within the walls of Rome. It is time to return home. Don't expect a pleasant reception, however, having left such a powerful force of barbarians leering down at Rome over the Alps. Report to the Tiber River for duty as a sandbag.
