Divide and Conquer is the third scenario of the Tariq ibn Ziyad campaign in Age of Empires II HD: The African Kingdoms. After conquering much of central Iberian Peninsula, Tariq ibn Ziyad and Musa ibn Nusayr decide to divide their armies and venture further north and capture the cities of Zaragoza and Narbonne.
- Theodemir of Murcia (Goths): Theodemir of Murcia, a Visigothic General, has pledged allegiance to the forces of Tariq and Musa. He has a well fortified base with lots of infantry and a navy. His base is directly south of the player's eastern base and will periodically send the player tributes of gold and some of his soldiers, mainly Champions and Elite Huskarls. He also has a Market and a Dock, which can be used to trade, though it won't make a lot of gold since his base is so close to the player's own base.
- Locals (Goths): The Locals have their base on a small islands across the Balearic Sea, on the eastern edge of the map. They do not play any major role in this scenario except that their island has a lot of gold mines and upon approaching them, they will let the player use their Mining Camp. They also have a Relic on their island which can be carried back and kept in the player's Monastery. Their Market, located northwest of Narbonne's base, will be used by Narbonne to trade and produce gold.
- Kingdom of Asturias (Goths): They are a group of soldiers who have formed a resistance and are being led by Pelayo of Asturias, a Visigoth nobleman. They have four bases spread across the northern and western sides of the map which separate the two main bases of the player. Each of their base is well fortified, with a Castle, Fortified Walls and quite a few soldiers and siege weapons. They also hold a Relic in a Monastery in each of their four bases. It is not compulsory to defeat them to win, but they will prove to be a big annoyance, especially in the western base of the player if they are not attacked.
- Zaragoza (Spanish): Their city is located at the center of the map and is built on both sides of the Erbo River. Their city is well fortified, with a Castle and three special towers called 'The Tower of Flies' which are stronger than regular Watch Towers and have hitpoint regeneration, but have a smaller range. They will generally train Knights, Light Cavalry, Pikemen and Skirmishers. They also have a smaller base to the east of their city, which has two Docks and a few soldiers guarding it. They will use these Docks to produce a powerful navy and attack the player's Docks and harass their Fishing Ships, if they try to fish.
- Narbonne (Goths): They have their city at the north-eastern edge of the map, along the coast of the Balearic Sea. Like Zaragoza, their base is also well fortified, along with a powerful navy. They have a large army in their base, comprising of Long Swordsmen, Elite Huskarls, Scorpions and Battering Rams. They will also use their Galleons and Fire Ships to harass the player's Fishing Ships and attack the player's Docks, along with Zaragoza.
The objective of the scenario is to destroy the Castles of Zaragoza and Narbonne. The player starts with two separate bases – one on the western edge of the map and another one south of Zaragoza. Both bases have their own economic value – the western base has a lot of gold and stone, while the eastern base has lots of trees nearby and is the player’s only access to the Balearic Sea and all the fish in it. Thus, all the Villagers in the western base should be put on gold and stone, while those in the eastern base should cut wood and make farms.
Fishing in the sea will be dangerous, since there are two powerful enemy navies to be careful of. Thus, the player should make Galleys first to ward off enemy ships. Once the player has around 10 Galleys, they can start making Fishing Ships. Don’t forget to upgrade them to War Galleys and use them to protect the Fishing Ships, immediately replacing the ones that are damaged or destroyed. Since Narbonne is more aggressive at the waters, one strategy is to use Demolition Ships to destroy their Docks to end their harassment. Destroy Zaragoza's docks too for a safe trading and fishing environment.
Narbonne will be the first one to strike. They will attack the eastern base after approximately 10-15 in-game minutes. The player should use the initial army to ward off these attacks. Theodemir of Murcia will periodically give the player Elite Huskarls and Champions, so the player does not need to make many troops of their own. It would be good to make one or two Monks to heal the injured soldiers so they can be used for longer.
Over at the Western base, Kingdom of Asturias will begin attacking the player with Elite Huskarls, Scorpions and Halberdiers. Once the player has collected enough stone, they should immediately construct a Castle outside their base to defend it. Then start making Knights because the player’s initial army will not last long. Make sure to only use the Knights to defend the western base and not to attack their base because the player doesn’t need to waste resources and time attacking the Kingdom of Asturia (though the player can attack them if they are proving too much of an annoyance).
By this time, the player should start to advance to the Imperial Age if they have enough resources. It will be difficult to manage both bases, but do not forget to go back to the eastern base to see if the enemies are attacking there. It would also be a good idea to build a Castle outside the eastern base as well to help defend it.
Once the player has reached Imperial Age, go over to the eastern base and start making Trebuchets at the Castle. At least 5-6 Trebuchets are needed so that they can one-strike most buildings. Build five or six Stables near the Castle and queue up Knights, and use one of them to upgrade Knights to Cavaliers. Then, take the entire army to Zaragoza and use the Trebuchets to open a hole in the wall. Use the army to protect the Trebuchets and aim for the Stables, Archery Ranges, and Siege Workshops. All the while, keep queuing up Cavaliers at the Stables and bring them to help the rest of the army. Eventually, the Trebuchets will take down Zaragoza’s castle. It should be noted that Zaragoza will not surrender even if their Castle is destroyed and they must be defeated by destroying their buildings and killing their units.
Once Zaragoza is defeated, train more Cavaliers and Trebuchets and take the fight to Narbonne. Bring all the soldiers from both bases since the player doesn’t need the bases anymore. Open a hole in the wall, bring in the Cavaliers to protect the Trebuchets and attack the military buildings, while the Trebuchets attack the Castle. In case the player’s soldiers die, keep Cavaliers queued up in the Stables back at the base. Eventually, Narbonne will be overpowered and their Castle will go down. Once their Castle is destroyed, the player is victorious.
