Empire Earth II/Defending the Order

Here is a very classical RTS mission: you start out with most of the map under you control, but a huge attack will capture all your villages, until you are left with the capital of the Teutonic Order, Marienburg.

During the first part of the mission, you will have to gather as much resources as possible before Elbing, Liebstadt and Holland fall. During the second part of the mission, you will have to protect Marienburg and the Master of the Order against waves and waves of attackers, until the Polish King Jagello shows up. The mission is completed when this fellow dies.

Even after your three villages have fallen, you will still receive resources, between each wave of attackers. In any case, if you play in Normal difficulty and do not screw up too badly, you will have more than enough troops to win this scenario.

Walkthrough
As soon as the game starts, make a dozen citizens in each of your three villages. Since you won't be able to harvest Stone, Iron and Tin for long, the more you get now, the better. There are two Iron nods in Elbing, two Stone nods in Liebstadt and two Tin nods in Holland. Additionnaly, build six farms or so around your City Center in Marienburg, and order a couple more citizens to cut down the forest that is within the walls of the fortress. While you're at it, hire a couple Teutonic Knights in Marienburg (20 will suffice), and chain produce Crossbowmen and Balistas (as long as your resources allow it).

Your villages will be lightly attacked. Use your local troops to protect your peasants. If you keep them alive, you will quickly fulfill the three secondary objectives. You'll be rewarded with Teutonic Crusaders and some more resources each time. Move the Crusaders to Marienburg.

After a couple minutes, Elbing is going to be attacked by a huge army. There's no point trying to defend the village. Take the survivors if there's any, and move them to Marienburg. When your City Center is captured, do the same with the units left in Liebstadt and Holland. You can take the citizens and garrison them into Towers or Fortresses.

From now on, you have a couple more minutes before the Polish army moves toward Marienburg. Take the trebuchets defending the Palisade and bring them behind the Walls of Marienburg. The Palisade will fall quickly, leaving your trebuchets unprotected. Build as many Towers as possible on your Wall section, and spend the resources you have. Upgrade Teutonic Knights, Crossbowmen, Trebuchets. Garrison Pikemen into your towers, and build one or two Fortresses right behind your walls (on in the middle of the section, another one near the northernmost gate).

Before the Polish army attacks, you will receive a message: Polish Cannons are going to attack the Castle from the North. When notified of this, take your Crusaders and bring them onto the island North of Marienburg. Look out for the Cannons and convert them (after killing the defenders). If you act quickly, you will have enough time to bring them into Marienburg before the Polish main attack starts. In any case, the first attack is easy to repel. Use your Knights to destroy the many Trebuchets, then destroy the remaining troops.

When the first wave is defeated, two things happen. First, you get some reinforcement, as a Cargo Ship disembarks troops on the island up North (they bring a few resources too). Secondly, you receive another objective: kill 250 Polish troops.

If you managed to convert the four Bombard Cannons, the rest of the missions is a walk in the park, as they will quickly dispose of anything approaching your Walls. Otherwise, you will have to micromanage a bit more. Use your Knights to destroy any siege weapon approaching, and your Crossbowmen to kill enemy units. After each wave of attackers, you receive a bit more resources and reinforcements. As long as possible, try to spare your Crusaders for the last attack: make them convert enemy units from afar, but don't throw them in the melee.

After you have killed roughly 200 enemy units, the Polish will launch a final attack against your Castle. Nothing daunting, though it is a bit more important than the previous ones. Once this attack is successfully defeated, you receive your last objective: killing the enemy leader, Prince Jagello.

Nothing extraordinary here: Jagello will run toward your Castle with his escort, will his army launch a final full-scale attack. Do not bother about the Polish army, and focus on Jagello and his escort. If you have artillery left, he will die in a few seconds. If not, try to kill him with long-range units and Towers, as he will stun any surrounding unit.

Tips

 * The most important trick in this level is to convert the four Bombard Cannons that will attack the Castle early on. If you successfully do it, you can win single-handed.
 * Obviously, do not bother building anything in the three villages that are going to be destroyed. You only need to hire citizens there.
 * You can sell exchange Food and Wood for Gold, Iron or Tin at the Market.
 * As long as it is possible, repair your fortifications between each attack.
