Battle for Middle Earth - Evil Campaign - Rohan

Battle for Middle Earth - Evil Campaign Map - Rohan (+50 Command)
This is a hint/walkthrough post for Battle for Middle Earth. You can find an index of all our Battle for Middle Earth posts here.

By now you should have several units of Pikemen or mixed Pikemen Hordes. This mission is remarkably easy with six units of Pikemen-Crossbowmen:
Rush the Rohan fortress in the northwest at the very start. About mid-way across the map, you will probably encounter Rohirrim finishing up a troll lair. Charge right through and you could possibly score as many as three chests of treasure (resources).
Since the Rohirrim can't really do anything to your Pikemen, keep going until you reach the city gates.
The enemy does not have perimeter towers that shoot at you, so park two units at the front gate, and two at each of the sides, blocking the Postern doors that let units out through the walls.

This technique of rushing Rohan castles and boxing them tends to work well, but couldn't really be done prior to Pikemen because of Rohirrim tramples.

The nearby Building Sites are probably occupied by Farms. Destroy them and build something on them. If you have at this point moved quickly enough, they will not have any other Farms on the map, and can't harrass you with Peasants.

When the Rohan reinforcements arrive after the countdown, they come from behind those Building Sites and aren't as threatening as they could be if they were allowed to merge and descend on your base. When they see your building on the Building Site, they will stop to attack it. Charge them and destroy them with Pikemen.

By now you should have an excessive amount of Resources from your base and maybe had time to fully upgrade all your troops. Bring up Ballistae and tear down the front gate and some adjacent wall sections. Pour your troops in to clear the base and win the map.

After the initial Rohan reinforcements, it is probably safe to secure the city with just 3-4 units, as long as you cover three sides (gate, north wall, south wall). The others can roam the map, but there isn't anything special to do except the Bonus objective of putting a garrison in the Ruined Towers.
