AotR: Weekly Challenge 26 - Re-occupation of Isengard addon - Age of the Ring mod for Battle for Middle-earth II: Rise of the Witch King

Realising their folly in openly challenging the Dark Lord after learning of Frodo's capture, the leaders of the Free Peoples treat with the Mouth of Sauron and reluctantly agree to Sauron's terms. Among these terms was the transfer of Isengard to Sauron, who would allow the Mouth to tyrannically rule over the West from Orthanc. However, neither the Dark Lord nor his lieutenant had anticipated that Saruman, the former lord of Orthanc, would not surrender Isengard without a fight.

Task: As Mordor, complete Besiege: Isengard

Allowed Unit Production Structures: Orc Barracks, Troll Cage, Siege Works
