This is an overview map of the main wall against the Ancient's Way. When we get into actual combat, it'll be more focused.

Some Stats:
The Wall is 60ft tall, and 30 ft thick. Built of heavy stone blocks of such quality that you know dwarves must have had a hand in its creation.
Each of the towers is slightly taller (65ft), and boasts a pair of catapults and ballistas with crews to man them. The walls between are manned by archers, skirmishers, and ballista crews, ready to rain death upon the coming horde, and fight off climbers as nessicary.
The gate is heavy oak, bound and studded in iron. 30ft wide, 12ft tall, and over a foot thick. The passage beneath the wall is likewise 30ft wide, and 12ft tall, and 30ft long.
A number of troops man the courtyard, including your own Hammar Company.
Your men are all 3rd lv fighters, clad in dwarven Stone Plate, Large Shields, and weilding Dwarven Urgoshes, with axes and hammars at their belts for closer combat or ranged volleys.
In addition to your fighters, you have 3 mages (2 wizards and a sorcerer), all of whom are lv3. All possess the 'Still Spell' Feat, and are likewise clad in Heavy Stone Plate armor.
Behind the courtyard stands the Inner Curtain Wall. This wall is taller, but not as strong as the outer wall, built for it's commanding view rather than it's strength. Two bridges connect it to the outer wall, to allow for easy reinforcement from one to the other. A number of catapults are placed along it's length, aimed at the area before the gate, but little else possesses the range to be of use.
The Command Tower stands tallest of all surveying all action beneath it. It is here that Captain Bejal sits.
The Inner Gate is larger and flimsier than the outer gate, and stands open incase of need for retreat. It is still well built, and may hold against direct assault for a while.
