On July 29, 1148, Crusader Armies fell back from Damascus instead of taking the city due to differences among the Crusaders. We are going to storm the city instead.

Siege battles are a challenge to wargame. You can never bring the whole situation to the table, considering all the walls, gates, towers, fatigue, starvation, civilians, and so on, into play.

Terrain, build a city with a second set of defenses. The weakest wall, according to historical records, is not a standard straight wall, but instead has several jags and curves to accommodate the landscape. The streets should be narrow, at most 1BW, and also not straight.
Models, build armies as they would have been historically; there should be a 2.5:1 advantage for the crusaders. Also, ladders and rams would be the primary siege equipment due to the short timeline.
