(That is in fact why castles went out of fashion. Cannons and other gunpowder weapons made the walls useless.)

So, Golmag had ordered that rather than stones, the catapults be loaded with Orc bombs instead. After that, it was an easy task of firing from beyond bow shot and closer than the closest range of the trebuchets. While it took a bit of work to figure out what this 'goldilocks zone' was, the engineers did find it. Now, the catapults bombarded the walls. Eventually, the bombs made a large breach.

No! You underestimate Taured-Doriath! Half of the orc army would be dead by know! Those walls were made consistantly strong back in the first age. Also, Taured-Doriath not only has compressed air bows, the have mithril alloy catapults. He would have to retreat and wait for his enemy to come to him.
