Helm's Deep Query

[Knight of Gondor]

The tactic was the same in the books. The uruks arrived and began pouring arrows onto and into the Helm's Deep, "but from behind the walls came no reply." I am guessing the reason was two-fold.

First, that despite the fact that thousands of heavily-armed uruk-hai were marching on their fortress, having burned and pillaged as they came, there was a policy of not initiating the attack.

Second, the more practical reasons of not wasting arrows, and waiting for good light and distance to make better use of them.

For firing without orders from his king or general(s).

The technology wasn't so easy in Middle-Earth as it is here. They had, what? two? three? bombs at best. The bombs were filled with the concoction, which must have taken Saruman a long time to brew, so those bombs in and of themselves were quite an accomplishment.
