Let's Change Forts

Sieges can last more than a year. At that point, defenders of the fort are usually down to eating bugs, shoe leather, and each other.

All Saruman had to do was lock them up in there for a few weeks and Rohan would have died. Then wait for Gandalf on the fifth day, and kill his ***.

There has been real-world sieges, of cities, that have lasted for years -- and Saruman was on a deadline. Dawdling would not be appreciated by his betters ... worsers?

Besides, even if Saruman hadn't attacked Helm's Deep head on, he would still have lost the moment the Ents showed up on the field.
