So I'm watching the two towers and I cant help but try to understand why it was so important to win helms deep. Rohan was down to a few hundred men, they were hiding in a mountain.
It would have been wiser to send a few thousand orcs to sit outside Helms deep to barricade them in and siege them to side-line Rohan. And use the bulk of Isengaard's army to a coordinated attack with mordor's forces to gondor.
Or if not gondor, focus on the elves, who just lost a bunch of people to ferry across the sea.
Or if not the elves or gondor, continue to hatch orcs and arukia (whatever) until you can replace the numbers sieging helms deep.
There is very little tactical advantage to throwing "tens of thousands" at a stronghold to kill a few hundred fighting men. You have already taken their lands and cities. The kingdom had fallen.
