Can you get the army of the dead at helms deep battle for middle earth

The Battle of Middle Earth is a tough concept, you see the varieties of weapons there are pretty much unlimitted and most are useful for anything. One day i was exploring through the forest and something his me on the head. I don't know wat it was. I still dont, but the fact is that middle earth could exist, that story has nothing 2 do with this q but i jst wanted 2 tell some1 lol. Anyway, to do this u will need to head to the torture chambers, east form the entrance and then sneak up behind the Master Ox and kill him, you then need 2 go over to him and pick up the helm. its that simple!! Well actually i spent days and days loking for it because i didnt no there was a torture chamber so yeah!
