Besides the battle between the uruk-hai and the rohirrim have their been any other battles between the rohirrim and others at Helms Deep? Such as the dunlendings, orcs etc?

The Rohirrim were defeated and their land was overrun; and those who were not slain or enslaved fled to the dales of the mountains. Helm was driven back with great loss from the Crossings of Isen and took refuge in the Hornsburg and the revine behind (which was later known as Helm's Deep). Their he was besieged. Wulf took Edoras and sat in Meduseld and called himself king.
He [Helm] would go out by himself, clad in white, and stalk like a snow-troll into the camps of his enemies, and slay many men with his hands. It was believed that if he bore no weapon no weapon would bite on him. The Dunlendings [enemy] said that if he could find no food he ate men.
