[LOtR] Why didn't Sauramon keep any Uruk-hai to defend Isenguard during the battle for Helm's Deep?

He actually kept a small garrison of Orcs to keep making Uruk-hai and prevent squatters/bandits. In his arrogance though, he never expected the Ents to attack and never imagined Rohan would survive his army's onslaught at Helms Deep. So he simply sent them all to fight Theoden.
