聖盔谷
The garrison of Helm's Deep consisted of some 1,000 men, but around 1,000 more defenders had arrived from across Rohan by the time of the battle. The enemy, Saruman's army, consisted of at least 10,000 Orcs and men, most marching from Isengard to Helm's Deep, and others heading to the Fords of Isen. An additional force of Men of Dunland joined the enemy.
