Against the Deeping Wall the hosts of Isengard roared like a sea. Orcs and hillmen swarmed at its feet from end to end. Ropes with grappling hooks were hurled over the parapet faster than men could cut them or fling them back. Hundreds of long ladders were lifted up. Many were cast down in ruin, but many more replaced them, and orcs sprang up them like apes in the dark forests of the South. Before the wall’s foot the dead and broken were piled like shingle in a storm; ever higher rose the hideous mounds, and still the enemy came on.
