And the men of Israel were defeated there by the servants of David, and the loss there was great on that day, twenty thousand men. The battle spread over the face of all the country, and the forest devoured more people that day than the sword.
2 Samuel 18:7-8
The hosts of Isengard roared, swaying this way and that, turning from fear to fear. Again the horn sounded from the tower. Down through the breach of the Dike charged the king’s company. Down from the hills leaped Erkenbrand, lord of Westfold. Down leaped Shadowfax, like a deer that runs surefooted in the mountains. The White Rider was upon them, and the terror of his coming filled the enemy with madness. The wild men fell on their faces before him. The Orcs reeled and screamed and cast aside both sword and spear. Like a black smoke driven by a mounting wind they fled. Wailing they passed under the waiting shadow of the trees; and from that shadow none ever came again.
