** TTT - Helm's Deep 2

The assailing hosts halted, foiled by the silent menace of rock and wall. Ever and again the lighting tore across the darkness. Then the Orcs screamed, waving spear and sword, and shooting a cloud of arrows at any that stood revealed upon the battlements; and the men of the Mark amazed looked out, as it seemed to them, upon a great field of dark corn, tossed by a tempest of war, and every ear glittered with barbed light.
