The End of Their Folly

"Upon the battlement nothing could be seen. All was silent but watchful. They were come to the last end of their folly, and stood forlorn and chill in the grey light of early day before towers and walls which their army could not assault with hope, not even if it had brought thither engines of great power, and the Enemy had no more force than would suffice for the manning of the gate and walls alone."
~ from The Return of the King, by J.R.R. Tolkien
