The Fellowship of the Ring
Suddenly Boromir came and sat beside him. "Are you sure that you do not suffer needlessly?" he said. "I wish to help you. You need counsel in your hard choice. Will you not take mine?"
"I think I know already what counsel you would give, Boromir," said Frodo. "And it would seem like wisdom but for the warning of my heart." (2.10.24-5)
"We of Minas Tirith have been staunch through long years of trial. We do not desire the power of Wizard-lords, only strength to defend ourselves, strength in a just cause. And behold! in our need chance brings to light the Ring of Power. It is a gift, I say; a gift to the foes of Mordor. It is mad not to use it, to use the power of the Enemy against him. The fearless, the ruthless, these alone will achieve victory. What could not Aragorn do? Or if he refuses, why not Boromir? The Ring would give me power of Command. How I would drive the hosts of Mordor, and all men would flock to my banner!" (2.10.36)
Horsemen were galloping on the grass of Rohan; wolves poured from Isengard. From the havens of Harad ships of war put out to sea; and out of the East Men were moving endlessly: swordsmen, spearmen, bowmen upon horses, chariots of chieftains and laden wains. All the power of the Dark Lord was in motion. Then turning south again he beheld Minas Tirith. Far away it seemed, and beautiful: white-walled, many towered, proud and fair upon its mountain-seat; its battlements glittered with steel, and its turrets were bright with many banners. Hope leaped in [Frodo's] heart. But against Minas Tirith was set another fortress, greater and more strong. Thither, eastward, unwilling his eye was drawn. It passed the ruined bridges of Osgiliath, the grinning gates of Minas Morgul, and the haunted Mountains, and it looked upon Gorgoroth, the valley of terror in the Land of Mordor. (2.10.54)
