The hobbits continue their journey to Rivendell with Aragorn. On the mountain Weathertop they are attacked by the Ringwraiths, and Frodo is badly wounded by their leader, the Witch-king. Aragorn can defend them, and helps Frodo to stay alive. Along the way they meet the elf Glorfindel. Shortly before Rivendell they are attacked again. Frodo can flee on Glorfindel's horse, followed by the Ringwraiths. Frodo crosses the river Bruinen, beyond which is Rivendell, but the Ringwraiths still follow him. Suddenly the river floods, which carries the Ringwraiths away. Frodo falls unconscious because of the stab wound.
