The Two Towers
As Aragorn searches for Frodo, he suddenly hears Boromir's horn. Aragorn finds Boromir mortally wounded by arrows, sitting with his back against a great tree, surrounded by many slain orcs. Before Boromir dies, Aragorn learns that Saruman's Uruk-hai soldiers have kidnapped some of the hobbits, in spite of his efforts to defend them; that Frodo had vanished after Boromir had attempted to take the Ring from him; and that he truly regretted his actions.
