[Numenorean]

During my current re-reading of LoTR I've discovered that what I love about Boromir is his tremendous valour in the face of an overwhelming enemy. Sure theres the part that everyone refers to, killing the 40 or so Uruks and trying to save Merry & Pippin, but I've come to believe that Boromirs bravery is best described in Moria at Khazad Dûm. There his actions were not just brave, they were legendary, and even on a par with Aragorn himself.

As the Fellowship realise that hundreds of Orcs and worse still, a Balrog, are closing in on their position, Legolas drops his arrow in fear and wails, "Ai, ai! A Balrog! A Balrog is come!" Gimli gives it a "Durins Bane!" then lowers his axe and covers his face. Gandalf says it is "an evil fortune" and the rest (including Aragorn) do nothing. Boromir though, in blatent defiance of this terribly powerful foe, "raised his horn and blew. Loud the challange rang and bellowed...For a moment the orcs quailed and the fiery shadow halted."

Next we have Gandalf telling the Fellowship to 'Fly!' across the bridge, yet "Aragorn and Boromir did not heed the command, but still held their ground, side by side, behind Gandalf at the far end of the bridge."
Once the Balrogs first blow is deflected it "leaped full upon the bridge" towards a "grey and bent" Gandalf, then: "He cannot stand alone!' cried Aragorn suddenly and ran back along the bridge. 'Elendil!' he shouted.'I am with you Gandalf!' 'Gondor!' cried Boromir and leaped after him."

Boromirs courage under fire, his standing shoulder to shoulder with Aragron in defence of Gandalf and the Fellowship, and his total readiness to face almost certain defeat by the Balrog, all display his excellent bravery and honour. At Parth Galen Boromir had to try and make amends for his attempt to take the Ring, but in Moria he was acting out of pure comradeship and his own great valour.
