Tolkien's Battle of Five Armies is described from Bilbo's POV as the experience "he was most proud of, and most fond of recalling long afterwards, although he was quite unimportant in it." He was invisible. He was watching with misery. His last act was to spot the Eagles — then a stone felled him. He was "quite unimportant" to the battle's outcome. But the outcome depended on what he'd done the night before: slipping alone through the camp in the dark and handing over the Arkenstone. Tolkien keeps doing this. The decisive action is interior, invisible, nocturnal. The dramatic spectacle is downstream of it. The courage that matters most is the kind no one sees — including, sometimes, the person who did it.
