It was in trusting to luck on the roads of Mordor that Frodo and Sam were driven northward by the orcs in a forced march almost to the same Black Gate that they had seen from the other side just two weeks before. In those short days they have encountered Faramir and his Rangers of Ithilien; journeyed through the Morgul Vale; made the long climb to the pass of Cirith Ungol and there Frodo has been assailed by Shelob and carried by orcs into Mordor and the tower that guards the pass while Sam has defeated Shelob, briefly taken the Ring and rescued Frodo.
Now as Frodo lies, exhausted by the torment of the march, Sam begins to ponder the journey that still lies before them to Mount Doom.
“‘It looks every step of fifty miles,’ he muttered gloomily, staring at the threatening mountain, ‘and that’ll take a week, if it takes a day, with Mr Frodo as he is.’ He shook his head, and as be worked things out, slowly a new dark thought grew in his mind. Never for long had hope died in his staunch heart, and always until now he had taken some thought for their return. But the bitter truth came home to him at last: at best their provision would take them to their goal; and when the task was done, there they would come to an end, alone, houseless, foodless in the midst of a terrible desert. There could be no return.”
As we shall see as they make this last journey Sam is never quite able to despair. There is always an action that can be taken to get them a little nearer to their goal and, even at the very end, a place that is a little safer than the utter destruction that lies within the Cracks of Doom. Sam cannot quite abandon the optimism that has played such a part in bringing them so far upon the impossible journey. Trusting to luck, to wyrd, on the roads of Mordor that we thought about two weeks ago, was not just the consequence of dire necessity but a part of Sam’s character formed long before. And even when all hope has gone he must give luck every opportunity that he can.
Sam longs for a happy ending to his story and to Frodo’s and it is Rosie Cotton that he first recalls. His longings are for home and family and a woman to share them with and now, for the first time, it seems to him that he is never to enjoy these things. He would have the right to be angry, with Gandalf or Elrond who sent him on such a hopeless task, or with whatever sense of higher power that Sam has but at this moment he discovers something quite new, and even exciting. “He felt through all his limbs a thrill, as if he was turning into some creature of stone or steel that neither despair nor weariness nor endless barren miles could subdue.”
It is only possible to make such discoveries at moments when they become necessary. Life must be entirely wagered on a venture whose outcome is, at best, doubtful, and most likely impossible, before such strength is given. Sam has laid his bets already, choosing to leave the comfortable world from which he came in order to go with Frodo. It is the kind of wager that we all consider at some point of our lives when the really big choices are laid before us. For only the big choices have the kind of degree of uncertainty about them that make us truly afraid. Now Sam sees, for the first time, the possible consequences of his wager and with it his will hardens and mighty strength is given. He is ready to carry himself, and Frodo if necessary, to the mountain and to the end of their journey. And that readiness to see the wager through to the end is what makes Sam great.
