When Sam took the Ring and entered Mordor, we get the famous passage that lots of people take for Sam’s test versus the Ring:
Already the Ring tempted him, gnawing at his will and reason. Wild fantasies arose in his mind; and he saw Samwise the Strong, Hero of the Age, striding with a flaming sword across the darkened land, and armies flocking to his call as he marched to the overthrow of Barad-dur. [LR 6.01.018]
I don’t agree that this is the test. This attempt to suborn the faithful Samwise is risible. If that’s the best the Ring can do, it wouldn’t have been a problem for anybody, let alone Boromir, Gandalf, or Galadriel. Tolkien gives us a hint that this idea isn’t quite right, though. The previous sentence takes us into Sam’s thoughts: “He felt that he had from now on only two choices: to forbear the Ring, though it would torment him; or to claim it, and challenge the Power that sat in its dark hold beyond the valley of shadows.” Sam is thinking, which is not his strong point. We shouldn’t expect him to comprehend such an important and subtle matter on the first try.
Tom Hillman points out that the Ring is exploiting the way Sam loves old fairy-stories. Sam is a romantic. In that passage, the Ring is using Sam’s romanticism against him. That’s what the Ring does, as we know. It attacks your virtues. It uses your strengths against you. But a fondness for old stories and songs is more of an endearing trait than a great virtue. It’s not where the Ring would try Sam, when we know that he has a great virtue to work with. That’s where we should expect the Ring to attack first.
Sam’s great virtue is his loyalty to Frodo. That’s where the Ring ought to start to work on him, and sure enough, it did. Back in “The Choices of Master Samwise” we saw the real attack.
He flung the Quest and all his decisions away, and fear and doubt with them. He knew now where his place was and had been: at his master’s side, though what he could do there was not clear. [LR 4.10.057]
Right there, Sam lost the contest of wills with Sauron’s Ring. Fortunately, being Sam, he botches the attempt to rescue Frodo, loses the orcs in the tunnel, and concusses himself on the door. The Ring fails to get back to Sauron, and Middle-earth survives for another day.
People who like to find the hand of the Valar in any lucky break will be disappointed, but Sam’s failure to make a heroic stand over Frodo’s body isn’t a eucatastrophe. It was predictable. Indeed, it was predicted back at the beginning of the story! I knew not that Pippin, of all people, was a hobbit foresighted, but he’s the one who said, “Sam is an excellent fellow, and would jump down a dragon’s throat to save you, if he did not trip over his own feet,” and he was almost exactly right. [LR 1.05.060]
It’s only fair. If Sauron can turn people’s strengths into vulnerabilities, some Vala or other ought to be able to turn klutziness into a world-saving virtue. There may be hope for me yet.
