The Return of the King by J.R.R Tolkien (Harper Collins 1991) pp. 793-797
If Denethor had ever made an inaugural address on becoming the Steward of Gondor we could be fairly confident that at its heart would lie the idea, if not the words, Gondor First.
As Denethor and Gandalf debate together about what should have been done with the Ring of Power it becomes clear that Denethor believes that if Gondor were to fall, so too would the West. Indeed, in his mind, the West and Gondor are one thing. Gondor is the last outpost of Númenor, the “West-Land” that lay far to the geographical and spiritual west of Middle-earth, and from which Elendil and his followers first came and founded the kingdoms of Gondor and of Arnor. And so, to Denethor, if Gondor falls “the West is finished”.
To a man with such a vision there is only one thing that can be done with the Ring and that is to keep it and not to use it “unless at the uttermost end of need” when the victory of Mordor over Gondor becomes an inevitability.
Gandalf believes that even with the decision not to use the Ring except in such extreme circumstances the Ring would corrupt and finally overthrow the mind of Denethor, but there is a further point that he makes, one that offers an entirely different vision of reality to the one that Denethor holds.
“You think, as is your wont, my lord, of Gondor only,” said Gandalf. “Yet there are other men and other lives, and time still to be. And for me, I pity even his slaves.”
The word, his, refers of course to Sauron. The slaves of Sauron speak first of all of the people who live by the Sea of Núrnen in the southern and more habitable part of Mordor, and who grow the food that supplies the armies that Sauron stations in the northern parts of that land. Their master is the Gloom of Nurn, one of the Nazgûl who ruled them from his fortress of Thaurband. Tolkien speaks of the sad waters of the lake and so we can understand the life that these people must have led.
The first thing that is clear from what Gandalf says of the slaves of Sauron is that they are not enemies but prisoners to be liberated. And indeed, Aragorn did liberate them after the fall of Sauron and the land about the Sea of Núrnen was given to them as their own possession. But there is a further thing that Gandalf wants to make clear to Denethor, and that is that if his care extends as far as Sauron’s slaves then it extends to all peoples, to Elves and Men, to Dwarves and to Hobbits. For Gandalf there is no hierarchy of peoples and there is certainly no such thing as Gondor First! Yes, Gondor deserves honour because it holds within its memory all that was best about Númenor, the memory that Elendil brought with him to Middle-earth. And it deserves honour because, as Beregond put to Pippin, “we have this honour: ever we bear the brunt of the chief hatred of the Dark Lord, for that hatred comes out of the depths of time and over the deeps of the Sea”. But this honour is shared with all the foes of Sauron and all the peoples of Middle-earth are the creatures of Ilúvatar and are loved by him. As Gandalf says to Denethor, although the Steward of Gondor may believe that he only has one task and that is the welfare of his people, for Gandalf that concept of stewardship is too narrow. Gandalf is a steward of all the peoples of Middle-earth, indeed of all its creatures.
This does not mean that Gandalf has authority over Denethor even as he does not have authority over Aragorn, or Elrond, or Galadriel, or Théoden, or over Frodo for that matter. Gandalf as steward is the servant of all and not the master. His desire is for the welfare of all and so he knows that in many ways he will come into conflict with Denethor, for their interests are not the same.
