#FellowshipOfTolkien
The way Tolkien describes Sam and Frodo's bond in this last leg of the journey, the most harrowing, makes me think he must have had a real-life example in mind. It's so realistic and involving that he can't have made it up.
I wonder if he saw this kind of comradery in the trenches of WWI. Soldiers developed a very peculiar, uncommon bond in those terrible circumstances. May Tolkien have had that in mind when he wrote this?
