This does not set a mood and thus does not convey the same information. This removes the information about mood and setting away while keeping only rough plot point in.

The outcome in terms of how reader interpret the situation is massively different. The thing you wrote implies that all they need is to go to sleep an hour sooner and rest, all will be fine.

Uh, yes. This is press-release speak, optimised for a fourth grader’s reading comprehension.

If, on the other hand, you want to develop the motif of the Unseen—central to Tolkien’s work—the type of tired the characters are and how they’re detecting and addressing it is incredibly germane, interesting and totally lost in your summary.

You’re also describing the first scenes we see through familiar eyes of Mordor. The landscape is an extension of Sauron’s will. The contrast with the developed, organised, albeit crowded cities of men; the arrogance implied in the desolation; et cetera pack information lost in your summary.
