I also think "who alone among the Easterlings proved true at need" is a unique piece of information, even if it can be inferred by the action earlier described.

Repetition isn't necessarily a bad thing, quite the contrary, when placed far enough apart, it reinforces what is important, not just to the reader but to the sub-creator.
