When I have a noun phrase that contains a pronoun as a subject (of the phrase), but the noun phrase is being used as the direct object of another verb, is the pronoun in the nominative case or the objective case?
For example, sans noun phrase:
Please tell him.
With noun phrase:
Please tell [he/him] who walks through the door.
Or, when being used more as a subordinate clause (?):
Please tell [whoever/whomever] walks through the door.
Or in a concrete example from literature, I was always under the impression that because the pronoun is the subject of a phrase, it's in the nominative case:
If ye break faith with we who die
But the actual poem I'm quoting here says:
If ye break faith with us who die
(The poem being In Flanders Fields by John McCrae) Is this just a poetic device, or is McCrae correct?
What is the generally accepted rule among "correct" English, and why?
