I was wondering about the following sentence (from the book "Before They Are Hanged" by Joe Abercrombie):
"He is not fit for battle that has never seen his own blood flow, who has not heard his teeth crunch under the blow of an opponent, or felt the full weight of his adversary upon him."
Since I'm not a native speaker I got confused by the first "that" in the sentences - is it referring to "he"? Is that an old way of saying things in English? Up to now I have not seen anybody using "that" instead of "who" but that is (for me) the only way the sentence would make sense.
Thank you for any input on this case!
