You're right not to mention the name Jack, there no need to blame the poor man. He might not have been a warrior he was nontheless fighting for his country and telling his name will not bring anything more to your story. You are a fair and generous person.
How were things with sleeping? You mentionned that you slept whereever you had a chance, but did you have enough sleep at all or were you constantly woken up by battle , bugs and other nuisances that would hinder you from recovering? Or did you actually have a chance to get a rest between two fights?
