Chapter 10

The tattered man is still thinking about how amazing it was that Jim had that much strength before he died to run from him and Henry. finally they leave Jim lay there and the tattered man talks about how is doesn't feel good at all and then when he says that Henry worries that that tattered man will die on him to and he doesn't want to see another death right now, but the tattered man says that he won't die because he has family with children and he has to make it home to them. he starts talking more and more and tells how he saw some soldier get shot in the head and he didn't even realize he was even hurt until he was dead. then the tattered man thinks Henry is his old friend Tom Jamison and tells him that he also looks weak, and that he should get his injury looked at by someone or it could get infected or worse.
Question: how does the tattered man get Henry and this Tom Jamison guy confused? Who is he, or does it not matter?
