Going home at night is the main concern for Yeager too. So he runs away from fights, even ones he needs to be in. He left his team to bleed to death so he could go hide in a ditch (google it).
After all the facts were in there was nothing he could have done to help anything, but he didn't know that when he went hiding. I don't know if I would have reacted any differently, but I wouldn't make some of the claims he does if I reacted similar.
