From what you already know about Detering, why is his behavior in this chapter understandable, or "in character"?

Detering's burning desire to leave for home is an expression of what all the men repress, the need to escape from their "artificial" stoicism. However, there is a reason he is the only one who leaves; he is one of the few young men with a real home and profession. If the others had more compelling reasons to return home, they would probably have deserted long ago.
