Courage was not always a matter of yes or no. Sometimes it came in degrees, like the cold; sometimes you were very brave up to a point and then beyond that point you were not so brave. In certain situations you could do incredible things, you could advance toward enemy fire, but in other situations, which were not nearly so bad, you had trouble keeping your eyes open. Sometimes, like that night in the shit field, the difference between courage and cowardice was something small and stupid.
