The paragraph that best develops Henry's character is when the narrator locate them on the way to Washington, describing him as:
He had grown to regard himself merely as a part of a vast blue
demonstration. His province was to look out, as far as he could, for his
personal comfort. For recreation he could twiddle his thumbs and
speculate on the thoughts which must agitate the minds of the generals.
Also, he was drilled and drilled and reviewed, and drilled and drilled and
reviewed.
