What are some of the "youthful lieutenant"'s idiosyncrasies and character qualities? Are any of the leaders fearless or inspiring?

He is described as a brute:

"He was surprised presently by the young lieu-tenant of his company, who began heartily to beat him with a sword, calling out in a loud and insolent voice: “Come, young man, get up into ranks there. No skulking’ll do here.” He mend-ed his pace with suitable haste. And he hated the lieutenant, who had no appreciation of fine minds. He was a mere brute."

The leaders are not very insipiring.
