What are some character traits of Peyton Farquhar in An Occurence at Owl Creek Bridge?

Peyton Farquhar is the protagonist in Ambrose Bierce's short story entitled "An Occurrence at Owl Creek Bridge." He is described as a wealthy plantation owner from a highly respected Alabama family. He was a secessionist, meaning that he supported the Southern cause of leaving the union. The story is set during the American Civil War, when the issue of slavery divided the country. Bierce describes Farquhar as "ardently devoted to the Southern cause."
Peyton Farquhar was a husband and a father. Readers can infer that he was devoted to his wife and children. Right before his death by hanging, his family occupies his thoughts. The narrator mentions later in the story that it is the thought of his wife and children that spurs Farquhar on.
Bierce describes him as one who longed to be a soldier fighting on the front lines, which he imagined released pent-up energy and carried honor and glory with it. But his services were apparently needed as a spy, so he was unable to fulfill this desire. Because of their work, spies must be able to lie, to deceive, and to gain the trust of the enemy. Readers can infer that these were characteristics Farquhar possessed.

"Circumstances of an imperious nature, which it is unnecessary to relate here, had prevented him from taking service with that gallant army which had fought the disastrous campaigns ending with the fall of Corinth, and he chafed under the inglorious restraint, longing for the release of his energies, the larger life of the soldier, the opportunity for distinction. That opportunity, he felt, would come, as it comes to all in wartime. Meanwhile he did what he could. No service was too humble for him to perform in the aid of the South, no adventure to perilous for him to undertake if consistent with the character of a civilian who was at heart a soldier, and who in good faith and without too much qualification assented to at least a part of the frankly villainous dictum that all is fair in love and war."

It's interesting to note that he considers himself a "student of hanging." That could be due to his work as a spy, but one wonders if it also has something to do with his life as a plantation owner.
