It did not occur to Kilgariff to invite Doctor Brent to take refuge in one of the bomb-proofs till the fierceness of the fire should be past. It never did occur to Owen Kilgariff that a gentleman of education and culture could think of shrinking from danger, even though, as in this case, he had nothing to do with the war business immediately in hand, but was, technically at least, a non-combatant. Indeed, that gallant corps of doctors who constituted the medical field-service in the Confederate army never did regard themselves as non-combatants, at least so far as going into or keeping out of danger was concerned. They fired no guns, indeed, but in all other ways they participated in the field-fighting on quite equal terms with officers of the line. Wherever their duty called them, wherever an errand of mercy demanded their presence, they went without hesitation and stayed without flinching. They performed the most delicate operations, where a moment’s unsteadiness of hand must have cost a human life, while shells were bursting about their heads and multitudinous bullets were whistling in their ears. Sometimes their patients were blown out of their hands by a cannon shot. Sometimes the doctors themselves went to their death while performing operations on the battlefield. In one case a surgeon was shot unto death while holding an artery end. But while waiting for the death that he knew must come within the brief space of a few minutes, the gallant fellow held his forceps firmly and directed his assistant how to tie the blood vessel. Then he gave up the ghost, in the very act of thus saving a human life perhaps not worth a hundredth part of his own. The heroism of war does not lie altogether with those who make desperate charges or desperately receive them. Arthur Brent was high in rank in that medical corps, the cool courage of whose members, if it could be adequately set forth, would constitute as heroic a story as any that has ever been related in illustration of daring and self-sacrifice, and he honoured his rank in his conduct. His duty lay sometimes in the field, whither he went to organise and direct the work of others, and sometimes in the laboratory, where no element of danger existed. In either case he did his duty with never a thought of self and never a question of the cost. On this occasion he stood upon the exposed mound of the magazine, watching Kilgariff’s splendid work with the guns, until at last the bombardment ceased as suddenly and as meaninglessly as it had begun; for that was the way with bombardments on those lines. When at last the fire sank to its ordinary dead level of ceaseless sharp-shooting, with only now and then a cannon shot to punctuate the irregular rattle of the rifles, Kilgariff gave the order, “Cease firing,” and the clamorous mortars were stilled. Then he turned to the officers who had come to him for instruction, and said:—
