Whenever a severe mortar fire was opened upon his line of pits, he would station himself in a peculiarly exposed position on top of the earth mound that protected his magazine. From that point he could direct the work of every gun under his command and at the same time do much for the protection of his men. A mortar shell can be seen in the air—particularly at night, when its flaming fuse is a torch—and its point of contact and explosion can be calculated with a good deal of precision. It was Kilgariff’s practice to watch for the enemy’s shells, and whenever he saw that one of them was likely to fall within one or other of his pits and explode there with the certainty of blowing a whole gun detachment to atoms, he would call out the numbers of the exposed pits, whereupon the men within them would run into the boom-proofs provided for that purpose and shelter there till the explosion was over. In the meanwhile, he, posted high upon the magazine mound, was exposed not only to the mortar fire that endangered his men, but still more to a hail-storm of musket bullets and to a ceaseless flow of rifled cannon shells that skimmed the edge of his parapet, with fuses so skilfully timed and so accurately cut that every shell exploded within a few feet of his head. Perhaps he was thinking of the kindly bullet or the friendly shell fragment that was to make an end of his perplexities. Who knows? Yet his exposure of himself was not reckless, but carefully calculated for the preservation of his men. It was only such as was common among the Confederate officers at Petersburg, where the percentage of officers to men among the killed and wounded was greater than was ever recorded in any war before or since. By this exposure of his own person Kilgariff undoubtedly saved the lives of many of his men, all of whom were volunteers who had offered themselves to man a position so dangerous that the chief of artillery had refused to order mortars to occupy it, and had reluctantly consented to its occupation by Kilgariff and his desperately daring men as volunteers in an excessively perilous service. He might have reduced his losses still more if he had been willing to order his subordinates at the several groups of pits to expose themselves as he did in the interest of the men. But this he refused to do, on the ground that to order it would be to exact more than even a soldier’s duty requires of the bravest man. One of his sergeants—a boy of fifteen, who had won promotion by gallantry—had indeed emulated his captain’s example in the hope of sparing his men. But the second time he did it, a Hotchkiss shell carried away his head and shoulders, and the world suffered loss.
