Beyond a mere “Thank you, Captain,” Kilgariff made no response. Half an hour later his section was detached and sent to a point of special difficulty and danger. He plunged into action with an impetuosity which surprised General Ewell, who was in personal command at that point, and whose uniform habit it was to place himself at the post of danger. But a moment later, observing the discretion with which Kilgariff selected a position of vantage and planted his guns, with equal reference to their effectiveness and their safety from capture by a dash of the enemy, General Ewell turned to his staff, and said:— “That young man evidently knows his business. Who is he?” Nobody knew. “Then find out,” said Ewell. Meanwhile, Kilgariff was using canister in double charges, the range being not greater than two hundred yards. Under this withering fire the enemy gave way at that point, and Ewell’s whole line advanced quickly. Again Kilgariff selected his gun position with discretion, and opened a murderous fire upon the enemy’s key position. But this time he did not use canister. Still, his fire seemed to have all the effect of canister, and his target was for a brief while less than fifty yards distant from the muzzles of his guns. Presently Ewell himself rode up to the guns, and asked, in his peculiarly querulous voice:— “What ammunition are you using, Sergeant-major?” “Shrapnel, doubled and fuse downward,” answered Kilgariff. “It’s hard on the guns, I know, but I’ve run out of canister, and must use what I can, till a new supply comes. I’ve sent for it.” It should be explained that shrapnel consists of a thin, hollow shell of iron, filled with leaden bullets. In the centre of each shell is a small charge of powder, intended only to open the shell twenty-five yards or so in front of an enemy’s line, and let the leaden bullets with their initial impetus hurl themselves like hailstones into the faces of the troops. But Kilgariff was turning his shrapnel shells reverse way, with their fuses toward the powder charge, so that the fuses should be melted at the moment of firing, and the shells explode within the gun, thus making them serve the purpose of canister, which consists of tin cans filled with iron balls. “Where did you learn that trick?” queried Ewell. “Oh, I suppose every artillery-man knows it,” answered the sergeant-major, evasively. “But here comes a fresh supply of canister, so I may spare the guns.”
