"Whatever happens, sir, mind you keep close to the captain," was his parting injunction to his boy. Then his heels came together with the old cavalry "click" and his twitching fingers were stiffened as they went suddenly up in salute to Mr. Rayburn, who bent down from his saddle to say that they would try and take good care of Fred. But Waller answered:
"I thank the lieutenant. The boy is a soldier now, sir. He must take his chances with the rest." Then with one lingering clasp of the trumpeter's hand, "Join your captain," he ordered, and turned away into the darkness.
But the sentry on No. 6 bore witness to the fact that the ordnance sergeant never went to bed again all that night, and the men sent to unload and store the ammunition that came next day from Rock Island Arsenal declared that old Waller was gruffer than ever. All the next night too, he was awake, waiting, watching for tidings from the North. Nothing came until sunset of the second day, just as the whole command was turning out for retreat parade, and then Corporal Rock rode in with dispatches and trotted straight to where the commanding officer was standing in front of the adjutant's office. All eyes were upon him as he threw himself from the saddle and handed the packet to the colonel. Half a dozen officers hastened to join their commander as he tore it open. The piazzas of the officers' quarters were quickly alive with ladies and children, breathlessly eager to hear the news. The colonel's orderly was seen hastening to the surgeon's house--that looked ominous--then Rock remounted; trotted to Captain Charlton's gate, where Mrs. Charlton was tremblingly awaiting him. "It's all right, ma'am," he hastened to say. "Leastwise the captain's safe, but Mulligan is shot--and Ryan and Sergeant Frazer." She hurried in the house with the precious letter he placed in her hands, and while several ladies hastened to join her, the messenger returned to the office.
All this while Sergeant Waller had stood like a statue under the tall white flag-staff where the non-commissioned staff assembled at retreat, watching every move with dry, aching eyes, and a face gray as his mustache.
The trumpet played the retreat, the sunset gun thundered its good-night to the god of day; the adjutant hurried over and received the reports of the companies, the staff, and band, and then a messenger came running to them: "Mrs. Charlton wants you, Sergeant Waller. Fred's all safe, but they had a sharp fight."
