Archer turned half-angrily upon the speaker. "You never yet, Captain Bonner, have heard of Apaches attacking a garrisoned post, even though the garrison was smaller than ours, and I believe you never will. The question _I_ have to settle is how to send warning to our two field columns." For a moment there was none to offer suggestion. There were present only seven officers, all told, Bentley being still with his young patient. Anxious eyes were watching the little group, their white coats gleaming in the moonlight. Over at the barracks a score of soldiers, slipping from their bunks, clustered at the wide-open doors and windows. Over at the hospital two or three convalescents, with the steward and the nurse, sat gazing from the shaded piazza. Over at the commander's quarters Mrs. Archer, Mrs. Stannard and Lilian, sitting closer for comfort, murmured occasional words, but their eyes seldom quit their anxious scrutiny. To Mrs. Stannard it was no novel experience. To Mrs. Archer and her daughter, despite their longer years in the army, it was thrillingly new. In the utter silence on the line and throughout the garrison the rhythmic tramp of feet, muffled by distance, could not fail to catch their straining ears, and far over across the parade, behind the barracks, betrayed by the glint of the moonlight on sloping steel, a shadowy little detachment went striding away toward the nearest sentry post. "They are doubling the guard," said Mrs. Stannard. Then the group at the flagstaff broke up. Three officers went with the commander toward the office, others toward the company quarters. One came swiftly, purposely, toward the waiting trio. Lilian knew it was Willett even before they could recognize his walk and carriage. Mrs. Archer rose to meet him. All they yet knew was that 'Tonio was in with tidings of some kind--Doyle had told them that. "Tell us what you can," was all she said. "The time-honored tale of Indian uprising," said Willett airily. "Something I've heard every six weeks, I should say, since they gave me a sword." "But they've doubled the guard." "Only changed it, I fancy. The general wants some few cavalrymen for a scout in the Mazatzal." Mrs. Stannard knew better, but held her peace. The object at least was laudable, if not the lie. All three had risen now and were standing at the edge of the veranda, Mrs. Archer's gentle, anxious eyes following the soldierly form just vanishing within the shadows at the office, Lilian's gaze fixed upon the handsome features of the young soldier before her. "'Tonio brought news, did he not?" asked Mrs. Stannard.
