During the ten days' march to Baker City, officers and men became thoroughly acquainted with one another, and the many obstacles they had had to overcome in common cemented the regiments into real living organisms. And when, on the tenth of August, the different columns reached Baker City, the Northern Army had firmly established its marching ability. The transport-service, too, had got over its first difficulties. From the front, where small detachments were continually skirmishing with the enemy, came the news that the Japanese had retreated from Baker City after pulling up the rails. On the evening of the eleventh of August the 28th Militia Regiment was bivouacking a few miles east of Baker City. The outposts towards the enemy on the other side of the town were composed of a battalion of Regulars. Every stone still burned with the glowing heat of the day, which spread over the warm ground in trembling waves. The dust raised by the marching columns filled the air like brown smoke. The last glimmer of the August day died down on the western horizon in a crimson glow, and a pale gleam of light surrounded the dark silhouettes of the mountains, throwing bluish gray shadows on their sides. Then all the colors died out and only the stars twinkled in the dark blue heavens. Far away in the mountains the white flashes of signal-lanterns could occasionally be seen, telling of the nearness of the enemy. Colonel Katterfeld had ordered the officers of his regiment to come to his quarters in a farm-house lying near the road, and a captain of Regulars was asked to report on the number of skirmishes which had taken place in the last few days and on the enemy's position. It was learned that Marshal Nogi had retreated from Baker City and had withdrawn his troops to the Blue Mountains, taking up his central position at the point of the pass crossed by the railroad. It had not been possible to ascertain how far the wings of the Japanese army extended to the North or South. It was certain that the enemy maintained strong lines of communication in both directions, but it was difficult to determine just how far their lines penetrated into the wooded slopes and valleys. * * * * * When the guard was relieved at 5 o'clock in the morning, one of the non-commissioned officers was struck by a curiously-shaped bright cloud the size of a hand, which hung like a ball over the mountains in the west in the early morning light. "It must be an air-ship!" said some one. "It evidently is; it's moving!" said the sergeant, and he at once gave orders to awaken Captain Lange. The captain, who had gone to sleep with the telephone beside him, jumped up and could not at first make out where the voice came from: "A Japanese air-ship has been sighted over the mountains." He was up in a second and looking through his glasses! Sure enough! It was an air-ship!
