"I'll hold you in reserve until I get further orders from headquarters, I think. General Harkness evidently plans an aggressive fight from the very outset. I have heard nothing from his headquarters direct as yet, but I probably shall pretty soon. I shall send in a report of General Bean's success at Hardport at once, though he has probably done that already."
The Scouts were working well all along the line. The enemy, as Pete Stubbs had reported, had crossed the State line in some small force at Mardean. Two regiments had occupied that village, which was on the Red side of the line, and had thrown out skirmishers for a couple of miles in both directions. Warner, one of the Raccoon Patrol, had been captured, but he was the only one of the Troop who had not made good his escape in the face of the enemy's advance, and even he had accomplished the purpose for which he had been sent out, since he had managed to wig-wag the news of the advance of a troop of cavalry before they had run him down, and the news had been flashed all along the line, from Scout to Scout, until it had reached Durland.
The wireless was not in use here, though experiments were being made with a field wireless installation some miles away, but the Scouts did not need it. They were spread out within plain sight of one another, and with their little red and white flags they sent messages by the Morse alphabet, and in a special code, as fast as wireless could have done. They also were prepared to use, when there was a bright sun, which was not the case that day, the heliograph system, which sends messages for great distances.
In that system of field signalling, extensively employed by the British during the Boer war, since wireless had not at that time been at all perfected, a man stands on a slight elevation, and catches the rays of the sun on a great reflector. Those flashes are visible for many miles in a clear atmosphere, in a flat country, and the flashes, of course, are practically instantaneous.
"We don't need to worry about wireless for communications of a few miles," said Durland. "The system of signalling that depends on seeing flashes, smokes, flags and other signals, is as old as warfare, really. The Indians, in this country, used to send news an astonishing distance in an amazingly short time. They used smokes, as we know, since we have all worked out those signals ourselves from time to time. And all nations in time of war have employed relays of men with flags, stationed at fixed intervals for scores of miles, for the sending of despatches and important news. Napoleon used the system on a great scale, and, until the telegraph was invented and made practicable for field work, that was the only way it could be done."
"The telegraph was first used in our Civil War, wasn't it, sir?" asked Tom Binns.
"Yes. But even then it was done in a very crude way. There was none of the modern elaborate work of field telegraph systems. Nowadays, you see, an army builds its telegraph lines as it goes along. Then they were dependent upon the lines already built, mostly along the railroad tracks. The first really great war in which such systems were in use was the struggle between Russia and Japan. The French and the Germans didn't have them in their war."
A few minutes later an orderly from the building in which the field telegraph station had been established came running up to Durland.
"Despatch from General Harkness, Captain," he said, saluting, and Durland took the slip of paper. He flushed with pleasure as he read it.
"Concentrate your troop at Hardport," he read. "Send Danby and companion in scout car ahead, to report to me for special duty. Congratulations on his splendid work, reported to me fully by General Bean."
