six o'clock in the morning
The orders given the engineer were to move back at a snail 's pace until he reached Concho again . There he was to remain for two hours . That Chaves would submit to this O'Halloran did not for a moment suspect . But the track would be kept obstructed till six o'clock in the morning , and a sufficient guard would wait in the underbrush to see that the right of way was not cleared . In the meantime the wagons would be pushing toward Chihuahua as fast as they could be hurried , and the rest of the riders would guard them till they separated on the outskirts of the town and slipped quietly in . In order to forestall any telegraphic communication between Lieutenant Chaves and his superiors in the city , the wires had been cut . On the face of it , the guns seemed to be safe .
