For the next two days nothing was seen of Early, although the cavalry and both of the infantry corps of the main line kept a good watch toward the front. There was some probability that Early would attack, especially if he should have heard of Wright's departure and not of his return. That Early must either attack soon or withdraw to the head of the valley was certain, for Sheridan had stripped the country of the supplies on which the Confederates had been accustomed to rely, and Early had now to feed his men and animals by the long haul of seventy-five miles from Staunton. It was thus that Wright viewed the situation, and in fact the same things were passing through the mind of Early. On the 18th of October, Crook, by Wright's orders, sent Harris with his brigade of Thoburn's division, to find out where Early really was and what he was doing. How far Harris went is not certainly known, but when he returned at nightfall he reported that he had been to Early's old camps and found them evacuated. In reality Early was at Fisher's Hill with his whole force, engaged in his last preparations for the surprise of the morrow, but the report brought back by Harris soon spread as a camp rumor among the officers and men of Crook, so that they may have slept that night without thought of danger near, and even the vigilance of their picket line, as well as that of the cavalry to whom they largely looked for protection against a surprise, may or may not have been inopportunely relaxed. For Early, warned of the strength of Sheridan's right, by the failure of Rosser's adventure, had since been studying the chances of an attack on the opposite flank. To this indeed the very difficulty of the approach invited, for in all wars enterprises apparently impracticable have been carelessly guarded against and positions apparently impregnable have been loosely watched and lightly defended, so that it might not be too much to say that every insurmountable difficulty has been surmounted and every impregnable stronghold taken. Such apprehensions as the commander of the Union army may be supposed to have entertained were directed toward his right, where Torbert was, and where the back road to Winchester gave easy access to his rear.
