Early's skirmish line was instructed early in the night to "feel" the Federal pickets, an instruction which resulted in a perfect blaze of carbine fire from Wisewell's men. The report that went to Early was that the picket line must be about six thousand strong. The conclusion on the part of the old Confederate commander was that the troops from the army of the Potomac must have reached the city. If that were true, there was, of course, no chance that on the following day he could break through the entrenchments, while there was considerable risk that his retreat to the Shenandoah might be cut off. Early the next morning, therefore, the disappointed Early led his men back to Falling Waters. I happened during the following winter, when in prison in Danville, to meet a Confederate lieutenant who had been on Early's staff and who had lost an arm in this little campaign. He reported that when Early, on recrossing the Potomac, learned that he had had Washington in his grasp and that the divisions marching to its relief did not arrive and could not have arrived for another twenty-four hours, he was about the maddest Early that the lieutenant had ever seen. "And," added the lieutenant, "when Early was angry, the atmosphere became blue." VIII THE FINAL CAMPAIGN After this close escape, it was clear to Grant as it had been clear to Lincoln that whatever forces were concentrated before Petersburg, the line of advance for Confederate invaders through the Shenandoah must be blocked. General Sheridan was placed in charge of the army of the Shenandoah and the 19th corps, instead of returning to the trenches of the James, marched on from Washington to Martinsburg and Winchester.
