On September 29, Mosby was back with his command; his wound had not been as serious as it might have been for the bullet had expended most of its force against the butt of one of the revolvers in his belt. Operations against the railroads had been allowed to slacken during Mosby's absence; now they were stepped up again. Track was repeatedly torn up along the Manassas Gap line, and there were attacks on camps and strong points, and continual harassing of wood-cutting parties obtaining fuel for the locomotives. The artillery was taken out, and trains were shelled. All this, of course, occasioned a fresh wave of Union raids into the home territory of the raiders, during one of which Yank Ames, who had risen to a lieutenancy in the Forty-Third, was killed.
The most desperate efforts were being made, at this time, to keep the Manassas Gap Railroad open, and General C. C. Augur, who had charge of the railroad line at the time, was arresting citizens indiscriminately and forcing them to ride on the trains as hostages. Mosby obtained authorization from Lee's headquarters to use reprisal measures on officers and train crews of trains on which citizens were being forced to ride, and also authority to execute prisoners from Custer's command in equal number to the men hanged at Front Royal and elsewhere.
It was not until November that he was able to secure prisoners from Custer's brigade, it being his intention to limit his retaliation to men from units actually involved in the hangings. On November 6, he paraded about twenty-five such prisoners and forced them to draw lots, selecting, in this manner, seven of them—one for each of the men hanged at Front Royal and another for a man named Willis who had been hanged at Gaines' Cross Roads several weeks later. It was decided that they should be taken into the Shenandoah Valley and hanged beside the Valley Pike, where their bodies could serve as an object lesson. On the way, one of them escaped. Four were hanged, and then, running out of rope, they prepared to shoot the other two. One of these got away during a delay caused by defective percussion caps on his executioner's revolver.
A sign was placed over the bodies, setting forth the reason for their execution, and Mosby also sent one of his men under a flag of truce to Sheridan's headquarters, with a statement of what had been done and why, re-enforced with the intimation that he had more prisoners, including a number of officers, in case his messenger failed to return safely. Sheridan replied by disclaiming knowledge of the Front Royal hangings, agreeing that Mosby was justified in taking reprisals, and assuring the Confederate leader that hereafter his men would be given proper treatment as prisoners of war. There was no repetition of the hangings.
By this time the Shenandoah Valley campaign as such was over. The last Confederate effort to clear Sheridan out of the Valley had failed at Cedar Creek on October 19, and the victor was going methodically about his task of destroying the strategic and economic usefulness of the valley. How well he succeeded in this was best expressed in Sheridan's own claim that a crow flying over the region would have to carry his own rations. The best Mosby could do was to launch small raiding parties to harass the work of destruction.
By the beginning of December, the northern or Loudoun County end of Mosby's Confederacy was feeling the enemy scourge as keenly as the valley, and the winter nights were lighted with the flames of burning houses and barns. For about a week, while this was going on, Mosby abandoned any attempt at organized action. His men, singly and in small parties, darted in and out among the invaders, sniping and bushwhacking, attacking when they could and fleeing when they had to, and taking no prisoners. When it was over, the northern end of Mosby's Confederacy was in ashes and most of the people had "refugeed out," but Mosby's Rangers, as a fighting force, was still intact. On December 17, for instance, while Mosby was in Richmond conferring with General Lee, they went into the valley again in force, waylaying a column of cavalry on the march, killing and wounding about thirty and bringing off 168 prisoners and horses.
When Mosby came back from Lee's headquarters, a full colonel now, his brother William was made a lieutenant-colonel, and Richards became a major. The southern, or Fauquier County, end of Mosby's Confederacy was still more or less intact, though crowded with refugees. There was even time, in spite of everything, for the wedding of the Forty-Third's armorer, Jake Lavender, with John and Jimmy Edmonds' sister.
While the wedding party was in progress, a report was brought in to the effect that Union cavalry were in the neighborhood of Salem, a few miles away. Mosby took one of his men, Tom Love, a relative of one of the Front Royal victims, and went to investigate, finding that the enemy had moved in the direction of Rectortown, where they were making camp for the night. Sending a resident of the neighborhood to alert Chapman and Richards for an attack at daybreak, Mosby and Love set out to collect others of his command.
By this time, it was dark, with a freezing rain covering everything with ice. Mosby and Love decided to stop at the farm of Ludwell Lake for something to eat before going on; Love wanted to stay outside on guard, but Mosby told him to get off his horse and come inside. As they would have been in any house in the neighborhood, Mosby and his companion were welcomed as honored guests and sat down with the family to a hearty meal of spareribs.
