Going to the vicinity of Berryville, he came to a burning farmhouse, and learned that it had been fired only a few minutes before by some of Custer's cavalry. Leaving a couple of men to help the family control the fire and salvage their possessions, he pressed on rapidly. Here was the thing every Mosby man had been hoping for--a chance to catch house burners at work. They passed a second blazing house and barn, dropping off a couple more men to help fight fire, and caught up with the incendiaries, a company of Custer's men, just as they were setting fire to a third house. Some of these, knowing the quality of mercy they might expect from Mosby men, made off immediately at a gallop. About ninety of them, however, tried to form ranks and put up a fight. The fight speedily became a massacre. Charging with shouts of "No quarters!", Chapman's men drove them into a maze of stone fences and killed about a third of them before the rest were able to extricate themselves. This didn't stop the house burnings, by any means. The devastation of the Shenandoah Valley had been decided upon as a matter of strategy, and Sheridan was going through with it. The men who were ordered to do the actual work did not have their morale improved any by the knowledge that Mosby's Rangers were refusing quarter to incendiary details, however, and, coming as it did on the heels of the wagon train affair of the 13th, Sheridan was convinced that something drastic would have to be done about Mosby. Accordingly, he set up a special company, under a Captain William Blazer, each man armed with a pair of revolvers and a Spencer repeater, to devote their entire efforts to eliminating Mosby and his organized raiders. On September 3, this company caught up with Joe Nelson and about 100 men in the valley and gave them a sound drubbing, the first that the Mosby men had experienced for some time. It was a humiliating defeat for them, and, on the other side, it was hailed as the beginning of the end of the Mosby nuisance. A few days later, while raiding to the east of Bull Run Mountain, Mosby was wounded again, and was taken to Lynchburg. He was joined by his wife, who remained with him at Lynchburg and at Mosby's Confederacy until the end of the war.
