and Harrisonburg yesterday morning. The grain and forage in advance of these points up to Staunton had previously been destroyed. In moving back to this point the whole country from the Blue Ridge to the North Mountains has been made untenable for a rebel army. I have destroyed over 2,000 barns, filled with great, hay, and farming implements; over 70 mils, filled flour wheat; have driven in front of the army over 4[000] head of stock, and have killed and issued to the troops not less than 3,000 sheep. This destruction embraces the Luray Valley and Little Fort Valley, as well as the main valley. A large number of horses have been obtained, a proper estimate of which I cannot now make. Lieutenant John R. Meigs, my engineer officer, was murdered beyond Harrisonburg, near Dayton. For this atrocious act all the houses within an area of five miles were burned. Since I came into the Valley, from Harper's Ferry up to Harrisonburg every train, every small party, and every straggler has been bushwhacked by people, many of whom have protection papers from commanders who have been hitherto in this valley. From the vicinity of Harrisonburg over 400 wagon loads of refugees have been sent back to Martinsburg; most of these people were Dunkers, and had been conscripted. The people here are getting sick of the war; heretofore they have had no reason to complain, because they have been living in great abundance. I have not been followed by the enemy up to this point, with the exception of a small force of rebel cavalry that showed themselves some distance behind my rear guard to-day. A party of 100 of the Eighth Ohio Cavalry, which I had stationed at the bridge over the North Shenandoah, near Mount Jackson, was attacked by McNeil, with seventeen men; report they were asleep, and the whole party dispersed or captured. I think that they will turn up. I learned that fifty-six of them have reached Winchester. McNeil was mortally wounded and fell into our hands. This was fortunate, as he was the most daring and dangerous of all the bushwhackers in this section of the country. I would have preferred sending troops to you by the Baltimore and Ohio Railroad; it would have been the quickest and most concealed way of sending them. The keeping open of the road to Front Royal will require large guards to protect it against a very small number of partisan troops; it also obliges me to have a pontoon train, if it is to be kept open, to bridge the Shenandoah, and keep up communication with Winchester. However, in a day or two I can tell better. I sent a party of cavalry through Thornton's Gap, and directed the balance of the division of cavalry which I have left in the Valley to take position at Millwood, occupying Chester Gap and Front Royal. Thornton's Gap I have given up, as of no value. With this disposition of forces, I will move infantry round the mountains, via Strasburg, as soon as possible. To-morrow I will continue the destruction of wheat, forage, &c., down to Fisher's Hill. When this is completed the Valley, from Winchester up to Staunton, ninety-two miles, will have but little in it for man or beast. In previous dispatches I have used "lower Valley" when I should have said "upper Valley," or, in other words, in my last dispatch I intended to say that the grain and forage from Staunton up to Lexington had been sent to Richmond, and that the grain and forage from Staunton to Strasburg had been left for the wintering of Early's army. Yesterday Colonel Powell captured a guerrilla camp on the mountains, with ten wagons and teams.
