and I here received a dispatch from General Lee, directing me to
remain in the lower Valley until everything was in readiness to
cross the Potomac, and to destroy the Baltimore and Ohio railroad
and the Chesapeake and Ohio Canal as far as possible. This
was in accordance with my previous determination, and its
policy was obvious. My provisions were nearly exhausted
and it I had moved through Loudon, it would have been necessary for me to halt and thresh wheat and have it ground, as
neither bread nor flour could be otherwise obtained; which

On the night of the 2nd, McCausland was sent across North Mountain, to move down Back Creek, and burn the railroad bridge at its mouth, and then to move by North Mountain depot to Haynesville, on the road from Martinsburg lo Williamsport; and, early on the morning of the 3rd, Bradley Johnson was sent by Smithfield and Leetown, to cross the railroad at Kearneysvilie, east of Martinsburg, and unite with McCausland, at Haynesville, so as to cut off the retreat of Sigel, who was at Martinsburg with a considerable force. Breckenridge moved, on the same morning, direct for Martinsburg, with his command preceded by Gilmor's battalion of cavalry, while I moved, with Rodes' and Ramseur's divisions, over the route taken by Johnson, to Leetown. On the approach of Breckenridge, Sigel, after very slight skirmishing, evacuated Martinsburg, leaving behind considerable stores, which fell into our hands. McCausland burned the bridge over Back Creek, captured the guard at North Mountain depot, and succeeded in reaching Haynesville; but Johnson encountered a force at Leetown, under Mulligan, which, after hard fighting, he drove across the railroad, when, Sigel having united with Mulligan, Johnson's command was forced back, just before night, on Rodes' and Ramseur's divisions, which had arrived at Leetown, after a march of twenty-four
