 The Union victory at Rich Mountain gave the Union Army control of the S-P turnpike, of the Tygart's Valley, the covered bridge at Philippi, and of all of the territory of western Virginia to the north and west, including the B&O railroad.The harsh winter conditions in the mountain climate convinced the leaders of both armies to move on, and they were soon involved in Stonewall Jackson's Valley campaign.The region essentially remained under Union control for the remainder of the War.
