On April 20, 1863, Confederate Gens. William E. "Grumble" Jones and John D. Imboden began a raid from Virginia through present-day West Virginia on the Baltimore and Ohio Railroad. Taking separate routes, they later reported that they marched 1,100 miles, fought several engagements, captured 700 Federals, seized about 1,200 horses and 4,000 cattle, and burned 4 turnpike bridges, more than 20 railroad bridges, 2 trains, and 150,000 barrels of oil. Most bridges were soon repaired, Confederate losses were slight, and by May 26 both commands had returned to Virginia's Shenandoah Valley. On April 26, 1863, Confederate Gen. William E. Jones and his cavalrymen arrived on the Northwestern Turnpike from Grant County facing the Cheat River covered bridge. Jones divided his force, sending a hundred-man detachment over Palmer's Knob to descend into Rowlesburg and burn the Baltimore and Ohio Railroad Bridge in the middle of town, while another mounted detachment moved downstream to attack the town from another direction. He considered burning the wooden bridge but was persuaded to preserve one lane and tear up the other in case he needed to retreat over it. Four miles downstream in Rowlesburg, Union Maj. John Showalter commanded a garrison of fewer than 300 men, and with them and a number of armed townspeople he thwarted Jones's attempt to burn the railroad bridge, after which Jones moved on toward Fairmont. Had the Confederates succeeded at Rowlesburg, a vital link between the Ohio River and the Army of the Potomac in the east would have been cut for months, worsening Federal difficulties in moving troops and materiel through West Virginia. The Cheat River covered toll bridge was a two-lane, 339-foot-long bridge completed in 1835 on the Northwestern Turnpike. Its designer, Lewis Wernwag, sublet the construction to Josiah Kidwell, who was paid $18,000. The turnpike was an important avenue for commerce and was essential for troop movement during the Civil War. After Jones's men removed the flooring from one lane of the bridge, it was not replaced until after the war. In 1932, the bridge was declared a state relic. Vehicular traffic ceased in 1934 when a steel span bridge was built just downstream, and vandals burned the covered bridge on May 23, 1964.
