On March 24, 1865, Union Gen. George Stoneman led 6,000 cavalrymen from Tennessee into southwestern Virginia and western North Carolina to disrupt Confederate supply lines by destroying sections of the Virginia and Tennessee Railroad, the North Carolina Railroad, and the Piedmont Railroad; he struck Boone on March 28, entered Virginia on April 2, returned to North Carolina a week later, and ended the raid at Asheville on April 26, the day Confederate Gen. Joseph E. Johnston surrendered to Union Gen. William T. Sherman near Durham. Early in April, a detachment of Stoneman's cavalry rode south from Jonesville to Hamptonville and passed through Windsor's Crossroads, where Alfred "Teen" Blackburn, then enslaved, later recalled the Union cavalry riding "three abreast" on the narrow dirt road in front of his house and reported that the Federals burned everything along the way, including Buck Shoals Mill about two miles north. Colvin J. Cowles wrote to his son on April 6 that after burning the mill, Stoneman's men continued into Iredell County to burn Eagle Mill, passing through Windsor's Crossroads en route. More than twenty Confederate veterans are buried in the Flat Rock Baptist Church cemetery about four miles northeast; the church was founded in 1783 as Petty's Meetinghouse. Those buried there include Yadkin County natives Capt. James West, killed in 1863 in the skirmish at Bond Schoolhouse, and Robert Duvall, who served as a lieutenant in the U.S. Navy until 1859 and then as captain of the small Confederate steamer Beaufort. On July 21, 1861, Duvall and Beaufort engaged USS Albatross off the North Carolina coast near Cape Hatteras, and Duvall claimed victory in one of the Civil War's earliest all-naval battles. John A. Hampton, grandson of Hamptonville founder Henry Hampton, began practicing law in Wilkesboro in 1858, volunteered in the Wilkes Valley Guards of the 1st Regiment North Carolina Infantry, resigned because of bad health in September 1863, later served as an officer in Yadkin County's 74th Regiment North Carolina Militia, and is buried in Flat Rock Church cemetery. In January 1862, 18-year-old Alfred "Teen" Blackburn accompanied Pvt. John Augustus Blackburn to Camp Mangum, where the soldier served in Co. F, 21st North Carolina Infantry, and Alfred Blackburn served as his bodyguard, cook, and helper, later receiving a pension of $26.26 per month; his brother Wiley Blackburn was a body servant in Company B, 38th North Carolina Infantry. After the war, Alfred Blackburn worked as a mail carrier for sixty years on routes from Hamptonville to Jonesville and then to Statesville, died in 1951, was believed to be the last surviving participant in the war in the state, and was buried at nearby Pleasant Hill Baptist Church in Iredell County.
