As the siege of Petersburg began, Union cavalry generals James H. Wilson and August V. Kautz led their men on a long railroad raid, June 22–30, 1864. They disrupted rail traffic temporarily, but at a heavy cost. Today you can follow the Wilson-Kautz Raid route from Dinwiddie, just off U.S. Route 1, through Confederate-held territory and back to Union lines. Colorful markers along the way interpret key stops at combat sites and other interesting places.
