On March 26, 1862, at Miss Stover’s stone house near Narrow Passage Creek, Jedediah Hotchkiss met with Gen. Thomas J. “Stonewall” Jackson three days after the defeat of Jackson’s Valley Army at Kernstown, Virginia. After discussing Hotchkiss’s topographical work in northwestern Virginia the previous year, Jackson directed him to make a map of the Valley from Harper’s Ferry to Lexington showing points of offense and defense. Hotchkiss began the task immediately and soon advised Jackson to move the army farther south to Rude’s Hill. His maps and advice proved invaluable during Jackson’s Valley Campaign of 1862. After Jackson’s death, Hotchkiss continued his cartographic work under Gens. Richard S. Ewell and Jubal A. Early. One-half of the Confederate maps published in the Official Atlas of the Civil War are attributed to him, and after the war he became an important source for scholars seeking accurate accounts of the conflict and a respected East Coast lecturer on war topics.
