The 62nd Regiment Mounted Infantry completed its organization in September, 1862. The unit was composed of infantry and cavalry until December when the cavalry companies united with other companies to form the 18th Regiment Virginia Partisan Rangers, and at times the 62nd Partisan Rangers, the 62nd Infantry, and Imboden's Partisan Rangers. The command was mounted during the latter part of 1863 and served in Imboden's Brigade. Disbanded in April, 1865. Its commanders were Colonels John D. Imboden and George H. Smith, Lieutenant Colonels Robert L. Doyle and David B. Lang, and Majors Houston Hall and George W. Imboden.
Companies in this Regiment with the Counties of Origin:
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first.
Company A (Valley Rifles) - many men from Augusta and Highland Counties
Company B ( Hardy Blues) - many men from Hardy County
Company C. - many men from Pendleton County
Company D - many men from Pendleton County
