T. H. Campbell telegraphed Governor John Letcher from Petersburg on April 18, 1861, to announce the arrival of a company of volunteers from Nottoway County. The governor received dozens of telegrams and letters similar to this during the second half of April 1861. The notation "DHK" may have been by the telegraph operator.
