Following the Battle of Cloyd's Mountain in 1864, during the American Civil War (1861–1865), Union General George Crook marched his troops over to the present day town of Union, WV, via Salt Pond Mountain. Then, in 1869, following the Civil War, the hotel and its properties were sold to General and Mrs. Herman Haupt. Haupt had been head of the United States Military Railroad during the War. During their first year of ownership, though not operating publicly, the Haupts received compensation from some of their guests for the accommodations provided, prompting Giles County to require them to purchase a hotel license. Subsequently, they decided to re-open the hotel to the general public. Due to the resulting popularity of the hotel in this first season, several additions to the hotel were required to meet the increasing demand for more accommodations.
