After his heroic actions at the First Battle of Kernstown near Winchester Virginia, March 23, 1862, Casement was appointed colonel of the newly formed 103rd Ohio Volunteer Infantry and fought in the operations around Knoxville.

Casement's commanding officer, Jacob D. Cox, credited him with "saving the day for the Union.

Daniel T. Casement (1834 - 1881)[11][12] was responsible for financing the operations, while John directed the construction crews who took to calling their boss "General Jack."

The brothers oversaw the construction from Fremont, Nebraska, to the railroad's completion at Promontory, Utah.

In the series, the character of Cullen Bohannon (portrayed by Anson Mount) is loosely modeled on Casement's life and career.
