From a very early age he was fascinated with the
railroad, becoming an engineer and machinist in his youth, and
was remembered for his dare-deviltry at the throttle.
In 1862, at the age of 41, he enlisted with the
Confederate Army as a member of the new Independent Signal Corps,
but by war's end he was in charge of the Commissary Department
of southeastern Virginia.
His wife and family took refuge in Dublin, Pulaski
County, during the war, but were forced to leave in the spring
of 1865, as his son remembered, in a hail of Yankee bullets.
His son told the story that John returned to Portsmouth
after the war in a coach with 11 other men. The driver elected
to charge his passengers by weight -- John proved the heaviest
at 299 pounds. Apparently being comissary officer had its advantages.
