The study will inevitably deal far more with Union transportation systems than with Confederate transport, not by design but by necessity. The Federal logistical system was far larger, far more successful, and far better documented than its counterpart in the South. The Civil War historian is blessed with a deluge of reports and other documents thoroughly explaining how the four systems worked in the Union war effort. In contrast, the Confederates had far less access to the resources of all four systems.They did not make good use of what access they had, nor did they appoint a quartermaster officer to superintend river transportation and produce reports of what was accomplished. The officers appointed to supervise rail transportation did not have authority to actually change practices and did not file reports of their work. There is only slim evidence that the Confederates used coastal shipping, and they were chronically short of wagons in every theater of the war.
