Results of the Battle Longstreet corps detached to Knoxville Didn’t destroy the Army of the Cumberland. Didn’t liberate any territory lost that summer. Did stop advance towards Atlanta. And a morale boost after a terrible summer. . .
Deployment The “Flanks” Theoretically there were around 100 men in each of 10 companies— around 1000 men. In reality, there were usually much less. Flags played a key role in the regiment.

The Theoretical Arithmetic of Logistics requires 3 pounds of food per day (not incl. water). The daily individual ration for a Union soldier: 20 ounces of fresh or salt beef or 12 ounces of pork or bacon 1 pound of hard bread or 18 ounces of flour or 20 of cornmeal. Additionally per every 100 men: 15 pounds of beans or peas 10 pounds of rice or hominy 10 pounds of green coffee or 1.5 pounds of tea 15 pounds of sugar 4 quarts of vinegar 3.75 pounds of salt 4 ounces of pepper 30 pounds of potatoes when practicable, 1 quart of molasses. Approximately: 3,000 calories.
Water and railroad supply allowed your army to look like this … 10,000 men 100,000 men rather than this!
There are roughly 9,500 miles of rail lines in the Confederacy.
As far as a logistician is concerned the advantages of railroads are legion. Can you think of any? Advantages: CAPACITY A Civil War-era railcar could carry as much as 15 tons. One 10-car train could carry as many supplies as 150 wagons. SPEED A train traveled 5 times faster than a wagon train, which meant more round trips and that fewer resources needed to be devoted to supply services. DEPENDABILITY Anyone who has ever dealt with mules will tell you they have a mind of their own. Enough said! AVAILABILITY More rolling stock and locomotives could be produced on demand and in different models. This doesn’t apply to mules and horses!
As good as railroads were for supply, knowledgeable commanders, especially Union ones, preferred supply lines based on water transport. Can you think of two reasons why? SECURITY “We are much obliged to the Tennessee [River] which has favored us most opportunely, for I am never easy with a railroad which takes a whole army to guard, each foot of rail is essential to the whole; whereas, they can’t stop the Tennessee … .” General William Tecumseh Sherman, “Sinews of War” CAPACITY An ordinary Ohio River steamboat of 500 tons carried enough supplies to supply an army of 40,000 men and 18,000 horses for nearly two days. This was the equivalent of five 10-car freight trains.
The past is a foreign country . . . Why use military history? Tactics: critical thinking, relationship between technology and tactics Personalities: politics, leadership, irony Battle: critical thinking, results– battle the arbiter Document based research and questions: Defend or refute Bragg’s statement that if it were not for the loss of these four hours (on 20 Sept), "our independence might have been won.” Battle analysis: Students assigned role of commanders Discuss what they knew, what they thought they knew, and their decisions on a map.
