"It cost about 75 cents to kill a man in Ceasar's time. The price rose to about $3,000 per man during the Napoleonic wars; to $5,000 in the American Civil War; and then to $21,000 per man in World War I. Estimates for the future wars indicate that it may cost the warring countries not less than $50,000 for each man killed."

What a general could do, Thomas did; no more dependable soldier for a moment of crisis existed on the North American continent, or ever did exist... Thomas comes down in history as the Rock of Chickamauga, the great defensive fighter, the man who could never be driven away but who was not much on the offensive. That may be a correct appraisal, Yet it may also be worth making note that just twice in all the war was a major Confederate army driven away from a prepared position in complete rout - at Chattanooga and at Nashville. Each time the blow that routed it was launched by Thomas.
