The natural way to invest and capture so strong a place, defended and fortified as Vicksburg was, would have been, if the axioms of the art of war had been adhered to, by a system of gradual approaches. A strong base should have been established at Memphis, and then the army and the fleet moved gradually forward, building storehouses and taking strong positions as they went. To do this, however, it first would have been necessary to withdraw the army from the positions it then held not far above Vicksburg, on the western bank of the river. But such a movement, at that time, would not have been understood by the country, and would have had a discouraging effect on the public mind, which it was most essential to avoid. The elections of 1862 had gone against the government, and there was great discouragement throughout the North. Voluntary enlistments had fallen off, a draft had been ordered, and the peace party was apparently gaining rapidly in strength. General Grant, looking at this grave political situation with the eye of a statesman, decided, as a soldier, that under no circumstances would he withdraw the army, but that, whatever happened, he would "press forward to a decisive victory." In this determination he never faltered, but drove straight at his object until, five months later, the great Mississippi stronghold fell before him.
