Corinth is a little village in the extreme north of Mississippi. It has no pronounced defensive advantages whatsoever. It lies in a region of nearly flat lands with no line of bold hills to protect it and no difficult stream to serve as a base of defense. But it lies upon that line of railroad which the Confederates must defend if they were to preserve their communications between the east and the west at the crossing of the north and south line. At Corinth the Confederates concentrated all their forces. Against Corinth Grant instantly directed his operations as soon as he was restored to command and permitted by his superior officer to carry on the war for his country upon lines marked out by common-sense. He moved at once to Pittsburg Landing on the Tennessee river. Pittsburg Landing lies about twenty miles north by east of Corinth and between the two there is no considerable stream, no important range of hills, nothing in the shape of physical conformation of the ground that could aid Confederate defense or facilitate Confederate aggression. On the contrary the streams near Pittsburg ministered exclusively to Federal purposes. When Grant arrived at Pittsburg Landing he found the army encamped about equally upon the eastern and western sides of the river. He instantly and boldly ordered the whole of it to the western or Confederate bank of the stream. This was a very daring thing to do. For with the Tennessee river behind him and with no means of easily crossing it in retreat, Grant must face the certain surrender of his army in case of an unsuccessful battle in that position. In such an event there could be no alternative. But it was not Grant's habit of mind to look for alternatives. He boldly took the risk as it was his custom to do. He threw his whole army across the river and there waited for the arrival of Buell's stronger force, which had been ordered by Halleck to join him and was marching in very leisurely fashion to do so. The army under Grant's own immediate command numbered now about 38,000 men, increased almost immediately to 45,000. That under Buell which was strolling westward to reinforce him numbered more than 40,000. He thus had prospect of an overwhelming force with which to assail the Confederates at Corinth, where under Beauregard's tireless activity they had succeeded in concentrating about 45,000 or 50,000 men, a large part of this force consisting of raw recruits unorganized, undrilled, undisciplined and extremely ill armed.
