Another element of the highest importance had also entered into the problem with which the nation was struggling. This was the appointment (January 21, 1862) of Edwin M. Stanton to succeed Simon Cameron as Secretary of War. Mr. Stanton, then forty-seven years of age, was a lawyer by profession, a man of great intellect, unfailing nerve, and tremendous energy. He had certain traits that often made him personally disagreeable to his subordinates; but it was impossible to doubt his thorough loyalty, and his determination to find or make a way to bring the war to a successful close as speedily as possible, without the slightest regard to the individual interests of himself or anybody else. He was probably the ablest war minister that ever lived--with the possible exception of Carnot, the man to whom Napoleon said, "I have known you too late." It is indicative of Mr. Lincoln's sagacity and freedom from prejudice, that his first meeting with Mr. Stanton was when he went to Cincinnati, some years before the war, to assist in trying an important case. He found Mr. Stanton in charge of the case as senior counsel, and Stanton was so unendurably disagreeable to him that he threw up the engagement and went home to Springfield. Yet he afterward gave that man the most important place in his cabinet, and found him its strongest member. One division of the army embarked on the 17th of March, and the others followed in quick succession. General McClellan reached Fort Monroe on the 2d of April, by which time fifty-eight thousand men and one hundred guns had arrived, and immediately moved with this force on Yorktown, the place made famous by the surrender of Cornwallis eighty years before. The Confederates had fortified this point, and thrown a line of earthworks across the narrow peninsula to the deep water of Warwick River. These works were held by General Magruder with thirteen thousand effective men. General Johnston, who was in command of all the troops around Richmond, says he had no expectation of doing more than delaying McClellan at Yorktown till he could strengthen the defences of the capital and collect more men; and that he thought his adversary would use his transports to pass his army around that place by water, after destroying the batteries, and land at some point above.
