Among the national leaders whose names will always hold an honorable place in American history is Ulysses S. Grant, the simple-hearted man and capable soldier, to whose patriotism, courage, persistence, and skill was so largely due the successful termination of the war between the States, the contest which assured the foundations of the Republic. We are interested not only in learning what this man did, but in coming to know, as far as may be practicable, what manner of man he was. It is all-important in a study of development of character to have placed within reach the utterances of the man himself. There is no utterance that can give as faithful a picture of a man's method of thought and principle of action as the personal letter written, with no thought of later publication, to those who are near to him.
