Countless deeds of heroism were performed by Northerner and by Southerner, by officer and by private, in every year of the great struggle. The immense majority of these deeds went unrecorded, and were known to few beyond the immediate participants. Of those that were noticed it would be impossible even to make a dry catalogue in ten such volumes as this. All that can be done is to choose out two or three acts of heroism, not as exceptions, but as examples of hundreds of others. The times of war are iron times, and bring out all that is best as well as all that is basest in the human heart. In a full recital of the civil war, as of every other great conflict, there would stand out in naked relief feats of wonderful daring and self-devotion, and, mixed among them, deeds of cowardice, of treachery, of barbarous brutality. Sadder still, such a recital would show strange contrasts in the careers of individual men, men who at one time acted well and nobly, and at another time ill and basely. The ugly truths must not be blinked, and the lessons they teach should be set forth by every historian, and learned by every statesman and soldier; but, for our good fortune, the lessons best worth learning in the nation's past are lessons of heroism.
