Its purpose ... is to tell in simple fashion the story of some Americans who showed that they knew how to live and how to die; who proved their truth by their endeavor; and who joined to the stern and manly qualities which are essential to the well-being of a masterful race the virtues of gentleness, of patriotism, and of lofty adherence to an ideal.

It is a good thing for all Americans ... to remember the men who have given their lives in war and peace to the service of their fellow-countrymen, and to keep in mind the feats of daring and personal prowess done in time past by some of the many champions of the nation in the various crises of her history.
