"To thee old cause! Thou peerless, passionate, good cause, Thou stern, remorseless, sweet idea, Deathless throughout the ages, races, lands, After a strange sad war, great war for thee, (I think all war through time was really fought, and ever will be really fought, for thee,) These chants for thee, the eternal march of thee."
January 1, 1970
