Robert Silliman Hillyer - "How oft the traitor trumpet sounds retreat" lyrics

How oft the traitor trumpet sounds retreat, Beguiling my bewildered soul again, When all the forces on the battle-plain Are ready to do homage at my feet; And when I fight with strength, it is in vain, For then I find no foe before my eyes, They lurk in shadow, waiting to surprise My soul when it is weary and in pain. How shall I gauge the conflict and the odds, Misled and blinded in the midst of strife? How shall I know mine enemy? O gods, Grant me one moment worthy of my life, To see at last beyond the dust and shade, And face real foemen, strong and unafraid.
