The Forest of Swords — Joseph Altsheler

John Scott and Philip Lannes walked together down a great boulevard of Paris. The young American's heart was filled with grief and anger. The Frenchman felt the same grief, but mingled with it was a fierce, burning passion, so deep and bitter that it took a much stronger word than anger to describe it. Both had heard that morning the mutter of cannon on the horizon, and they knew the German conquerors were advancing. They were always advancing. Nothing had stopped them. The metal and masonry of the defenses at Liege had crumbled before their huge guns like china breaking under stone. The giant shells had scooped out the forts at Maubeuge, Maubeuge the untakable, as if they had been mere eggshells, and the mighty Teutonic host came on, almost without a check.
