In this volume I am going to tell you the story of the war as it unfolded itself during the year 1915. It was a year of life-and-death struggle, during which two other nations were swept by the seething whirlpool into the waters of strife, and eight out of ten persons in the continent of Europe were living under war conditions. It was a year during which the three greatest empires of the world, and seven other Powers, fought fierce and bitter combats on five different battle fronts in Europe alone. It was a year in which some millions of men fell on the stricken field, and yet the issue of the vast and terrible struggle remained undecided. It was a year in which the Allies, who were quite unready when war was forced upon them, strained every nerve to set their military houses in order; to enlist and train for the field their reserves of manhood; and to furnish themselves with those weapons and munitions in which they were deficient. It was a year in which millions of hard-earned money were spent every day, and the combatants piled up mountains of debt for future generations to pay off.
