Willis J. Abbot,
Aircraft and Submarines
“ The submarine has exerted upon the progress of the war an influence even more dominant than that of aircraft. It has been a positive force both offensive and defensive. It has been Germany's only potent weapon for bringing home to the British the privations and want which war entails upon a civilian population, and at the same time guarding the German people from the fullest result of the British blockade. It is no overstatement to declare that but for the German submarines the war would have ended in the victory of the Allies in 1916. ”
