" The armies of Europe are machines; the men are brave and the officers capable; but the majority of the soldiers in most of the nations of Europe are taken from a class of people who are not very intelligent and who have very little interest in the contest in which they are called upon to take part. Our armies were composed of men who were able to read, men who knew what they were fighting for, and could not be induced to serve as soldiers, except in an emergency when the safety of the nation was involved, and so necessarily must have been more than equal to men who fought merely because they were brave and because they were thoroughly drilled and inured to hardships.
