After my foreign education, with my reserved temper, I should long have continued a stranger in my native country, had I not been shaken in this various scene of new faces and new friends; had not experience forced me to feel the characters of our leading men, the state of parties, the forms of office, the operations of our civil and military system.

In this peaceful service I imbibed the rudiments of the language and science of tactics, which opened a new field of study and observation.

I diligently read and meditated the _Memoires Militaires_ of Quintus Icilius, the only writer who has united the merits of a professor and a veteran.

The discipline and evolution of a modern battalion gave me a clearer notion of the phalanx and the legion, and the captain of the Hampshire grenadiers (the reader may smile) has not been useless to the historian of the Roman Empire." No one can doubt it who compares Gibbon's numerous narratives of military operations with the ordinary performances of civil historians in those matters.

The campaigns of Julian, Belisarius, and Heraclius, not to mention many others, have not only an uncommon lucidity, but also exhibit a clear appreciation of the obstacles and arduousness of warlike operations, which is rare or unknown to non-military writers.
