Another reason for his change of sentiment was his fortunate marriage to a lady whom he met at Rennes, where his regiment was stationed—Mademoiselle Julie Bienvenue. Her name means "Welcome," and to the lonely and possibly homesick soldier, her advent must have been welcome indeed.

He bought a home in Finisterre, that wild, rocky, well-wooded cape which juts out into the Atlantic. It was an old manor house set in the midst of an estate which from the outset spelled the word "home" for him. There were long sloping meadow lands flanked by stately trees and hills beyond. The old house itself with its somber gray walls and quaint dormer windows seemed always to have nestled here.

Such an idyllic setting, away out on the most sheltered spot of France—far removed from the tramp of an invader, or the other changes which came to the central provinces of France—while pleasant in the extreme was hardly the fitting environment to produce a soldier, a real fighting man. It might produce a fine preacher, or artist, or poet, or farmer—but not likely a famous general.

But Foch did not yield to the blandishments of his new home to the extent of vegetating here. His active mind was looking continually forward. He could not rest content with mediocrity, or a merely comfortable living. "Do what you ought, come what may" was his guiding motto. He applied for admission to the École de Guerre, a higher school recently established for staff officers, but admission to its walls came by favoritism or political pull, and it was many months (1885) before he gained admission.

The course which he took required two years to complete—years which kept him away from home, but were worth while. He graduated as fourth in a large class, and better still had made some valuable acquaintances here. His professors and classmates soon recognized in this quiet, studious Artillery Captain a man worth watching—one who would do in an emergency.

The next eight or ten years were filled with the usual routine of an army officer in peace times. He was transferred from one post to another for periods of two or three years, but always it was active field service which he liked, rather than the routine of office duty. He established a brilliant reputation for horsemanship and cavalry tactics which later were to be of advantage.

But still he had never seen actual warfare, nor heard the bullets whizz about his head. He was an academic soldier, and seemed destined to remain one for the rest of his natural life when, in 1895, he was appointed Assistant Professor of Military History and Strategy, in the École de Guerre, the college from which he had last graduated, a few years before. The faculty had not forgotten him. It was an honor in a way, but Foch doubtless debated long before he accepted it. It meant the giving up of the freedom of his broad outdoors.

He was a major by this time; and after a few years of lecturing, he was made full professor, with the rank of Lieutenant Colonel. The work in his classes was highly important. This being a post-graduate school, the men to whom he lectured were not cadets but trained soldiers, many of them seasoned veterans. They would have instantly detected any flaw in his teaching. The impress which this college professor then made upon the future heads of the French army was destined to have a profound and far-reaching effect. In the years to come, when France and the civilized world was in search of a leader big enough to measure up to the crisis—they turned to this quiet college professor!

Foch won his position as "the most gifted and original of the professors in the École de Guerre" by no trick or sensational methods. He spoke in an even, almost monotonous voice, using few gestures. But his speech was clear-cut and precise. He reminded his hearers of a scientist dissecting a foreign body, as he expounded the clash of armies or the turning points of battle. He had, in fact, precise knowledge of an event in which he had never actually participated. He had analyzed war and resolved it into its component parts, as though it were heated in a test-tube. And how exact were his theories, later events were to show.

In 1901, Foch returned for a time to active service, being given command of the 29th Regiment at Laon. After the classroom routine, the change was indeed welcome. A few months later we find him stationed again in his beloved Brittany, with the rank of Colonel. But promotion had come slowly. During these years he prepared his class lectures for book publication, forming two volumes, the first being his since-celebrated "Principles of War," and the second "The Conduct of War." In these books he proved himself a master of terse, epigrammatic statement. There did not seem to be a superfluous word in them. They were favorably received by military critics everywhere, and still further established his reputation.
