For the present, there was nothing for it, but to doff his uniform and take up his studies again. The college of St. Clement had ceased to be a hospital and was again full of classrooms. But over the old fort floated a strange flag—the black, white and red emblem of Germany, and German officers strutted everywhere on the streets. The French signs over the shops and on the street corners were rapidly disappearing. Soon came an official order from Berlin forbidding the teaching of French in the schools of Alsace and Lorraine. The work of benevolent assimilation was begun.

Foch privately shook his fist at the broad backs of the swaggering conquerors, and set to work at his studies with renewed vim. French or German, the old Jesuit college was going to aid him in his task of becoming a soldier—and then his country would have one more recruit at any rate!

We are not surprised to find, therefore, that he passed his entrance examinations with flying colors, and in November, 1871, donned his uniform as a cadet in the École Polytechnique. This building, like the one at Metz, still bore evidences of the recent war. During the siege of Paris it had been used as a hospital; and in the civil war which followed the peace, when the Empire was overthrown, it had been through severe fighting. Shell holes were still to be seen in its roofs and walls. But such scars seemed to make it still more what it was in name, a military school. Foch already felt like a soldier.

Among Foch's fellow students were two others who were destined to play a part in the World War. One was a cadet named Ruffey, who was destined to become a General, in command of the Third Army of France, during 1914. The other was a short, stocky fellow, who came from the Gascon country near Foch's home, and who had been more fortunate than he in seeing some actual fighting during the recent war. He had been in command of a battery of guns during the siege of Paris, and had also taken a physical part in the fighting. Foch looked at this strapping cadet, and then at his own much slighter frame, and a feeling akin to envy came over him, as he may have said to himself:

"If only I could have got into it like that fellow Joffre!"

During the second year of his work here, in 1873, it was announced that, as the army was short of officers, the course would be shortened for the more advanced students, so that they could receive their commissions as soon as possible. Among the students who were granted this honor were Joffre and Foch—the former choosing the engineers, and the latter the artillery. As a special aid in completing his course, Foch secured a transfer to the Artillery School at Fontainebleau.

Here he felt more at home and in more congenial surroundings. He was out of the city with its clamor and clang. Always a country boy at heart, he recalled his beloved St. Étienne in these parks and hills. He had always been fond of horseback riding, and now he had full opportunity of perfecting himself in this art. The daily canters kept his body sound, his brain clear. He came out third in his classes, a highly creditable mark, and received his commission as a sub-lieutenant. He was a soldier at last.

As a reward for his scholarship he was informed that he might choose any post where he would prefer to be stationed. He selected Tarbes, his birthplace, and the town nearest his home. Truly, the fates were kind!

Two years were spent with the garrison at Tarbes, in a round of regimental duties. Then the routine began to pall upon him. He wanted something approaching active service. He had perfected himself in artillery maneuvers; and during his four months as a volunteer in the War, he had drilled in the infantry. So he now applied for transfer to the third branch, the cavalry. His love of horses may also have influenced this desire.

He received the transfer and spent a year in the Cavalry School at Saumur. On completing this course he was given a commission as Captain, and placed in command of a field battery, in Brittany. This transfer marked the beginning of a new era in his life. From being a Gascon, he was now about to become a Breton. He spent so many years of his life in Brittany, that in later years he called his soldiers "my brother Bretons."
