The cannon of the communards, set on the heights of Pere-Lachaise (the great city of the dead where the slumber of so many of earth’s most illustrious imposed no respect upon the “Bolsheviki” of that cataclysm) aimed at the Pantheon, shot short and struck the Polytechnic.  One shell burst in the midst of an improvised hospital there, gravely wounding a nurse.

At last, on May 24, the Polytechnic was taken from the revolutionists by assault, and many of the communards were seized.

In the days following, the great recreation court of the school was the scene of innumerable executions, as the wretched revolutionists paid the penalty of their crimes before the firing squad.  And the students’ billiard room was turned into a temporary morgue, filled with bodies of those who had sought to destroy Paris from within.

The number of Parisians slain in those days after the second siege of Paris has been variously estimated at from twenty thousand to thirty-six thousand.  And all the while, encamped upon the heights round about Paris, were victorious German troops squatting like Semitic creditors in Russia, refusing to budge till their account was settled to the last farthing of extortion.

The most sacred spot in Paris to young Foch, in all the depression he found there, was undoubtedly the great Dome des Invalides, where, bathed in an unearthly radiance and surrounded by faded battle flags, lies the great porphyry sarcophagus of Napoleon I.

With what bitter reflections must the young man who had been nurtured in the adoration of Bonaparte have returned from that majestic tomb to the Polytechnic School for Warriors—­to which, on the day after his coronation as Emperor, Napoleon had given the following motto: 

“Science and glory—­all for country.”

But, also, what must have been the young southerner’s thought as he lifted his gaze on entering the Polytechnic and read there that self-same wish which was inscribed over the door of his first school in Tarbes: 

“May this house remain standing until the ant has drunk all the waves of the sea and the tortoise has crawled round the world.”

The edifice in which part of the Polytechnic was housed was the ancient College of Navarre, and a Navarrias poet of lang syne had given to the Paris school for his countrymen this quaint wish, repeated from the inscription he knew at Tarbes.

France had had twelve different governments in fourscore years when Ferdinand Foch came to study in that old building which had once been the college of Navarre.  Houses of cards rather than houses of permanence seemed to characterize her.

Yet she has always had her quota—­a larger one, too, than that of any other country—­of those who look toward far to-morrows and seek to build substantially and beautifully for them.

That forward-looking prayer of old Navarre, and recollection of the centuries during which it had prevailed against destroying forces, was undoubtedly an aid and comfort to the heavy-hearted youth who then and there set himself to the study of that art of war wherewith he was to serve France.
