In the meantime, more serious work turned up. The regiment of the cadets was sent against the Germans, entered Mouzon, was besieged there. In a sortie, Cyrano was seriously wounded, a musket-ball passing through his body. Hardly recovered from his wound, he rejoined the army at the siege of Arras, in 1640; unfortunately for the story, he was probably no longer with the cadets there, but in the regiment of the Prince de Conti. Again he was wounded, this time even more seriously, with a sword-cut in the throat. And compelled to abandon the military career, he returned to Paris and took up his studies and his writing. For he had always been a student and a poet. It is probable that the _Pédant joué_ was in part composed during his college days. Lebret pictures him to us as studying between two duels, and working at an Elegy in all the noise of the regimental barracks, "as undistractedly as if he had been in a quiet study." He now joined a group of independents in thought and life, naturalists in ethics and empiricists in philosophy, and forced his way into a private class of the philosopher Gassendi, where he had for fellow-students Hesnaut, Chapelle, Bernier, and almost certainly a young Jean-Baptiste Poquelin, who was very soon to take the name of Molière, found the "Illustre Théâtre," and after its failure start on a fifteen years' tour of the provinces. Cyrano was an earnest and capable student of philosophy, and came to it with the fresh interest not only of his own personality, but of a young man of barely twenty-two; he naturally imposed himself as a sort of leader in the group of young "libertins" or free-thinkers, just as he had done among the Guards. He knew well not only Gassendi, but also Campanella, and of course Descartes, in his works at least. He even seems to have read widely among the half-philosophers, half-occultists of the fifteenth and early sixteenth centuries, such as Cornelius Agrippa, Jerome Cardan, Abbot Tritheim, César de Nostradamus, etc. Among the ancients, his first favorites were Lucretius and Pyrrho: Pyrrho whom he especially admired, "because he was so nobly free, that no thinker of his age had been able to enslave his opinions; and so modest, that he would never give final decision on any point." There is much of Cyrano in this phrase, both in the half-bold modesty and in the half-timid fierceness of independence. Cyrano shuddered at the thought of having even a single one of his ideas enslaved to those of another thinker. Just as he had refused the Maréchal de Gassion for patron when he was in the Guards, so he would accept no one's _magister dixit_, no patron of his thought, not even the Aristotle of the Schools.
