From A Bibliography of Alexandre Dumas père by Frank Wild Reed: This "Journal of Fancies and of Facts" first appeared on March 2nd, 1848, and lasted until the 16th of June, 1850. In a period so tumultuous it probably devoted more space to facts than to fancies. Baroness Bonde speaks of it as a "rather well-written, violent composition."
Its editor-in-chief was M. Lepoitevin Saint-AIme, assisted by Alexandre Dumas, A. Vitu and A. Pourcy.
Dumas says in his "Le Monte-Cristo" : "I had then an engagement with the journal 'La Liberté.' I had joined it in the month of March (1848), when its circulation was 12,000 or 13,000. On the following 15th of May this had risen to 84,000. 'La Liberté' had become a power.... I thought myself obliged to protest against the law of exile. I carried my protestation to M. Lepoitevin Saint-Alme, who refused to insert it. I severed my agreement with 'La Liberté.' "
At first "La Liberté" was moderate in tone, but with time it became more definitely anti-Napoleonic, and was probably suppressed for that reason.
The letter referred to, and which "La Liberté" refused to print, was published by "L'Assemblée Nationale," and, later, on the 1st of November, 1849, Dumas reprinted it in his own personal journal. "Le Mois."
