Translated from the original French and annotated with figures, historical maps and commentary from the translators, this work is Jean-Charles Houzeau's account of his escape from Texas during the American Civil War. Houzeau was a Belgian astronomer who worked a couple of years as assistant astronomer at the Brussels Observatory, but eventually moved to the United States. He was living as a frontierman in Texas when the Civil War broke out, and because he took an abolitionist stance and helped slaves escape, he was forced to flee to Mexico, from where he sailed to New Orleans on board of a US military vessel. Originally titled La terreur blanche au Texas et mon 'evasion, Houzeau captured the details of his escape in 1862.The editors, an astronomer and a French language teacher, have added supplementary material to give the readers more depth and historical context to the story.
