author
A 19th-century sea captain turned his ordeal into a gripping firsthand survival narrative after being taken prisoner during a violent uprising in Patagonia. His book offers a vivid eyewitness account of danger, captivity, and escape at sea's far edge.

by captain of the bark Florida Charles H. Brown
Published in 1854, The Sufferings and Escape of Capt. Chas. H. Brown From an Awful Imprisonment by Chilian Convicts presents Charles H. Brown as the captain of the bark Florida and the central witness to the events he describes. The book was later released by Project Gutenberg from the original 19th-century text.
Brown is known through this memoir-like account rather than through a large surviving public biography. In it, he recounts his imprisonment in South America and escape from the aftermath of a deadly convict revolt, writing in the direct, urgent style of someone determined to preserve what he saw.
Because reliable biographical details beyond the book itself are scarce in the sources I found, it is safest to remember him as a working ship captain whose name endures through one dramatic maritime narrative from the 1850s.
