American pirate, frontiersman, fur trapper, fur trader, hunter, and explorer Hugh Glass (c. 1780 - 1833) once made his way crawling and stumbling 200 miles to Fort Kiowa, in South Dakota, after being abandoned without supplies or weapons by fellow explorers and fur traders during General Ashley's expedition of 1823. 'The Revenant - Some Incidents in the Life of Hugh Glass, a Hunter of the Missouri River' by Philip St. George Cooke is the key historical document supporting the Glass story. It is backed up by two other eye-witness accounts included here - 'Hugh Glass and the Grizzly Bear' by Rufus B. Sage (From 'Rocky Mountain life; or, Startling scenes and perilous adventures in the far West, during an expedition of three years' by Rufus B. Sage, published in 1857) and 'Glass and the Bear' by George Ruxton (From 'Adventures in Mexico and the Rocky Mountains by George Ruxton,' published in 1847).
