"Governor Thomas Ford later wrote of him:
This Bennett was probably the greatest scamp in the western country. I have made particular enquiries concerning him, and have traced him in several places in which he lived before he joined the Mormons, in Ohio, Indiana, and Illinois, and he was everywhere accounted the same debauched, unprincipled, profligate character. He was a man of some little talent, and in 1840-1841 had the confidence of the Mormons, and particularly that of their leaders. (Thomas Ford, A History of Illinois (Chicago, 1854) p. 263) (Flaunders 1966, 49-50)
The publication of John C. Bennett's book provided considerable fuel to an increasingly violent opposition to the Latter-day Saints. By making a correlation between increased persecution and publication dates, the following books seem to have exacerbated hostilities: (Arrington & Bitton 1979, 59)
