Convicts transported to Austraila
Some soldiers committed crimes so they would be transported to Australia, according to Emma Roberts who was in India 1828-1832. She wrote: "A few [soldiers], driven to despair by the melancholy prospect of interminable exile, unable to await the slow approach of their recall, and allured by the flowery descriptions of Australia, plunge into crime for the purpose of exchanging honourable servitude in India for a felon's lot in a climate resembling that of England. It is no very unusual circumstance for a soldier to attempt the life of his officer or his comrade, in the hope of being transported to a country possessing so many features akin to the land of his birth; and even the punishment of death is to some less terrible than the prospect of eternal banishment from "the home they left with little pain.""
