Jan 1812 Succeeded Purveyor Joseph Gunson to the Purveyor's Department in the Peninsula. He was chosen to put a stop to the fraud perpetuated by his predecessor. However, by the time he left in October 1813, he had not only carried on embezzling, but had adjusted the regulations so as to make it easier for himself and his subordinates. Vouchers were submitted for items of expenditure in far excess of what had been issued to the patients with the purveyor pocketing the difference.2
