 According to allegations in a post-war Congressional investigation, Draper, who had been bankrupted by business reverses during the Panic of 1857, did not provide accurate reports on the types and amounts of cotton he sold, enabling him to divert some of the proceeds to his personal use.As a result, he was supposedly able to pay off his debts and leave a sizable estate at his death.Draper died in Whitestone, Queens County, New York on November 6, 1866.
