The challenge, should you wish to accept it, is to have the plan created by the leaders of the "Revolução Pernambucana" of 1817 succeed, but with the addendum of Napoleon staying in South America, ruling Brazil.
At the beginning of 1817, the merchant Antônio Gonçalves Cruz, the "Cabugá", was sent by the revolutionaries from Pernambuco to Philadelphia, former capital of the USA. He had $800,000 dollars in his luggage, a staggering amount for the time. Cabugá had three missions. The first was to buy weapons to combat the troops of King Dom João VI (1767-1826). The second is to convince the US government to support the creation of an independent republic in the Brazilian Northeast. The third and most spectacular of all aims was to recruit some former French revolutionaries exiled in American territory and with their help, to free Napoleon from St. Helen. By said plan, Napoleon be retrieved in the dead of night and transported to Recife, where he would command the Pernambuco revolution and then , supposedly, return to Paris and resume the throne as emperor of France.
