Escravidão ou morte

"Cartorial evidence from Rio de Janeiro suggests that traditional sources have underestimated the number of slaves recruited into the army for the Paraguayan War. Voluntários da pátria were less often volunteers then either ex-slaves forcibly recruited or slaves sold at a profit by private owners to the state or furnished as substitutes. Spotty evidence from other provinces tends to confirm this"--Handbook of Latin American Studies, v. 58.
