This document discusses the role of native Mesoamerican peoples in assisting the Spanish conquistadors during the 16th century conquest of Mexico and other parts of Mesoamerica. It notes that the Spanish forces were often outnumbered by their native allies and depended on local support for food, porters, and additional soldiers drawn from cities like Tlaxcala. Numbers of native warriors participating ranged from thousands to tens of thousands. The document also references the presence of black and mixed-race soldiers in Spanish campaigns, and how Mesoamerican warriors also suffered and participated in later conquests of other regions like Peru and the Andes.
