“Conquest”  

From 1527 to 1529, Jorge de Alvarado and his Nahua allies were able to conquer most of what is now Guatemala. The success of the conquest is due in large part to the participation of the indigenous conquistadores from central Mexico who fought alongside the Spaniards. The indigenous warriors were familiar with the roads, local customs of warfare, and the languages. In addition, they provided the manpower.

There is so much detail in this.  The online exhibit, Capturing Warfare: Enemies and Allies in the Pre-Columbian World has many such detailed artworks with descriptions.
