1537 CE
The surviving Querandí ally with one another to besiege and force the abandonment of the recently founded city.
With the Spaniards abandoning their livestock, they adopt horse-riding and pursue wild cattle and other game, thus generating a new equestrian lifestyle.
They continue being nomads, and they can more easily make contact with other native peoples and successfully made war on the Spanish.
The colonists' settlement is surrounded by a hastily made one meter (three foot)-thick adobe wall made of mud.
Every time it rains, the wall partially dissolves.
Along with this occasionally deteriorating wall, the colonists have to deal with famine.
Food eventually becomes scarce, and the residents have to resort to eating rats, mice, snakes, lizards, rawhide boots, and even the bodies of those who die.
Mendoza, ill and beset by increasingly hostile locals, departs for Spain but dies at sea on June 23, 1537.
