He soon realized that he did not have enough strength to defend the city, and on 23 August he ordered a massive retreat of all the civilian population to the interior of Tucumán Province in what was later known as the Éxodo Jujeño. Civilians and military men retreated, destroying anything that could be of value to the royalists. When the Spaniards entered the city, they found it empty:
