October 1811: All the eastern villages of the future state of Uruguay were occupied by Portuguese troops, and on October 14, the Portuguese headquarters was placed in Maldonado.
September 1812: The government of Buenos Aires ordered Artigas to return to his camp on the Ayuí stream after the signing, on March 26, of the Rademaker-Herrera Treaty, which determined the return of Portuguese troops to Brazil. Once again, Souza did not recognize the agreement, but after a series of clashes he received the order to withdraw from the Banda Oriental by King John VI, an order which he finally carried out on June 13. A few days later, the commander of the Portuguese-occupied portion of Misiones, Francisco das Chagas Santos, attempted to attack La Cruz, which was defended by Corrientes' forces, but withdrew after Galván informed him that hostilities had ceased. On September 13, the armistice was ratified, despite Vigodet's attempts to prevent its application. However, the Portuguese did not return to the pre-invasion borders, maintaining control of the current municipalities of Uruguaiana, Quaraí, Santana do Livramento and Alegrete, and part of those of Rosário do Sul, Dom Pedrito and Bagé.
