The war was declared when Argentina invaded the province of São Pedro and Iguaçu. Lott was elected less than one month ago, and king Carlos decided to dismiss Kubitschek and put Lott to assume his place. Paulist troops were mobilized to the province of Bandeirante, then entered into the Chaco territory, and invaded the provinces of Formosa and Chaco. Leading a group of soldiers and citizens, Juan Domingo Perón and his rebellious army mobilized citizens from Buenos Aires to Córdoba.
