After the disbandment of the forces of José Egídio Gordilho, the Viscount of Camamu, in the battle of Azenha Bridge on the night of 19 to 20 of September 1835, the rebels decided to capture Porto Alegre.

On the morning of the 20th, they penetrated the perimeter of the city, without resistance, with support of the National Guard and reinforcements of around 300 men from captain Manuel Antunes de Porciúncula (Bento Gonçalves' brother-in-law).

[1] Once the government was deposed, the City Council, extraordinarily convened by Bento Gonçalves on 21 September, inaugurated Marciano José Pereira Ribeiro, a physician from Minas Gerais[2] and fourth in the general order of precedence of vice-presidents of the province, as the new provincial president.

[1] In São Gabriel, there was resistance until 4 October 1835, when the 3rd Regiment of Line Cavalry joined the rebels, led by lieutenant colonel and later general João Antônio da Silveira.

[1] The strongest reaction took place in Herval, from lieutenant colonel João da Silva Tavares, who started to dominate the area between Jaguarão and Pelotas with a group of men from his family.
