In 1922, "São Paulo" and "Minas Geraes" helped to put down the first of the Tenente revolts. Soldiers seized Fort Copacabana in Rio de Janeiro on 5 July, but no other men joined them. As a result, some men deserted the rebels, and by the next morning only 200 people remained in the fort. "São Paulo" bombarded the fort, firing five salvos and obtained at least two hits; the fort surrendered half an hour later. The Brazilian Navy's official history reports that one of the hits opened a hole ten meters deep.
