The Imperial Brazilian Army was, at the beginning of the Paraguayan War, very small and dispersed throughout all of Brazil. Service in the army was seen as a punishment, given the harsh conditions the soldiers found themselves in. The army also lacked prestige, its ranks were filled with men who were seen as undesirables by the society of the time. The
Marquis of Caxias wrote to the Minister of War, the
Marquis of Paranaguá, in reference to the state of the army prior to the war, that: Deprived of war resources, without a sufficiently numerous and trained army and unable to adequately retaliate for the Paraguayan offense received after the invasion of Mato Grosso in December 1864 (before formal declaration of war, which happened on 13 December 1864), emperor
Pedro II issued the Decree No. 3,371 on 7 January 1865; This decree, appealing to the patriotic feelings of the Brazilian people, created military corps for the service of war, with the denomination of
Voluntários da Pátria. The emperor soon left for the city of
Uruguaiana, which was occupied by Paraguayan forces and
besieged by the allied army, on September 11. He disembarked in
Rio Grande do Sul and continued from there by land. The journey was carried out by horse and cart, and at night the emperor slept in a field tent. In Uruguaiana, he presented himself at the army camp as the country's first volunteer, using this political strategy to serve as an example both to the military stationed there and to the rest of Brazil. ==Recruitment==
