However, unlike the case of Rivadavia, San Martín's support to the Latin American integration contradicted the strong centralism of the government party.

[6] However, in the specific case of San Martín this scenario could seem contradictory, as he had left America as a child and served for the Spanish army for 22 years.

As a result, his military career in Spain is summarized in six pages (the whole book has more than six hundred), giving very little detail about him before his arrival to Buenos Aires.

[7] As for the reason for his departure from the Spanish army to join the South American ones, the book describes that "he decided to return to his distant nation, which he had always loved as a true mother, to offer her his sword and devote her his life".

Historian Norberto Galasso considers that his late life was full of events that would contradict the portrait of San Martín by Mitre: his rivalry with Rivadavia, his rejection of the execution of Manuel Dorrego and his conflict with Juan Lavalle, his support to Juan Manuel de Rosas (including the gift of his sword), and his repudiation to the French and Anglo-French blockades and the role of the unitarians in them.
