He was deported back to Buenos Aires by Uruguayan President Fructuoso Rivera, at the request of his minister Manuel Oribe.

In Buenos Aires, he joined the federalist party and wrote a poem comparing Rosas with an ear of corn ("Mazorca") because of his blond hair.

In 1841 Rosas survived a terrorist attack made with a gift that secretly contained a complex mechanism of guns, which would fire in all directions when opened.

In 1843 the French firm Lafone & Co. hired Indarte to write an account of deaths caused in Argentina by the government of Rosas; the resulting document was known as the Blood tables.

He tried to add to the list another 22.560 names, the number of deaths caused by military conflicts in Argentina from 1829 to that date, but the French refused to pay for them.
