[1] Maurity joined the Naval Academy in 1860 after graduating from Pedro II School.

He distinguished himself in the episode because, ignoring orders, he advanced alone,[2] during at least three attempts, under intense artillery fire from the fortress and succeeding.

[3] Regarding Maurity's success at the time of the passage of Humaitá, the Viscount of Taunay later recorded, in his return to the theater of war as secretary of the Count of Eu, after withdrawing from Laguna: "my objective was glory, glory in every sense, military, literary!...

I thought, then, that I could climb, climb very high, becoming known throughout Brazil, thus a kind of Maurity, whose name was so acclaimed since the famous feat of passing through the batteries of Humaitá, on 18 January 1868” and that “It was, in fact, difficult to enjoy more popularity than this naval officer.

[...] At that time, however, there was only talk of Maurity, and everywhere cities on the coast and inland acclaimed and gave him brilliant and continuous parties".
