According to the most common story, Corporal Ruiz, born a slave (perhaps in Africa), served in the Regiment of the River Plate and died while defending the colors (white and light blue) of the revolutionary flag (later the Argentine flag) against traitors during a revolt at the fort of El Callao, Peru) on February 6, 1824.

[3] On the night of 4 to 5 February 1824, the garrison of El Callao, which was composed by the remains of Army of the Andes and an artillery company from Chile, started a mutiny, which was joined by two squadrons of the Mounted Grenadiers Regiment.

These soldiers revolted because they were owed five months' pay, to what was said the day before had been paid the salaries of the officers, the desire to return home, either Buenos Aires or Chile, and the disgust of having to sail north to swell the army of Bolivar.

Seeing the prevailing indiscipline, the mulatto Moyano, Olive accepts the suggestion of consulting Royalist Colonel Jose María Casariego, who was taken captive and lodged there.

The night of 6 February the black Falucho was a sentry in the tower of King Philip, which belonged to the Regiment of the River Plate.

Falucho answered sadly getting the gun he had dropped "I can not do honor to the flag against which I will fight forever," then the mutineers shout at him: "Revolution!"

A black soldier from the regiment of the Rio de la Plata, born in Buenos Aires named Antonio Ruiz (whose surname Falucho), who struggled to do justice, was shot at the foot of the Spanish flag.

In 1899, Manuel J. Mantilla wrote in his book Los Negros Argentinos stating that there were two Faluchos, Ruiz, whose fate was recalled by Martinez and Diaz-Espinosa, and another who lived in Lima in 1830, according to Miller's letter to San Martin del 20 August that year.

The only thing we know for sure is that a black soldier died heroically in El Callao while refusing to honor the Spanish royal flag.
