[2][1][3] This was the first military expedition to the interior and left Buenos Aires on 20 June 1810 under the command of Bernardo Joaquín de Anzoátegui [es] captain of the Volante Artillery Battalion's 6th Company.

[2][1] Prior to the Battle of Tucumán, she sought permission from General Manuel Belgrano to tend the troops who had fallen in the front lines.

[2] Poor health and age limited her ability to provide for herself, and del Valle began begging for food at convents in the city.

[1][7] General Juan José Viamonte discovered her in the streets in a deplorable condition and petitioned the legislature on her behalf to provide her with a pension.

[9] She first appeared in a history book in Argentina in the early 1930s, when Carlos Ibarguren published her story[2] and in 1944 Buenos Aires named a street in her honour.

[9] However, she was largely forgotten until the beginning of the 21st century, when Afro-Argentines, activists and scholars began to include the history of people who had been left out of the historiography of the country because of deliberate discrimination based on gender and race.

As an afro descendant woman, she faced all the prejudices of her time... Because of her bravery, (del Valle) was appointed captain by Manuel Belgrano... in her honour, Law 26,582 set 8 November as the Day of African-Argentine people".

The monument included a statue in del Valle's image sculpted by Alexis Minkiewicz, in collaboration with Gisela Kraisman and Louis Yupanki.

On the 1 September 2023, the statue of María Remedios del Valle was burned to the ground, in an act of vandalism condemned by the Ministry of Culture.
