In November 1859, Thornton ordered the Royal Navy to attack the Paraguyan war steamer Tacuari, which future president Francisco Solano López was  on, to pressure his father President Carlos López to release a British citizen from prison. This was one of several incidents that damaged Paraguayan relations with Britain. Thornton would later apologise for the action to repair relations, and promised Britain had no intention of interfering with Paraguayan jurisdiction. His actions were used in a House of Commons debate on a potential war with Brazil, with William "Seymour" Vesey-FitzGerald calling him "a gentleman who knows how to conciliate... that it is not his duty to "read lessons" to foreign Governments" as an attack on Brazilian consul William Dougal Christie, while  opposing MP Layard pointed to Thornton as proof that Britain did not take a "high hand" with Latin American nations.

Box, Argentine foreign minister Rufino de Elizalde informed Thornton the Argentine government had no wish  to annex Paraguay, but hoped that in the long term Paraguay might voluntarily join the Argentine Confederation (as was contemplated by Article 13 of the Argentine Constitution). He also informed Thornton that the Argentine Congress feared the provisions in the Treaty might prevent such an occurrence. After the war concluded, Thornton was withdrawn from his position, having concluded several agreements during his tenure. Minister to the United States.

For his services Thornton was invested Knight Grand Cross of the Order of the Bath in 1883.
