- The service of James A. Peden to Argentina was complex, as reflected in his multiple entries in this database. He was commissioned as Chargé d’Affaires to the Republic of Buenos Aires, but did not proceed to post in this capacity. Nominated on February 25, 1856, to be Envoy Extraordinary and Minister Plenipotentiary to the Argentine Confederation, his nomination was withdrawn before the Senate acted upon it. He did serve as Minister Resident to the Republic of Buenos Aires from January 22, 1855, to about May 1, 1857. Although Peden was not commissioned as Minister Resident to the Argentine Confederation until June 25, 1856, he had been given letters of credence dated July 1, 1854, to both Buenos Aires and the Confederation, and had presented his credentials at Parana on December 1, 1854, before proceeding to Buenos Aires. Peden resided at Buenos Aires until about May 1, 1857, when he closed the Legation at that city and moved to Parana, where the U.S. Legation to the Argentine Confederation remained until 1862.
