Baltazar García Ros

Baltazar García Ros (Valtierra, Spain, ca. 1670 - Buenos Aires, Río de la Plata, September 18, 1740) was a Navarrese-Spanish soldier and administrator. He was maestre de campo and interim governor of the Governorate of Paraguay from 1706 to 1707 and governor of the Governorate of the Río de la Plata from 1715 to 1717. During his career, he campaigned against the indigenous Charrua, Yaro, and Bohán people; the Portuguese; and the comunero rebels of Paraguay.

Biography Baltazar García Ros was born around 1670 in Valtierra in Navarre. He enlisted in the army and participated in the Italian Wars. He later left for the Viceroyalty of Peru in the Spanish Empire and arrived in Buenos Aires in 1701, where he was conferred the position of sargento mayor. García Ros was a brave soldier who fought successful campaigns against the Aboriginal Charrua, Yaro, and Bohanes during this time. In 1724, he was sent to end the governorship of José de Antequera y Castro of Paraguay with military force; Antequera was an official of the Real Audiencia of Charcas who had deposed the former governor and replaced him, an act which the Viceroy considered illegal. Ros's force, composed largely of mission Indians, was soundly defeated by a surprise attack from Antequera's Paraguayan militia. García Ros was forced back in defeat. Antequera's victory was short-lived, though; Governor Zabala personally organized a larger force the next year, and Antequera fled Zabala's oncoming troops in 1725, ending the first phrase of what would later be known as the Revolt of the Comuneros of Paraguay.

García Ros died in Buenos Aires on September 18, 1740.
