From 1864 to 1870, Paraguay fought against Argentina, the Empire of Brazil, and Uruguay in a war that took place in South America.[1][2] This conflict ranks as the most lethal war between states in Latin America's past; Paraguay experienced extremely high losses, though exact figures remain contested.[2]

Life and work
Historian Pelham Horton Box noted that Spain bequeathed frontier disputes with Portuguese Brazil to the new nations.[3] The war's origins are attributed to multiple factors, including Paraguayan president Francisco Solano López's policies and the Uruguayan War.[4] Paraguay began the conflict with over 60,000 trained men, 400 cannons, and a naval squadron of 23 steamboats.[5] The Paraguayan army was poorly equipped, with most infantry using inaccurate smooth-bore muskets and poor artillery.[6]

Brazil, Argentina, and Uruguay initially had smaller forces, but Brazil's navy comprised 45 ships with 239 cannons and about 4,000 crew.[5] Paraguay launched invasions of Mato Grosso in December 1864 and of Corrientes and Rio Grande do Sul in early 1865.[7][8] Boundary disagreements that arose from colonial-era uncertainties caused friction between the newly independent nations in the region.[9]



What the cited sources add
An Osprey Publishing book from 2015 details that the Paraguayan peacetime army had eight infantry battalions of 800 men each, mustering only 4,084 infantrymen.[10][11] The Osprey book also states that Paraguay relied on a militia of all able-bodied men, which increasingly included younger and older men as the war continued.[10][11]
