Ernesto "Che" Guevara (June 14, 1928 – October 9, 1967), was an Argentine Marxist revolutionary, politician, author, intellectual, physician, military theorist, and guerrilla leader.
 His life, legacy, and ideas have attracted a great deal of interest from historians, artists, film makers, musicians, and biographers.
 In reference to the abundance of material, Nobel Prize–winning author Gabriel García Márquez has declared that "it would take a thousand years and a million pages to write Che's biography."
The First Battle of Nanawa was a battle fought from 20 to 26 January 1933 between the Bolivian and Paraguayan armies during the Chaco War.
 Nanawa (Enxet for "carob tree forest"), established by the Paraguayans in 1928, was considered the strongest Paraguayan outpost after it was heavily fortified by the end of 1932 under directives of Ivan Belaieff and Nicolas Ern, two White Russian veterans who joined the Paraguayan army in the 1920s.
 Zig-zag trenches, barbed wire and machine gun nests were built by the garrison around a horseshoe-shaped defence.
 Nanawa's commander, Col. Luis Irrazábal, summoned under his command four regiments and several minor units which made up the Paraguayan fifth division.
 The commander-in-chief of the Bolivian army, German World War I veteran Hans Kundt, commanded the Bolivian assault personally in place.
 The Bolivian army launched three attacks that stalled after seizing some parts of the stronghold.
 After this failure, the Bolivian troops attempted to dig a trench around the Nanawa complex to isolate it but were met by Paraguayan reinforcements.
 Heavy rains forced the Bolivians to abandon what they had captured of the complex and the Paraguayans soon recovered these positions.
Mario Terán (born c. 1940) is the Bolivian Army sergeant who was chosen to carry out the execution of Marxist revolutionary Che Guevara as a young man on October 9, 1967.
Ernesto "Che" Guevara (] June 14, 1928 – October 9, 1967) was an Argentine Marxist revolutionary, physician, author, guerrilla leader, diplomat and military theorist.
 A major figure of the Cuban Revolution, his stylized visage has become a ubiquitous countercultural symbol of rebellion and global insignia in popular culture.
Alberto Díaz Gutiérrez, better known as Alberto Korda or simply Korda (September 14, 1928 – May 25, 2001), was a Cuban photographer, remembered for his famous image "Guerrillero Heroico" of Argentine Marxist revolutionary Che Guevara.
Appearances of Argentine Marxist revolutionary Che Guevara (1928–1967) in popular culture are common throughout the world.
 Although during his lifetime he was a highly politicized and controversial figure, in death his stylized image has been transformed into a worldwide emblem for an array of causes, representing a complex mesh of sometimes conflicting narratives.
 Che Guevara's image is viewed as everything from an inspirational icon of revolution, to a retro and vintage logo.
 Most commonly he is represented by a facial caricature originally by Irish artist Jim Fitzpatrick and based on Alberto Korda's famous 1960 photograph titled "Guerrillero Heroico".
 The evocative simulacra abbreviation of the photographic portrait allowed for easy reproduction and instant recognizability across various uses.
 For many around the world, Che has become a generic symbol of the underdog, the idealist, the iconoclast, or the martyr.
 He has become, as author Michael Casey notes in "Che's Afterlife: The Legacy of an Image", "the quintessential postmodern icon signifying anything to anyone and everything to everyone."
Che is a two-part 2008 biopic about Argentine Marxist revolutionary Ernesto "Che" Guevara, directed by Steven Soderbergh and starring Benicio del Toro.
 Rather than follow a standard chronological order, the films offer an oblique series of interspersed moments along the overall timeline.
 "Part One" is entitled "The Argentine" and focuses on the Cuban Revolution from the landing of Fidel Castro, Guevara, and other revolutionaries in Cuba to their successful toppling of Fulgencio Batista's dictatorship two years later.
 "Part Two" is entitled "Guerrilla" and focuses on Guevara's attempt to bring revolution to Bolivia and his demise.
 Both parts are shot in a cinéma vérité style, but each has different approaches to linear narrative, camerawork and the visual look.
Haydée Tamara Bunke Bider (November 19, 1937 – August 31, 1967), better known as Tania or Tania the Guerrilla, was an Argentine-born East German communist revolutionary and spy who played a prominent role in the Cuban government after the Cuban Revolution and in various Latin American revolutionary movements.
 She was the only woman to fight alongside Marxist guerrillas under Che Guevara during the Bolivian Insurgency (1966–1967) where she was killed in an ambush by CIA-assisted Bolivian Army Rangers.
The legacy of Argentine Marxist revolutionary Che Guevara (June 14, 1928 – October 9, 1967) is constantly evolving in the collective imagination.
 As a ubiquitous symbol of counterculture worldwide, Guevara is one of the most recognizable and influential revolutionary figures of the twentieth century.
 However, during his life, and even more since his death, Che has elicited controversy and wildly divergent opinions as to who he was and what he represented.
 Mostly revered and occasionally reviled, he is passionately characterized along the entire continuum as everything from a heroic defender of the poor, to a cold-hearted executioner.
 Admired, sanctified, romanticized and derided, his crystallized status as either a brilliant intellectual or a violent ideologue is usually dependent on where one falls along the left and right of the political spectrum.
 The debate around his legacy is further complicated by the fact that Guevara exists simultaneously as several different entities, both literal man and global emblem, leading to disputes between what people contend he did and what he now represents.
The Battle of Cañada Strongest was a battle fought from May 10–25, 1934, between the Bolivian and Paraguayan armies during the Chaco War.
 The engagement is considered the greatest victory of the Bolivian army during the war, and actually took place some 60 km southwest of Cañada Strongest, near a dried riverbed called Cañada Esperanza.
 The battle was a Paraguayan attempt to outflank and eventually conquer Fort Ballivian, a large stronghold that was the keystone of Bolivian defenses along the border with Argentina.
 Paraguayans begun to open a new trail in the dry subtropical forests of the Chaco but were discovered by Bolivian aerial reconnaissance.
 The Paraguayans troops, unaware of having been discovered, were encircled by Bolivian forces who had sneaked up on the path and were waiting for a substantial number of Paraguayan troops to enter the pathway before they ambushed them.
 A 250-man Paraguayan detachment sent in to monitor the Bolivian movements was also surrounded and eventually captured on May 25 along Lóbrego Path, a route between the first Paraguayan lines and Cañada Esperanza.
 The Bolivian army took 1,500 prisoners and a good amount of weaponry, trucks and supplies, while almost 400 Paraguayan soldiers were killed.
 A whole Paraguayan division, however, managed to slip away, along with some scattered units.
