The Gran Chaco War: Fighting for Mirages in the Foothills of the Andes
The Gran Chaco is the most inhospitable part of the inhospitable Chaco Boreal, a largely uninhabited, 250,000 sq-mi region west of the Paraguay River and east of the foothills of the Andes in Paraguay, Bolivia, and Argentina. It is an arid, semi-desert, where some of the highest temperatures recorded in South America are encountered. In the west, near the mountains, the Gran Chaco is a flat, sparsely vegetated, waterless plain. Further east it is a thick, dry, almost impassable thornbrush jungle punctuated by dense stands of quebracho trees and grassy clearings. There are few people, but myriad biting, stinging insects and many tropical diseases. Prior to 1928, the region's only real value was the tannin extracted from its quebrachos and the meager grazing it provided for cattle. Such was the unlikely bone of contention in South Americas bloodiest, twentieth-century war.
The Gran Chaco belonged originally to the same Spanish colonial district (audiencia) as Bolivia. So it was, in Bolivian eyes, legally subject to the Spanish administration's successor government in La Paz. But the mountain peoples of the Bolivian Altiplano, a Quecha Indian underclass and a Spanish aristocracy, descended from Spanish conquistadores, had little real connection with the sweltering lowlands of the Gran Chaco or with the indigenous peoples who inhabited it. Bolivians did not live in the Chaco,nor did they exploit its meager resources. Bolivian businessmen looked into the possibility of a port on the Paraguay River, but otherwise did little to make use of the territory, gravely compromising their claims to the area, at least in North American and European eyes. On the other hand, the Guarani, the largely indigenous people of Paraguay, were linked to the Chaco by culture and language. Paraguayan settlers had long since brought cattle to the region and had established a tannin industry based on the quebracho. Paraguay had settled and improved the country. The government had brought industrious Mennonite communities from the United States to settle in the Chaco and had sold extensive tracts to Argentinian land developers and cattle companies. Thus, while Paraguay had claimed the Chaco when Spanish rule collapsed in 1810, its real hold rested on de facto groundsuse and occupationrather than de jure title
So matters might have rested. Bolivia might never have taken an interest in its one-time de jure territory, and Paraguay might have gone on with its quiet, unofficial settlements. But in 1884, Bolivia had lost the Pacific War and, with it her coastline, to Chile. To the nineteenth-century mind, great powers were sea powers that could carry on trade and project power over global distances. Suddenly, Bolivia had to either give up her aspirations to greatness or find some other outlet to the sea. The former course was anathema to fiercely nationalistic Bolivian politicians, newspaper editors, and student agitators. The officer corps of the defeated army likewise rejected any course that conceded the reality of defeat. Bolivians thus turned their hopes to their remaining frontier, the Chaco Boreal and its navigable border, the Paraguay River.
At first, both sides seemed content to press their claims by peaceful means. A series of international arbitrations and temporary settlements brokered by Argentina, President Hayes of the United States, and King Leopold of the Belgians kept the peace for a time. Both sides marshalled their historians and turned over their archives for supporting documentation. Meanwhile, the status quo continued.
Then, in 1928, oil was discovered in the foothills of the Andes at the western extremity of the Chaco. Bolivia suddenly took belated notice of its neglected territory and sought to assert its rights. The Gran Chaco seemed on the verge of an oil boom. Further oil fields might lie beneath the Chaco's arid plains. More importantly, Bolivian-controlled pipelines and a sovereign oil port now seemed absolutely necessary. Without them, Argentina would have a monopoly on shipping the oil and the nation's rightful profits would be syphoned off by foreign speculators. Paraguay reacted to this sudden onslaught from the north with violent indignation. The Guarani saw no reason why the late-comers from the mountains should enjoy the fruits of their labors, simply because a defunct colonial power had made a few thoughtless marks on a map. They were in no mood for territorial concessions. At the time of its independence from Spain in 1811, Paraguay had been one of the larger nations on the continent. But three neighbors, Argentina, Uruguay, and Brazil, had seized more than half its territory in the War of the Triple Alliance. The loss still rankled, and impoverished Paraguay was not prepared to let its last hope for economic development join its other lost territories.
Fighting began in 1928, when Bolivia tried to establish an outlet to the sea via the Paraguay River. Paraguayan troops wiped out a newly established Bolivian border fort. An exchange of sporadic raids and skirmishes commenced. But formal warfare did not start for four more years. The League of Nations carried on a series of desultory negotiations and arranged a truce.
When full-scale hostilities commenced in June 1932, both countries immediately faced daunting logistical difficulties. The swamps and forests, together with the lack of roads, the harsh climate, and the vast distances involved, made assembling and moving troops extremely difficult. Soldiers and animal transport were ravaged by disease, ill-fed, and chronically short of materiel. Yet the belligerents were determined to fight a proper, modern war, in so far as their means would allow.
At first, Bolivia had the advantage militarily, particularly in the air. In the course of the conflict, the Cuerpo de Aviación had about sixty combat aircraft available, including various fighters, Curtiss bomber-reconaissance biplanes, and Junkers W.34 bomber-transports. In 1930, it used the proceeds of its mines and a line of credit from Standard Oil of Bolivia to conclude a major arms deal with Vickers. Bolivia acquired a number of Vickers 6-tonne tanks (right) and Carden-Lloyd Mk. VI tankettes (machinegun carriers), 55-mm mountain artillery, Vickers machineguns, and six Vickers Type 143 Bolivian Scouts, an export fighter for which Bolivia proved the only customersurely one of the shortest total production runs on record. The Scout's supercharged, 500-hp Bristol Jupiter VIA radial engine and generous wing area gave the Scout a good high-altitude performance for its day, an important consideration in Bolivia. It spanned 33 ft 6 in, was 26 ft 3 in long, and weighed 2246 lbs maximum at takeoff. Service ceiling was 20,000 ft and maximum speed was 150 mph. Like all the fighters in the conflict, it was armed with a pair of rifle caliber machineguns, .303 Vickers in this case.

Fighters, Cuerpo de Aviación Boliviano, 1930-35: Curtiss Hawk II (top); Vickers Type 143 Bolivian Scout (bottom)
Four Curtiss P-1 Hawks were acquired in 1927 and nine Hawk IIs in 1932-33. The Hawk II was the principle Bolivian fighter. It was essentially a land-based version of the US Navys BFC Goshawk. A 600-hp Wright R-1820 gave the Hawk II a 202-mph top speed and a 25,000-ft service ceiling. Nine Curtiss Falcon two-seat reconaissance bombersradial-engined variants of the US Army O-1/A-3were added at the same time. The ground troops were meanwhile provided with organic air defense in the form of excellent SEMAG-Becker 20-mm AA guns, two of which were supplied to a division (Bolivian divisions were actually of regiment or batalion size).

While Bolivia began the war with new, Vickers- and Curtiss-built equipment, impoverished Paraguays armed forces were caught between procurement cycles and desperately short of cash. From 1927-1929, the country had re-equipped its air force with a number of French-made Potez 25A.2 reconaissance bombers and seven Wibault 73C.1 fighter monoplanes (numbered 1-7). The Potez 25 was a widely exported two-seat biplane developed primarily as what would later be called a COIN airplane. It was designed for use against the fractious, independence-minded natives of Frances colonies. It looked very much like a WW1 type. While excellent for its intended purpose, it was at a definite disadvantage when facing aerial opposition. It spanned 46 ft 4.75 in, was 29 ft 10.25 in long, and weighed 4317 lbs (t/o). It could reach 137 mph and 23,600 ft. Range was 410 miles and bombload was 440 lbs. The Wibault was a rarity for its time, an all-metal parasol monoplane covered with Wibaults own system of corrugated metal skinning. It was about 25 ft long, spanned 35 ft 11 in, and weighed 3351 lbs. Performance closely approximated that of the Potez.

Unfortunately, the aircraft were already obsolescent in 1932. Worse still, Paraguay had tried to economize by standardizing on one engine for both fighters and bombers. Unfortunately, the engine Paraguay chose was the 450-hp Lorraine-Dietrich 12Eb. This was a water-cooled, W-12 with three banks of four cylinders each. It was heavy and old fashioned, and its cooling system had been marginal even in northern Europe. In the sweltering Gran Chaco, it was a disaster. So much had been spent for the airplanes, however, that nothing could be spared for replacements. What little finance was available had to be spent on other, more urgently needed armaments. Shortly after the start of operations, Paraguayan mechanics found themselves frantically cannibalizing aircraft to keep a minimum number of flying. Many were lost to forced landings and in-flight fires. Soon, serviceability was so bad that the Wibaults had to be grounded so that the remaining engines could be reserved for the more urgently required Potez.
The army was in somewhat better shape. During the final months prior to the outbreak of war, Paraguayan diplomats secured a secret loan from Argentina. Unlike Bolivia, Paraguay had almost no standing army and no peace-time budget for mobilization stockpiles. While their troops fought the first skirmishes of the war armed with machetes and one castoff Argentine Mauser rifle for every 3-7 men, a civilian purchasing commission frantically shopped the arms bazaars of Europe for bargain equipment. Ironically, the inexperience of the men selected for the task and the crippling, national lack of funds now proved fortuitous. While Bolivia's professionals spent lavishly on "serious" weapons, like heavy Schneider howitzers, water-cooled heavy machineguns, tanks, and the all but useless little Vickers mountain guns, the Paraguayan amateurs bought poor man's artillerylight, cheap, Stokes-Brandt mortars, three of which could be had for the price of one field gunand Madsen light machineguns (right). Cartridges and artillery shells could be had clandestinely, free of charge, from the Argentine army, and grenades were in production in Paraguay itself. In the heat, dense brush, and mud of the Chaco, lightness, mobility, and a high trajectory were the dominant requirements. Mortars, grenades, and light automatic weapons so dominated the battlefields that Bolivia was forced to return to Vickers for large quantities of both. Later in the war, when Paraguay's funds were exhausted, she relied almost entirely on capturing this fresh Bolivian materiel for her own needs.
Mercenaries were much in evidence throughout the conflict. The chief of the Bolivian general staff and, for a time, de facto dictator of the nation, was a German veteran of World War 1's Eastern Front, General Hans Kundt. Chilean mercenaries and a Czech contract military mission advised Bolivian forces in the field. Paraguay had the services of two White Russian emigrés, General Belaieff, formerly of Wrangel's staff, and Gen. Ern. Another Russian, Vladimir Porfenenko, and one Walter Gwynn flew fighters for Paraguay, the latter being killed. Late in the war, a large-scale Italian mission arrived to train and equip Paraguay's exhausted forces prior to their final victory.
Paraguay, however, relied for the most part on a series of brilliant native officers for her tactical and strategic planning, while Bolivia leaned heavily on the foreigners. Many of Paraguay's unit commanders had gained combat experience as volunteers with the French army in World War 1. They were quick to note the mistakes of their supposedly more advanced, more civilized European counterparts and made use of the experience gained in the conflict that awaited them in their homeland. Paraguay's army commander, Colonel later General later Marshal José Félix Estigarribia, epitomized the brilliance and professionalism of this largely amateur army. He was easily the greatest soldier of the war. He capitalized on the Guarani's knowledge of the forest and on the independence born of egalitarian Paraguayan life. He husbanded his meager resources, avoiding the suicidal assaults on entrenched positions that characterized the fighting on Europe's Western Front. But he also mounted audacious attacks when conditions were favorable and frequently encircled and destroyed Bolivian forces that far outnumbered his own. Unlike his Bolivian counterparts, he was on close terms with the civilian government and the elected president, Eusebio Ayala, throughout the war and recognized his duty to bow before civilian wishes.
