Teniente-Coronel George Thompson was an English engineer, and was in charge of the Paraguayan military engineering in the Paraguayan War. He was the author of an important source on its history. Because of his efforts and the valour of the ordinary Paraguayans, the Allies found it much harder to defeat Paraguay than they had imagined.
Early life
Thompson was born at Greenwich on 26 March 1839. In 1849 he was sent to a school near Stuttgart, which he left in 1852, continuing his studies near London until 1854. From 1855 to 1857 he served an apprenticeship at the government works at Malta, and was put on the engineering staff of the gasworks in that island. He returned to England in 1857, and soon afterwards was engaged for one year as a draughtsman at a locomotive works. That was the total sum of his engineering experience when he left for South America in 1858, aged 19.
Paraguay
In the middle of the nineteenth century the government of Carlos Antonio López determined to open up Paraguay to modern technology, hiring for that purpose a considerable number of technicians, mainly British. In September 1858 Thompson joined the staff of the Asunción and Villa Rica railway in Paraguay, working under the British engineers George Paddison, Burrell and Valpy. Although a young man, he was soon considered to be one of the bestGuaraní scholars amongst the English, besides speaking fluently five or six other languages.
The Paraguayan War
The war between Paraguay and the allied forces of Brazil and the Argentine and Uruguayan Republics having broken out, Thompson, in 1865, offered his services as a military engineer to the Paraguayan President, Francisco Solano López, and this offer being accepted, he joined the army in June of that year, and took a prominent part in the war until the end of 1868. At the war's outbreak Thompson was a railway engineer and he had no military experience at all. Furthermore, throughout the war, Paraguay's nominal chief military engineer, Hungarian colonel Wisner de Morgenstern was seriously ill, and so the work fell on Thompson's shoulders. Thus it was that an untried 26-year-old man became the de facto chief military engineer of the Paraguayan army: Improvising, he used the material and human resources of the country and made earthworks, fortifications and artillery emplacements. His most notable works were the fortifications of Angostura and the trenches – constructed, surreptitiously, overnight, in daring proximity to the Allies' positions – of the Boquerón del Sauce and Curupaity; Angostura held at bay the Allies’ fleet for several weeks, and the Curupaity trenches led to the Allies’ worst defeat of the war. Thompson was promoted to the rank of lieutenant- colonel in the Paraguayan army, and received from President Lopez the decoration of ‘’Caballero del órden del mérito’’. Although obliged to capitulate at Angostura, the allies allowed him the honours of war, as he refused to surrender at discretion.
After the war
A few months were passed in England in 1869, during which he wrote The War in Paraguay: With a Historical Sketch of the Country and Its People and Notes Upon the Military Engineering of the War. Since Thompson had been the foreigner with best access to President López – from whom he took his orders in Guaraní – and privy to many military matters, the book is an important source on the history of the war. Thompson then returned to South America and married a Paraguayan woman by whom he had three children. After some topographical work inCórdoba, Argentina In 1870 he returned to Paraguay and became the Engineer and Manager of the Asunción – Villa Rica railway. He died in Asunción in March 1876, aged 37.
