"The Hundred Hour War – Did a soccer match really start a war?" investigates the 1969 conflict between El Salvador and Honduras, famously known as the "Football War." Tensions exploded during the qualifying matches for the 1970 FIFA World Cup, leading to riots in the stadiums and eventually a four-day military invasion. Historian Carlos Field explains that soccer was just the spark, not the fuel. The real causes were land reform, immigration, and trade disputes. However, the image of fan violence turning into aerial dogfights (the last in history to use piston-engine planes like the Corsair) captivated the world. This book serves as a grim reminder of how nationalism can weaponize sports. It deconstructs the myth while acknowledging that for four days in July 1969, the line between a game and a battlefield completely vanished.
