Ernesto "Che" Guevara, captured the previous day by Bolivian Rangers, was executed without trial on orders from the Bolivian government at the schoolhouse in La Higuera, Bolivia. His death, carried out by Sergeant Mario Terán, ended the career of the twentieth century's most iconic revolutionary guerrilla fighter. The CIA, which had trained the Bolivian Rangers and deployed agents to track Guevara, played a crucial advisory role in the operation.
Norse explorer Leif Erikson and a crew of 35 Vikings reached the North American mainland at a place he called Vinland, believed to be L'Anse aux Meadows in Newfoundland. The Norse established a settlement and conducted several voyages of exploration before withdrawing, making Leif's expedition the first documented European arrival in the Americas nearly 500 years before Columbus.
Spanish missionaries and a small military escort established the Mission San Francisco de Asís (Mission Dolores), securing Spain's claim to the San Francisco Bay area. The military presidio established alongside the mission would become one of the most strategically important military installations on the Pacific coast, evolving into the Presidio of San Francisco, a U.S. Army post for 148 years that served as headquarters for the defense of the Pacific coast.
Citizens and militia officers of Guayaquil, Ecuador's largest port, overthrew the Spanish colonial garrison and declared independence, initiating the military campaign that would liberate what is now Ecuador from Spanish rule. The revolt was coordinated by creole militia officers including Jose de Villamil and provided the southern base from which Simon Bolivar and Antonio Jose de Sucre would launch the final campaign against Spanish forces in the Andes.
Union cavalry under Generals George Custer and Wesley Merritt routed Confederate cavalry under Generals Thomas Rosser and Lunsford Lomax at Tom's Brook in the Shenandoah Valley, Virginia. The pursuit lasted over 20 miles, earning it the nickname "The Woodstock Races." The victory secured Sheridan's destruction of the Valley's agricultural resources and eliminated the Confederate cavalry threat in the Shenandoah.
German, Austro-Hungarian, and Bulgarian forces captured Belgrade, the Serbian capital, in a massive three-front offensive that overwhelmed the Serbian army. Serbia had successfully repelled two Austrian invasions in 1914, but the combined weight of three empires proved too much. The Serbian army conducted a legendary winter retreat through the Albanian mountains to the Adriatic coast, losing over 100,000 men to combat, exposure, and disease.
The U.S. War Department reorganized the Army Air Forces, giving its commanding general authority equivalent to the Army's Ground and Service Forces commanders. The reorganization, pushed by General Henry "Hap" Arnold, was a critical step toward the establishment of an independent U.S. Air Force in 1947.
The Naval Battle of Vella Lavella in the central Solomons concluded with American destroyers engaging a Japanese destroyer force attempting to evacuate 600 troops from the island. USS Chevalier was sunk and USS Selfridge badly damaged; the Japanese lost destroyer Yugumo but successfully evacuated their garrison, a small tactical victory within the larger Allied leapfrog strategy.
A massive landslide into the Vajont Reservoir in northern Italy on October 9, 1963, produced a 250-meter wave that overtopped the dam and killed approximately 1,917 people in the Piave Valley below. The disaster shaped subsequent Italian and NATO military infrastructure doctrine on dam and reservoir vulnerability assessment.
Ernesto "Che" Guevara was executed by Bolivian soldiers at a schoolhouse in La Higuera, Bolivia. The CIA-assisted operation ended the career of the twentieth century's most iconic revolutionary guerrilla fighter and made him a global symbol of resistance.
North Korea announced that it had successfully conducted its first underground nuclear test at the Punggye-ri test site. The device, estimated at less than one kiloton, was considered a partial failure by many analysts, but the test made North Korea the eighth declared nuclear state and dramatically escalated tensions in East Asia. The UN Security Council unanimously imposed sanctions.

The FIM-92 Stinger helped win the Cold War by turning Afghan mujahideen into a credible anti-aircraft threat. By 2023, the United States almost ran out of them, because Raytheon stopped making them for 13 years, and the first 10 months of Ukraine support burned through the remaining stockpile.
These weapons were built to fight a war that everyone prayed would never happen. The Minuteman III has been on alert since 1970. The Typhoon-class carried enough nuclear warheads to destroy a continent. The Davy Crockett could be fired by three soldiers. Most of them have been waiting for 40 years. Here are 10 Cold War weapons built exclusively for World War III.
The MiG-31 was designed to catch the SR-71 Blackbird. It is still the fastest fighter in any air force. The Foxhound's Zaslon phased-array radar, the first ever installed in a fighter, can track 10 targets and engage 4 simultaneously at ranges exceeding 200 miles. Here is why Russia still flies a 1980s interceptor, and why the MiG-31BM carrying a Kinzhal hypersonic missile has changed what the aircraft means to modern warfare.
Nineteen armies on four continents chose the Leopard 2. No other Western tank comes close to this export record, and the reasons go far beyond German engineering.
