The Cuban Missile Crisis reached its most dangerous moment, later called "Black Saturday", when a Soviet surface-to-air missile shot down an American U-2 reconnaissance aircraft over Cuba, killing Major Rudolf Anderson Jr. Simultaneously, a Soviet submarine commander nearly launched a nuclear torpedo at the American naval blockade. The world stood at the very brink of thermonuclear war before Soviet Premier Khrushchev agreed to withdraw missiles from Cuba.
American and British diplomats began the preliminary peace negotiations in Paris that would lead to the Treaty of Paris ending the American Revolutionary War. Benjamin Franklin, John Adams, and John Jay represented the United States in talks with British envoy Richard Oswald. The resulting treaty, signed in September 1783, recognized American independence and established boundaries that doubled the territory of the new nation.
Napoleon Bonaparte entered Berlin in triumph following his devastating victories over Prussia at the twin battles of Jena and Auerstedt two weeks earlier. The Prussian Army, considered one of Europe's finest, had been shattered in a single day of fighting. Napoleon's occupation of Berlin, during which he issued the Berlin Decree establishing the Continental System to blockade British trade, represented the zenith of French military power in Europe.
Marshal Achille Bazaine surrendered the fortress of Metz to Prussian forces along with 173,000 French troops, one of the largest capitulations in military history. The garrison had been besieged since the Battle of Gravelotte in August, and its fall freed 200,000 Prussian soldiers to march on Paris. Bazaine was later court-martialed and sentenced to death for treason, though the sentence was commuted to imprisonment.
The Interborough Rapid Transit Company subway opened with an initial line running from City Hall to Harlem, introducing mass underground transit to New York City. The project was driven in part by military logisticians who had studied London's Underground and recognized rail transit as essential infrastructure for moving reservists and war material through major port cities in the event of mobilization.
The Greek Civil War effectively ended when communist guerrilla forces announced a ceasefire after suffering decisive defeats by the Greek National Army, supported by American military aid under the Truman Doctrine. The conflict, which had raged since 1946, was the first proxy war of the Cold War and the first test of the American policy of containment. Greece's survival as a Western-aligned democracy validated the Truman Doctrine and set the pattern for American Cold War interventions.
American M48 Patton tanks and Soviet T-54s faced each other at point blank range at the Checkpoint Charlie crossing between East and West Berlin after days of escalating confrontation over access rights. Ten tanks on each side sat with loaded main guns for sixteen hours before a negotiated withdrawal defused the standoff. It was the only direct tank confrontation between American and Soviet forces of the Cold War.
A Soviet missile shot down an American U-2 over Cuba, a Soviet submarine nearly launched a nuclear torpedo, and the world stood at the brink of thermonuclear war. Only the refusal of one Soviet naval officer to authorize a nuclear launch prevented catastrophe. The crisis was resolved the following day.
Soviet submarine B-59, pinned by American destroyers dropping practice depth charges near Cuba, debated whether to launch its nuclear tipped T-5 torpedo. Captain Valentin Savitsky and political officer Ivan Maslennikov voted to fire. Flotilla commander Vasili Arkhipov, whose concurrence was required under Soviet procedure, refused. His veto very likely prevented a tactical nuclear exchange and escalation to global war.
The Democratic Republic of the Congo was renamed the Republic of Zaire under President Mobutu Sese Seko on October 27, 1971, beginning a 26-year dictatorship that positioned the country as a major Cold War client of the United States and shaped Central African military geography for the remainder of the twentieth century.

Twenty-sixth President of the United States who transformed American military power and foreign policy. Roosevelt resigned as Assistant Secretary of the Navy to lead the Rough Riders in the charge up San Juan Hill during the Spanish-American War, earning the Medal of Honor. As president, he built the Panama Canal, sent the Great White Fleet around the world, modernized the U.S. Navy into a world-class force, and won the Nobel Peace Prize for mediating the Russo-Japanese War.
Prussian field marshal and military reformer who served as chief of staff to Field Marshal Blücher during the Napoleonic Wars. Gneisenau was the strategic brain behind the Prussian march to Waterloo in 1815, making the critical decision to move toward Wellington rather than retreat after the defeat at Ligny. His military reforms, alongside those of Scharnhorst, transformed the Prussian Army from a feudal force into the professional institution that would dominate European warfare for a century.
U.S. Air Force pilot who became the only combat fatality of the Cuban Missile Crisis when his U-2 reconnaissance aircraft was shot down by a Soviet SA-2 surface-to-air missile over Cuba on Black Saturday. Anderson, who had flown some of the first reconnaissance missions over Cuba that confirmed the presence of Soviet missiles, was posthumously awarded the Air Force Cross and the first-ever Air Force Distinguished Service Medal. His death nearly triggered the retaliatory strike that would have escalated to nuclear war.

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.
