The Fashoda Incident
Britain vs. France1898September-November 1898French and British expeditions both arrived at a remote Sudanese fort on the Nile claiming it for their empires — the most dangerous confrontation between two allied nations in the Scramble for Africa, France ultimately backed down, the incident nearly caused a war between Europe's two largest colonial powers over a mud fort
The Suez Crisis
Egypt vs. Britain, France, Israel1956October-November 1956Egypt's Nasser nationalized the Suez Canal, so Britain, France, and Israel invaded — the US and USSR both condemned the invasion, forcing a humiliating withdrawal, the moment that proved the British Empire was truly over, and America and the Soviets now called the shots
The Ems Dispatch

The XYZ Affair
USA vs. France17971797-1800French diplomats (anonymized as X, Y, and Z) demanded bribes before agreeing to negotiate with American envoys — the American public was outraged, the slogan 'Millions for defense, but not one cent for tribute' captured the mood, led to an undeclared naval war (Quasi-War) between former allies
The Berlin Blockade
Soviet Union vs. USA, UK, France1948June 1948 - May 1949Stalin blocked all road, rail, and canal access to West Berlin hoping to force the Western Allies out — instead the Allies organized a massive airlift delivering 2.3 million tons of supplies over 15 months, planes landing every 30 seconds, the blockade backfired spectacularly and cemented Western resolve
The Dogger Bank Incident
Russia vs. Britain1904October 1904The Russian Baltic Fleet sailing to fight Japan somehow mistook British fishing trawlers in the North Sea for Japanese torpedo boats and opened fire — killed three fishermen and nearly triggered a war between Russia and Britain, one of history's most absurd friendly fire incidents, the fleet's incompetence foreshadowed its annihilation at Tsushima
The Iran Hostage Crisis

The Trent Affair

Germany vs. France, Britain1911July-November 1911Kaiser Wilhelm sent a gunboat to the Moroccan port of Agadir ostensibly to protect German interests but really to challenge French expansion — Britain sided firmly with France, the crisis hardened the Anglo-French alliance and pushed Europe closer to the alliances that would trigger World War I three years later
The Gulf of Tonkin Incident
USA vs. North Vietnam1964August 2-4, 1964The USS Maddox reported being attacked by North Vietnamese torpedo boats — the second alleged attack almost certainly never happened, but Congress passed the Gulf of Tonkin Resolution giving President Johnson authority to escalate military operations, the dubious pretext that plunged America into the Vietnam War
