King Leonidas of Sparta and his 300 Spartans, along with several thousand other Greek allies, made their legendary last stand against the Persian army of Xerxes I at the narrow pass of Thermopylae. The three-day battle became the Western world's most celebrated example of courage against overwhelming odds.

Spain and the United States signed an armistice ending the Spanish-American War after just ten weeks of fighting. The brief conflict resulted in Spain ceding Cuba, Puerto Rico, Guam, and the Philippines to the United States, transforming America into an imperial power with military commitments spanning the globe.

The Battle of Amiens entered its fourth day as Allied forces continued to press the German retreat. Though the initial momentum was slowing as troops outran their artillery support, the German army had suffered a moral collapse that Ludendorff acknowledged made continued resistance futile.

The German airship LZ 127 Graf Zeppelin crossed the Atlantic bound for Friedrichshafen on the first leg of the first circumnavigation of the globe by an airship. The 21-day flight demonstrated the operational range of rigid airships and intensified U.S. Navy interest in lighter-than-air craft for long-range fleet reconnaissance.

The most heavily defended convoy of the war, Operation Pedestal, fought through massive Axis air, submarine, and surface attacks to deliver desperately needed supplies to the besieged island of Malta. Of fourteen merchant ships, only five reached port, but their cargo saved Malta from starvation and surrender.

Hussein bin Talal was proclaimed King of Jordan at age 17 following the assassination of his grandfather King Abdullah.

The U.S. Air Force and Navy recovered the Discoverer 13 reentry capsule after it splashed down near Hawaii, the first object ever returned intact from orbit.

Six days of rioting erupted in the Watts neighborhood of Los Angeles after a traffic stop escalated into violence. Governor Pat Brown deployed 14,000 National Guard troops to restore order. The deployment highlighted the growing tensions between military-style policing and civilian communities that would characterize American domestic unrest for decades.

The 3rd Battalion, 21st Infantry Regiment, the last American ground combat unit in Vietnam, departed Da Nang for the United States.

The Croatian Army completed the consolidation phase of Operation Storm, a four-day offensive that recaptured the self-declared Republic of Serbian Krajina and broke Serbian military power in Croatia.
