British forces and their Native American allies crossed the Niagara River and burned the city of Buffalo, New York, along with the village of Black Rock, in retaliation for the American burning of Newark (Niagara-on-the-Lake) earlier that month.

American Minister James Gadsden and Mexican President Antonio Lopez de Santa Anna signed the Gadsden Purchase treaty in Mexico City, transferring approximately 29,670 square miles of territory in what is now southern Arizona and southwestern New Mexico to the United States for $10 million. The purchase completed the continental border of the United States and secured the route for the planned southern transcontinental railroad.

Spanish colonial authorities executed Filipino nationalist José Rizal by firing squad in Manila, transforming him into a martyr who galvanized the Philippine Revolution and whose legacy would shape American military involvement in the Philippines for half a century.

Russian nobles assassinated Grigori Rasputin, the mystic who had wielded enormous influence over Czar Nicholas II and Czarina Alexandra. His death destabilized the already fragile Russian monarchy, accelerating the chain of events that led to the Russian Revolution and the collapse of the Imperial Russian Army.

The last major reconnaissance patrols of Brigadier General John J. Pershing's Punitive Expedition reported from positions near Ojinaga, Chihuahua.

The USSR was officially established, uniting Russia, Ukraine, Belorussia, and the Transcaucasus into the superpower that would define global military competition for seventy years.

Soviet test pilot Mikhail Gromov completed a non-stop endurance flight of 75 hours aboard the Tupolev ANT-25 long-range research aircraft, setting a world record for closed-circuit endurance flight that demonstrated the feasibility of very long-range aircraft for strategic military missions. The ANT-25 design became the basis of several Soviet record-setting transcontinental flights during the 1930s including the 1937 flight from Moscow to San Jacinto, California, over the North Pole.

Operation Linebacker II ended after eleven nights of B-52 strikes against Hanoi and Haiphong, with North Vietnamese negotiators having signaled willingness to return to the Paris peace talks. The campaign dropped approximately 15,000 tons of bombs, lost 15 B-52s and 11 other aircraft to North Vietnamese SA-2 surface-to-air missiles, and shaped the final American approach to concluding direct involvement in the Vietnam War.

Former Iraqi dictator Saddam Hussein was executed by hanging at a joint Iraqi-American military base in Baghdad, following his conviction for crimes against humanity by an Iraqi tribunal, closing a chapter in Middle Eastern military history that had spanned three decades of conflict.

Saddam Hussein, the former President of Iraq, was hanged at an Iraqi government facility in the Kadhimiya neighborhood of Baghdad after conviction by the Iraqi Special Tribunal for crimes against humanity. The execution took place three years after his capture by American forces at a rural compound near Tikrit and closed one chapter of the Iraq War while the insurgency against American and Iraqi security forces continued at elevated intensity.
