King Henry VIII of England and King Francis I of France signed a treaty at the extravagant diplomatic summit known as the Field of the Cloth of Gold, pledging mutual military support against the Holy Roman Emperor Charles V, though the alliance ultimately proved fragile and short-lived.

Henry VIII of England and Francis I of France signed a treaty of mutual defence.

The agreement bound the two kings to support one another against outside aggression, reflecting the shifting alliances of the period as Henry's break from Rome over his divorce from Catherine of Aragon isolated England diplomatically. Anglo-French relations of the era remained volatile, and such treaties were often short-lived amid the broader rivalry between France, England and the Holy Roman Empire.

English ships intercepted and sank the Portuguese treasure carrack Cinco Chagas near the Azores.

The heavily laden vessel, returning from the East Indies with a valuable cargo, caught fire during the engagement with English raiders and sank with enormous loss of life, including many enslaved people held aboard.

Following Britain's acquisition of Acadia under the Treaty of Utrecht, colonial authorities issued the ultimatum to the region's French-speaking settlers. Many Acadians resisted taking the oath and remained in a state of uneasy neutrality for decades, a standoff that eventually culminated in their forced mass expulsion by British forces in the 1750s.

British forces under Robert Clive win a decisive victory over a much larger Indian army at the Battle of Plassey, cementing British control over Bengal.

British forces under Robert Clive won a decisive and lopsided victory over a vastly larger army commanded by the Nawab of Bengal at the Battle of Plassey, a triumph achieved partly through bribery and betrayal within the Nawab's own ranks that established British East India Company control over Bengal.

Robert Clive led British East India Company forces to a decisive victory over a much larger Bengali army at the Battle of Plassey.

Clive's outnumbered troops defeated the Nawab of Bengal's army with the help of a bribed defecting commander, Mir Jafar, who withheld his forces from the fighting. The victory gave the East India Company effective control of Bengal, one of the richest provinces in India, and is widely regarded as the foundation of British colonial rule on the subcontinent.

Commanded by Ferdinand of Brunswick, the allied army routed French forces near the Rhine city of Krefeld, temporarily securing western Germany for Britain's coalition.

Britain revoked the Orders in Council that had restricted American trade, removing a key cause of the War of 1812.

The Orders in Council had authorised the Royal Navy to blockade French ports and seize neutral ships trading with Napoleon's Europe, provoking fierce American resentment.

The Canadian Parliament passed legislation establishing Banff National Park, the country's first national park, protecting a stunning mountainous region around natural hot springs in Alberta that had been discovered by railway workers years earlier.

A German Focke-Wulf Fw 190 fighter mistakenly landed intact at RAF Pembrey in Wales.

Disoriented after a dogfight over the English Channel, the German pilot believed he was landing at a French airfield and touched down at the RAF base instead, delivering one of the Luftwaffe's most advanced fighters into British hands undamaged. The captured aircraft allowed British engineers to study the Fw 190 in detail and develop effective countermeasures.
