August 24 in History

Gaius Scribonius Curio crossed into Africa in 49 BC with two legions, chasing Pompey's allies, certain he had the upper hand. He didn't. Publius Attius Varus had allied with King Juba of Numidia, whose cavalry Curio had already underestimated once. At the second Battle of the Bagradas River, Juba's forces surrounded and destroyed Curio's legions. Curio refused to flee. He stayed with his men and died with them. Caesar, who had sent him there, wrote about the defeat without quite acknowledging how much of it was Curio's overconfidence. He'd been a tribune, a gifted speaker, a loyal partisan. He was 30.

In 79 AD, Mount Vesuvius erupted, burying the cities of Pompeii, Herculaneum, and Stabiae in volcanic ash. This catastrophic event preserved these cities under layers of ash, providing invaluable archaeological insights into Roman life and culture, and remains one of the most studied volcanic eruptions in history.

Vandal king Genseric led his forces into Rome in 455 AD, and Pope Leo I negotiated a deal: no killing, no burning, in exchange for the gates being opened. The Vandals honored the terms on murder and arson but spent two weeks systematically stripping the city of its treasures, including sacred vessels from the Temple of Jerusalem.

The Ottoman Empire under Sultan Selim I crushed the Mamluk Sultanate at the Battle of Marj Dabiq in 1516, seizing control of Syria and opening the road to Egypt. The victory doubled the Ottoman Empire's territory within two years and established Ottoman dominance over the Middle East for four centuries.

The Crown mandated the 1662 Book of Common Prayer as the sole legal liturgy for the Church of England, instantly stripping over 2,000 clergy members of their positions. This enforcement triggered the Great Ejection, permanently fracturing English religious life by removing nonconformist voices from established parishes and pushing them into underground networks.

William Penn received the lower counties — the area now comprising Delaware — from the Duke of York on August 24, 1682. Penn had already received Pennsylvania from Charles II the previous year and had been looking for a water route to the sea that didn't depend on other colonial powers. Delaware gave him the Delaware River mouth. He added it to Pennsylvania under a joint legislature. The two territories shared governance uneasily for decades. Delaware formally separated in 1704. Penn's Frame of Government gave both territories more religious freedom than anywhere else in the English colonies at the time. Delaware kept the framework. It became the first state to ratify the Constitution.

Job Charnock of the East India Company established a trading post in Calcutta in 1690, an event long considered the city's founding — though in 2003, the Calcutta High Court ruled the city has no official birthday. Regardless of the ruling, the settlement Charnock built grew into one of the world's great cities and the capital of British India.

The Swedish army surrenders to Russian forces in Helsinki on August 24, 1743, bringing the War of the Hats to a decisive close. This capitulation forces Sweden to cede significant territory and formally ends its brief attempt to reclaim dominance over Finland through the Lesser Wrath period that follows.

A small force of Pennsylvania militia was ambushed by Native American warriors in 1781, devastating George Rogers Clark's planned expedition against the British-held fort at Detroit. The loss forced Clark to abandon one of the most ambitious American offensive operations of the Revolutionary War's western theater.

A coalition of Spanish, British, and Portuguese forces finally lifted the Siege of Cádiz in 1812, ending a two-and-a-half-year French blockade of the city. Cádiz had served as the seat of the Spanish government-in-exile during the siege, and its defense became a symbol of Spanish resistance to Napoleon.
