World War II
Battle of Long Island
Brooklyn, New York

General William Howe's 20,000 British and Hessian troops outflanked and overwhelmed Washington's forces on the Heights of Guan in Brooklyn, inflicting roughly 2,000 American casualties against fewer than 400 British. Washington's subsequent nighttime evacuation across the East River saved the Continental Army from annihilation and allowed the revolution to continue.

Titusville Oil Strike
Titusville, Pennsylvania, USA

Edwin L. Drake, a former railroad conductor hired by the Seneca Oil Company, successfully drilled the first commercially productive oil well in the United States near Titusville, Pennsylvania. The well produced about 25 barrels a day, triggering an oil rush that transformed Pennsylvania's economy and set the template for the modern petroleum industry, from wildcat drilling to pipeline transport.

Krakatoa Explodes
10:02 AM · Sunda Strait, Dutch East Indies

At 10:02 a.m., the final and most violent of four explosions destroyed most of Krakatoa, ejecting an estimated 25 cubic kilometers of rock and ash and generating tsunamis up to 37 meters high. Over 36,000 people died, most drowned along the coastlines of Java and Sumatra. The blast was heard in Perth, Australia, and Rodrigues Island near Mauritius, some 3,000 miles distant.

World War II
Battle of Britain Rages
Southern England

During the Battle of Britain's critical late-August phase, RAF Fighter Command and the German Luftwaffe fought fierce engagements over southeastern England, with both sides suffering heavy aircraft losses. These weeks of attrition against RAF airfields and radar stations tested Britain's air defenses to their limit and ultimately forced Hitler to postpone Operation Sea Lion indefinitely.

Kamianets-Podilskyi Massacre
Kamianets-Podilskyi, Ukraine

Beginning around August 27, 1941, German SS and police battalions, aided by Hungarian and Ukrainian auxiliaries, shot more than 23,600 Jews, including many deported from Hungary, at pits outside Kamianets-Podilskyi. It stands as one of the largest mass shootings of the Holocaust prior to the more infamous Babi Yar massacre weeks later.

Politics
Lebanon's Constitutional Crisis
Beirut, Lebanon

Lebanon's parliament, elected weeks earlier, moved in late August 1943 to unilaterally amend the constitution to remove references to the French mandate, asserting full sovereignty. The Free French delegate-general responded with arrests of Lebanese leaders in November, provoking mass protests that forced France to release them and effectively concede Lebanese independence, achieved formally in 1943.

De Gaulle Consolidates Paris
Paris, France

Following the German garrison's surrender on August 25, General Charles de Gaulle spent August 27 consolidating political control of liberated Paris, meeting with resistance leaders and Allied officials to ensure that his Free French government, not rival factions within the Resistance, would govern France's future. His moves that week shaped postwar French politics for a generation.

Voyager 2 passed within 4,950 kilometers of Neptune's cloud tops, the final planetary encounter of its 12-year Grand Tour of the outer solar system. It discovered the Great Dark Spot storm system, six new moons, and geysers of nitrogen erupting on Triton, forever remaining humanity's only close-up look at Neptune.
