This Day in History: Sep 7, 1776: World's first submarine attack



On this day in 1776, during the Revolutionary War, the American submersible craft Turtle attempts to attach a time bomb to the hull of British Admiral Richard Howe's flagship Eagle in New York Harbor. It was the first use of a submarine in warfare.


Submarines were first built by Dutch inventor Cornelius van Drebel in the early 17th century, but it was not until 150 years later that they were first used in naval combat. David Bushnell, an American inventor, began building underwater mines while a student at Yale University. Deciding that a submarine would be the best means of delivering his mines in warfare, he built an eight-foot-long wooden submersible that was christened the Turtle for its shape. Large enough to accommodate one operator, the submarine was entirely hand-powered. Lead ballast kept the craft balanced.

Donated to the Patriot cause after the outbreak of war with Britain in 1775, Ezra Lee piloted the craft unnoticed out to the 64-gun HMS Eagle in New York Harbor on September 7, 1776. As Lee worked to anchor a time bomb to the hull, he could see British seamen on the deck above, but they failed to notice the strange craft below the surface. Lee had almost secured the bomb when his boring tools failed to penetrate a layer of iron sheathing. He retreated, and the bomb exploded nearby, causing no harm to either the Eagle or the Turtle.

During the next week, the Turtle made several more attempts to sink British ships on the Hudson River, but each time it failed, owing to the operator's lack of skill. Only Bushnell was really able to competently execute the submarine's complicated functions, but because of his physical frailty he was unable to pilot the Turtle in any of its combat missions. During the Battle of Fort Lee, the Turtle was lost when the American sloop transporting it was sunk by the British.

Despite the failures of the Turtle, General George Washington gave Bushnell a commission as an Army engineer, and the drifting mines he constructed destroyed the British frigate Cereberus and wreaked havoc against other British ships. After the war, he became commander of the U.S. Army Corps of Engineers stationed at West Point.

This Day in History: Sep 6, 1915: First tank produced

On this day in 1915, a prototype tank nicknamed Little Willie rolls off the assembly line in England. Little Willie was far from an overnight success. It weighed 14 tons, got stuck in trenches and crawled over rough terrain at only two miles per hour. However, improvements were made to the original prototype and tanks eventually transformed military battlefields.

The British developed the tank in response to the trench warfare of World War I. In 1914, a British army colonel named Ernest Swinton and William Hankey, secretary of the Committee for Imperial Defence, championed the idea of an armored vehicle with conveyor-belt-like tracks over its wheels that could break through enemy lines and traverse difficult territory. The men appealed to British navy minister Winston Churchill, who believed in the concept of a "land boat" and organized a Landships Committee to begin developing a prototype. To keep the project secret from enemies, production workers were reportedly told the vehicles they were building would be used to carry water on the battlefield (alternate theories suggest the shells of the new vehicles resembled water tanks). Either way, the new vehicles were shipped in crates labeled "tank" and the name stuck.

The first tank prototype, Little Willie, was unveiled in September 1915. Following its underwhelming performance--it was slow, became overheated and couldn’t cross trenches--a second prototype, known as "Big Willie," was produced. By 1916, this armored vehicle was deemed ready for battle and made its debut at the First Battle of the Somme near Courcelette, France, on September 15 of that year. Known as the Mark I, this first batch of tanks was hot, noisy and unwieldy and suffered mechanical malfunctions on the battlefield; nevertheless, people realized the tank's potential. Further design improvements were made and at the Battle of Cambrai in November 1917, 400 Mark IV’s proved much more successful than the Mark I, capturing 8,000 enemy troops and 100 guns.

Tanks rapidly became an important military weapon. During World War II, they played a prominent role across numerous battlefields. More recently, tanks have been essential for desert combat during the conflicts in the Persian Gulf.

This Day in History: Aug 24, 79: Vesuvius erupts



After centuries of dormancy, Mount Vesuvius erupts in southern Italy, devastating the prosperous Roman cities of Pompeii and Herculaneum and killing thousands. The cities, buried under a thick layer of volcanic material and mud, were never rebuilt and largely forgotten in the course of history. In the 18th century, Pompeii and Herculaneum were rediscovered and excavated, providing an unprecedented archaeological record of the everyday life of an ancient civilization, startlingly preserved in sudden death.


The ancient cities of Pompeii and Herculaneum thrived near the base of Mount Vesuvius at the Bay of Naples. In the time of the early Roman Empire, 20,000 people lived in Pompeii, including merchants, manufacturers, and farmers who exploited the rich soil of the region with numerous vineyards and orchards. None suspected that the black fertile earth was the legacy of earlier eruptions of Mount Vesuvius. Herculaneum was a city of 5,000 and a favorite summer destination for rich Romans. Named for the mythic hero Hercules, Herculaneum housed opulent villas and grand Roman baths. Gambling artifacts found in Herculaneum and a brothel unearthed in Pompeii attest to the decadent nature of the cities. There were smaller resort communities in the area as well, such as the quiet little town of Stabiae.

At noon on August 24, 79 A.D., this pleasure and prosperity came to an end when the peak of Mount Vesuvius exploded, propelling a 10-mile mushroom cloud of ash and pumice into the stratosphere. For the next 12 hours, volcanic ash and a hail of pumice stones up to 3 inches in diameter showered Pompeii, forcing the city's occupants to flee in terror. Some 2,000 people stayed in Pompeii, holed up in cellars or stone structures, hoping to wait out the eruption.


A westerly wind protected Herculaneum from the initial stage of the eruption, but then a giant cloud of hot ash and gas surged down the western flank of Vesuvius, engulfing the city and burning or asphyxiating all who remained. This lethal cloud was followed by a flood of volcanic mud and rock, burying the city.


The people who remained in Pompeii were killed on the morning of August 25 when a cloud of toxic gas poured into the city, suffocating all that remained. A flow of rock and ash followed, collapsing roofs and walls and burying the dead.


Much of what we know about the eruption comes from an account by Pliny the Younger, who was staying west along the Bay of Naples when Vesuvius exploded. In two letters to the historian Tacitus, he told of how "people covered their heads with pillows, the only defense against a shower of stones," and of how "a dark and horrible cloud charged with combustible matter suddenly broke and set forth. Some bewailed their own fate. Others prayed to die." Pliny, only 17 at the time, escaped the catastrophe and later became a noted Roman writer and administrator. His uncle, Pliny the Elder, was less lucky. Pliny the Elder, a celebrated naturalist, at the time of the eruption was the commander of the Roman fleet in the Bay of Naples. After Vesuvius exploded, he took his boats across the bay to Stabiae, to investigate the eruption and reassure terrified citizens. After going ashore, he was overcome by toxic gas and died.

According to Pliny the Younger's account, the eruption lasted 18 hours. Pompeii was buried under 14 to 17 feet of ash and pumice, and the nearby seacoast was drastically changed. Herculaneum was buried under more than 60 feet of mud and volcanic material. Some residents of Pompeii later returned to dig out their destroyed homes and salvage their valuables, but many treasures were left and then forgotten.


In the 18th century, a well digger unearthed a marble statue on the site of Herculaneum. The local government excavated some other valuable art objects, but the project was abandoned. In 1748, a farmer found traces of Pompeii beneath his vineyard. Since then, excavations have gone on nearly without interruption until the present. In 1927, the Italian government resumed the excavation of Herculaneum, retrieving numerous art treasures, including bronze and marble statues and paintings.
The remains of 2,000 men, women, and children were found at Pompeii. After perishing from asphyxiation, their bodies were covered with ash that hardened and preserved the outline of their bodies. Later, their bodies decomposed to skeletal remains, leaving a kind of plaster mold behind. Archaeologists who found these molds filled the hollows with plaster, revealing in grim detail the death pose of the victims of Vesuvius. The rest of the city is likewise frozen in time, and ordinary objects that tell the story of everyday life in Pompeii are as valuable to archaeologists as the great unearthed statues and frescoes. It was not until 1982 that the first human remains were found at Herculaneum, and these hundreds of skeletons bear ghastly burn marks that testifies to horrifying deaths.

Today, Mount Vesuvius is the only active volcano on the European mainland. Its last eruption was in 1944 and its last major eruption was in 1631. Another eruption is expected in the near future, would could be devastating for the 700,000 people who live in the "death zones" around Vesuvius.
