History
Before the end of the Devensian glaciation (the most recent ice age that ended around 10,000 years ago), the British Isles were part of continental Europe, linked by an unbroken Weald-Artois Anticline, which acted as a natural dam that held back a large freshwater pro-glacial lake in the Doggerland region, now submerged under the North Sea. During this period the North Sea and almost all of the British Isles were covered with ice. The lake was fed by meltwater from the Baltic and from the Caledonian and Scandinavian ice sheets that joined to the north, blocking its exit. The sea level was about 120 m (390 ft) lower than it is today. Then, more than 200,000 yBP a single catastrophic glacial lake outburst flood overtopped the Weald-Artois Anticline and scoured a channel through an expanse of low-lying tundra, right down to the underlying chalk bedrock. In a study published in 2007 high-resolution sonar revealed the unexpectedly well-preserved scourmarks and the telltale lenticular island forms characteristic of torrential flood. Through the scoured channel passed a river which now drained the combined Rhine and Thames towards the Atlantic to the west. As the ice sheet melted, a large freshwater lake formed in the southern part of what is now the North Sea. As the meltwater could still not escape to the north (as the northern North Sea was still frozen) the outflow channel from the lake entered the Atlantic Ocean in the region of Dover and Calais.
This precious stone set in the silver sea,
Which serves it in the office of a wall
Or as a moat defensive to a house,
Against the envy of less happier lands.
The Channel, which delayed human reoccupation of Great Britain for more than 100,000 years, has in historic times been the key natural defence for Britain, halting invading armies while in conjunction with control of the North Sea allowing Britain to blockade the continent. The most significant failed invasion threats came when the Dutch and Belgian ports were held by a major continental power, e.g. from the Spanish Armada in 1588, Napoleon during the Napoleonic Wars, and Nazi Germany during World War II. Successful invasions include the Roman conquest of Britain and the Norman Conquest in 1066, while the concentration of excellent harbours in the Western Channel on Britain's south coast made possible the largest invasion of all time, the Normandy landings in 1944. Channel naval battles include the Battle of Goodwin Sands (1652), the Battle of Portland (1653), the Battle of La Hougue (1692) and the engagement between USS Kearsarge and CSS Alabama (1864).
In more peaceful times the Channel served as a link joining shared cultures and political structures, particularly the huge Angevin Empire from 1135 to 1217. For nearly a thousand years, the Channel also provided a link between the Modern Celtic regions and languages of Cornwall and Brittany. Brittany was founded by Britons who fled Cornwall and Devon after Anglo-Saxon encroachment. In Brittany, there is a region known as "Cornouaille" (Cornwall) in French and "Kernev" in Breton In ancient times there was also a "Domnonia" (Devon) in Brittany as well.
In February 1684, ice formed on the sea in a belt 3 miles (4.8 km) wide off the coast of Kent and 2 miles (3.2 km) wide on the French side.

Famous quotes containing the word history:
“The thing that struck me forcefully was the feeling of great age about the place. Standing on that old parade ground, which is now a cricket field, I could feel the dead generations crowding me. Here was the oldest settlement of freedmen in the Western world, no doubt. Men who had thrown off the bands of slavery by their own courage and ingenuity. The courage and daring of the Maroons strike like a purple beam across the history of Jamaica.”
—Zora Neale Hurston (1891–1960)
“It may be well to remember that the highest level of moral aspiration recorded in history was reached by a few ancient Jews—Micah, Isaiah, and the rest—who took no count whatever of what might not happen to them after death. It is not obvious to me why the same point should not by and by be reached by the Gentiles.”
—Thomas Henry Huxley (1825–95)
“Three million of such stones would be needed before the work was done. Three million stones of an average weight of 5,000 pounds, every stone cut precisely to fit into its destined place in the great pyramid. From the quarries they pulled the stones across the desert to the banks of the Nile. Never in the history of the world had so great a task been performed. Their faith gave them strength, and their joy gave them song.”
—William Faulkner (1897–1962)
