The Channel is thought to have prevented
Neanderthals from colonising Britain during the Last Interglacial/Eemian, though they returned to Britain during the Last Glacial Period when sea levels were lower. The Channel has in historic times been both an easy entry for seafaring people and a key natural defence, halting invading armies while in conjunction with control of the North Sea allowing Britain to blockade the continent. For nearly a thousand years, the Channel also provided a link between the
Celtic Britons and
Armorica, with modern Brittany being founded by British settlers during the
Migration Period. 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. 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, the
Norman Conquest in 1066 and the
Glorious Revolution of 1688, while the concentration of excellent harbours in the Western Channel on Britain's south coast made possible the largest amphibious invasion in history, the
Normandy Landings in 1944. Channel
naval battles include the
Battle of the Downs (1639),
Battle of Dover (1652), the
Battle of Portland (1653) and the
Battle of La Hougue (1692). In
February 1684, ice formed on the sea in a belt wide off the coast of
Kent and wide on the French side.
Route to Britain Remnants of a
Mesolithic boatyard have been found on the
Isle of Wight.
Wheat was traded across the Channel about 8,000 years ago. "... Sophisticated social networks linked the
Neolithic front in southern Europe to the Mesolithic peoples of northern Europe." The
Ferriby Boats,
Hanson Log Boats and the later
Dover Bronze Age Boat could carry a substantial cross-Channel cargo.
Diodorus Siculus and Pliny both suggest trade between the rebel Celtic tribes of
Armorica and
Iron Age Britain flourished. In 55 BC
Julius Caesar invaded, claiming that the Britons had aided the
Veneti against him the previous year. He was more successful in
54 BC, but Britain was not fully established as part of the
Roman Empire until
Aulus Plautius's
43 AD invasion. A brisk and regular trade began between ports in Roman
Gaul and those in Britain. This traffic continued until the
end of Roman rule in Britain in 410 AD, after which the
early Anglo-Saxons left less clear historical records. In the power vacuum left by the retreating Romans, the Germanic
Angles,
Saxons, and
Jutes began the next great migration across the North Sea. Having already been used as mercenaries in Britain by the Romans, many people from these tribes crossed during the
Migration Period, conquering and perhaps displacing the native
Celtic populations.
Norsemen and Normans lies in the bay off
Saint Helier and is accessible on foot at low tide. The attack on
Lindisfarne in 793 is generally considered the beginning of the
Viking Age. For the next 250 years the Scandinavian raiders of Norway, Sweden, and Denmark dominated the North Sea, raiding monasteries, homes, and towns along the coast and along the rivers that ran inland. According to the
Anglo-Saxon Chronicle they began to settle in Britain in 851. They continued to settle in the
British Isles and the continent until around 1050, with some raids recorded along the channel coast of England, including at Wareham, Portland, near Weymouth and along the river Teign in Devon. The
fiefdom of Normandy was created for the
Viking leader
Rollo (also known as Robert of Normandy). Rollo had besieged Paris but in 911 entered
vassalage to the king of the
West Franks Charles the Simple through the
Treaty of St.-Claire-sur-Epte. In exchange for his
homage and
fealty, Rollo legally gained the territory he and his Viking allies had previously conquered. The name "Normandy" reflects Rollo's Viking (i.e. "Northman") origins. The descendants of Rollo and his followers adopted the local
Gallo-Romance language and intermarried with the area's inhabitants and became the
Normans – a
Norman French-speaking mixture of
Scandinavians,
Hiberno-Norse,
Orcadians,
Anglo-Danish, and indigenous
Franks and
Gauls. , depicting ships coming in and horses landing Rollo's descendant
William, Duke of Normandy, became king of England in 1066 in the
Norman Conquest beginning with the
Battle of Hastings, while retaining the fiefdom of Normandy for himself and his descendants. In 1204, during the reign of
King John, mainland Normandy was taken from England by France under
Philip II, while insular Normandy (the
Channel Islands) remained under English control. In 1259,
Henry III of England recognised the legality of French possession of mainland Normandy under the
Treaty of Paris. His successors, however, often fought to regain control of mainland Normandy. With the rise of
William the Conqueror, the North Sea and Channel began to lose some of their importance. The new order oriented most of England and Scandinavia's trade south, toward the
Mediterranean and the Orient. Although the British surrendered claims to mainland Normandy and other French possessions in 1801, the monarch of the United Kingdom retains the title Duke of Normandy in respect to the Channel Islands. The Channel Islands (except for
Chausey) are
Crown Dependencies of the
British Crown. Thus the
Loyal toast in the Channel Islands is
Le roi, notre Duc ("The King, our Duke"). The British monarch is understood to
not be the Duke of Normandy in regards of the French region of Normandy described herein, by virtue of the
Treaty of Paris of 1259, the surrender of French possessions in 1801, and the belief that the rights of succession to that title are subject to
Salic Law which excludes inheritance through female heirs. French Normandy was occupied by English forces during the
Hundred Years' War in 1346–1360 and again in 1415–1450.
England and Britain: Naval superpower off the English coast in 1588 From the reign of
Elizabeth I, English foreign policy concentrated on preventing invasion across the Channel by ensuring no major European power controlled the potential Dutch and Flemish invasion ports. Her climb to the pre-eminent
sea power of the world began in 1588 as the attempted invasion of the
Spanish Armada was defeated by the combination of outstanding naval tactics by the English and the Dutch under command of
Charles Howard, 1st Earl of Nottingham with
Sir Francis Drake second in command, and the following stormy weather. Over the centuries the
Royal Navy slowly grew to be the most powerful in the world. which ended the
French invasion plans in 1759 The building of the
British Empire was possible only because the
Royal Navy eventually managed to exercise unquestioned control over the seas around Europe, especially the Channel and the North Sea. During the
Seven Years' War, France attempted to
launch an invasion of Britain. To achieve this France needed to gain control of the Channel for several weeks, but was thwarted following the British naval victory at the
Battle of Quiberon Bay in 1759 and was unsuccessful (The last French landing on English soil being in 1690 with a raid on Teignmouth, although the last French raid on British soil was a raid on Fishguard, Wales in 1797). Another significant challenge to British domination of the seas came during the
Napoleonic Wars. The
Battle of Trafalgar took place off the coast of Spain against a combined French and Spanish fleet and was won by Admiral
Horatio Nelson, ending
Napoleon's plans for a cross-Channel invasion and securing British dominance of the seas for over a century.
First World War The exceptional strategic importance of the Channel as a tool for blockading was recognised by the First Sea Lord
Admiral Fisher in the years before
World War I. "Five keys lock up the world! Singapore, the Cape,
Alexandria, Gibraltar, Dover." However, on 25 July 1909
Louis Blériot made the first Channel crossing from
Calais to
Dover in an aeroplane. Blériot's crossing signalled a change in the function of the Channel as a barrier-moat for England against foreign enemies. Because the
Kaiserliche Marine surface fleet could not match the British Grand Fleet, the Germans developed
submarine warfare, which was to become a far greater threat to Britain. The
Dover Patrol, set up just before the war started, escorted cross-Channel troopships and prevented submarines from sailing in the Channel, obliging them to travel to the Atlantic via the much longer route around Scotland. On land, the
German army attempted to capture French Channel ports in the
Race to the Sea but although the trenches are often said to have stretched "from the frontier of Switzerland to the English Channel", they reached the coast at the North Sea. Much of the British war effort in
Flanders was a bloody but successful strategy to prevent the Germans reaching the Channel coast. At the outset of the war, an attempt was made to block the path of
U-boats through the Dover Strait with
naval minefields. By February 1915, this had been augmented by a stretch of light steel netting called the
Dover Barrage, which it was hoped would ensnare submerged submarines. After initial success, the Germans learned how to pass through the barrage, aided by the unreliability of British mines. On 31 January 1917, the Germans resumed
unrestricted submarine warfare leading to dire Admiralty predictions that submarines would defeat Britain by November, the most dangerous situation Britain faced in either world war. The
Battle of Passchendaele in 1917 was fought to reduce the threat by capturing the submarine bases on the Belgian coast, though it was the introduction of
convoys and not capture of the bases that averted defeat. In April 1918 the Dover Patrol carried out the
Zeebrugge Raid against the U-boat bases. During 1917, the Dover Barrage was re-sited with improved mines and more effective nets, aided by regular patrols by small warships equipped with powerful searchlights. A German attack on these vessels resulted in the
Battle of Dover Strait in 1917. A much more ambitious attempt to improve the barrage, by installing eight massive concrete towers across the strait was called the
Admiralty M-N Scheme but only two towers were nearing completion at the end of the war and the project was abandoned. The naval blockade in the Channel and North Sea was one of the decisive factors in the German defeat in 1918.
Second World War 1940 During the
Second World War, naval activity in the
European theatre was primarily
limited to the Atlantic. During the
Battle of France in May 1940, the
German forces succeeded in capturing both
Boulogne and
Calais, thereby threatening the line of retreat for the
British Expeditionary Force. By a combination of hard fighting and German indecision, the port of
Dunkirk was kept open allowing 338,000 Allied troops to be evacuated in
Operation Dynamo. More than 11,000 were evacuated from
Le Havre during
Operation Cycle and a further 192,000 were evacuated from ports further down the coast in
Operation Aerial in June 1940. The early stages of the
Battle of Britain featured German air attacks on Channel shipping and ports; despite these early successes against shipping the Germans did not win the
air supremacy necessary for
Operation Sealion, the projected cross-Channel invasion. The Channel subsequently became the stage for an intensive coastal war, featuring submarines,
minesweepers, and
Fast Attack Craft. The narrow waters of the Channel were considered too dangerous for major warships until the
Normandy Landings with the exception, for the German
Kriegsmarine, of the
Channel Dash (Operation Cerberus) in February 1942, and this required the support of the
Luftwaffe in
Operation Thunderbolt. , between 1940 and 1945 the occupying
German forces and the
Organisation Todt constructed fortifications round the coasts of the Channel Islands, such as this observation tower at Les Landes, Jersey.
Dieppe was the site of an ill-fated
Dieppe Raid by Canadian and British armed forces. More successful was the later
Operation Overlord (
D-Day), a massive invasion of
German-occupied France by
Allied troops.
Caen,
Cherbourg,
Carentan,
Falaise and other Norman towns endured many casualties in the fight for the province, which continued until the closing of the so-called
Falaise gap between
Chambois and
Montormel, then liberation of
Le Havre. The Channel Islands were the only part of the
British Commonwealth occupied by Germany (excepting the part of
Egypt occupied by the
Afrika Korps at the time of the
Second Battle of El Alamein, which was a protectorate and not part of the Commonwealth). The German occupation of 1940–1945 was harsh, with some island residents being taken for
slave labour on the Continent; native Jews sent to
concentration camps;
partisan resistance and retribution; accusations of
collaboration; and slave labour (primarily Russians and eastern Europeans) being brought to the islands to build fortifications. The
Royal Navy blockaded the islands from time to time, particularly following the
liberation of mainland Normandy in 1944. Intense negotiations resulted in some
Red Cross humanitarian aid, but there was considerable hunger and privation during the occupation, particularly in the final months, when the population was close to starvation. The German troops on the islands surrendered on 9 May 1945, a day after the final surrender in mainland Europe.
English Channel migrant crossings (2018–present) There is significant public concern in the UK about illegal immigrants coming on small boats from France. Since 2018, the English Channel has seen a major increase in the number of crossings. == Population ==
