Blitzkrieg is a method of warfare where the attacker spearheads an offence using a rapid overwhelming force concentration that may consist of armoured and motorised or mechanised infantry formations with close air support, with the intent to break through the opponent's line of defence by short, fast, and powerful attacks and then dislocates the defenders, using speed and surprise to encircle them with the help of air superiority. Through the employment of combined arms in manoeuvre warfare, blitzkrieg attempts to unbalance the enemy by making it difficult for it to respond to the continuously changing front, then defeat it in a decisive Vernichtungsschlacht.
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all the great powers—forming two opposing military alliances: the Allies and the Axis. In a state of total war, directly involving more than 100 million personnel from more than 30 countries, the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, resulting in 70 to 85 million fatalities, with more civilians than military personnel killed. Tens of millions of people died due to genocides, premeditated death from starvation, massacres, and disease. Aircraft played a major role in the conflict, including in strategic bombing of population centres, the development of nuclear weapons, and the only two uses of such in war.
The Western Front was the main theatre of war during the First World War. Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France. The German advance was halted with the Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trenches, stretching from the North Sea to the Swiss frontier with France, which changed little except during early 1917 and in 1918.
The Battle of Britain was a military campaign of the Second World War, in which the Royal Air Force (RAF) and Fleet Air Arm (FAA) of the Royal Navy defended the United Kingdom (UK) against large-scale attacks by Nazi Germany's air force, the Luftwaffe. It has been described as the first major military campaign fought entirely by air forces. The British officially recognise the battle's duration as being from 10 July until 31 October 1940, which overlaps the period of large-scale night attacks known as the Blitz, that lasted from 7 September 1940 to 11 May 1941. German historians do not accept this subdivision and regard the battle as a single campaign lasting from July 1940 to June 1941, including the Blitz.
The Battle of Dunkirk was fought in Dunkirk (Dunkerque), France, during the Second World War, between the Allies and Nazi Germany. As the Allies were losing the Battle of France on the Western Front, the Battle of Dunkirk was the defence and evacuation to Britain of British and other Allied forces in Europe from 26 May to 4 June 1940.
The Battle of France, also known as the Fall of France, was the German invasion of France, Belgium, Luxembourg and the Netherlands during the Second World War. On 3 September 1939, France had declared war on Germany, following the German invasion of Poland. In early September 1939, France began the limited Saar Offensive. By mid-October, the French had withdrawn to their start lines. The Germans invaded Belgium, Luxembourg and the Netherlands on 10 May, Italy entered the war on 10 June 1940 and German forces defeated the Allies on 25 June. France and the Low Countries were conquered, ending land operations on the Western Front until the Normandy landings on 6 June 1944.
The Dunkirk evacuation, code-named Operation Dynamo and also known as the Miracle of Dunkirk, was the evacuation of Allied soldiers during World War II from the beaches and harbour of Dunkirk, in the north of France, between 26 May and 4 June 1940. The operation commenced after large numbers of Belgian, British, and French troops were cut off and surrounded by German troops during the six-week Battle of France. In a speech to the House of Commons, British Prime Minister Winston Churchill called this "a colossal military disaster", saying "the whole root and core and brain of the British Army" had been stranded at Dunkirk and seemed about to perish or be captured. In his "we shall fight on the beaches" speech on 4 June, he hailed their rescue as a "miracle of deliverance".
The Panzergrenadier Division "Großdeutschland", also commonly referred to simply as Großdeutschland or Großdeutschland Division, was an elite combat unit of the German Army (Heer) that fought on the Eastern Front in World War II.
The Syria–Lebanon campaign, also known as Operation Exporter, was the British invasion of Vichy French Syria and Lebanon from June–July 1941, during the Second World War. The French had ceded autonomy to Syria in September 1936, with the right to maintain armed forces and two airfields in the territory.
The French 1st Cavalry Brigade was a military unit of the French Army which served during World War II. A partly horse-mounted unit, it fought in the Battle of Belgium and the Battle of France in May 1940. An element of the brigade was noted for its defence of Vendresse against German tanks, delaying their opponents for most of the day. After the Armistice of 22 June 1940 the brigade was reformed as a unit of Vichy France, but it was disbanded in November 1942.
No. 302 Polish Fighter Squadron RAF was a Polish fighter squadron formed in Great Britain as part of an agreement between the Polish Government in Exile and the United Kingdom in 1940. It was one of several Polish fighter squadrons fighting alongside the Royal Air Force during World War II.
Kampfgeschwader 4 "General Wever" was a Luftwaffe bomber wing during World War II. The unit was formed in May 1939. The unit operated the Dornier Do 17, Junkers Ju 88 and Heinkel He 111 medium bombers, with later service on the Heinkel He 177 heavy bomber. The wing was named after General Walther Wever, the prime pre-war proponent for a strategic bombing capability for the Luftwaffe, who was killed in an aircraft accident in 1936.
Kampfgeschwader 77 was a Luftwaffe bomber wing during World War II. Its units participated on all of the major fronts in the European Theatre until its dissolution in 1944. It operated all three of the major German bomber types; the Dornier Do 17, Heinkel He 111 and the Junkers Ju 88.
The Siege of Lille, or Lille Pocket, took place during the Battle of France in the Second World War. The siege around the city of Lille took place between the French IV Corps and V Corps of the First Army and four German infantry divisions supported by three panzer divisions.
The Wehrmacht was the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe. The designation "Wehrmacht" replaced the previously-used term Reichswehr, and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted.
The following events occurred in May 1940:
Haddock Force was the name given to a number of Royal Air Force bombers dispatched to airfields in southern France to bomb northern Italian industrial targets, once Italy declared war, which was thought to be imminent. Italy entered the Second World War on 10 June and the plan was put into effect but at first, the local French authorities prevented the RAF Vickers Wellington bombers from taking off. Whitleys flying from England via the Channel Islands made the first raid on the night of 11/12 June 1940.
The French destroyer Milan was one of six Aigle-class destroyer (contre-torpilleurs) built for the French Navy in the interwar period.
Commander-in-Chief, Home Forces was a senior officer in the British Army during the First and Second World Wars. The role of the appointment was firstly to oversee the training and equipment of formations in preparation for their deployment overseas, and secondly, to command the forces required to defend the United Kingdom against an enemy incursion or invasion.
