Operation Overlord in the context of "French Resistance"

Dwight David "Ike" Eisenhower (born David Dwight Eisenhower; October 14, 1890 – March 28, 1969) was the 34th president of the United States, serving from 1953 to 1961. During World War II, he was Supreme Commander of the Allied Expeditionary Force in Europe and achieved the five-star rank as General of the Army. Eisenhower planned and supervised two of the most consequential military campaigns of World War II: Operation Torch in the North Africa campaign in 1942–1943 and the invasion of Normandy in 1944.

Eisenhower was born in Denison, Texas, and raised in Abilene, Kansas. His family had a strong religious background, and his mother became a Jehovah's Witness. Eisenhower, however, belonged to no organized church until 1952. He graduated from West Point in 1915 and later married Mamie Doud, with whom he had two sons. During World War I, he was denied a request to serve in Europe and instead commanded a unit that trained tank crews. Between the wars he served in staff positions in the US and the Philippines, reaching the rank of brigadier general shortly before the entry of the US into World War II in 1941. After further promotion Eisenhower oversaw the Allied invasions of North Africa and Sicily before supervising the invasions of France and Germany. After the war ended in Europe, he served as military governor of the American-occupied zone of Germany (1945), Army Chief of Staff (1945–1948), president of Columbia University (1948–1953), and as the first supreme commander of NATO (1951–1952).

The air war during Operation Overlord, alongside the Battle of Britain, the carrier battles in the Pacific and the strategic air war against the German Reich, was one of the most significant air battles of the Second World War. It took place between April and August 1944 in the course of the Allied landings in northern France (→ Operation Overlord).

The Allied landing in Normandy was also made possible by the air superiority of the Allied forces. Before June 6, 1944, known as D-Day, the Allied air forces prepared for the invasion. They bombed German supply lines, artillery batteries and supported the French Resistance from the air with ammunition and equipment.

Matthew Bunker Ridgway (3 March 1895 – 26 July 1993) was a senior officer in the United States Army, who served as Supreme Allied Commander Europe (1952–1953) and the 19th Chief of Staff of the United States Army (1953–1955). Although he saw no combat service in World War I, he was intensively involved in World War II, where he was the first Commanding General (CG) of the 82nd Airborne Division, leading it in action in Sicily, Italy and Normandy, before taking command of the newly formed XVIII Airborne Corps in August 1944. He held the latter post until the end of the war in mid-1945, commanding the corps in the Battle of the Bulge, Operation Varsity and the Western Allied invasion of Germany.

Ridgway held several major commands after World War II and is most well-known for resurrecting the United Nations (UN) war effort during the Korean War. Several historians have credited Ridgway for turning the war around in favor of the UN side. He also persuaded President Dwight D. Eisenhower to refrain from direct military intervention in the First Indochina War to support French colonial forces, thereby essentially delaying the United States' Vietnam War by over a decade. He received the Presidential Medal of Freedom on 12 May 1986. Ridgway died in 1993 at the age of 98.

The Tehran Conference (codenamed Eureka) was a strategy meeting of the Allies of World War II, held between Joseph Stalin, Franklin D. Roosevelt, and Winston Churchill from 28 November to 1 December 1943. It was the first of the Allied World War II conferences involving the "Big Three" (the Soviet Union, the United States, and the United Kingdom) and took place at the Soviet embassy in Tehran just over a year after the Anglo-Soviet invasion of Iran. The meeting occurred shortly after the Cairo Conference was held in Egypt for a discussion between the United States, the United Kingdom, and China from 22 to 26 November 1943. The Big Three would not meet again until 1945, when the Yalta Conference was held in Crimea from 4 to 11 February and the Potsdam Conference was held in Allied-occupied Germany from 17 July to August 2. Notably, President Franklin D. Roosevelt arrived on the USS Iowa.

Although the three leaders arrived in Tehran with differing objectives, the main outcome of the meeting was a British and American commitment to opening a second front against Nazi Germany, thereby forcing it to pull military assets away from the Eastern Front with the Soviets. In addition to this decision, the Tehran Conference also addressed: the Big Three's relations with Turkey and Iran, as the former was being pressed to enter the conflict and the latter was under Allied occupation; operations in Yugoslavia and against Japan; and the envisaged settlement following the expected defeat of the Axis powers. A separate contract also saw the Big Three pledge to recognize Iranian independence.

The Provisional Government of the French Republic (PGFR; French: Gouvernement provisoire de la République française, GPRF) was the provisional government of Free France between 3 June 1944 and 27 October 1946, following the liberation of continental France after Operations Overlord and Dragoon, and lasting until the establishment of the French Fourth Republic. Its establishment marked the official restoration and re-establishment of a provisional French Republic, assuring continuity with the defunct French Third Republic.

It succeeded the French Committee of National Liberation (CFLN), which had been the provisional government of France in the overseas territories and metropolitan parts of the country (Algeria and Corsica) that had been liberated by the Free French. As the wartime government of France in 1944–1945, its main purposes were to handle the aftermath of the occupation of France and continue to wage war against Germany as one of the major Allies.

A beachhead is a temporary line created when a military unit reaches a landing beach by sea and begins to defend the area as other reinforcements arrive. Once a large enough unit is assembled, the invading force can begin advancing inland. The term is sometimes used interchangeably (both correctly and incorrectly) with bridgehead and lodgement. Beachheads have been important in many military actions; examples include operations such as Operation Neptune during World War II, the Korean War (especially at Inchon), and the Vietnam War.

Although many references state that Operation Neptune refers to the naval operations in support of Operation Overlord, the most reliable references make it clear that Overlord referred to the establishment of a large-scale lodgement in Normandy, and that Neptune referred to the landing phase which created the beachhead; Neptune was therefore the first part of Overlord. According to the D-Day Museum:

Rouen (UK: /ˈruːɒ̃, ˈruːɒn/, US: /ruːˈɒ̃, ruːˈɒn/; French: [ʁwɑ̃] or [ʁu.ɑ̃]) is a city on the River Seine, in northwestern France. It is in the prefecture of region of Normandy and the department of Seine-Maritime. Formerly one of the largest and most prosperous cities of medieval Europe, the population of the metropolitan area (French: aire d'attraction) is 702,945 (2018). People from Rouen are known as Rouennais.

Rouen was the seat of the Exchequer of Normandy during the Middle Ages. It was one of the capitals of the Anglo-Norman and Angevin dynasties, which ruled both England and large parts of modern France from the 11th to the 15th centuries. From the 13th century onwards, the city experienced a remarkable economic boom, thanks in particular to the development of textile factories and river trade. Claimed by both the French and the English during the Hundred Years' War, it was on its soil that Joan of Arc was tried and burned alive on 30 May 1431. Severely damaged by the wave of bombing in 1944, it nevertheless regained its economic dynamism in the post-war period thanks to its industrial sites and its large seaport, which merged with the ports of Le Havre and Paris in 2021 to form the HAROPA Port.

Operation Dragoon (initially Operation Anvil), known as Débarquement de Provence in French ("Provence Landing"), was the code name for the landing operation of the Allied invasion of Provence (Southern France) on 15 August 1944. Although initially designed to be executed in conjunction with Operation Overlord, the June 1944 Allied landing in Normandy, the lack of enough resources led to the cancellation of the second landing. By July 1944 the landing was reconsidered, as the clogged-up ports in Normandy did not have the capacity to adequately supply the Allied forces. Concurrently, the high command of the French Liberation Army pushed for a revival of the operation, which would involve large numbers of French troops. As a result, the operation was finally approved in July to be executed in August.

The invasion sought to secure the vital ports on the French Mediterranean coast and increase pressure on the German forces by opening another front. After preliminary commando operations, the US VI Corps landed on the beaches of the Côte d'Azur under the protection of a large naval task force, followed by several divisions of French Army B. They were opposed by the scattered forces of the German Army Group G, which had been weakened by the relocation of its divisions to other fronts and the replacement of its soldiers with third-rate Ostlegionen outfitted with obsolete equipment.
