Question: When was the Invasion of Normandy took place?
Context: Operation Epsom, also known as the First Battle of the Odon, was a British Second World War offensive that took place between 26 and 30 June 1944, during the Battle of Normandy.  The offensive was intended to outflank and seize the German-occupied city of Caen, an important Allied objective, in the early stages of Operation Overlord, the Allied invasion of north-west Europe. Gold, commonly known as Gold Beach, was the code name for one of the five areas of the Allied invasion of German-occupied France in the Normandy landings on 6 June 1944, during the Second World War.  Gold, the central of the five areas, was located between Port-en-Bessin on the west and La Rivière on the east.  High cliffs at the western end of the zone meant that the landings took place on the flat section between Le Hamel and La Rivière, in the sectors code-named Jig and King.  Taking Gold was to be the responsibility of the British Army, with sea transport, mine sweeping, and a naval bombardment force provided by the Royal Navy as well as elements from the Dutch, Polish and other Allied navies. Exercise Tiger, or Operation Tiger, was the code name for one in a series of large-scale rehearsals for the D-Day invasion of Normandy, which took place in April 1944 on Slapton Sands in Devon.  Coordination and communication problems resulted in friendly fire deaths during the exercise, and an Allied convoy positioning itself for the landing was attacked by E-boats of Nazi Germany's "Kriegsmarine", resulting in the deaths of at least 749 American servicemen.  Because of the impending invasion of Normandy, the incident was under the strictest secrecy at the time and was only nominally reported afterwards. The Battle of Douvres Radar Station was military engagement of World War II as part of the Invasion of Normandy, that took place the on 17 June 1944.  The attack was by British 41 Commando, Royal Marines, the station and area were defended mainly by "Luftwaffe" ground forces.  Preceded by an artillery bombardment and supported by mine-clearing and anti-bunker tanks of 79th Armoured Division, the Marines were able to secure the surrender of the garrison. The Western Allies of World War II launched the largest amphibious invasion in history when they assaulted Normandy, located on the northern coast of France, on 6 June 1944.  The invaders were able to establish a beachhead as part of Operation Overlord after a successful "D-Day," the first day of the invasion. H-hour was the name given to the airborne assault during the Normandy landings of World War II.  The units involved included the U.S. 101st Airborne Division and U.S. 82nd Airborne Division, along with the British 6th Airborne Division.  This took place about three hours before the main beach landings on the Normandy.  The airborne invasion consisted of over 20,000 men and around 1,200 planes and gliders.  The combined assault of the three Allied airborne divisions would surprise the German defenders and cause enough havoc behind the German lines, enabling the beach landings to go more smoothly. Virgil John Tangborn (May 23, 1920 - June 14, 1944) PFC, U.S. Army, and Silver Star recipient for gallantry, was mortally wounded by enemy shellfire during the Invasion of Normandy on June 14, 1944 at the small village of Amfreville in Normandy, France.  He was rescuing a wounded soldier trapped in a burning truck containing exploding ammunition.  The action took place during ensuing explosions within a burning and heavily shelled artillery ammunition dump.  He is the brother of Wendell Tangborn, American glaciologist. The Allied invasion of Italy was the Allied amphibious landing on mainland Italy that took place on 3 September 1943 during the early stages of the Italian Campaign of World War II.  The operation was undertaken by General Sir Harold Alexander's 15th Army Group (comprising General Mark W. Clark and General Bernard Montgomery's British Eighth Army) and followed the successful invasion of Sicily.  The main invasion force landed around Salerno on 9 September on the western coast in Operation Avalanche, while two supporting operations took place in Calabria (Operation Baytown) and Taranto (Operation Slapstick). The Battle of Saint-Lô is one of the three conflicts in the , which took place between July 9–24, 1944, just before Operation Cobra.  Saint-Lô had fallen to Germany in 1940, and, after the Invasion of Normandy, the Americans targeted the city, as it served as a strategic crossroads.  American bombardments caused heavy damage (up to 95% of the city was destroyed) and a high number of casualties, which resulted in the martyr city being called "The Capital of Ruins", popularized in a report by Samuel Beckett. Operation Perch was a British offensive of the Second World War which took place from 7 to 14 June 1944, during the early stages of the Battle of Normandy.  The operation was intended to encircle and seize the German occupied city of Caen, which was a D-Day objective for the British 3rd Infantry Division in the early phases of Operation Overlord.  Operation Perch was to begin immediately after the British beach landings with an advance to the south-east of Caen by XXX Corps.  Three days after the invasion the city was still in German hands and the operation was amended.  The operation was expanded to include I Corps for a pincer attack on Caen.
