Welcome to D-Day This blog is made by students of the 5th C of secondary school Santa Maria Marianists. We are Bernardo La Rosa, Luis Ignacio Garcia-Miro and Alonso Monsalve. In this blog we will talk about D-Day and the strategy used in Normandy.

What is the D-Day

The "D-Day" is a military term use to refer  the start of any combat operation and / or attack. Popularly  the D-Day is refer to the 6 of June of 1944, opening day of Operation Overlord; warfare operation that took place during the 2nd World War on the beaches of Normandy. This attack was for the  attack, invade and liberate France and Europe German control.
The terms D-Day and H-Hour are terms used when a day or time of an attack is still not give or when it is in secret, and these must be unique for all participating units.
The original  Day of the Normandy attack was the 5 of June of  1944, but poor weather and sea, causing a change for the 6 of June, giving more time to rehearse the attack acts Because this latter date is popularly known as the small D-Day

The Battle of Normandy, Operation Overlord was originally called the invasion of Europe by the Allies in the northwest of France, which at that time was occupied by the Germans, was implemented during the 2nd World War. 
Preparations for the operation started in Britain, this was the initial battle and one of the most important and defining the wars, which started freeing Europe from German control.

At first it was intended to attack Italy but in 1944 there was a strengthening in this area and decided to switch to Normandy. For Operation Overlord armies were involved mainly U.S. and British imperial army, along with support French forces, Polish, Belgium, Greek, etc.

The Normandy attack was called Operation Neptune, and it was so amazing that 68 years remains the largest seaborne invasion operation in history.

Why did the Allies choose Normandy?

The Germans were expecting the allies to land at the beaches of Calais, because it would have been much more strategic. The allies knew that so they sent "dummies" to Calais to deliver men away from Normandy.
"The Allies tried to decieve the Germans into believing that the landing had to be at Pas de Calais. That included bombing the area. On the day of the landings, they dropped dummy paratroopers(no, not stupid paratroopers, but dummy models of them)."

Allies and Axis Strategies

Allies strategy:

The order of battle for the landings were from east to west

- The british second army consisted of 83,115 troops conformed by British and Canadian men.

  • 6th Airborne Division Commanded by Major-General R.N. Gale was delivered by parachute and glider to the east of the River Orne to protect the left flank. The division contained 7,900 men, including one Canadian battalion.The British 2nd Army landed three divisions on D-Day. Two were from I Corps and one from XXX Corps on Sword Beach, Gold Beach, and Juno Beach.

German Strategy:

- "The military forces  of Nazi Germany reached its peak 1944. By D-Day, 157 German divisions were stationed in the Soviet Union, 6 in Finland, 12 in Norway, 6 in Denmark, 9 in Germany, 21 in the Balkans, 26 in Italy and 59 in France, Belgium and the Netherlands. However, these statistics are somewhat misleading since a significant number of the divisions in the east were depleted due to intensity of fighting; German records indicate that the average personnel complement was at about 50% in the spring of 1944"

"The German defenses used an interlocking firing style, so they could protect areas that were receiving heavy fire. They had large bunkers, sometimes intricate concrete ones containing machine guns and large-calibre weapons. Their defence also integrated the cliffs and hills overlooking the beaches. The defenses were all built and refined over a four year period."

Planning the invansion

General Eisenhower was the supreme comander from da d-day attack, their was a new plan assembled and their were preparde began 1943. The attacked occured 1944.
Normandy was chosen for the landings because it was in range of fighter aircraft based in England and had open beaches that were not as well defended as those of the Pas de Calais. Beforde d-day the Allied air forces wrecked the railways and bridges of northern France and achieved the necessary weakening of German air force strength. Other preparations included the manufacture of equipment including transport ships, landing craft, amphibious tanks and artificial harbours. For the war they mobilize materials and human huge. For the ships would download their package and passangers.

The attack of Normandy was delayed a day because hte  weather problems, which helped the Alliedto practice and perfect there strategy. Something that was fundamental for the attack was the now common and everyday used pocket watch, which helped the general timing the attack perfectly. This operation was a success and is  known as the best landing and invasion operation of all time.
