The Normandy landings were the landing operations on Tuesday, 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during World War II. Codenamed Operation Neptune and often referred to as D-Day, it was the largest seaborne invasion in history. The operation began the liberation of German-occupied France (and later Europe) from Nazi control, and laid the foundations of the Allied victory on the Western Front.

Planning for the operation began in 1943. In the months leading up to the invasion, the Allies conducted a substantial military deception, codenamed Operation Bodyguard, to mislead the Germans as to the date and location of the main Allied landings. The weather on D-Day was far from ideal and the operation had to be delayed 24 hours; a further postponement would have meant a delay of at least two weeks as the invasion planners had requirements for the phase of the moon, the tides, and the time of day that meant only a few days each month were deemed suitable. Adolf Hitler placed German Field Marshal Erwin Rommel in command of German forces and of developing fortifications along the Atlantic Wall in anticipation of an Allied invasion.

The amphibious landings were preceded by extensive aerial and naval bombardment and an airborne assault—the landing of 24,000 US, British, and Canadian airborne troops shortly after midnight. Allied infantry and armoured divisions began landing on the coast of France at 06:30. The target 50-mile (80 km) stretch of the Normandy coast was divided into five sectors: Utah, Omaha, Gold, Juno, and Sword. Strong winds blew the landing craft east of their intended positions, particularly at Utah and Omaha. The men landed under heavy fire from gun emplacements overlooking the beaches, and the shore was mined and covered with obstacles such as wooden stakes, metal tripods, and barbed wire, making the work of the beach-clearing teams difficult and dangerous. Casualties were heaviest at Omaha, with its high cliffs. At Gold, Juno, and Sword, several fortified towns were cleared in house-to-house fighting, and two major gun emplacements at Gold were disabled, using specialised tanks.

The Allies failed to achieve any of their goals on the first day. Carentan, St. Lô, and Bayeux remained in German hands, and Caen, a major objective, was not captured until 21 July. Only two of the beaches (Juno and Gold) were linked on the first day, and all five beachheads were not connected until 12 June; however, the operation gained a foothold which the Allies gradually expanded over the coming months. German casualties on D-Day have been estimated at 4,000 to 9,000 men. Allied casualties were at least 10,000, with 4,414 confirmed dead.

43-7-5 Unternehmen Zitadelle - Battle of Kursk

Unternehmen Zitadelle 

The Battle of Kursk was a Second World War engagement between German and Soviet forces on the Eastern Front near Kursk (450 kilometres or 280 miles south-west of Moscow) in the Soviet Union, during July and August 1943. The battle began with the launch of the German offensive, Operation Citadel (German: Unternehmen Zitadelle), on 5 July, which had the objective of pinching off the Kursk salient with attacks on the base of the salient from north and south simultaneously. After the German offensive stalled on the northern side of the salient, on 12 July the Soviets commenced their Kursk Strategic Offensive Operation with the launch of Operation Kutuzov (Russian: Кутузов) against the rear of the German forces in the northern side. On the southern side, the Soviets also launched powerful counterattacks the same day, one of which led to a large armoured clash, the Battle of Prokhorovka. On 3 August, the Soviets began the second phase of the Kursk Strategic Offensive Operation with the launch of Operation Polkovodets Rumyantsev (Russian: Полководец Румянцев) against the German forces in the southern side of the Kursk salient.

The battle was the final strategic offensive that the Germans were able to launch on the Eastern Front. Because the Allied invasion of Sicily had begun, Adolf Hitler was forced to have troops training in France diverted to meet the Allied threat in the Mediterranean, rather than use them as a strategic reserve for the Eastern Front. Hitler canceled the offensive at Kursk after only a week, in part to divert forces to Italy. Germany's extensive losses of men and tanks ensured that the victorious Soviet Red Army enjoyed the strategic initiative for the remainder of the war.

The Germans hoped to weaken the Soviet offensive potential for the summer of 1943 by cutting off the forces that they anticipated would be in the Kursk salient. The Kursk salient or bulge was 250 kilometres (160 mi) long from north to south and 160 kilometres (99 mi) from east to west. The plan envisioned an envelopment by a pair of pincers breaking through the northern and southern flanks of the salient. Hitler believed that a victory here would reassert German strength and improve his prestige with his allies, who were considering withdrawing from the war. It was also hoped that large numbers of Soviet prisoners would be captured to be used as slave labour in the German armaments industry.

The Soviet government had foreknowledge of the German intentions, provided in part by the British intelligence service and Tunny intercepts. Aware months in advance that the attack would fall on the neck of the Kursk salient, the Soviets built a defence in depth designed to wear down the German armoured spearhead. The Germans delayed the offensive while they tried to build up their forces and waited for new weapons, mainly the new Panther tank but also larger numbers of the Tiger heavy tank. This gave the Red Army time to construct a series of deep defensive belts. The defensive preparations included minefields, fortifications, artillery fire zones and anti-tank strong points, which extended approximately 300 km (190 mi) in depth. Soviet mobile formations were moved out of the salient and a large reserve force was formed for strategic counter-offensives.

The Battle of Kursk was the first time in the Second World War that a German strategic offensive was halted before it could break through enemy defences and penetrate to its strategic depths. The maximum depth of the German advance was 8–12 kilometres (5.0–7.5 mi) in the north and 35 kilometres (22 mi) in the south. Though the Red Army had succeeded in winter offensives previously, their counter-offensives following the German attack at Kursk were their first successful strategic summer offensives of the war.
