On this day, 81 years ago, June 5, 1944 (April 15, 1944, the lunar calendar), Normandy landed. In the late period of World War II, the troops of the United States, Britain and other countries launched a landing campaign against German troops in the Normandy region of northwest France (Battle of Overlord). In 1944, the United States and Britain began to fulfill their commitment made at the Tehran Conference in November 1943 to open a second front in Europe, in view of the fact that the Soviet Union's victory over Germany was a foregone conclusion. On the night of June 5, 1944, three Allied airborne divisions airborne at a depth of 10 to 15 kilometers from the coast. On the morning of the 6th, the allied forces began assault landings in five locations. After fierce fighting, the landing sites were connected into one piece on the 12th, with a front width of about 80 kilometers and a depth of 12 to 18 kilometers. On July 5, 1 million people landed, and about 567,000 tons of supplies and 172,000 vehicles were transported ashore. On July 24, the battle ended. The Allied forces and the German forces invested 2.88 million and 510,000 respectively. The Allied forces eliminated a total of 114,000 German troops, destroyed 2117 tanks and 245 aircraft, and 122,000 Allied casualties. The victory of the Allied Forces put the German fascists in a dilemma of being attacked from both sides and changed the situation of the European battlefield.
