Please introduce the back garden operation in detail.

The Battle of the Market Garden1September, 944 17 (Sunday) is a good day for flying according to Western European standards. By nine o'clock in the morning, the fog had cleared at airports all over Britain, and the cloud height on the European continent remained above 5,000 feet. Just before dawn, hundreds of British and American fighters and bombers took off and flew to the Strait in formation. At this time, the British Second Army Corps was invading Holland and advancing to the lower reaches of the Rhine. At that time, the air force's ground target was in the north of the 2 nd legion. This is the beginning of "market action" and the first large-scale daytime air raid by the military since the German army captured Crete more than three years ago. When Montgomery's 2nd Army Corps advanced with airborne attack as the vanguard, the supplies of the 1st 1, 2nd and 7th Army Corps could only be kept to a minimum, and the 2nd Army Corps of Britain would advance to Suedeze across Albert and Escat Canal and intercept the Germans in the west of the Netherlands. This ground combat part is called "combat garden". Eisenhower wanted to go deep into these low-lying countries and seize the bridgehead on the Rhine River, so as to relieve the pressure on Antwerp. At the same time, he wondered whether it was possible to maintain the momentum of the offensive, cross France and enter the open plains of northern Germany. This test of the German residual resistance may become a decisive battle in Western Europe during the Great War. Montgomery is ready to advance on a very narrow front, which has never been tried by a large army; In fact, he took the whole army along a road through Ein-dhiven, Stoedendrode, wickel, Uden, Guenaff, Nijmegen, Arnhem and Apeldoorn. The task of paratroopers is to occupy the bridges along the road and keep them open. After the fighters crossed the sea and entered the Netherlands, they all descended to the height of the top of the tree, searched and attacked the anti-aircraft gun positions along the axis of the main road from the British area to the north, crossed the Val River in Naimegan and entered Anheng. Bombers continued to attack German operational airports in Leeuwarden, Steenwijk-Hauekte, Hopsten and Salzbergen, where flames were blazing and craters piled up on the runway. At 10 a.m., paratroopers and gliders took off from 24 airports in south central England. The transport plane dragged the glider down the runway and rushed into the early morning sky. Only planes climbing and turning are seen in the air. There are 1 13 1 fighter planes, 1545 transport planes and 478 gliders towed to form a fleet, which flies to the north sea in two ways. Twenty minutes before these formations, six British and 12 American air navigation groups transported the pilots to the marked landing zone. There were twenty thousand allied paratroopers, sweating like a pig, huddled on canvas chairs. Each one is hung with all kinds of straps, straps and bullets, and it is difficult to know how many. Everyone is fluctuating, confused and heading for Holland. All operations need to airlift 35,000 people to participate in the war, support 25,000 transport planes and glide down 24,000 times. The air force fleet is divided into two huge echelons: one is in the north, carrying the 82nd British Division and the 1 Airborne Division to reach the target area via Sauven Island in the Netherlands, and the other is in the south, which is used by1KLOC-0/Division. Each echelon plane is divided into three roads, and the left and right roads are one and a half miles away from the central road. This is the largest aircraft formation in history, and it carries three airborne divisions to fight at the same time. The transport planes transferred from the ninth US Army Transport Command and the 38th and 46th Brigade of the Royal Air Force are experienced pilots who landed in Normandy and fought in the south of France. Paratroopers of the 82nd Airborne Division have just returned from training in various training bases in Britain. Soldiers have experience in fighting in Sicily, Italy and Normandy. 10 1 division is also a veteran who landed in Normandy, and has been training for this parachute jump since late July. After returning from the battlefields in Africa, Sicily and Italy, the British 1st Airborne Division has been preparing for nearly nine months. As for the Polish 1 Paratrooper Brigade, it has been prepared in Britain for two years in order to return to the European continent. The fleet flew over Belgium and the Netherlands without interference from German fighters. Anti-aircraft fire is surprisingly weak. The southern echelon carrying the 10 1 airborne division encountered more anti-aircraft artillery fire, while the northern echelon had little. On the way, the US military lost 35 transport planes and 13 gliders. The British fleet did not lose anything on the way. The original plan was to airdrop three paratroopers in front of the main attack route of the 2 nd British Army Corps to occupy important terrain and bridges. Taylor's 1st 10 1 airborne division landed in Enhefen, which is 15 miles ahead, Gavin's 82nd airborne division landed in Nijmegen, which is 30 miles ahead, and urquhart's 1st airborne division occupied Anheng, which is further north 12 miles ahead. Half an hour after the air raid, the 30th Army launched an attack, with the Irish Guards Armored Division as the pioneer, marching along the road in column formation, joining forces with the airborne division in turn, and the paratroopers kept the road open. The army moved forward, crossed the lower reaches of the Rhine at Anheng, established a bridgehead, and prepared to continue to March on Germany. When this bold plan was conceived, it was the climax of a large-scale continuous pursuit of the Germans, and the defeated Germans were expelled back to their borders. The allied forces in the attacking forces acted quickly and the ground forces were invincible, so the plan of airborne reserve to participate in the war was all invalid. Within six weeks after the establishment of the Allied Airborne First Corps in Brayton, the staff officers of the Ministry drew up eighteen different operational plans, but these plans were cancelled one by one due to the continuous advancement of the vanguard troops on the ground. The selected targets of air strikes include more than ten places from chartres-Rambouillet in the Netherlands to Mainz and Mannheim in the German territory. The repeated cancellation of these plans and the lack of long-term planning guidance are the main reasons. These airborne combat plans were conceived by the low-level grass-roots personnel of the high-level command organization. Brayton later pointed out that the operational objectives of airborne troops and the coordination with all ground forces should be decided by Eisenhower and his staff. In fact, Brayton had to coordinate with other military commanders to decide his plan, but all military commanders thought he was competing with them for the transport plane. A senior staff officer told Bretton the prevailing view at that time. He said, "You are flying around there, so be careful not to get into trouble. If we are asked to solve your difficulties, supply you and support you, then we may not be able to complete our task. You can sit in the back and give us some supplements. Why on earth should we help you? Anyway, if the situation is difficult, Ike will give us one or two divisions-maybe one or two of yours. Commanders of various regiments are concerned about how to replenish their scattered troops at present. As for airborne operations, they may take away valuable planes, but of course they are not interested.
