World War II: Surviving elements of the British 1st Airborne Division withdraw from Arnhem in the Netherlands, thus ending the Battle of Arnhem and Operation Market Garden.

The Battle of Arnhem was a battle of the Second World War at the vanguard of the Allied Operation Market Garden. It was fought in and around the Dutch city of Arnhem, the town of Oosterbeek, the villages Wolfheze and Driel and the vicinity from 17 to 26 September 1944. The Allies were poised to enter the Netherlands after sweeping through France and Belgium in the summer of 1944, after the Battle of Normandy. Operation Market Garden was proposed by Field Marshal Sir Bernard Montgomery, who favoured a single push northwards over the branches of the Lower Rhine River, allowing the British Second Army to bypass the Siegfried Line and attack the Ruhr. US Airborne troops were dropped in the Netherlands to secure bridges and towns along the line of the Allied advance. Farthest north, the British 1st Airborne Division landed at Arnhem to capture bridges across the Nederrijn (Lower Rhine), supported by men of the Glider Pilot Regiment and the 1st Polish Parachute Brigade. The British XXX Corps were expected to reach the British airborne forces in two to three days.

The 1st Airborne Division landed some distance from its objectives and was hampered by unexpected resistance, especially from elements of the 9th and 10th SS Panzer Divisions. Only a small force was able to reach the Arnhem road bridge while the advance of the main body of the division was stopped on the outskirts of the town. XXX Corps was unable to advance north from Nijmegen as quickly as planned and the British airborne troops were not relieved according to schedule. After four days, the small British force at the bridge was overwhelmed and the rest of the division trapped in a small pocket north of the river. The British could not be sufficiently reinforced by the Poles or XXX Corps when they arrived on the southern bank, nor by Royal Air Force supply flights. After nine days of fighting, the remnants of the division were withdrawn in Operation Berlin. The Allies were unable to advance further with no secure bridges over the Nederrijn and the front line stabilised south of Arnhem. The British 1st Airborne Division lost nearly three quarters of its strength and did not see combat again.

The 1st Airborne Division was an airborne infantry division of the British Army during the Second World War. The division was formed in late 1941 during the Second World War, after the British Prime Minister, Winston Churchill, demanded an airborne force, and was initially under command of Major-General Frederick A. M. Browning. The division was one of two airborne divisions raised by the British Army during the war, with the other being the 6th Airborne Division, created in May 1943, using former units of the 1st Airborne Division.

The division's first two missions—Operation Biting, a parachute landing in France, and Operation Freshman, a glider mission in Norway—were both raids. Part of the division was sent to North Africa at the end of 1942, where it fought in the Tunisian Campaign, and when the Allies invaded Sicily in July 1943, the division undertook two brigade sized landings. The first, Operation Ladbroke, carried out by glider infantry of the 1st Airlanding Brigade and the second, Operation Fustian, by the 1st Parachute Brigade, were far from completely successful. The 1st Airborne Division then took part in a mostly diversionary amphibious landing, codenamed Operation Slapstick, as part of the Allied invasion of Italy in September 1943.

In December, most of the 1st Airborne Division (minus the 2nd Parachute Brigade) returned to England, and began training and preparing for the Allied invasion of Normandy. It was not involved in the Normandy landings in June 1944, being held in reserve. In September 1944 the 1st Airborne took part in Operation Market Garden. The division, with the Polish 1st Parachute Brigade temporarily attached, landed 60 miles (97 km) behind German lines, to capture crossings on the River Rhine, and fought in the Battle of Arnhem. After failing to achieve its objectives, the division was surrounded and took very heavy casualties, but held out for nine days before the survivors were evacuated.

The remnants of the 1st Airborne Division was returned to England soon after. The division never fully recovered from their losses at Arnhem and the 4th Parachute Brigade was disbanded. Just after the end of the war in Europe, the depleted formation took part in Operation Doomsday in Norway in May 1945. They were tasked with the disarmament and repatriation of the German occupation army. The 1st Airborne Division then returned to England and was disbanded in November 1945.
