In the morning of 18 September 1944, part of the 3^rd Parachute Battalion arrives in this area and is met by German opposition from the city. But German troops have also managed to cut the rest of the British 3^rd Parachute Battalion off at Oosterbeek-Laag station. The group that is stuck here has no option but to entrench themselves until the rest will be able to join. During this day, they have to pull back a few hundred metres.

It is not until late that day that the British manage to overcome German resistance at Oosterbeek-Laag and more British troops arrive in the area; not only of the 3^rd Parachute Battalion, but also of the 1^st Parachute Battalion. Later, a battalion of the South Staffordshires also follows. Though the paratroopers have suffered heavy losses and are anything but at full strength, this is a considerable group. The battalion commanders agree to mount a coordinated attack to reach the road bridge.

Due to a variety of circumstances, this coordination does not work in practice. When early in the morning the 1^st Parachute Battalion gets ready to fight via de open area of Onderlangs, they are amazed to see the poor remnants of the 3^rd battalion coming towards them from the other side. At night, they had completely independently made an attack that failed; now there are only some 50 men left of the more than 500 who landed on Renkum Heath. The 1^st Parachute Battalion, considerably thinned out as well, launches its attack. But when the sun comes up, they come under heavy fire from ahead and from the south bank of the Rhine. Although they manage to come close to the Old Port, lieutenant colonel Dobie has only 39 men left. Unable to pull back again, they entrench themselves in some houses. Around half past seven in the morning, they are made prisoners of war by the Germans. The attack via Onderlangs to reach the road bridge has failed.
