. Lead elements of XXX Corps reached Driel the following day, but at the same time the Germans formed a blocking line to the west to prevent an Allied advance on the road bridge.

During the day the 1st Division sourced six rubber boats and again requested the Poles attempt to cross. That night (the 22nd) the plan was put into operation, but the tow rope designed to pull the boats across snapped, and the oars were too small to row against the river's current. 55 men crossed and only 35 were able to reach the British positions.

On the 23rd the 43rd Wessex Division arrived in strength and offered assault boats for the Poles. Unfortunately these arrived late and the Poles, unfamiliar with the craft, were only able to put 153 men across the river - less than a quarter of the hoped for reinforcement.

On the 24th, Horrocks himself visited the Polish positions to asses the situation. That afternoon a conference was held at Valburg

 of the 43rd (Wessex) Division outlined a plan to put across a battalion of his division and one of the Polish battalions - to the fury of their commander Major General Stanisław Sosabowski. Despite this it seems that Horrocks realised the futility of the paratroopers position and preliminary plans were drawn up for their withdrawal.

That night's attempt to cross the river was disastrous. Insufficient boats arrived for both battalions and so only the 4th Battalion The Dorsetshire Regiment made the attempt. Unfortunately their crossing led into prepared German positions and of the 315 men who crossed before daylight, over 200 were captured. Two men who did reach the Airborne forces carried copies of the withdrawal plan for Urquhart's consideration.

The Plan

At a conference between Miles Dempsey, Frederick Browning, and Brian Horrocks, it was decided that the British needed to be immediately evacuated from Arnhem.
Urquhart's plan called for small groups of men to thin out and span the Oosterbeek perimeter. Then, under cover of night, the main bulk of the force would slip across the river. The remaining defenders would slowly withdraw and soon they too would make it across the Rhine. To trick the Germans into thinking that the British were still fighting, radio traffic was planned to continue heavily and artillery would bombard the eastern shore of the Rhine to trick the Germans into thinking that there would be another landing to the east. Meanwhile, the division would go by boat across the Rhine to the village of Driel

 held by the Poles. The wounded would all be left behind to be cared for by the Germans.

Another part of Urquhart's plan called for the 4th Dorsets Battalion of the 43rd (Wessex) Infantry Division to be deployed across the Rhine prior to the British retreat. These forces would open up the base of the Oosterbeek Perimeter and prevent it from being bottled-up by the Germans while the 1st Airborne crossed to safety.

Outcome

Of the original 10,005 men who landed in Arnhem, 2,500 were fighting capable on the night of the 25th. Of these, 2,163 British, along with 160 Poles and 75 4th Dorsets, made it across the Rhine and into the safety of Driel.
