Because of his injury, Digby was sent to St Elizabeth's Hospital but escaped out of a window with his second in command Captain Tony Frank, when the German nurses had left them alone. After creating an escape compass from buttons on his uniform, Digby and Frank headed towards Mariendaal. Upon arriving, they were hidden by a Dutch woman who spoke no English before being put in contact with her neighbour. He disguised them as painters and moved them to Derk Wildeboer's house. Wildeboer was a local leader of the Dutch Resistance in Ede. They then met Menno de Nooy of the Dutch Resistance who gave them a bicycle. Wildeboer had a fake Dutch identity card made for Digby to allow him to pose as Peter Jensen, a deaf-mute son of a lawyer. Digby used the bicycle to visit fellow soldiers in hiding and the Germans did not recognise him despite him helping to push a Nazi staff car out of a ditch and German soldiers being billeted in the same house that he was staying in. Digby then gathered 150 escaped soldiers to head towards the front line. This was known as Operation Pegasus. Digby and the soldiers cycled to the Rhine and Digby flashed a V for Victory sign using Morse Code with his torch. Members of XXX Corps then ferried them across the river. Upon return to the United Kingdom, Digby was awarded the Distinguished Service Order. He also wrote a report on the Battle of Arnhem Bridge that resulted in Lieutenant Jack Grayburn's posthumously receiving a promotion to captain and being awarded the Victoria Cross.
