ground. He was sentenced to 21 days of solitary confinement and on 3 November was transferred to Camp No. 13 in Swanwick, Derbyshire, also known as the Hayes camp. In Camp No. 13, Werra joined a group calling itself A.G. (Swanwick Excavations, Ltd.), which was digging an escape tunnel. The tunnel can still be seen at the Hayes Conference Centre. On 17 December 1940, after a month's digging, it was complete. The camp had forgers who equipped the escape group with money and fake identity papers. On 20 December, Werra and four others slipped out of the tunnel under the cover of anti-aircraft fire and the singing of the camp choir. The others were recaptured quickly, leaving Werra to proceed alone. He had taken along his flying suit and decided to masquerade as Captain van Lott, a Dutch Royal Netherlands Air Force pilot. He told a friendly locomotive driver that he was a downed bomber pilot trying to reach his unit, and asked to be taken to the nearest RAF base. At Codnor Park railway station, a local clerk became suspicious but eventually agreed to arrange his transportation to the aerodrome at RAF Hucknall, near Nottingham. The police also questioned him but Werra convinced them he was harmless. At Hucknall, a Squadron Leader Boniface asked for his credentials and Werra claimed to be based at Dyce near Aberdeen. While Boniface went to check this story, Werra excused himself and ran to the nearest hangar, trying to tell a mechanic that he was cleared for a test flight. Boniface arrived in time to arrest him at gunpoint, as he sat in the cockpit, trying to learn the controls. Werra was sent back to the Hayes camp under armed guard. In January 1941, Werra was sent with many other German prisoners to Canada on the , in a convoy departing Greenock on 10 January 1941, guarded by among others. His group was to be taken to a camp on the north shore of Lake Superior, Ontario, so Werra began to plan his escape to the United States, which was still neutral. On 21 January, while on a prison train that had departed Montreal, he jumped out of a window, again with the help of other prisoners and ended up near Smiths Falls, Ontario, 30 miles from the St. Lawrence River. Seven other prisoners tried to escape from the same train but were
