After his capture and interrogation, Heyda was interned in the Bowmanville POW Camp near Toronto, Canada.  He and other U-boat officers were involved in an uprising known as the Battle of Bowmanville when German prisoners were handcuffed in retaliation for the cuffing of Canadians taken at Dieppe.  Heyda later escaped from Bowmanville and traveled over 850 miles across Canada to meet a U-536 which BdU had ordered to wait off Maisonnette Point, New Brunswick.  The Allies were aware of the plan, having discovered coded messages in mail between BdU and the officers in the Bowmanville POW Camp.  Heyda was captured on the beach and U 536 narrowly escaped.
