Henry was given one hour to pack before his internment journey began. He was held at temporary holding centres in Edinburgh and York before arriving at Warth Mills. The camp was already far exceeding its capacity and conditions were lamentable. For a boy of 16, separated from his family and accused of being a spy, it was a desperate situation.
After a few weeks, Henry was transferred to the Isle of Man. His fellow internees were artists, musicians and academics and, although still prisoners, they made the best of the situation and it provided a teenager like Henry with an opportunity to learn.
Henry underwent several tribunals, eventually being re-categorised and released.
