B. A. Egerton completed National Service in the Royal Air Force, which he extended to 12 years as a radar specialist. He adapted his training to become a computer and communications engineer with an international corporation and, finally, staff manager of its European Customer Services. After this, he obtained a place at the University of East Anglia to read History and in 2005 gained an honours degree. Following further research, he developed a course entitled ‘Britain in Conflict’, which he presented to adult education classes. He has since increased the breadth of his research to include Great Britain’s role in world affairs since its formation by the Act of Union between England and Scotland in 1707. In 2018, he was elected to membership of the Royal Historical Society.
