I am a committee member of the Fortress Study Group, writing regularly for the journal Fort and the magazine Casemate. I also write regularly for Military History Matters. I am also a member of the Battlefields Trust and Pike and Shot Society.
Much of my research is undertaken ‘in the field’: understanding the topography of a site is just as important as a knowledge of the events which surround it. I have travelled extensively throughout the British Isles and across Europe, and as far afield as North America and South Africa visiting fortifications and siege-sites. I was honoured with the award of Fellowship of the Royal Geographical Society in 2013 and am part of the Society’s Discovering Britain project.
