I work in Historic England's Landscape Archaeology Team. I started my career working on archaeological excavations at home and abroad. For the last 30 years, or so, I've specialised in the investigation of historic defence and industrial sites.
In early summer 1940, Britain had been seriously weakened following the evacuation from Dunkirk of the core of its professional army. It left the country alone in the fight against Hitler.
Sites associated with warfare, from Roman forts and medieval castles to Victorian coastal fortifications, are some of our most prominent historic monuments.
