Haven't got this yet, but it seems one to look out for. A previous book called Dangerous Energy; The Archaeology of Gunpowder and Military Explosives Manufacturing by Wayne Cockcroft et al touched on Gretna, so I'm hoping this book goes into a lot more detail- "Historic Scotland have documented the origins of Gretna for a new book, unearthing its forgotten history as a munitions town manufacturing artillery shells for the First World War. Gretna - A Munitions Town documents how the Borders community famous for its weddings was actually founded in 1915 spurred by a need to manufacture artillery shells to fuel the looming conflict, leading to over 20,000 homes being built over a two year period. Masterplanned by Raymond Unwin the town was built to a harmonious architectural style characterised by terraced and semi-detached brick houses – the most important of which have received grade B and C listings. These were built around an ambitious nine mile long complex of armaments factories along the Solway Firth to manufacture cordite for bullets and shells, of which almost nothing remains today." http://www.urbanrealm.com/news/3805...al_Gretna’s_wartime_origins_in_new_book.html?
