The past 10 years has seen an immense growth in the popularity of what has been known as Battlefield Archaeology. The interest has been stimulated from a wider spectrum of archaeology, which dealt with the recovery of human remains upon the battlefields of Western Europe, and the forensic investigations carried out upon sites of war-crimes such as Bosnia etc. Further, the development of Conflict-Heritage (battlefield tours and museums), and Conflict Studies, these subjects have bonded with archaeology -bringing together a new accedemic subject: Conflict Archaeology.
Today one can find many books upon the subject, of which a selection are list here:
Images of conflict
The Archaeology of 20th Century Conflict
Digging the Trenches: The Archaeology of the Western Front: Amazon.co.uk: Andrew Robertshaw, David Kenyon: Books
Digging up Plug Street
Authors such as Andy Robertshaw, David Kenyon and Nicholas J Saunders have stimulated a wider growth in accademic research into what is now termed "Conflict Archaeology" with their involvment in various TV productions. But Tony Pollard is probably the most widely publicised and experienced accedemic on Conflict Archaeology, and heads up Glasgow's 'Centre for Battlefield Archaeology'. Tony Pollard also helped to discover the recent mass graves of Fromelles - which contain both British and Austrialian Commonwealth troops.
As someone also pointed out, the journal for Conflict Archaeology can be found here and provides articles written by lesser known accedemics/experts from accross the world.
