My Google news alerts went crazy with all of these articles on the Bosworth Field investigation! Here is my last post on the subject and I’ve linked to several of today’s stories below this excerpt from the Guardian article:
Five centuries of searching for one of Britain’s most significant battlefields has finally ended with the discovery of “extraordinary and unexpected” pieces of artillery in a Leicestershire field.
The finds near Market Bosworth at last pin down the notoriously “wandering site” of the battle that overthrew Richard III

There is more information (including a lot of pictures of the artifacts they have found so far) at the Official Bosworth site.
Maybe the cannon, and pistol’s had something to do with the battles outcome?!
