Bit odd this, not quite sure what to make of it - it's certainly an unconventional approach - but a publisher has initiated a discussion thread soliciting historical fiction manuscripts:
http://www.amazon.co.uk/forum/historical%20fiction/ref=cm_cd_dp_rft_tft_tp?_encoding=UTF8&cdForum=Fx2ZSX7XQX5JZM8&cdThread=TxTP0ISLWP463N
The Publisher is Pen & Sword, which I've heard of. At the moment, they publish military history (non-fic).

People are pitching their novels in the discussion thread.
