The book is a collaborative effort between my self, Dr Summerfield and my brother on Napoleonic Artillery. Overall it has good reviews though some reviewers have come to a conclusion its a sort of 'fairy tale' book about artillery as it is not pro french.
The full reference is:
Dawson A L, Dawson P L, Summerfield S (2007) Napoleonic Artillery Crowood Press Gloucester
Also worth looking at are the AnXI plans and notes prepared by Dr Summerfield
Dawson P L Summerfield S (2008) French Artillery of 1824 DG&P Doncaster - a look at French AnXI artillery, a general overview. I hope at some point to produce a monograph on French artillery between 1790 and 1820. I have most of this written. Feel free to email me off the board for any assistance in obtaining these books or information on French artillery.
