I found both his books I've read so far to be very engaging, not at all muddled - despite the breadth of the subjects, a good pace but not hurried. Certainly as good as Trigg or Holland for example.He (along with several veterans) was a guide when my Staff College course toured the battlefieldin that year.
I have posted MP3 recordings of all of them bar one* on the web (try the Pegasus Archive for links)
He was a very good speaker.
His written style, however, left much to be desired. I seriously hope he's improved with time.
* I still have not found the cassette on which I recorded the stories told by a bloke who was a Pl Comd at the bridge, to my lasting regret.
