I am sorry to report that John Tiller died on 26 April. Although he was not a specialist in Napoleonic history he was the founder of John Tiller Software which produced numerous Napoleonic and other era wargames. The scenarios were always based on real battles and the orders-of-battle were very accurate. I know Andrew Bamford worked with him on the Peninsular War games.
He will be missed.

So Sad. My son and I had hours of fun with those early games, very educational too. Glad to see new games are still available. Paul
