The British grenadier battalion attacks the rail fence, unsucessfully:
The battle was a victory for the British and a slightly more cautious approach resulted in fewer casualties than in the real battle. Nevertheless the British light infantry battalion suffered around 25% casualties before routing and the more stoic grenadiers lost over 40% but held on to the bitter end.
The rules have evolved further. I'm now using simplified versions of the shooting and melee secions of British Grenadier! together with my own command/morale system. The game flowed well. It took just over an hour of "game time" - 14 turns running from 15:45 until 16:55, with play starting at about 10:00 "real time" and all being over by 14:30 including time for chatting, refreshments and occasional breaks.
