The Duke's cavalry soon had the Markgraf's advance forces under pressure. At least the heavy regiment did - the light cav rgt twice refused orders to charge! The infantry - shot up by artillery just before the charge - didn't enjoy the experience and were soon in flight.
In time, a zig-zag of saps reached out to the town walls...
At this point we had a chat about what would happen next. It was agreed that the Duke's forces probably lacked the time to reduce the keep and would instead content themselves with slighting the town's walls and carrying off or spiking the guns.
A most entertaining day of gaming. Thanks to all the players and in particular to Pete and Russell for the use of their photos.
