Here is the adaptation of a Frederick's War scenario on vassal which details the dispositions for the Battle of Blenheim. It allowed me to set out my mounted Risk 18th Century figures to represent the four participating armies of the British-Austrian coalition and the Franco-Bavarian Army.
I adapted my core Battle Cry rules with a few period variants, the most significant was simulating Platoon Fire with the ability of the any British infantry unit to re-roll one miss. This did give their infantry an edge which I felt reflected reality nicely. Their cavalry were also classed as Elite which meant they could ignore one flag. This was to reflect their training to charge and dispense with firepower tactics.
A concerted assault across the bridges and French collapse mirrored the historical outcome.
