I had been wondering how some of the scenarios from Charles Grant's Scenarios for Wargamers book would convert to Sharp Practice with its random unite arrival/activation so decided to try one of his Tabletop Teasers that were printed in Battle For Wargamers (and later Military Modelling) in the late seventies, indeed I picked the first 'teaser' published in the February 1978 of Battle - The Bride Demolition.
The scenario has Red Force attempting to destroy a key bridge before the recently arrived Blue Force attempts to capture it. To add some 'fog of war' Grant had a random generation/arrival of the Blue Force.
I decided that the existing Sharp Practice activation system would largely suffice for this, though I advised Phil that his French had to capture the bridge from a small Spanish garrison before a pursuing British force smashed into his rear. Each turn I rolled a D6 to "see if the British had arrived behind the French", in reality this cumulative roll was to see if the Spanish engineers (who the French thought were just peasants) had managed to mine the bridge!
Well that was a lot of fun! I wasn't sure how well a 43 year old scenario would translate to Sharp Practice, but overall it seemed to work very well with the battle ending extremely closely from a Force Morale point of view (Andy ended on just 1) and the bridge blowing up. A couple of luckier dice rolls and more favourable leader activations and this could well have seen the French victorious...
