The game was the Battle of Lützen in 1813 using the second edition of the Shako rules.
I had command of Ney's troops in the centre of the table and was engaged by the allied troops from the first turn. I managed to hold them up a little (although my dice rolling was particularly bad!) but their numbers forced me to fall back before our reinforcements arrived.
It was a hard fought and bloody engagement. We failed to replicate Napoleon's performance historically though.
Here are a few photos from the day, apologies for the poor quality as I only had my phone with me:
