The Prussians in total had three brigades of infantry and one of cavalry, totalling 15 btns, 2 regts and 8 batteries. Commanders were rated either 8 or 9. The French had three brigades of infantry, and a brigade of cavalry, 12 btns, 3 regts, 4 batteries and 2 mitrailleuse. Commanders were mainly rated 7 with a couple of 8's Sorry for being so vague but in the tidying up that followed the game I misplaced the orders of battle for both sides.
It seems a long time ago now and my notes have been put away somewhere safe but here is what I think I remember happened. So, cutting a long storey short, the Prussian (allied N German) blocking force managed to keep the French pinned in the village while the main body proceeded to engage the rest of the French who were then unable to extricate themselves from the fight. Two battalions made it across the river but soon found themselves disordered, fired on from the front and rear and charged (unsuccessfully) by cavalry. They ended up being stuck in or just across the river, pinned under artillery fire and threatened by a further cavalry charge. Elsewhere, the Prussian artillery was effective at knocking out their French counterparts and the mitrailleuse batteries, and the French cavalry, i.e. both of my lovely Chasseur a Cheval regiments, was equally effective at dashing itself to ruin in futile charges against the oncoming Prussian infantry, although to be fair they did achieve their objective of forcing back one battalion and holding up the Prussian advance for a couple of moves, long enough perhaps for some of the French to extricate themselves.
In the end we decided that the French would be unlikely to get away in any significant strength as the blocking force, despite being second rate troops, was just about holding its own, and the rest of the French were likely to be overwhelmed by vastly superior number of Prussian infantry and artillery.
Poor command rolls by the French (me) meant that I was unable to take advantage of the first two or three moves before the bulk of the Prussians made their presence felt to galvanise the main body into some sort of order and across the river where superior numbers and firepower would have driven the blocking force away. Anyway, that was the plan, indeed that was the premiss behind the scenario.
Again, the amended rules for disorder and break tests, taken from Hail Caesar, worked really well.
