During the French turn a unit of French Hussars decided it was time to join the opposite flank as the French center was gone and their right flank was down to a wavering Conscript infantry and 2 Light Cavalry units. So they turned 90 degrees and rode off. Unfortunately there was a French gun battery directly ahead of them and since they had already wheeled 90 could not wheel any further to try and get around it.
Seeing a great opportunity my unit of Austrian infantry with artillery attached marched up and was able to get the back corner of the cavalry within 2 MU. Intention here was to blow it away during shooting next turn. On the other side of the French artillery unit was a unit of Dragoons, who were looking up the road at the French LOC and making a right wheel would put them on a course to get behind the French flank, which was still a threat and fairly intact. Off go the Dragoons who end up right beside and just behind the front of the French artillery unit. Thinking the guns would block the Hussars. Apparently not, and this is where the weirdness sets in.
French turn they declare a charge with the Hussars whose front is touching the side of the French battery, against the Dragoons who are just a few MM from the other side of the French battery. Fortunately I had lurking infantry about
Although I thought the guns would block the charge apparently not. Charges needing an interpenetration will move the blocking friends out of the way 
So the Guns magically move forward a full base depth. The guns were at a bit of an angle to the Hussars so their back corner was still in the way, NO problem say the French. We will Make the slight wheel and take your flank. Then I reminded him of the infantry within 2 MU of his back corner.
End result was the Hussars took 4 hits to their rear, went wavering and had to make an outcome move towards their rear table edge. Happy Austria.
Now the French shooting phase starts and the French measure from that magically moving battery to my unit of Conscripts that had spent the last 2 turns at med range (no attachment for those poor boys) Suddenly the guns are at close range
At this point I informed the French since their was no longer a charge and there was no unit to push them forward they should return to where they started, which he graciously did.First question: in a situation like this had the charge gone in and the guns stayed in place, would they no be shooting at short range, or should they have pushed back away from nearby enemy?
Second Question: The French start their charge 90 degrees to the Austrian Dragoons, with the center of their unit pretty much lined up with the line of my front and back bases, so center lines are almost even. If there had been no shooting, the French would still need to wheel to clear the back corner of the guns. French are 120mm wide, I am 90mm wide since its front facing side.
The restrictions on wheeling in a charge are:
You can't cross center lines, so if they were even and the French center moves off my center does that count as crossing?
You can only wheel if it brings more of the enemy to your front. In this case wheeling period does not change how much frontage of my unit he gains. Would this cancel the wheel?
So could this have been the Frenchies miraculous move in our game, getting to shoot at close range while not actually moving and getting a flank charge?? Glad for once I had planned that one out the way I did.
