I re-played this game out a couple of weeks ago, but have now just got a chance to type up a report. There are some changes in the OB, the reinforcement entry and the scenario specific rules. I will save more for my comments at the end.
Order of Battle:
The OB I am using is pretty accurate, and covers the first 3-4 hours of the action. I have left out the other brigade (Tissot) in Foy's 9th Division and I have not included Bachelu's 5th Division (For the sticklers on accuracy: There is significant documentary evidence that only one of Foy's brigades was engaged in the fighting, most likely Tissot's, but figure availability made me use Jamin's Brigade. I have also recently found out that the 2e légere were probably transferred to Bachleu's Division on June 10 and the 3e ligne were substituted into the Bauduin's Brigade). The British have two entrenched artillery units on the ridge overlooking the eastern approaches to the complex. They are not movable, but of course can prolong. I have used standard Lasalle ratings for all the French, I do not believe the 1,2,4e légère can be rated elite troops. I increased the SK value for the Nassau from the AB list. I have made the light companies of the allies irregular, I believe of course they would have fought as such, and the 1/2e légère are also irregular. They represent all the skirmishers sent forward in Baudin's brigade. The French sub-commander rating have been diced for, I have made MacDonnell a superior commander and Saltoun a good tactician and vigorous commander. Two engineering groups have been attached to the French. Soye's Brigade enters in Attack Column at the southwest corner, while Jamin's Brigade enters in Attack Column at the south east corner of the terrain. The 2/Coldstream and the 2/3rd Guards enter in March Column at the north corner of the terrain. Turn entry for the reinforcements is designed for this out of proportion complex.
The terrain is 7x5ft and the central part is dominated by the Hovels 15mm model. I really can not use the concept of Lasalle BUA (1 BUA equals 3 BW) as laid out in the rule book because of the size of the model. Because of this, I felt that it was reasonable that the maximum number of models that could occupy the walled Hougoumont complex at one time was essentially no more than a battalion (up to a 1000 men, so a 6 base unit is reasonable), that 2 battalions could occupy the formal gardens and that no more than a French brigade (6 battalions) could attack at one time. There is a zone of control (area which is barred to non attacking units) of 6 BW and that no more then 3 battalions can be in the ZOC on any one side of the Building-Formal Garden complex. The complex and the walls around the formal garden are impassable aside from the hedge row at the northern part of the formal garden.The gates and the walls can be destroyed as noted in the scenario specific rules. The walls are all hard cover. Movement within the complex and the formal garden is unrestricted and all units are in the complex are in the town deployed formation, but in the garden are regular formation. The 2 internal gates within the complex are not impediments. Movement out of the complex and through outer gates is in march formation. Woods around the complex are defined as rough terrain and soft cover. If using a smaller model, as defined by the Lasalle rulebook the building complex should be 1 BUA and the formal gardens 2 BUA. I would then half the turn entry for reinforcements ie. bring Soye's Brigade and 2nd Coldstream Guards in at Turn 8 rather then turn 16.
