An attempt at refighting Wittstock 1636 using my Sun King 1670s figures, with the French as the Swedes-Germans and the Allies as the Imperials-Saxons. My regular opponent, Steve, took the Allied side, I took the French side. The table is 6' by 4', the terrain reduced to the very basics of the 1636 battle and with the Allied army deployed first, the French then being positioned, but with them dicing for their reinforcements. The rules are my own; the small dice by the units represent "Fatigue Points", basically "combat wear and tear"  - not very photogenic, I know, but quicker than writing them all down and keeping track on paper! The cavalry action on the steep hill was fast and furious, with the French eventually prevailing, as they did on the other side of the field, but the opposing infantry did not come to blows by the time the game had to end. Here are some photos of the engagement.

The Allied camp - figures, I think, are by Colonel Bill.

The Allied dragoon regiment in the woods - completely forgotten by Steve for the entire game!

The Allies' fieldworks - the artillery could not move, lacking teams and limbers, these having gone to the rear, i.e. the camp.

The French deploy onto the battlefield - right wing in front, centre behind; their left wing and reserve were reinforcements whose arrival was dependent on the result of regular dice rolls.

Regiment Douglas.

Regiment Anjou.

The Allied left wing lined up in the valley between the plateau and steep hill - cuirassiers and light horse units; the cuirassiers are double squadrons, large and hard to beat!

The Dutch Regiment Reede.

The Allied right wing cavalry - light horse and cuirassiers units.

Allied foot - Ingen-Nielant and Münster Regiments.

French cavalry on the steep hill; the latter counted as severe ground so units accumulated "Fatigue Points" just moving over it.

The Allied left wing moves to engage the French force.

Hasty redeployment by the Allies on the plateau.

The Spanish Alcantares Regiment.

The French reserve arrived on the battlefield pretty promptly and was soon moving up behind the right wing and centre troops.

The French ignored the Allied camp and concentrated on defeating the Allies' troops first.

The French have cleared the steep hill of their cavalry opponents, but the line of foot was too intimidating to attack!

The Brandenburgers have formed Stand of Pikes in the lower part of the picture, the best all-round defence against cavalry, whereas the Regiment Münster has remained in line.

...but with the plateau still held by the Allies.
