Valmy and Jemapps 1792

Wargaming Scenario:
Valmy: 20 Sep 1792

by Paddy Griffith


Please note that these must be considered as `approximate' rather than 'authoritative', since the precise details are often missing from the historical record.

Starting Positions:

It is 7 am and very misty, with drizzle and a bitterly cold wind. Visibility is about 150 yards apart from intermittent breaks in the weather which sometimes allow a full view over the whole battlefield (for 5 or 6 on a D6 rolled each turn). Artillery fire is at one third normal accuracy unless one of these breaks occurs, or unless the range is under 150 yards. Battlefield intelligence may not be collected or transmitted to commanders, in a form that may be acted upon, unless a scout has been able to physically see what he's reporting (i.e. the Dumouriez player may actually know the true location of the Prussians, but he cannot act upon it until he first receives a valid report from the front line).

Kellermann's army is entirely concentrated around Dommartin la Planchette, on either side of the main road, north of the Auve stream and West of the Etang du Roi. He has already issued orders to his troops to cross the stream southwards to Dampierre le Chateau (over two narrow bridges), and they will start to move in this direction at 7 am, and will continue to do so until such time as Kellermann issues new orders (and even then, any orders he issues will be obeyed only for 3-6 on 1D6). Dumouriez is to his East, on the higher ground between Dommartin and Ste Menehould, with his army ready to move when they receive orders (which they will automatically obey). However there are two outposts further to the West: Deprez-Crassier's brigade of the Armee du Centre is at the mill above Valmy, and Stengel's force from the Armee des Ardennes is on the Yvron heights. Both are facing West with orders to hold their ground and give warning of any enemy action.

Outside the battle area Le Veneur's independent force from the Armee des Ardennes starts 10 km NE of the NE corner of the battlefield, potentially available to make a deep outflanking move against the Prussian left rear, but unable to move until he receives orders from Dumouriez. Even then, he will obey them on time only if he rolls 6 on a D6; one hour late for a 5; three hours later for a 4; and not at all for 1-3. If he does move, he will make three km per hour.

The Prussian vanguard enters the NW corner of the battle area at 7 am, heading SSE to La Lune. Its navigation depends on peasant guides and will err 45 degrees to the left for a roll of 1 on 1D6, or 45 degrees to the right for a 2. It is advancing in two parallel columns of platoons. Immediately behind it come the heads of the 1st Line on the left and the 2nd line on the right, each also advancing in columns of platoons, and facing in the same direction. Brunswick and the king accompany the lead battalion of the 1st Line.

The leading squadrons of Weimar's cavalry enter the battle area at the same time as the leading elements of the 1st and 2nd Lines, and located between the two. Unless Brunswick issues any orders to the contrary, the head of the vanguard will halt at La Lune (or wherever it has been led to!), with the two lines of the main body following on behind (although Weimar will probably overshoot and keep on going until he encounters some physical obstacle!). Then each platoon will turn to its left, to end up as two long lines facing East. Then it will stand and await further orders.

NOTE: Prussian losses in the real battle were 200 killed and wounded: The French lost 400.
