Another interesting looking Dominion of the Blitzkrieg scenario. This one covers Guderians Panzer Korps assaulting Sedan after its famous march through the 'impassable' Ardennes which rather took the French by surprise. This scenario includes armoured units and attack aircraft, so is more likely to generate the type of 'breakthrough' battles typical of the early war period.
The general setup, this is roughly 18" x 18". The Meuse is in the middle, with Sedan in the large river bend. There are heights to the south overlooking the various river crossings, and to the north is the edge of the hilly and heavily wooded Ardennes.
The French. I must say for 'surprised' troops there are an awful lot of them! Up front we have three Regiments of the reserve 55th Division in bunkers and entrenchments along the Meuse. In support are the divisional artillery. All the 55th Div units are rated as 'unreliable', and that also restricts the artillery to a single fire mission. The infantry units are all dug in though, so if they stand, they will be hard to defeat.
We also have a Regiment from 71st Division in reserve (historically they conducted a counterattack at Le Haut du Wastia, which I've previously gamed using One Hour WW2). Finally we have the Char Bs of 2nd DCR, which historically were committed at Stonne, and which I've gamed already using NBC WW2.
Armoured units in these rules generally aren't that great individually - they fight as well as infantry (basic 5+ to hit) but do get to fight first, get a bonus for outflanking, and also have a chance to disrupt the movement of enemy reserves, increased by the presence of air support. The French tanks are heavily armoured though so get a defensive (D) bonus. Both they and the 71st will have to weather the storm of Luftwaffe bombs to get there though.
The mighty panzers, representing 1st, 2nd and 10th Panzer divisions, although the Germans have four actual panzer units in the scenario (one is in reserve). Assume they are the three divisions and some sort of Corps reserve.
I've given each of these units three stands as they are divisions, not regiments, and 1st Panzer in the centre has a Pz IV and Sdkfz 251 as it is rated Elite. At the time it was one of the few units to have armoured halftracks, and it had a higher proportion of medium tanks than the other divisions which were mainly equipped with Panzer IIs.
Finally we have that huge He 111, representing the the 850 Stukas and medium Bombers of Luftflotte 2. An elite bomber unit, which is genuinely scary, a base to hit of 3+ AND it interdicts enemy reserve movement. Ouch.
Famously this engagement had been extensively wargamed by the Germans beforehand, and the operations orders issued were just the ones from the wargame with the dates changed. They are reproduced in Guderians 'Panzer Leader'.
A bit more of a worms eye view. I should probably have the 71st up on the heights and the Char Bs in the valley, but hey ho. These are all from my early war collection which have featured numerous times. The German tanks are all Peter Pig while the Char Bs are QRF. The French artillery piece is actually a 1/76th scale model of a 47mm gun which I've converted into a 1/100th scale 105mm.
The action opens with a bombing raid on Sedan - in the first turn the attacker can choose whether to bomb or attack with a ground unit. I assumed (erroneously) that you also got to attack in the sector bombed. In any case, it was ineffective and 1st Panzer was repulsed.
At some point the French have fired their artillery (the puff of smoke), but it obviously hasn't done any good. The Germans attack with air support on the left and the French run away. 10th Panzer have their bridgehead. The Char Bs try to fill the gap, but need a 4+ to move under air attack and fail.
This flank is now open, if the Germans make an outflanking attack from it, the French can roll to plug the gap again. The Germans can even attack French reserve units if there are none in the front line. That is very clever, and a nice way to represent an armoured breakthrough,
The French response is muted, the Sedan garrison attacks but the fighting is indecisive (they had to pick the most advantageous sector, and that is it).
The Germans attempt a crossing with 2nd Panzer, but it is repulsed by the defenders despite the air support. I got this wrong as the attack should have ended with the (unsuccessful) bomber attack. It does actually say that in the rules, but you need to read them carefully,
The German reserves move up to plug the gap. The French don't have any bombers, and none of their tanks are opposing them, so this is automatic.
The reserves promptly vanish in anothe failed river assault.
And now the Germans are forced to commit their bombers to holding the line - imagine a series of interdiction raids. This precludes the bombers from conducting any more concentrated attacks, and is similar to gunners suddenly finding themselves holding the line.
10th Panzer exploits its bridgehead to outflank and destroy the Sedan garrison. That gives the French a chance to move up reinforcements.
I got this wrong too. I assumed the only reserve penalty was because the French were facing German armour in each sector now the bombers were 'holding the line' so to speak, so success on a 2+. In fact if a side starts with reserve bombers, the penalty applies for the whole game, so it should have been 4+.
Anyway, 2nd DCR moved up to block 10th Panzer, while the 71st moved into Sedan opposite 1st Panzer.
1st Panzer promptly crossed the Meuse and routed the 71st! The French gunners now found themselves in the front line as they made their reserve roll.
Sadly for the French, they rolled 'activate centre' - the unreliable gunners ran away and 1st Panzer occupied the heights.
The Germans then got to choose a sector and 1st Panzer outflanked the last Regiment of the 55th on the Meuse, routing them. 2nd DCR counterattacked 10th Panzer but the action was indecisive. Reduced to one unit , a French defeat. Which of course was the historical result, but a hard fought battle nonetheless.
I was conscious that I had made some mistakes so re-read the rules carefully a few times. There is also a vey helpful example of play which funnily enough covers the Sedan scenario.
Having improved my understanding, time to go again.
The Germans open with a bombing raid on Sedan, which routs the defenders (they failed their reliability roll). Combat then ends, but effectively 1st Panzer now has a bridgehead over the Meuse. I've pushed an infantry stand over the river.
The French reinforcements fail to move up (needing a 4+ in the face of tanks supported by bombers).
There is an indecisive action in the right as the 55th engage 2nd Panzer, but at least the French stand.
1st Panzer then exploits the breakthrough with a flank attack on the left which routs the defenders along the river bank. You can either make a bomber attack OR a conventional attack. This attack allows the French to roll for reserves again, and the 71st move up to seal the breach. 2nd DCR fails to block 10th Panzer though, who also now have a bridgehead.
More indecisive fighting on the right between the 55th and 2nd Panzer.
Now the Germans ineffectively bomb 2nd DCR, while 10th Panzer makes an outflanking attack on the 71st. The French commit their artillery support, but the fighting is indecisive.
2nd DCR does however make its reinforcement roll and braves the German bombers to block 10th Panzer.
2nd Panzer is routed on the right, and reserves move up to take their place.
1st Panzer breaks out of Sedan supported by bombers, and the 71st flee. The brave French gunners of the 55th Division however managed to manouvre into place to block the panzers.
The French then manged to rout 2nd Panzer on the right (again).
Which leaves the Luftwaffe to hold the line. The Char Bs of 2nd DCR rumble into action and finish off 10th Panzer. 1st Panzer suddenly looks rather isolated as there are no more German reserves.
1st Panzer tries to outflank 2nd DCR but the move fails.
In turn, 2nd DCR flanks 1st Panzer and wipes it out. Guderian is flung back across the Meuse!
Well that was a turn up. What an interesting scenario, certainly excellent as a learning framework for the rules, probably more so than the Narvik one I originally picked. That was a great game, and what a clever and subtle development of the rules, although obviously a bit too subtle for my ageing brain cells! There are a couple more France 1940 scenarios I'd like to try out, which both feature more tank battles, so watch this space.
