Gembloux Gap 1940

 More Dominion of the Blitzkrieg, this time the Low Countries in May 1940. This scenario is billed as the Battle of Gembloux Gap on 13/14 May 1940, but looking at the composition of forces, it bears more resemblance to the Battle of Hannut which took place two days earlier as 2nd and 3rd DLM covered the deployment of 1st Army and were engaged by 3rd and 4th Panzer Divisions. Anyway, historical account here:  https://en.wikipedia.org/wiki/Battle_of_Gembloux_(1940)

And here we are, Gembloux is the centre bottom of the map, Hannut at the mid top, the River Sambre is on the right and the Dyle on the left. The open ground between the two rivers being the 'gap'. It is a popular place for battles as Wavre is on the left, and Waterloo a few miles further west.

The pre-war Allied plan involved moving into Belgium and building a defence line along the Dyle river, the Wavre-Gembloux-Sambre line was the eastern extension of that. The 'Dyle Plan' absorbed almost the entire French mobile reserve, leading to Churchills lament later in the campaign Ou est le mass de manouvre?

Anyway, here are the baddies, 3rd and 4th Panzer Divisions, 20th Motorised Division and 35th Infantry Division of XVI Panzer Corps. Although both panzer divisions had numerous vehicles (over 300 tanks each in four battalions), these were not first rate divisions and they were mainly equipped with Pz I and Pz II as was 9th Panzer Division in the Netherlands. All these formations task was to attract the Allies attention and keep them pinned. The Germans lost around 150 tanks at Hannut but repaired two thirds of them.

In the front line we have two tank units (3rd Panzer, 4th Panzer) and an infantry unit (20th Mot). In reserve is another nameless tank unit, 35th Infantry Division and a unit of bombers. All these units are average.

The French have 2nd and 3rd Light Mechanised Divisions (DLM), somewhat battered after two days of fighting at Hannut, but equipped with a far higher proportion of gun armed tanks (Somuas and H39s) than the Germans and with thicker armour too. The French also lost around 150 tanks at Hannut but were forced to abandon most of them, so here the units are just rated as regular tank units. III Motorised Corps had the 1st Moroccan Division (DM) and 15th Motorised Infantry Division (15 DIM), both first rate formations.

So here we have 1 DM dug in and modelled as disciplined infantry with AT guns, in the centre 2nd DLM (tanks) and on the right 15 DIM, also disciplined infantry.

In reserve are 3rd DLM (tanks) and the Corps artillery - a regular artillery piece with two fire missions. I used a Chinellette carrier to represent the ammo state for the artillery.  The Somuas and H39s are all QRF as are the Pz I, while the Pz II are Peter Pig. 

Things kick off with Stukas inffectively attacking 2nd DLM in the centre, but 1 DM on the left managed to fluff it and are overrun by 3rd Panzer Division! The French artillery fired on the tanks needing a 3+ and missed, then the AT guns fired needing 5+ to hit and missed then finally the tanks hit on a 6. You can work out the odds. 

To add insult to injury the 3rd DLM in reserve failed to move leaving an open flank.

Fierce fighting in the centre as 2nd DLM was destroyed by Stukas, but their place was taken by 3rd DLM bravely driving through the bombs and forestalling 4th Panzer. 

3rd DLM kept going, supported by the French artillery and routed 4th Panzer. Ouch!

In the centre fresh panzer reserves moved up. Lack of French air power made this 'anything but a 1'. The dice decreed the German right would attack, and 20th Mot duly bounced off 15 DIM.

The dice decreed more fighting on the right and this time the Germans came out on top, rather against the odds.

With 3rd DLM committed, the French gunners suddenly found themselves firing over open sights. No reinforcement roll here as the Germans were using infantry.

3rd DLM and the new panzers suffered mutual annihilation, but the German still had more reserves to throw in and 35th Infantry Div took over in the centre.

The French gunners were assaulted by 20th Mot but easily repelled them. Reduced to just one unit however, it was all over for 1st Army. That was actually a pretty historical result as both sides suffered heavy but fairly similar armour losses and eventually the French were forced back.

Time for another run as these rules are pretty random and the Germans were very fortunate at times in that one.

This one opened in much the same way with an ineffective bombing attack on 2nd DLM, and  a French attack by 1 DM on the left. This time the odds told and 3rd Panzer was routed by the French AT guns, 35th Infantry moving up to take their place who could fight the French on equal terms (both needing 6 to hit!).

More ineffective bombing on 2nd DLM, but 20th Mot was routed by the 15 DIM on the right. Reserve panzers moved up to take their place.

The dice decreed combat on the left, and both sides managed to roll a 6. Mutual annihilation!

3rd DLM moved up into the gap easily as there was no German armour opposing them. All the Germans could do was commit the Luftwaffe to try and interdict the gap, which also precluded their offensive bombing operations.

The Germans attacked 15 DIM on the right, and the French fired their artillery in support and managing to throw a miserable 1. The attack failed in any case (the tanks now needed a 6 to hit the entrenched infantry).

3rd DLM advanced on the left...

And broke through the bombing! The German right flank was now in the air.

And it was over pretty quickly after that as 2nd and 3rd DLM crushed 4th Panzer between them. Which just goes to show the Germans don't have it all their own way in 1940.

That was a very enjoyable scenario, and as usual I enjoyed looking up historical stuff up about it. I ran a Hannut game a few years ago using NATO Brigade Commander but it strikes me as an obvious candidate for One Hour WW2.

I felt much more confident with the nuances of the Blitzkrieg rules, and I think I've got the hang of rolling for reserves to arrive. I may have made a few mistakes, but if I did, they didn't show and the narrative of both battles was very convincing. One thing this set does quite well is capture the knife edge which 'Blitzkrieg' style armoured operations work on, if it goes well it goes very well, but once the combined arms machine starts to unravel, it all goes horribly wrong very quickly. Air support is absolutely critical as without it, things devolve into a low odds slugging match.
