Megagame Don’t Panic offside report

Last Saturday I was political control for the megagame Don’t Panic. As mentioned previously this is a what if megagame about the German Invasion of Britain in 1940. The scenario necessarily changes history to remove some of the most obvious reasons why the Germans didn’t ever try this during WW2.

Anyway my role was to keep an eye on the British war cabinet and ensure that they stayed suitably strategic and global while still providing input to the player teams at Command and Corps level. The game needs some player induced friction from the top, especially when Churchill has a wizard wheeze and send a Division Commander one of his famed ACTION THIS DAY notes.

The structure of the megagame was in two parts. From arrival until 1230 was a planning session simulating July and August 1940. Following that the German invasion lands in early September, and the game moves to 12 hour turns every 40 minutes or so.

Don’t Panic Political Game

The political game started pretty much on arrival for the players, before even the plenary briefing. I had a stack of laminated political event cards to throw in if the war cabinet looked less busy or was spending too much time in the details of the military game. I also had a panic track to keep score of how well the war was going for Britain and how the war cabinet were contributing to that. The panic track was on a 100 point scale and started at 50. Every 10 points the British got a modifier to their supply state depending on the direction of travel.

At the very start of the game I put some ground rules down for the war cabinet players.

  • There needed to be an official record of all decisions by the war cabinet
  • All decisions had to be by consensus, effectively giving everyone present a veto if they were uncomfortable with the direction
  • Collective responsibility applied to decisions, failure to abide by that would lose them political capital
  • Decisions that were unpopular or against advice required political capital to be spent (which was sometimes returned if the outcome was good)
  • Actions that were carried out by other players needed to be communicated by a war cabinet player to the appropriate person to make it happen

Political Discussion

There were some interesting discussions at Cabinet, (I have retained the minutes and will make them available over on Milmud). To start with there was a discussion about the Royal Family. Should they be dispersed or remain in the UK. It was decided that at the very least the King should be seen to remain until the last sensible moment. Other members, especially the two Princesses, would be kept away from likely invasion landing areas and removed from the country if things started to go badly.

The Royal Navy

The next major debate was on the Royal Navy. Sadly Admiral Pound seemed to be asleep for much of this, which would have been OK had it not been for the consequences following the decision to move most of the fleet from Scapa Flow to Portsmouth. The Cabinet Secretary made a number of interjections to the debate and attempted to put context on the importance of keeping the Kriegsmarine bottled up and the disastrous consequences should the Germans get capital ships in amongst the supply convoys. The politicians in the war cabinet were concerned about the fact that it would take the capital ships at least 24 hours to respond to an invasion across the Channel from Scapa Flow and they couldn’t be sure how well the RAF and army would be able to defend against seaborne assault without naval assistance.

As it turned out (and I listened in to the three way debate with the German Admiral Lutyens) the threat wasn’t as clear to the Germans as it looked to me. Lutyens waited before committing to action, and even then didn’t commit all his resources to breaking out into the Atlantic. Lutyens concern was, rightly for him, that the end result for the Kriegsmarine was likely to be loss of all vessels that they put in the Atlantic. What Lutyens either didn’t seem to realise was that this was potentially a game winning move for the Germans. His fleet unchecked in the Atlantic caused supply difficulties for the British. It also increased the panic track by 3 points every turn.

Once the German fleet was out it created all sorts of bother for the war cabinet. They debated moving Force H out Gibraltar, and more Cabinet Secretary intervention was required to ensure the war cabinet was properly advised. It was about that point that the Italians started their offensive in North Africa…

German Invasion

The invasion front about 12 hours after the initial landings, the blue counters on the beach are the German supplies.

The Germans invaded on a fairly narrow front, about 40km, in the Brighton to Portsmouth area. A planning failure (they didn’t follow the orders they’d been given) meant that they didn’t have enough transport units in the first wave, so they couldn’t move supplies inland. This limited the operating radius of the landed troops to about 8km from the beach. Also the Germans sent armour in the first wave, but couldn’t unload any of it without a port (which was clear in the briefings).

To help things further along the RAF got air superiority over the channel fairly rapidly, and unlike the Royal Navy, sank a significant proportion of the invasion fleet. The Royal Navy frankly didn’t know whether or not it was coming or going. The army reacted as fast as it could to the landings, but was hampered by a combination of shortage of supplies, rail capacity and their organic speed of movement. Mainly the army was a bit further East than the German landing spot. About this time the Royal Navy lost a battleship to a combination of mines and u-boats, this didn’t help panic levels even though the cabinet suppressed the news.

The panic track went into overdrive at this point, and the war cabinet got quite panicky. Their reaction helped things, although not as much as the RAF shooting down dozens of Luftwaffe and sinking about half of the German transport fleet. About two days into the invasion the front stabilised and the Germans largely became unable to land more troops or supplies. They also stopped making progress inland too. The Royal Navy lost a cruiser in the Channel too, damaging the two German Capital ships and driving them off to Brest.

All through this time I was also throwing political events at the war cabinet, making them worry about the Soviets, Japanese, Italians and the Americans, as well as domestic issues. Churchill spoke to President Roosevelt and Lord Halifax spoke to the Irish foreign minister, neither with any real success, although FDR was sympathetic.

Gradually the British Army started to get a grip of the situation (largely after Churchill personally gripped the senior officers). The RAF helped this with carefully targetted bombing of German Divisional HQs and supply dumps. In Portsmouth the Royal Marines held out although surrounded, aided by naval gunfire support over open sights. Even the Press (10 issues over the afternoon) finally became pro-British with the headline news from an anonymous German commander that their situation was hopeless.

Next week’s megagame Don’t Panic is an alternative history megagame about the German Invasion of Britain in 1940. It’s a popular what if and makes an interesting game for us British because the playing area is familiar to us from our everyday lives. At least it is familiar if you live in the South East. The megagame handbook has the village I live in centred in the combat example. German panzers occupy Redhill, the nearest town.

So could a German Invasion of Britain in 1940 have worked?

The answer is yes provided the Germans could have kept the Royal Navy and the RAF away from their invasion fleet and also managed to find enough suitable craft for moving an army across the channel. They also need to be able to sustain the landed army and reinforce it faster than the British can send reinforcements to fight them.

Personally I think that this is too much of a tall order for the Germans. They have no real appreciation of naval warfare. Nor do they have any joint planning staff. What allows the Allies to launch successful amphibious assaults later in the war is a combination of joint planning and lots of practice on a small scale before they tried bigger stuff. Even then Dieppe shows how hard it is to assault a lightly defended small port with armour.

The Kriegsmarine

The Kriegsmarine is smaller than the RN home fleet by an order of magnitude. Even if the German capital ships break into the Atlantic for commerce raiding the RN still has sufficient destroyer and lighter craft to wreak havoc in the channel.

The other major issue that the Kriegsmarine have is that they don’t have the tradition and corporate memory of the Royal Navy. So their skill level is confined to submarines and small to medium surface fighting vessels.

They’ve got no assault landing capability and no naval air. They also don’t have the same expansion capability the army had. So there isn’t the manpower available to them to suddenly crew loads of invasion barges. Those last need to be taken up from trade, which will have a negative impact on the German economy. So the Kriegsmarine doesn’t have the capacity to support a German invasion of Britiain in 1940.

The Luftwaffe

At best the Luftwaffe has parity with the RAF. However Britain is outbuilding the Germans in aircraft. As time passes the RAF grows in strength. Also lost RAF pilots tend to land in friendly territory and so get back in the air rapidly. Luftwaffe pilots tend to get lost in hostile space and become POWs.

The Luftwaffe is an asset in one way though. It exists to support the advance of the German Army. So if concentrated on that it can help the advance, however the liaison is in 1917 levels of planned support. It cannot be called off or amended once the planes are in the air. So only limited value in supporting a German invasion of Britiain in 1940.

That said, for the invasion to be successful the Luftwaffe needs air superiority over the invasion route and beaches. This is doable, but not guaranteed to be lasting.  It also needs to keep the RN at bay. I think the Luftwaffe vs RAF is the crucial battle. If the RAF win (and a draw counts as a win) then the Germans can’t invade Britain. If the Luftwaffe win then the Germans have a chance, but only a chance.

The Army

The German Army is good, experienced and tested in both Poland and the West. So it should outclass the British Army man for man on average.  The better British units will be better than the average Germans. The key issue though is numbers, and logistics. The British will have the best of both of these.

Conclusions

So if the Luftwaffe do an excellent job and keep the RAF and the Royal Navy at bay then the Kriegsmarine could put the German Army ashore. Once ashore the most likely outcome is that after hard fighting in the South East the Germans get defeated once additional British reinforcements arrive. The Germans will have a slower build up and their supply situation will be poorer than the British.

The hope for the Germans is for a collapse of civilian or political morale in the week after the German invasion.  Any more than a week and the entire British Army will be against them. British military successes are likely to restore faith.

This is where the megagame Don’t Panic will be exploring the what if of the German invasion. I’m really looking forward to it.

Operation Sealion: A Military Appreciation

The next megagame I’m going to is Don’t Panic a what if scenario on Operation Sealion, the planned German invasion of Britain in the autumn of 1940. I’m going to be the British Control. So no playing for me. However that doesn’t mean that I can’t look at how I would plan the Operation Sealion invasion myself.

Operation Sealion

Firstly we need to get into the nazi mindset. They’re essentially divide and conquer gamblers with no medium term view. They have an innate belief in their own superiority and on the inevitability of their eventual victory.

The other interesting thing is that the German General Staff see crossing the Channel as simply a large scale river crossing. To them it’s like crossing the Rhine, only a bit wider. This affects their thinking and probably explains why they didn’t ever attempt it. As they planned it, the obstacles just multiplied.

Fuhrer Directive 16

On 16th July 1940 Hitler issued Directive No. 16 On preparations for a landing operation against England. This set the initial conditions for planning Operation Sealion.

Since England, in spite of her hopeless military situation, shows no signs of being ready to come to an understanding, I have decided to prepare a landing operation against England and, if necessary, to carry it out.

The aim of this operation will be to eliminate the English homeland as a base for the prosecution of the war against Germany and, if necessary, to occupy it completely.

Situation

The German army has been victorious, sweeping all before it. All of continental Europe from Poland to the Pyrenees is under German control. Only Britain stands alone against Germany. The British army has been defeated in Europe and has left most of its first line equipment behind.

By mid August 1940 the panzer divisions will have been refitted, casualties either returned from hospital or been replaced. The luftwaffe is established in the French and Belgian airfields. The Kriegsmarine has assembled lots of barges ready for crossing the Channel.

In Britain the beach defences are being strengthened. However, the Briitsh Army is still short of transport and heavy equipment. The situation is so desperate that the British government has even called up old men and boys into a ‘Home Guard’. Weapons are so short that some of the Home Guard are armed with pikes.

Broadly the German invasion force can expect parity in numbers with the British in the invasion area. There is a qualitative advantage in terms of equipment and experience. The campaigns in Poland and the West have proved that beyond doubt. Operation Sealion is expected to follow the same pattern as the previous campaigns.

Mission

Hitler requires a speedy end to the war. German industry is short of manpower and the army needs to release skilled men soon. Operation Sealion is intended to bring the war to a speedy end.

Considerations for Operation Sealion

Broad vs Narrow Front

Normally military strategy suggests concentration of force. As an attacker you have a choice where you attack. A defender on the other hand has to spread out to cover all possible avenues of approach.

The British can be expected to rapidly deploy their remaining mobile reserve, including an armoured division, against any landing. This could tip the balance before strong enough German forces are ashore. The speed of response is likely to be slower if they cannot be sure where our schwerpunkt is located. Multiple landing points will aid this.

Ports

We need to capture a port as early as possible to enable unloading panzer forces. Once panzers are set free in England we can be assured of victory.

Both of these point to a strategy of attacking multiple small ports to ensure that at least one is captured rapidly.

Airfields

We also need forward airfields to help the Luftwaffe support ground forces. It will also enable air landing troops to be brought in. This will speed up the force build up and make it harder for the British to defeat us in detail before we can join up.

This leads to the selection of ports. RAF bases at Marston and Tangmere have recently been abandoned and are in close proximity to ports. Similarly Dover has two airfields in close proximity and the castle is a major threat to our use of the channel.

Causing Civilian Panic

Fleeing civilians are useful to the German success. They cause bottlenecks that stop the enemy bringing up reinforcements. They also adversely affect morale. This latter is important politically as well as militarily. We need the British Government to sue for peace. The faster this happens the better.

Effective ways of reducing civilian morale are:

  • airborne troops behind the main lines (even if only rumoured);
  • tank breakthroughs, especially if accompanied with pictures at iconic places for the newspapers and cinema news reels;
  • sinking of supply ships so that rationing is tightened;
  • terror bombing of cities, especially London and other industrial centres.

Conclusion

Operation Sealion requires a rapid buildup with simultaneous action at sea and in the air to split or slow the British response is required to give time for a foothold to be established in England. This will maximise political pressure and ensure military victory.

General Outline

Operation Sealion’s broad strategic goals must be to get a foothold, rapidly expand it and encourage the political opposition in the UK. Ways to do this are

  • surge the Kriegsmarine into the Atlantic for commerce raiding (apart from the bits directly needed for supporting the invasion)
  • use a u-boat screen to stop the RN getting in amongst the invasion fleet.
  • select four small ports across the Kent and Sussex coast for direct seaborne assault supported from the air. Put a battalion of paras on the closest airfield to the selected beaches
  • reinforce success with air landed troops on the captured airfields and tanks into the captured ports
  • transfer luftwaffe units to the captured airfields as rapidly as possible to increase loiter time and range
  • collect up the paras as soon as possible for a second drop on London or wherever intelligence suggests Churchill or the Royal Family are hiding out.
