I recently completed reading John Terraine's excellent history of the RAF in WW2, The Right of the Line, and was fascinated by the strategic focus of the senior leaders of the RAF in the inter war years on the capability of air power to decide a war alone. Attempts were made during the war to implement these ideas, but the agenda set by the axis powers meant the RAF was never free to fully implement them. So what better place than HOI3 to test an alternate universe?

The scenario contends that in 1936 the RAF achieved the patronage of a significant number of politicians and Whitehall mandarins, and strategic air power became the basis for the defence of the realm. Never again would the Empire's flower of youth be sacriificed in a continental meat grinder! Air and sea power would safeguard the home isles, but what of the continental allies - does this new policy abandon them to confront fascism alone? Could the UK's new strategy protect France?

PREPARATION
The strategy followed was broadly thus:
* everything aviation related was top priority for research and procurement.
* the heavy bomber force consisted of 8 fully upgraded units by Sep'39 , with a further 6 under construction due to be completed in the second half of '40.
* CAS, TAC, INT, FTR and NAV were also built.
* additional airfields, radar and AA constructed throughout SE England.
* the navy was second priority, with the carrier force expanded and cruisers and escorts added to the fleet. No emphasis on bb's or BC's apart from AA.
* the army was a distant poor relation. Only infantry equipment and doctrines were researched, everything else was left pre war. The only job the army would have would be to safeguard the Middle East, East Africa, Malaya and India.


WAR
At the outbreak of war the entire peacetime army was shipped from the UK to Egypt to prepare for Italy's entry. Likewise, the entire Army of India was shipped to East Africa. Garrison units were built starting with the outbreak of war to safeguard against any random German attempt to invade the UK.

The RAF was deployed to France, with the exception the strategic bombers which remained in England.

The RN immediately launched port strikes on the German fleet in its home bases. This crippled the German Navy so that it did not feature as a threat for the first 18 mths of the war ( Norway was never seriously threatened as a result).

In Feb'40 the RAF started attacking all the Luftwaffe bases in western Germany. TAC's mated with multi role FTR's hit the airfields in reach, while those out of range were bombed by the STR's at night. By the end of Feb the Luftwaffe had disappeared from the skies - grounded on bases pounded to rubble.

This then allowed the RAF to create a one province wide infrastructure "wasteland" stretching from Emden to the Maginot line. By bombing every provinces infrastructure to less than 5% along this corridor the movement of supplies across this barrier was reduced to a trickle.

Germany then invaded the Low Countries ....... Would the thin blue line hold?

THE OUTCOME

All of the German units cross the border with 30 days supplies and fuel. Once this is expended they need to rely on the logistics system to keep going.

Consequently the Netherlands and Belgium were steam rolled, and the German juggernaut made it a far as the provinces adjacent to Paris, but there they ran out of fuel and supplies. The AI controlled French army was then able to hold them, and eventually in late '40 was able to start to push the starved units back.

As the Maginot line fell, the infrastructure barrier was extended. Eventually it stretched all the way from Emden to Switzerland - 16 provinces which needed to be constantly shuttle bombed to prevent infrastructure recovering.

When the Italians invaded the three provinces west of Milan were attacked by STR's from Malta. The Italians made it as far as Bordeux before they ran out of supplies.

By the middle of '41 the French were back in Brussels and were holding a line roughly running south from there, but the Italians had been pushed all the way back to Milan.

All this without a single UK ground unit committed to the continent!

By mid 41 the AI seems to have woken up to the need to contest the skies and it's getting harder to maintain the barrier. Carriers in the North Sea are providing air superiority missions over 12 of the 16 provinces but it's getting harder.

Ok, so here is a screenshot of the front on the 1st August 1941 - France is holding and is starting to counter attack, particularly down south. I've violated my "no boots on the ground rule" for the British Army to take advantage of an opportunity too good to pass up. After clearing the Italians out of Nth Africa and occupying Sardinia, the Desert Army landed in the Italian rear and occupied Marseilles - the starved and immobile German and Italian units in SW France are now encircled. Mr Churchill's brilliant and flexible use of maritime power has removed the stain of Gallipoli!

The next image below shows operations over the infrastructure barrier - a typical day on the air front. CAGS are conducting air superiority missions over the length of the corridor, while the last four provinces, Strasbourg to Mulhouse, are covered by MR FTR's from Paris. The heavy bombers operate in daylight and are occasionally intercepted, but generally bomb unmolested. The Luftwaffe units located to the west of the barrier tend to be very short on fuel. Note also energetic RAF support for the French army.

And one "cheating" screen shot as the German player to demonstrate the impact this use of airpower is having on the Axis forces. The image below is the infrastructure display - the corridor is clearly displayed as the dark line running North - South. Note the number of red out of supply units located west of this line. The Italian version can also be seen just west of Milan.

Some observations:

  • The AI doesn't appear to try and get around the barrier by setting up supply convoys - though if attempted the Royal Navy would make short work of them - plus bombing the import ports would shut down the flow anyway.
  • The Germans seem more impacted than the Italians - I think because more motorisation and armour equals more supplies needed.
  • Note you never shut down the supplies completely - a trickle is always getting through which seems to mean about a third of the German units are supplied at any given time.

So far this strategy is preserving France, but I'm not sure yet how it can be turned into a war winning play. At some point the barrier will need to be moved further east to enable an advance - but this will depend on improving the ranges of fighters to ensure the heavies don't get carved up.

What I can think of to bring about a decisive victory is to concentrate your tactical airpower along a small front to punch a hole in the German lines that your land troops can lead the French through.
 
Very interesting. It just gave me some thoughts about a rocket assisted Barbarossa. Several zero infra pockets then surrounded on the outside while the Luftwaffe destroys the divisions inside. Damn, now I may have to start another game.
 
Another half year of progress to report. It's 1st March '42 and the French Army is on the offensive. Things are looking good, but France had a near death experience in Dec'41 - see image below:

PAAAFrDec41.jpg


I had set up the logistical bombing campaign largely on autopilot, with each bomber group of 2 units assigned 4 provinces to attack. Likewise groups of three fighters were also assigned their own four province sector to own, and this seemed to be working. Unnoticed by me though the AI was not distributing the attacks evenly and 4 of the 16 provinces were able to recover infrastructure to about 20%, allowing enough supplies through for the Wehrmacht to launch an offensive. As you can see above it took them to the gates of Paris and deep into the interior, but once the gaps in the logistics barrier were plugged it didn't take them long to run out of steam. Note the very limited numbers of German units able to advance.

Things are not looking good for the Italians. A 12 division pocket is about to be eliminated at Torino and the line is looking sick.

By March '42 however things are looking much more favourable - see below:

PAAAFrMar42.jpg


Note the big cluster of German units in the Ardennes - air strikes reveal them to be all out of supply. If the French Army can overrun the bulk of the German army we might have a war winning solution on the cards. More to follow.......

Well thats an interesting and unorthodox idea, I'm curious to see how this continues.
 
Won't you run into a problem wenn the french troops reach your "infrastructure wasteland" line?
I imagine you need to push it to the east. How about an Hamburg-München line?
By the way, who is in team allies?

Here's the current Allied list - only Yemen missing off the bottom.

I've been concerned about how things will go once they reach the barrier - any German units on the other side will be full strength and capable of thrashing the french like they normally do, so I think the key to victory will be to try and overrun the German units before they retreat across the barrier. A human player would see what's happening and strategic move everything now - but the AI won't, so there's a real chance they'll get defeated in battle (most are at org 0), then overrun while retreating. If this happens the French should cross the barrier and have a relatively free run. Once you stop bombing the barrier it normally only takes about two weeks of recovery for sufficient supplies to start flowing again to support a smaller army like the French (I've already crossed the Italian barrier in the south).

The nightmare scenario will be the french charging across the barrier - running into a respectable German force and getting badly thrashed - the Germans chase them back across the barrier and there isn't enough of a French Army left to contain them - French manpower is 0 so what you see on the screen is what's left.

The barrier does take a while to build then start functioning - once the barrier is built units have the 30 days of supplies and fuel they carry with them, so you can expect the attack to slow once the barrier has been operating for about 4-6 weeks. To weaken them enough for an easy counter-attack - you're talking about 2-3 months. So re-establishing the barrier to the East is feasible but the transition has to be planned to be effective.

A Soviet attack on Germany in the next few months wouldn't hurt........

Japan remains neutral.
 
Another 3 months and the French Army continues to creep forward, but the front has been static now for the last 2 months. The Italians have been conquered and a new front is pushing into Austria. From this point on wards the southern portion of the bomb line is being moved forward to run from Konstanz to Stuttgart to Kaiserslautern. Sort of like a creeping barrage on a grand scale. Current front below:

I think he is giving the orders 1 province at a time.
 
I've noticed that I usually run into issues when selecting 2+ provinces to be bombed - feels like only one ever really gets hit. Are you seeing it distribute more than that?

I have noticed the same - but it seems patchy. In some areas it seems to work well, others less so. I had set up 4 bombing zones each of 4 provinces, using the conical area selection tool to define a straight line. Of the 4 zones, two of them were covered evenly, but in the other 2 only half the provinces were being hit. I noticed that the unbombed provinces were adjacent, so I broke the 4 provinces zones down to two and assigned a separate unit to it and that seemed to work.
 
I think he is giving the orders 1 province at a time.

Initially I assigned them manually (particularly when I didn't have enough units to bomb the whole line continuously), and assigned the escorts manually as well. It does make for a bit of a laborious game in the beginning :(

But once it became a maintenance job and I had enough air units I set it up as described above.
 
Another three month update - 1st October '42 and things are looking decidedly sticky for Germany. The French have crossed the bomb line and have linked up with the attack from Italy, and have occupied half the Ruhr in the north. The RAF bomb line has been moved east and now runs Kiel to Frankfurt. Will the boys be home for Christmas ? I'm now considering whether to abandon the logistics attacks and throw all 22 heavy bombers on strategic missions to wreck German production.

PAAAFrOct42.jpg


He who lives by the sword..... Had a nasty experience with the troops in Austria running out of supply. When the southern French front linked with the troops in Austria north of Switzerland, the supply line, which previously had run south of Switzerland and into Austria, was switched to the shortest direct line which were the provinces just north of Switzerland. This meant they ran over the bomb line ( 2 actually), causing my troops in Austria to run out of supplies. It took about 2 mths for supply to be regained, during which the Germans were able to push back. Even though alternate routes were available, it doesn't appear the AI takes into account damaged infrastructure when deciding the supply route.

How is it going on the aerian front? Is Germany putting up some resistance to your bombings?
Nice AAR btw.

Most of the Luftwaffe was based on captured airfields located west of the bomb line, so they have spent most of the war out of fuel. I made sure the bombers have had some form of fighter support throughout so when air battles did occur the damage usually went to the escorts. This strategy is fairly fragile - it doesn't take too much infrastructure recovery for a decent amount of supplies to start flowing and the German army is suddenly off the leash. Losing a bomber or getting a few savaged could easily result in the whole thing falling apart.

Thanks re: the AAR. I've been playing the various forms of HOI for most of the last 10 yrs but this is the first time I've posted on this forum.

Of course you realize that that means you could just bomb a circle around Berlin and the whole wermacht would go out of supply. I truly hate the capitol centric supply system.
