Yes, yes, I know that few things like the British Baltic Plan (a British naval incursion in the Baltic Sea during World War One) and Operation Sealion (German invasion of England in World War Two) are considered ASB by almost all alternative historians.
If you want to read and discuss a serious effort to describe a non-ASBish alternative scenario about a British Baltic Plan accomplished, then you are welcome!

A little background

British Baltic Plan was conceived in the end of 1907 by admiral Sir John Fisher, who became First Lord of the Sea immediately after the beginning of the World War One. In 1907 Germany appeared for the first time to British eyes as a potential enemy because of the first accomplishment of its huge new naval program. A naval war between the two European powers appeared possible and British Admiralty had to make a plan to win the war. The imaginative admiral Fisher conceived a “knock-out plan” aimed at a quick defeat of Germany: a landing in Pomerania (Eastern Germany) after a massive British naval incursion in the Baltic Sea, through the Danish Belts and/or the Sound (between Sweden and Denmark). In 1907 many weapons of the XX Century had already to be tested: there was few or no experience at all with torpedoes, mines, new long range guns, submarines and airplanes. The original Baltic Plan was a typical XIX Century plan, an incursion of surface vessels in closed waters. The experience of 1914 warfare changed little those assumptions. During the battles of Heligoland, Coronel, Falkland, new weapons (mines, submarines, airplanes) proved less effective than expected (Heligoland) or were not used by both parties (Coronel and Falkland, open sea battles fought by cruisers). Thus the idea of a new Baltic Plan emerged again in Fisher’s mind in the end of 1914 as a method to outmaneuver the stalemate in the Western Front. A new class of fast battlecruisers (Glorious class) and a new fleet of nearly 600 transports and escort vessels would have forced the Belts and supported a Russian landing in Pomerania. British would have provided the naval firepower and sea dominance. Russians would have provided bases closer to the target and all the manpower. The plan was discussed for months. Fisher supported it, Churchill supported it only in principle, Navy secretary Oliver didn’t want it, the more prudent admiral Jellicoe feared it, the foreign minister Grey didn’t supported it for diplomatic reasons (Denmark and Sweden could have joined Germany), until a decision was taken: give the priority to the assault of the Dardanelles, against Turkey. Fisher resigned after the first failures in the Dardanelles campaign. After Dardanelles the British Admiralty became more and more aware of the mines and torpedoes. Then the Baltic Project was archived, but remains in general Royal Navy strategic concept. An incursion in the Baltic was considered as a third step in a three phases strategy (as Churchill wrote in his “The World Crisis 1911-1918”):
1. Clearance of the outer seas
2. The blocking of the German High Seas Fleet
3. Entry in the Baltic
In 1914 British forces had already accomplished their first mission, but they never accomplished the second. They never achieved a complete superiority over the High Seas Fleet until the surrender of Germany. Thus the Admiralty never took into consideration the accomplishment of the third phase of its strategy in OTL.

Two possible PODs

There were at least two possibilities for a British forcing of the Baltic, no possibilities at all for the accomplishment of the original Baltic Plan of 1907.
While a landing in Pomerania was always nearly impossible (support lines too long, German coastal defenses too strong, sub-water weapons too dangerous for a prolonged operation) an all-naval operation was feasible. Light ships could reach the Baltic in 12 hours, be supplied at sea, engage a battle and the be supplied in Russian naval bases. Capital ships didn’t need to be supplied at sea, they could reach the Baltic, fight a battle and be supplied in Russian naval bases. For an eventual second phase of the operation, the Russian Baltic Fleet could have provided support.

I found at least two opportunities for a British incursion in the Baltic.
The first and easier to spot was in June 1916: if the British won a decisive naval victory at Jutland, they could have achieved a decisive naval superiority in the North Sea, the pre-condition for the entry in the Baltic. But in OTL the British never achieved a complete victory (or a victory at all), then they couldn’t force the Belts, fearing a new HSF sortie in North Sea, behind their lines. The possibility of a sudden British entry in the Baltic was clear and present in Russian’s mind on June 1st, when false reports of a British decisive victory against the Germans at Jutland induced the Russian Naval Command to ready the Baltic Fleet for a sortie. After new reports revealed the indecisive result of the battle, Russian Naval Command came back to the defensive.

The second and less known opportunity was in October 11th – 20th 1917: in those nine days the Grand Fleet did achieve a complete superiority in the North Sea without fighting. In those nine days the British naval forces could have blocked the High Seas Fleet in its bases and forced the Belts without fearing a strike in the back. Why? Because, for the first time since 1914, the Germans splitted their High Seas Fleet in two squadrons, sending the first (with 9 modern battleships and 1 battlecruiser) in the Gulf of Riga and keeping the second (9 modern battleships, 5 old battleships, and 4 battlecruisers) in Kiel, ready to intervene in the North Sea. Only a segment of the Grand Fleet could have achieved a complete superiority in North Sea, blocking the High Seas Fleet. Thus giving an opportunity for an entry in the Baltic of a mixed force of battlecruisers and fast battleships, ready to fight and win a battle with any of the two German squadrons.
The Russians, invaded by Germans and attacked in the Gulf of Riga, very close to their capital, actually asked for a British incursion. Navy secretary Oliver rejected their request: the weather was very bad, then light units, minesweepers, carriers and supply vessels couldn’t take the action. And Oliver, personally, was a strong opponent of the Baltic Plan since 1914.
What if the weather was fine? What if more aggressive decision makers (like admiral David Beatty, premier David Lloyd George and Churchill, who was minister of munitions at time) could have prevailed over the “doves”?

Operation Albion, something went wrong

Operation Albion was proposed by German high naval officers of the Baltic force (but not by their commander, Prince Heinrich) and the by the Eighth Army command. It was formally endorsed by Erich Ludendorff (Cinc German High Command) on September 18th 1917. This operation aimed at gaining a strong position in the Gulf of Riga seizing the islands at its mouth. The tactical goal of the operation: open a new supply line for the German troops in Riga and enable them to advance further in the North, aiming to Petrograd. The strategic goal was far more ambitious: strike a deadly blow to the weak Russian provisional government with a humiliating defeat, forcing it to sign an armistice. There was a lone voice of dissent: Prince Heinrich, commander of naval forces in the Baltic. The large amphibious operation required half of the HSF, leaving few forces to close the Baltic entrance. The fear of a British entrance in the Baltic (the “Case J” as the Germans named this option) prevented any previous large naval operation in the Eastern Baltic. In case of “Case J”, Germans planned a counter-strike (both by land and sea) against the neutral Denmark, just to break the British naval supply lines through the Danish Belts. But the Operation Albion required all the amphibious units required for the “Case J”, thus living only the possibility of a land operation against Denmark. Now the OHL and the Admiralstab are much more confident because of the extreme military weakness of the Russian enemy and the extreme prudence of the British naval strategy. They endorsed a very quick and successful operation (7-10 days), considering that in this very short period of time, a British offensive in the Baltic was nearly impossible.
In OTL this almost unknown battle was one of the most immediate causes of the Bolshevik takeover in Petrograd.
So I’ll put my POD right here.

October 11th: the German Operation Albion begins. The main target are the islands in the Gulf of Riga. A huge naval task force takes position in the Eastern Baltic Sea. Troops from 131st and 138th Regiments, plus two cyclist assault battalions embark in Libau.

October 12th: Germans attack Tagga Bay in Oesel Island. But the first landing units hit the Russian mines and sink. Alerted by huge explosions, Russian garrison immediately opens fire on the approaching enemy. The Russian local command orders 426th and 472nd Regiment to reach coastal defenses. German 131st and 138th Regiments try a landing, but they are met by an intense infantry fire, supported by two batteries. The German fleet’s big guns (especially the 15inch guns of the SMS Bayern) raze to the ground the two coastal batteries of Hundsort and Ninnast, but the landing operation is almost failed in the end of the day. Germans never succeed in consolidate a beachhead and suffer heavy losses all day. The cyclist assault battalion lands in Pamerort (East to Tagga) and it advances to the Arensburg-Orrisar road. But it met the Russian 425th Regiment and the attack failed. The cyclist battalion is dispersed before the night. Many of its assault troops are encircled and captured. The second cyclist battalion advances directly to Orrisar, but its advance is stopped by the 107th Russian Regiment. During the night, German destroyers of the Rosenberg Flotilla try to force Soela Sound, but they are intercepted by the Russian light cruiser Makharov and the attackers have to call off the action.
In London, the Russian ambassador and the naval attaché appeal to the British for immediate assistance. Petrograd fears now a direct attack by the Germans and this explain the sense of urgency with which letters are sent to Admiralty and the Prime Minister. Russian officers wonder if it might be possible for the British Grand Fleet to undertake an offensive, with so much of the German fleet in the Baltic. Admiralty declined the proposal. Both Admiral Jellicoe and Naval Secretary Oliver consider an adventure in the Baltic too dangerous. But Prime Minister David Lloyd George is favorable. He understands that Russia has to be kept in war on Entente’s side and a success of a German final blow against the outer defenses of Petrograd, could knock it out. Intensive consultations begin between Lloyd George and the Admiralty.

October 13th: Russian 426th and 472nd Regiments, supported by 425th (coming from South) keep the Germans on their precarious beachhead in Tagga Bay. Thanks to battleship’s covering fire, German repulses all attacks. But the losses are very high and the Germans succeed in advancing beyond their beachheads only that night. In the meantime, Russian regiments successfully entrench in the provisional defensive line Pamerort-Arensburg, reinforce the Orrisar field fortifications and the lines of the Sworbe Peninsula. German naval operations suffer a no less tragic humiliation that day: the light cruiser Emden tries unsuccessfully to force Soela Sound. Attacked by a Russian destroyer flotilla and shelled by coastal batteries, the Emden has to call off the action. The same happens in the Irben Strait: German minesweeper, supported by the big guns of the fleet, try to clear the Irben strait. Shelled by the 13inch guns of Zerel fortress, they have to call off their action.
During the night, the Russian minelayer Pripyat drops a new line of mines in the entrance of the Soela Sound.
In London, both Lloyd George and Churchill (minister of Munitions) wanted a bold naval operation in the Baltic. Eric Campbell Geddes, First Lord of Admiralty joins the pro-intervention party that day. They are attracted by the perspective of a German decisive naval defeat, exploiting their difficulties in the Baltic islands. The commander in chief of the Grand Fleet, David Beatty agree with them. He considers a Baltic operation feasible, if Germans suffer a “new Gallipoli”.

October 14th: While the land operations begin to enter a stalemate, the German navy suffers an unexpected and decisive blow at sea. The German battleship SMS Kaiser hits a mine and sinks while it was trying to force the Soela Sound. The sinking of the SMS Kaiser is also a severe blow to land troops morale. And a decisive good news in London. The Admiralty begins to change its attitude. While Oliver is always against a Baltic incursion, admiral Jellicoe, pressed from above (by Lloyd George and Geddes) and from the bottom (Beatty and the Grand Fleet officers).

Sorry, it remains blatantly impossible to make such an invasion. Indeed if the Royal Navy did, the ships would have been sunk on the way. If the RN did Britain would have had to surrender the very next day. Furthermore SMS Kaiser would have needed more mines to sink. ASB.
What would happen during Albion: Half of the RN has to guard Wilhelmshaven. But now they had to guard it much closer to the coast. Just to be sure. Then they would have to act in the very vincinity of German minefields and Uboats. This and sorities of the German fleet with hit and run tactics would have caused losses. Also: How would the fleet be able to stop the HSF to use the Kiel Canal? Only within the German national waters. Within the ranges of everything the Germans had. And sending half of the fleet would be a very bad idea. Even with the smaller forces Germany had these forces would be overwhelmed.
However, if you send the whole RN into the Baltic, you would lose nearly every ship. The Baltic entrances were mined. And the British had to act quickly. With other words they had to sacrifice older ships to make a passage into the minefields. Ultimately they would run out of these old ships. Furthermore they would have to fight through the Danish and Swedish waters. In such a moment this would be considered as British declaration of war. In this moment the HSF was already alarmed. Uboats would be on the way to attack the enemy fleet. I guess if the British reached Copenhagen half of their fleet would be lost.
Okay, they would be now in the Baltic. Still mines, planes and Uboats would attack them and cause severe losses. The Glorious class BC were all sunk after hitting mines or met heavy German ships. They were nothing worth. One of them was indeed crippled by 15 cm gun OTL.
When the British invasion force finally dropped the rest of the soldiers in Pommerania, the Germans already had built up defensive lines. They would land there without many supplies and soon run out of ammo. Even if they landed and conquered Kolberg or another Pommeranean coastal city they would have no chance to be resupplied. After at last two weeks they had to surrender.
And the RN? Only a few ships might get through the gaunlet again. Most of them would be sunk while trying to get to a Russian controlled harbour. Now the HSF would try to make the coup de grace and sink them. Albion might have to be delayed somewhat, but would have in contrast seen the death blow of Britain and Russia.
Ironically the Petrograd government could now save their ass by asking for peace in the light of a British defeat. And Britain without the fleet was unable to do anything now and had to fear herself an invasion. Also 10 of thousand British soldiers and sea men had died for nothing than suicide.
Without Britain France would have collapsed as well as Italy.
Game over!
However, such an invasion must be planned for months. If they did not coincidentally tried that with Albion together, they would have not been able to do so. Otherwise: ASB!
Such an invasion generally seen is IMO not ASB, but suicide. If you think the Brits would never had done so, then you can call it ASB. Indeed Seelöwe would have had better chances to succeed.

Yes. But even greater ASB factor. If Seelöwe = ASB, this = ASB³. I mean the British fleet could also set the white flag and drive to the Jade. Same effect, less dead.

Adler, I see you are really sure about your alternative timeline, not about the mine. Which is not yet written, nor published. Who's speaking about a... British invasion of Pomerania? Where? I've not yet expained British plan, nor its execution. But, if you want to make your own timeline, you're free to write one, of course.
 
The rate of communication is way too fast for the time period. There won't be next day reports at the Admiralty about what went on the night before.

The Baltic Plan was a smoke screen to justify the construction of the Courageous, Glorious and Furious large cruisers. These ships were primarily designed to serve as heavy scouts for the Grand Fleet. The British possessed few escort ships that could maintain speed and position with the battleline in heavy seas.
 
October 15th: Island of Oesel, German 131st and 138th Regiments frontally assault the Russian Pamerort-Arensburg line supported by heavy naval fire. Arensburg hold, but the northern sector of the line is breached, thanks to the naval support. Russian 426th Regiment is routed and all the Russian line has to be evacuated during the night. Units of 472nd and 425th Regiments withdraw to the Orrisar beachhead, already defended by the Estonian Regiment and a Death Battalion, sent from Reval the previous days. Russian lines in the Sworbe peninsula repulse a first German assault. German naval activity is limited to support fire for ground operations.

In London the intensive debate about the intervention reach a first compromise. An entry in the Baltic Sea is too dangerous, even if half of the High Seas Fleet is engaged in the Gulf of Riga. There are many and strong arguments against such an action: mines in the Belts, heavy coastal batteries, Danish inevitable reactions and the possibility of the main squadron of the HSF crossing the T of the approaching British naval force. But now the case for an intervention to help Russia is too strong. David Lloyd George want an "initiative”. This “initiative” is a plan drawn that same night: an important show of force in the Kattegat, in international waters, but close to German defenses. It is believed that German U-Boats are too slow to track a battlecruiser and fast battleship squadron and that German air forces are too imprecise to hit those targets. If Germans want engage and destroy a British surface naval force in closed waters they have to do it with surface battleships. An important British naval force inside Kattegat is too dangerous to be ignored by Berlin. Admiralty knows that the Germans fear an incursion in the Baltic, especially in such a vulnerable moment. Both Jellicoe and Beatty know that German strategy aims at the annihilation of a segment of Grand Fleet, in order to achieve numerical superiority in the next battle. Then, David Beatty plans to send in the Kattegat that “important segment” of the Grand Fleet, to drag the HSF out.

This strategic concept is well explained by Winston Churchill: “What then would draw the German Fleet from its harbors with the intention of battle? The blockade had not provoked them; the passage of the Army did not tempt them, idle demonstrations off the German islands ought not to have enticed them. Something must be discovered and done which when done would immediately be insupportable to Germany, which she could by no means sit still and endure; something so urgent, so clamant, so deadly that whatever the odds her whole fleet must be engaged”. This “something” is an incursion in the Kattegat, in that dangerous moment, with a force strong enough to fight and endure a short battle, weak enough to create a sense of an easy victory in German minds.

The British task force in the Kattegat:
Light Battlecruisers: Glorious and Courageous
Carrier: Glorious
Battlecruisers: Repulse, Renown, Inflexible, Indomitable
Battleships: Revenge, Royal Oak, Royal Sovereign, Resolution, Ramillies
Fast Battleships: Queen Elizabeth, Valiant, Barham, Malaya, Warspite
One squadron of light cruisers
Two destroyers flotillas
One minesweepers flotilla

Eight hours after the departure of this force, the entire Grand Fleet will leave Scapa Flow.

This task force, under admiral Packenham, has to cross the Skagerrak and enter the Kattegat, aiming south at high speed. The Grand Fleet has to follow in the North Sea. After the light forces are resupplied, a show of force in the Grand Belt, during the night, with some minesweeping actions, is also scheduled, in case of German lack of reactions. Only in case of German total passivity, the Grand Belt could be forced. German destroyers flotillas could be overwhelmed. Submarines and air forces are not powerful enough to stop such a task force. In case of an HSF sortie from Kiel, the Kattegat task force has to retreat at full speed to the Skagerrak, engaging a rearguard fight. If the Germans don’t detect the Grand Fleet and try to follow the British task force until the Skagerrak, the whole fleet of David Beatty could intervene and engage the enemy with overwhelming fire-power. If the Germans detect the Grand Fleet and/or don’t try to follow the British task force beyond the Belts, or the Northern part of Kattegat, the British could at least have accomplished a humiliating raid inside German inner waters. If the German want to re-unite their naval forces, they have to call off the action in the Gulf of Riga: it’s enough to achieve a main strategic goal of the operation.
In any case, Admiralty values the whole operation very risky, but feasible.

I like the idea but I think you're missing the big picture all that really needs to happen is to blockade the Germans and gain naval superiority in the Baltic then you can supply Russia more adequately and possibly avert the October Revolution keeping Russia in the war.

Additionally you need many soldiers for such an operation. You need them fast. And you can't assemble 100 k (or more) soldiers in England within 9 days and then attack, if you are fighting Germany in France. There are not so many soldiers to curve up. If you can curve up a division it is the most you can IMO. And that would be suicide to land.
If you send in ships to supply Russia, you might succeed to have some supplies sent. But most are sunk or captured and the fleet escorting it, too. The surviving ships would be bottled in the Russian harbours and eventually had to be scuttled when the Germans come.
I read about much idiocy within the Royal Navy in that days, but they did not even dare that. Unfortunately IMO.

Adler
 
I don't agree with you, Adler and Danwild6: this a very limited ATL on a specific situation. Royal Navy aims at gaining superiority in the Baltic and establishing a close blockade on Germany. The Operation Albion gives them an opportunity (may be unique opportunity) to attack the HSF while it is split in two.
Russians don't need manpower, nor supplies: they have already all what they need. If you want supply them, all you have to do is send more troops in Murmansk and, by rail, in Northern front. You don't have to open a new supply line: the Murmansk-Petrograd, in 1917, is enough. Russians don't need more troops, guns or ammos. They need a stunning victory in order to boost their morale.
 
Wow! I just heard about the Baltic Plans and although you've made clear they will be different i can't wait to see this play out as long as its not ASB.
