Operation Sea Lion in Global 1940 (Alpha 1+)

I have now played 1.5 games of the new Alpha setup and done some serious planning and thinking about Sea Lion. The new Alpha set up seems to get Operation Sea Lion about right in my opinion. Here is how I see it. Let me know if I am missing something here or there. My conclusion, as boring as can be, is that the setup in Alpha 1+ with or without the Strategic bomber, is fine.

Operation Sea Lion is very often successful unless the British bring their Med. Fleet up to the English Channel and block. The threat of Operation Sea Lion, however, is significant enough that it saves the Italian fleet, allows Italy great freedom in the Med, and forces the US to seriously consider helping in Africa.

Germany Turn One: Germany purchases an Airbase for Denmark and 2 transports. Germany takes out as much of the British fleet as possible on Turn One, moving Baltic Fleet into 112 and using Subs and airpower to eliminate ships in 111 and 98. Germany takes France, Finland, Yugoslavia, Bulgaria and Southern France. Land units move toward Western Germany. Airpower stationed in Denmark and Western Germany, allowing six fighters/tacticalsto defend SZ 112. Germany collects 70 IPCs (41 plus 19 from France plus 10 from bonuses).

Germany Turn Two: Germany purchases nine transports and 2 infantry. Germany moves land units to Western Germany. Airpower attacks UK ships if isolated.

Germany Turn Three – British Med Fleet Still in Med: If no serious British fleet blocking, Germany lands on UK with 12 Infantry, 6 Artillery, 6 Tanks and a varying amount of airpower but likely 5 fighters, 4 tacticals, and one bomber. Defenders optimal defense force is 24 British Infantry, 1 French Infantry, 2 British tanks, 4 British Fighters, 1 French Fighter, 1 British Bomber. Germany takes United Kingdom over 70% of the time.

Germany Turn Three – British Med Fleet Recalled: If the British fleet has been brought up from the Med and now blocks German attack, Germany calls off Sea Lion and instead invades USSR because the numbers begin to run against Operation Sea Lion as UK infantry build up combined with the German losses that would be sustained in an attack on the English Channel fleet and any scrambled British airpower. USSR now becomes only real option. Of course, the threat against England has saved the Italian fleet, which should take Gibraltar as soon as the British leave the Med., delaying any reentry into the Med. by the Allies. With the Med. secure, the Italians are free to take Egypt and to help in the new front against USSR. The Italians could still have major problems from the British and the Americans, but Operation Sea Lion has given them options they would otherwise have been denied.

One point to note, esp. in reply to other threads on the subject, is that Germany in my opinion should be dictating events and not UK. It is Germany that should threaten Sealion and force UK to choose what they want to do. Other threads have made it seem like UK can dictate to Germany. I don't see it that way. If Germany chooses to not threaten Sealion, they have made a strategic choice that dooms the Italian navy but helps them vis-a-vis USSR. In my opinion, Germany should threaten Sealion, just as they did in the real war. This may mean that they allow USSR too much time to prepare for their invasion, but such is the risk one is taking as the Axis. I think the real idea is that the Axis should be putting pressure on the Allies all over the map, forcing them to make all the right moves, and taking advantage of any mistakes or periods of bad luck. If the Allies respond appropriately and luck is even, the Allies should win most of the time, just as they did in the real war. I know, however, that others want the game to be a bit more balanced. In that case, my suggestion is the good ole bid system of yonder year.

Just a quick question?

having enough men for 13 boats is possible, how come didn't buy 13 transports.

I do agree with you that Sealion helps with the Med quite a bit.

Its too hard for the UK to prevent the Germans invading the UK, especially with all that French money. Even buying all out infantry starting turn 1 will not be enough to prevent Germany from invading the UK.

I think it would be a good idea to move the UK fleet a bit more out of range of the german air units, or increase the size of the fleets scattered across the Atlantic. In return, make the UK fleets around the Med smaller, so as to make an attack against Italy a risky concept.

Buying 13 transports is possible, but my thinking was to purchase an airbase for Denmark because it allows for six planes to Scramble to defend SZ 112. If you don' do this, your fleet can either be sunk by UK or blocked by a UK destroyer, etc. moving into SZ 112. Before the new scramble rules, the airbase was replaced by an Aircraft Carrier that served a similar role (albeit not as effectively).

Aircraft carrier is a better choice in my opinion. It serves a longer logistic need in the long run and gives your boats an extra hit.

As for the 13 transports, you can get 13 by buying two on G1, and 10 on G2 if you get 70 ipcs

It really does make the difference. Additionally killing british transports is important to make sure no units make to England to reinforce. The kicker is bombing england's ipc center. You guaranteed to cost them at least one infantry and if you send enough interceptors you might scare England out of even putting up a fight. (overwhelming force is imperative to scare the defense out of defending)

Presumably the Med UK fleet has two purposes:

1. To force the Germans to destroy it using their air power, rather than using German air power to attack London.
2. To prevent bombardment during the invasion of London by the German Battleship and Cruiser

IMHO, there is no "absolute right way" to do Sealion, and all of your ideas are good, and could be great, depending on the circumstances. Here are a few of interesting things that can happen, and make things even WORSE for the UK and it's a "depends on" situation.

1. Germany can land in Scotland on Turn 2, assuming there is German fleet to defend the transports. This works well if the UK has sent airplanes south to defend the Med fleet. Either way, UK is in tough spot, to counter attack Scotland is to weaken London prior to the Turn 3 invasion. To not counter attack is to allow more Germany troops to attack London, both from Scotland and amphibiously.

2. From SZ112, Germany can amphibiously attack London from SZ 109 and SZ110. Thus, a naval confrontation is sometimes avoidable completely by the Germans.

3. Germany can move one or more "blocking" warships to SZ 104 or SZ110 to prevent the UK fleet from reaching the channel in time.

4. If the UK fails to reinforce its Med fleet with more planes to scramble from Gibraltar on the way home to the Channel, the Italians can attack and sink a significant portion (if not all) of the UK fleet on its way home.

Sealion success chances are high if done right. Just threatening Sealion strengthens Italy greatly. With all that French money in German hands, UK player must assume Sealion is coming or risk losing the capital.

Operation Sea Lion Global Move-by-Move

Uses 12/27/2010 Larry Harris Alpha Suggested Set Up

German Turn One

Purchases: Two transports, Airbase for Denmark

Combat Moves: France (with 7 infantry, 2 Mechs, 3 Artillery, 3 Tanks), Southern France (with 2 Tanks, 2 Mechs), Finland (with one infantry), Bulgaria (with one infantry), Yugoslavia (with 8 infantry, artillery, 3 Tanks), SZ 112 (with BB, CRUS, DEST, Tactical Bomber, Fighter), SZ 110 (with 2 Submarines, 2 Tactical Bombers, 2 Fighters, and the Strategic Bomber) and SZ 111 (with 1 Sub, Tactical Bomber, 2 Fighters). During this aggressive German turn, it is likely the Germans will lose a couple of air units along the way.

Noncombat Moves and Placement: 6 Infantry, 4 Artillery in Germany move to West Germany; Poland and Slovakia Infantry move to Germany, land three fighters in Denmark, rest of airpower in Western Germany, Place Transports in SZ 112, Place Airbase in Denmark.

UK Turn One: Purchase 9 Infantry. Move CRUS, DEST, AC to Gibraltar East, land Malta Fighter on AC along with Tactical. Move Destroyer from SZ 108 to SZ 110 to prevent bombardments on German Turn Two. Move CRUS in 91 to Gibraltar East SZ. Move Gibraltar Fighter to UK, Move Scotland Fighter and Infantry to UK, Move Tank, Infantry from Canada to UK, Move Canadian Destroyer to Gibraltar West. Move two fighters from UK to Gibraltar for defense of Fleet. [This should be enough to prevent a German Two Operation Sea Lion. AA Calculator says Germans win no more that 14% of the time. If UK sends just one fighter to Gibraltar, percentage drops to just 4.8%.]

Italy Turn One: Attacking UK fleet seems a major gamble though it could be done to weaken UK’s defenses for Sea Lion on Turn Three. Assume that the Italian fleet eliminates everything but the three fighters, which would be a good result, this is still not enough to allow Germany to win on Turn Three Invasion. If Italy does focus on UK Fleet, some of the French fleet should be able to move out of Med and will be able to defend Sea Lion on Turn Three. All in all, it is hard from the Italians to eliminateall of the Allied navy, though they can gamble, sacrificing their navy for a winner-take-all Sea Lion invasion on Turn Three.

France Turn One: Move what survives of the Med. Fleet to link up with surviving UK Fleet or best location for Turn Three defense of England.

Germany Turn Two: Purchase Ten Transports. Clear SZ 110 if anything moved in. Move all units to Western Germany.

UK Turn Two: Purchase Ten Infantry. Move what remains of UK Fleet to SZ 110. Move airpower to UK for defense.

Italy Turn Three: Help clear 110 if possible. Take Gibraltar to prevent easy return of Allied navy.

German Turn Three: Attack UK? There should be at least a few allied ships in SZ 110 and UK can scramble up to three air units, meaning Germany must allocate some of its airpower to the Sea Zone. If they allocate a very minimum amount, say one Tactical Bomber and one Fighter (to go along with BB, CRUS, DEST) and win in the sea zone (because England declines to scramble for example), the chances of taking England are still just 50%. If they must allocate more than this, their chances drop dramatically to 40% or 25%. All of this seems very risky to me, and I would not suicide the Italian navy against the UK Fleet for a best-case scenario of 50% to take UK.
