鳕鱼战争（Cod wars）

As  冰岛 capitulate the  UK.

「Strategy」

Go historical.

Technically, ahistorical can slightly help if you give everyone their historical routes except  日本, who you reset repeatedly to try to get them to go 共产主义 or 民主主义 so they don't attack the  美国 (who then in turn will not join the 同盟国). However, "Historical AI focuses off with AI countries manually set to historical routes" is extremely different behavior-wise from "Historical AI focuses on". Many times, the AI will just ignore your suggestion that they do their historical route and instead do something else. So you will experience a very heavy amount of variance if you're trying this.

Initial Setup

• Create a naval queue for Convoys. Don't forget to assign the Infantry Equipment queue your MIO, since for some reason it starts unassigned.
• 你的头几项科研按以下顺序进行：电子机械工程、基础机床、早期巡洋舰、集中工业 I、无线电、集中工业 II。之后照常推进科研，重点放在计算（至少前 2-3 项科技；其余不值得）、无线电、工业、步兵装备、卡车／列车、火炮和防空（大致按此顺序）。
  • The reason for these researches and this order is to pump out ships as fast as possible. You need the 海军船坞 production boost from Concentrated Industry II as fast as possible in order to meet our aggressive schedule for the first invasion.
• 在冰岛你的首都排入几个海岸堡垒和陆上堡垒；你多半完不成它们，但那没关系。如果完成了，就建造基础设施。
  • For the most part, we will be using our 民用工厂 for International Market purchases anyway.
• Complete the focus Mineral Prospecting and start Not Our King.
• 用第一项焦点获得的民用工厂，开始从市场购买装备，并在接下来几年里持续这样做。你要以步兵装备为重点，牵引式火炮为第二优先。
  • You only need around 180 Towed Artillery at the most, so you can grab some trucks and trains later on if you feel you're set on guns and artillery.
• Hire the Progressive Doctor as an advisor.
• Start the focus Anti-Capitalist Propaganda and hire the 海军航空兵（专家） as Chief of Navy once you have the 政治点数.
• Start the focus Expand the Industrial Base and hire the 纳粹同情者 as an advisor.
• With your 海军经验, create the most basic Early Destroyer design possible (add a Light Battery). Delete your Convoy build queue to force your 1 海军船坞 to instead build this Early Destroyer. Make sure you set the build quantity to 1.
• Once your Early Cruiser research finishes, do the same thing you did above (add a Light Battery and a Fire Control 0 to make the design). Add a new Naval build queue for it with the quantity set to 1.
• Complete the focus Rally the Workers of Reykjavik.
• Start the focus Prepare for the Revolution and fire your Chief of Navy (click his portrait then select him again from the list). Rehire him, now as an 陆军操练（专家） for Chief of Army.
• Start the focus Organize a March.
• Once you have 20 陆军经验, alter your starting Infantry division template to replace the Cavalry Recon Detachment with Support Artillery and to remove two Infantry battalions (leaving 4 in the end). If you wish, you can also add Infantry Guns to the first regiment.
• 改善与丹麦的关系。
  • While the  丹麦 AI seems to slightly favor letting you break away cleanly, sometimes it still takes the option for a War goal. If relations are low, it seems to be about even odds if they'll actually use this War goal on you. If you have higher relations they typically will not declare war. We really don't want them to declare war because it can mess up your Naval invasion later.
• Start the focus Break With the Crown.
• By this time, your Early Destroyer should be done. Your Early Cruiser is probably telling you it will finish in late 1939, but once Concentrated Industry II finishes, it will bump that timeline up.
• 现在你的驱逐舰已经完工，继续把一条初始师模板加入招募队列。数量设为 5。
  • We needed to wait until the destroyer was done so that the destroyer didn't stall out due to a lack of manpower to finish the construction. We'll aim to have all 5 divisions full on manpower now before the cruiser finishes, so we don't run into a conflict there either.
• Once you're at least halfway through Break With the Crown, take the Improved Worker Conditions and Anti-Communist Raids decisions.
• Complete the focus 国际贸易 and then 国家组合主义.
• When 国家组合主义 finishes, set State serves the Military as your Spirit of the Army and then bump your Conscription law from 非武装国家 all the way up to 大规模征兵.
• From here, grab the focuses Organize the Greyshirts, Banking on the Future, and The Viking Spirit.
• When you get enough 政治点数, hire the Judge and Newspaper Editor as an advisor and the 军事理论家 as a Theorist. Afterwards, spend your 政治点数 on the Viking Spirit decisions.
• Keep collecting your new divisions as they are produced and train them up to be Veterans.
• 接下来的焦点优先选择：通过工业研究学校获得第三个科研槽、通过渗透获得免费特工机构，然后是「军队专业化」带来的增益（顺路走海军分支并点出「紧急改装」）。
  • As an aside, I do not recommend taking the three bottommost focuses in your political tree, ever. You get cores on islands that have no value if the others accept, and if they deny you, you get a bunch of permanent War goals that alter AI behavior. This is actually a bad thing. There's already so much randomness in this run; you don't want to introduce more.
  

Attack the Netherlands

• In early November 1938, justify a 战争目标 on the  荷属东印度.
• 1939 年 1 月，加入轴心国。制定一项海军登陆计划，从德国的威廉港出发，登陆荷兰阿姆斯特丹以北一格的那个港口（吕伐登以西）。把部队分配到该计划，让它们移动到威廉港。
  • Choosing this specific tile exploits the AI's troop positioning. The AI is deathly afraid that you will call in  Germany, so nearly their entire army is going to be on the German border.
  • Because the tile we are attacking is a port that isn't worth (Unrecognized string "Victory Points" for Template:Icon), it has a slightly lower garrison priority for the AI, and it will be completely unguarded.
• Create a fleet with your destroyer and your cruiser (as soon as it is finished). Set them to Patrol in the Eastern North Sea while based in Wilhelmshaven. You should aim to have 150+ Naval Dominance in the Eastern North Sea before your justification finishes, so that you can launch immediately.
• 当你的战争目标制造日期临近时（在荷属东印度外交界面查看），放慢游戏时间。你需要在制造完成的那一小时准时对荷兰宣战。不要邀请你的盟友，也不要接受他们的参战请求。
  • This exploits oversights in how guarantees work. While the  UK guarantees the  荷属东印度 immediately when you start justifying, they don't guarantee the overlord until the day the justification finishes. This gives you a 1 hour window to declare war before the  UK guarantees the  荷兰.
• Launch your naval invasion. Set your fleet to Naval Invasion Support just in case.
• The second your troops land (slow down the game speed again), leave 1 division on the port. Send 2 divisions to walk through Amsterdam to Utrecht. Send the other two divisions to walk through The Hague and Rotterdam to reach Breda.
• 如果你运气好、动作快，就会立刻迫使荷兰投降。
  • If this does not happen, don't worry. Hold the port you came in at, The Hague, and Amsterdam (in total, 4 tiles) against the  荷兰 forces until June 9th, 1939. On that date,  意大利 joins the 轴心国. This changes the surrender limit, and the  荷兰 should immediately capitulate.
  • This is probably also a bug, since it doesn't make much sense for the surrender limit to be affected when the party involved hasn't even joined the war, but oh well.
• Annex everything from both the  荷兰 and the  荷属东印度. Take their navy too.
• You should now have roughly 800k spare 人力 and nearly 30 Factories. You may think at this point "oh wow, from here it's easy". Unfortunately, no. The easy part actually just ended. For some reason, holding the Netherlands weakens the 轴心国 severely. They will likely fall before the end of 1943 due to your actions just now, which means you don't have a ton of time left.

Attack Finland

• From here, the safest choice to remain uninvolved in larger wars while growing stronger is to attack  芬兰. They are the only significant neutral country that nobody will guarantee if you attack.
• When  德国 attacks  波兰, do not accept their call to arms. We're going to exploit how Naval Dominance works when a war is declared to get a naval landing in the  UK later, which means we can't be at war with them until the moment we invade.
• Create a new division template. Use 5 陆军经验 to add a single Cavalry battalion to it and save it. Then change your Garrison law to Civilian Oversight and set the Garrison template to your new Cavalry division.
• As you gain more 陆军经验, steadily increase the combat width of your Infantry template up from 8 to 24. Add in Support Anti-Air and Engineer Company as support companies for now. You'll want to add in Recon Rangers, Field Hospitals, and Logistics Companies later as you can, but not until you're closer to being caught up on research.
• Change your Economy law up to 战时经济 and fill your construction queue with 军用工厂.
• Upgrade your spy agency 5 times so you get a second spy. After this is done, begin doing Collaboration Governments on the  UK.
• Begin recruiting more divisions of your Infantry template. Aim for 20-24. Even if they aren't fully equipped, that's fine.
• When you finish the focus Emergency Conversions, you will want to start routinely taking the decisions to "Refit ships to Destroyers" and "Refit ships to Cruisers".
• 如果你想的话，这里也可以利用一个漏洞大幅提升海军实力，但它带来的差别并不大。不过如果你确实要用：
  • Create an Early Cruiser named "Refitted Cruiser Class". Fill all the module slots out with the most expensive options. For the slots with many choices, I recommend picking the Heavy Cruiser Battery I every time. This will make a Heavy Cruiser design that's basically just a floating fortress of guns and armor, which is incredible when you're getting it for free. Save the design; it doesn't matter if a number is appended or anything, as long as the actual name field is correct before the decision finishes.
  • Repeat the above process for an Early Destroyer as well, naming it "Refitted Destroyer Class". For the Destroyer, just fill out the optional modules with whatever you wish (I went with Torpedoes). It should cost 30 海军经验 to save.
  • If you're short on 海军经验 for either design, set your entire Navy to train. It gets you 0.3 海军经验 per day based on the percentage of your Navy currently training.
  • Spam these decisions for the rest of the game to make your Navy steadily stronger over time.
• In December 1939, begin to justify a 战争目标 on  芬兰. It should take you roughly 100 days and be done in early April 1939, which is right when the Winter War should be ending.
• Plan a pair of Naval invasions from Memel to Helsinki and from Memel to Turku.
• Split your fleet into roughly 3 equal parts and Patrol in the Lower Baltic Sea, the Gulf of Bothnia, and the Gulf of Finland.
• When the  Soviets peace out with  芬兰, taking Karelia, declare war and launch your naval invasions.
• From here, bring over the rest of your forces and slowly defeat the Finnish. You can micro against them to create surrounds and take easy (Unrecognized string "Victory Points" for Template:Icon) or you can just battle plan all the way north; it really doesn't matter very much. You effectively have infinite manpower because of your advisor, so the only thing you're losing equipment, which is just time.
• Annex them and take their navy as well.

Attack the UK

• From here, the goal is to strike the  UK in mid-1942 with 48-60 divisions at a time when your technology is finally back up to par. However, you can't afford to wait any longer than mid-1942 because the 轴心国 AI is busy committing suicide, and they are highly skilled at doing this.
• Research Landing Ships. You will soon need the ability to plan 4 naval invasions at once.
• 确保继续在英国推进协作政府，并尽可能每次都执行「将舰船改装为巡洋舰」决议。（驱逐舰那个也不错，但最终影响较小。）
  • If your number of convoys begins to drop over time, build 2-3 海军船坞. It should start going back up after that.
• 政治点数的良好用途：
  • Switch out the 纳粹同情者 for the 恐怖亲王 and the Progressive Doctor for the 仁慈绅士. This will help keep your Compliance up and your Resistance down.
  • Fill out your Military Staff where possible - grab the 火炮（专精）和陆军后勤（专家）. Save the third slot for your first General to reach level 4, who you'll want promote to 「步兵（专家）」 and hire immediately.
  • After you get your initial round of 军用工厂 built in all of your states, you'll also want to drop 自由贸易 down to 有限出口.
  • Grab the Siemens Iceland Industrial Concern when you can; it's a decent research boost and reduces the amount of 煤 required as well.
• By early 1942, get all your troops lined up and trained on the coast of the Netherlands and begin setting up your naval invasions. Personally, I prefer the following four invasions:

1. From Rotterdam to the tile between Portsmouth and Dover.
2. From Rotterdam to the tile south of London, the tile east of London, and the tile south of Ipswich.
3. From Leeuwarden to Hull and the tile north of Hull.
4. From Leeuwarden to the tile north of Newcastle, Newcastle, and the tile south of Newcastle.

• The first two naval invasions go through the English Channel, and the second two naval invasions go through the Eastern North Sea and the North Sea.
• The moment you make these naval invasion plans, the AI becomes aware of them and attempts to defend against them by bolstering their Naval Dominance in the English Channel and the North Sea.
• 不过，由于你的登陆计划分散在两个地区，而且你的舰队能在单个地区提供高达 2000 的海军主导权，英国 AI 实际上无法获得足够的海军主导权来同时阻止全部 4 次海军登陆。
  • By the way, I recommend pulling your submarines off the main fleet into a second one and setting that second fleet to patrol only in the Eastern North Sea. All ~25 submarines you have should give you just over 150 Naval Dominance, and the  UK does not contest the Eastern North Sea against you until after the war starts.
• 此时从两组海军登陆中选择一组全力执行。把师分配到该组海军登陆任务，并让你的主力舰队在所需海域执行巡逻。
  • This trick exploits that when a war starts, the Naval dominance values established before a war starts are retained. If you just threw your fleet in these sea zones while already at war with the UK, they would have immediately engaged and wrecked your fleet before you were able to reach the Naval dominance threshold required for your invasions.
• When one set of the naval invasions lists as "ready", go ahead and finally 战争目标 justification on the UK and then declare war, launching the invasions immediately.
• Quickly, switch your fleet over to Naval Invasion Support. Watch the landing carefully.
• Out of the gate, we've chosen to avoid landing directly on ports for the most part in order to avoid the steep penalties associated with naval attacks against 海岸堡垒.
• But that means the second you land, you need to Force Attack with most of your divisions on the adjacent ports, while using your other couple of divisions to immediately walk around the port. If you manage to walk around it fully, isolating it, then you will usually instantly win the fight due to the encirclement penalty.
• 一旦你拿到一个港口，就建立一条元帅前线并把所有部队分配给它（留下大约 4 个师守家，防卫冰岛）。
  • Also, set all your ships on Hold now so they return to port. You don't want them fighting the Royal Navy if you can help it.
• At this point, I recommend throwing up a quick offensive line at the opposite end of the Home Islands from where you landed and setting your battle plans to Aggressive (at least at first). That combined with some manual micro, especially at the start, can help you get some good surrounds and capture some key ports.
• However, this is by far the hardest part of the run. You will likely eventually enter a stalemate against the  UK when you control about half of the country, and this stalemale can often be incredibly hard to break.
• It can be worth it to stop pushing entirely in order to allow your units time to resupply and refill their organization.
• However, remember that you have a +40% Division attack bonus for your units (possibly the single strongest division attack bonus in the entire game) through National Spirits but only a +15% Division defense bonus. This means you can sometimes get into situations where you can't hold ground against the  UK forces but you can still push them.

If you just got the achievement upon capitulating the  UK, congratulations! You're free from this achievement and can stop reading here.

Optionally, Capitulate the Allies

• 如果你没能成功，也不必太担心。由于游戏会把阵营之间的类似战争合并，有时你的「冰岛-英国」战争会自动并入规模大得多的「德国-波兰」战争。这取决于几个你无法控制的因素，包括 AI 实际决定把谁拉进每场战争，以及「意大利-埃塞俄比亚」战争是否已经与「德国-波兰」战争合并。
  • If your war was folded into the larger war, then you may not have had the required war participation to be "the country who was primarily responsible for capitulating the UK" and thus not earned the achievement.
  • Is this fixable? Yes. Will it be fast? Probably not.
  • What needs to happen now is you need to capitulate the remaining major powers in the 同盟国 (the  USA and possibly  巴西 and/or  阿根廷), act a certain way in the peace deal (keep their land from being puppeted so their tag is unused), and then release the  UK again as an independent sovereign nation (which prioritizes using the original  UK tag again if it is currently unused). Then, you just declare war on them again (alone) and run them over in a couple days. This will count, and you'll actually get the achievement.
• You'll need to immediately turn your attention towards mainland Europe. Join all wars that the 轴心国 is in (if you aren't already) and retake France, Italy, and the Balkans. Afterwards, you'll need to capitulate the  Soviets. All the while, you will have to leave a beefy naval garrison in place on the Home Islands (at minimum one full army) because the 同盟国 will constantly naval invade it.
• However, this shouldn't be too hard. Because of the Collaboration Governments on the  UK, you will now have nearly 300 factories, including nearly 60 dockyards. You can start churning out an actually respectable navy while cleaning up the  American和 英国 ones. Once their navies are crippled, you can cut the supplies going to their European fronts, starving their European armies.
• It will probably take you a while to build up your army and navy (and heck, if you've got the time, might as well pump out an airforce too; it helps in  America), but none of this should be particularly difficult compared to that fight against the  UK.
• When you do eventually get a peace deal, annex all of the  UK directly. If the AI is fighting you over a piece of land, you can let them have it, as long as they are choosing to "Take State" and not create a puppet, liberate, or change government.
• 之后，从英国领土上释放所有能释放、但并非英国本身的傀儡国（苏格兰、威尔士、北爱尔兰以及各个海外领地）。然后把英国作为独立国家释放，而不是傀儡国。
  • If everything went right, the  UK you just released should have the normal  British focus tree. If it doesn't, somebody probably puppeted some land from them and you didn't notice.
  
• Justify a 战争目标 on them, line up all your troops on the border in  苏格兰和 威尔士. Once the justification finishes, declare war, call in your puppets (to use their land to attack), and crush them.
• Now you're finally done.
