Cape Esperance for Nimitz

Post by foxbat »

Hello,

I'll be demonstrating the rules at the club next month, though my experience with them is still nil... I've devised a Cape Esperance scenario, which will be the main course, and an introductory game around the battle of Denmark Straight (should be the 4th set of rules I use to play it) as an appetizer. The idea is to introduce players to the besics with Denmark Straight, and add torps and night fighting with Cape Esperance. Not sure these will work though. If any of you can give a bit of time to read and review them, I'll be obliged. Thanks in advance. ;)

Hello. Sorry I missed your post until now.

I have read both your scenarios and (at this point) read but not played Nimitz. I have played Cape Esperance.

Denmark Strait
This seems simple enough. Both Holland and Lutjens were expecting a battle; the main difference was that Holland knew what ships he was facing.
  • You don't state the starting positions: the German squadron presumably starts in the yellow square, but where do the British start?
  • I like that you have a special rule to try to model the Prince of Wales's lack of time to work up her turret machinery and gunnery crews.
  • You don't have a rule to model the British confusion between the similar silhouettes of Prinz Eugen and Bismarck, which caused Hood to fire at the less dangerous cruiser by mistake.
  • The Germans win if Bismarck escapes undamaged to attack the convoy routes. I'd say that's a major German victory, not a minor one.
  • Your victory conditions make it a draw if the Germans sink Hood (30 points) but Bismarck is damaged, but a minor victory if they sink Prince of Wales (35 points) but Bismarck is damaged. I'd say those are equivalent results. Losing either capital ship is a minor disaster for the British.
  • You could have a rule to bring in the cruisers Norfolk and Suffolk under certain conditions (or roll of dice).
Your English is excellent and far better than my French, but a narrow body of water is a 'Strait', not a 'Straight'. thmbs2)

Cape Esperance
This is harder to set up because it was a night action. Goto was taken completely by surprise; Scott, by contrast, knew the Japanese were coming. In a reversal of what happened at Savo Island in August, Goto was also confused because a Japanese transport force under Rear-Admiral Joshima (with the seaplane tenders Chitose and Nisshin) was also on its way to Guadalcanal and feared his ships were engaging the Japanese convoy. If I recall correctly, Rear-Admiral Scott initially tried to cancel the order to open fire, worried that his ships were firing on friendly ships.
  • Wasn't Scott between Goto and Savo Island? You have Goto arriving next to Savo. It doesn't really matter.
  • Scott made a mess of his deployment, forcing his destroyers to overtake his cruisers as the action began.
  • You don't give the Americans any initiative to reflect Scott's knowledge that the Japanese were coming. You could give the Americans the initiative for the first turn (which I think is about 12 minutes in Nimitz).
  • You don't give the Americans any advantage from having SG radar. The cruiser Helena knew the Japanese were coming five to 10 minutes before the American ships opened fire. Scott, on San Francisco, didn't take advantage of that knowledge. Do the rules give ships with radar an advantage in a night action? I don't remember.
  • I think your French and English victory conditions are different: "l’Américain marque 6 points si aucun CA ennemi ne peut passer" versus "the US side 6 VPs if no Japanese ship can get through, including DDs". It doesn't really make sense for the Japanese to deny the Americans 6 VPs if a destroyer gets through as destroyer guns wouldn't have damaged Henderson Field.
  • You don't have Joshima's seaplane tenders or Tanaka's escorting destroyers. I didn't either.
When I played this, I had a few special rules to try to reflect the confusion aboard both flagships:
  • Each Japanese ship had to roll 3+ on a D6 to open fire because the ships are not expecting to meet an American force, are confused about which ships are enemies and may believe they have stumbled into their own convoy in the dark. Add +1 to the roll if the flagship Aoba has successfully identified the American ships.
  • Poor communications mean that each American ship except Helena (with SG radar) must also roll 3+ on a D6 before opening fire, as they are confused as to which ships are enemy ships.
I think the problem with any special rules in Nimitz is that the turns represent so much time (i.e. about 12 minutes) that a restriction in one turn could mean the battle is all over. So I'm not sure I would use any as I'm not sure how they would affect the game.

I hope that helps. :)

Thanks for your comments, and having taken the time to think about my work.
Regarding the battle of Denmark Strait, here is what I had in mind when I designed the scenario : the historical result was a decisive German victory at 71 points (Bismarck exited with minor damage and no reduction in speed, Prinz Eugen was not sunk, Hood was destroyed). Now, I’ll agree, the Kriegsmarine was somewhat lucky with Hood blowing up so soon in the battle. This is where I start treading on shakier ground, so to speak, as, well, I’ve never played the game yet and cannot claim to have the feel of it.

In « Nimitz », unlike other rule sets, Hood is much more brittle : with an Armour Value (AV) of 4, against 6 for Bismarck, it will take on average 2 more damages per penetrating hit. Also, at long range, Bismarck’s shells will penetrate 66% of the times, vs 33% for Hood. Lastly, even Prinz Eugen has a 33% chance at long range, and 66% at short range to get a penetration. This means that Hood is liable to being sunk fast, leaving Prince of Wales facing Bismarck. The Prinz has no chance to penetrate its armour indeed, but if it loses a turret, it loses 40% of its fire power. My feeling is that the German side is much more powerful than in other sets.

Regarding Norfolk and Suffolk, well, their mission was not to engage and keep shadowing Bismarck : I think they’d have attacked only when Bismarck was already done for, so I kept them out wholesale to things simple (this is an introductory game in fact).

Regarding the supposed mix up of Bismarck and Prinz Eugen, there is no agreement that it actually took place (saw some accounts of the battle that categorically reject it….) so I kept it out as well. Now, that could be an optional rule : the German player has blinds instead of models on the table, they are not revealed till the KM ships fire…
« Your victory conditions make it a draw if the Germans sink Hood (30 points) but Bismarck is damaged, but a minor victory if they sink Prince of Wales (35 points) but Bismarck is damaged. I'd say those are equivalent results. Losing either capital ship is a minor disaster for the British. »
This is a very good point, thank you. This should be more consistent this way :
36-64 pts: victoire mineure / minor victory
30-35 pts:match nul / draw

I opted to make it a bit harder for the KM. Indeed, losing any ship is a minor disaster for the RN, but the Bismarck losing 2 speed boxes is a guaranteed destruction later (the only way in this game this can happen is if the ship is crippled). Needless to say, I’ll take into account what happens next Saturday when we play at the club.


Now on to Cape Esperance. You’re mlaking a lot of very good points, I asked myself these questions, but I feel somewhat constrained by the rules themselves.

Regarding radar, for instance, you don’t get any advantage for detection or targetting in the rules. In fact, you get a different set of data cards (labelled « 44 ») for these ships that make it this far into the war, especially on the Allied side. Now, I did not feel it would be right to use them that early, sinbce, after Morison, radar was a newfangled technology that was barely understood (and this was not the case for Norman Scott). In fact, Helena could not communicate with the flagship its findings. Regarding surprise too, Scott was expecting an enemy supply convoy (Joshima), and certainly not Goto. And Tanaka was a bit too far as well. The truth of the matter is that all this is exceedingly complex to simulate, at least for me, so I opted for the lazy option and left it out . And you nail it perfectly :
« I think the problem with any special rules in Nimitz is that the turns represent so much time (i.e. about 12 minutes) that a restriction in one turn could mean the battle is all over. So I'm not sure I would use any as I'm not sure how they would affect the game. »
Indeed, my feeling is that games can be short. The dilemma for the US player will be that he needs to open fire : if he does, his ships are illuminated, and can become prey to Japanese Long Lances out of small guns range (16 inches vs 24). At such a distance, all LL torpedo mounts will need a 6 to score, which gives a 50% chance of sinking a cruiser…
Regarding US initiative advantage, well, Scott did not really make great use of it (you can give a side a bonus to the roll in Nimitz BTW), so I admit, I just did not take it into account.

Regarding Savo, you are right : it would be better in the lower righthand corner. I’ll update it, not that it is very important. And you’re very correct about US VCs, I’ll add the DD blurb to the French version.

Once again, Hawke, thanks a lot : you’ve been very helpful, and I think you the games will be better with your advice. Cheers !

Very interesting. I hope to test the Battle of Denmark Strait soon, having finally splashed out on nice models of the Bismarck and Prinz Eugen that I need to finish painting.

You are right. I hadn't spotted that. Sam Mustafa has indeed given Hood an armour rating of 4, the same as Repulse and Renown. But Hood wasn’t designed as a larger Repulse or even a 15" Tiger; she was designed as a faster Queen Elizabeth. She had a 12" main belt, comparable to the 13" belt on the Queen Elizabeths, so her armour rating probably ought to be the same: i.e. 5.

I like your approach of calculating the hit probabilities.

My understanding was that Vice-Admiral Holland wanted them to engage Prinz Eugen, but they were not in position to do so because he had not broken radio silence to tell Rear-Admiral Wake-Walker his intention. Suffolk did fire six salvoes at 0619, having mistaken an aircraft contact on her radar for the Bismarck, but was out of range. But, yes, leaving them out keeps things simple.

I have a copy of the British Naval Staff History from 1950. On page 7 it states: “At 0549, the left-hand ship, the Prinz Eugen, was designated as the target by the signal G.S.B. 337 L [which means fire at the left-hand German ship bearing 337°], but this was changed to the Bismarck by the signal G.O.B. 1 just before opening fire [shift object one right].” So Hood was definitely confused. But you are right and I was wrong to say that Hood fired at Prinz Eugen by mistake because the mistaken identification was corrected before opening fire.

Good luck. :D
