[splashell]

December 15-16th major events:

-A big event was a landing attempt on Mersing by those (probably) same barges which had been spotted for several days at Kuantan. I suspected that these barges sitting in Mersing might be actually empty, and an attempt to pull the cruiser force based on CA Houston and 2CLs into a trap. The barges were covered by a Japanese heavy cruiser force, which clashed with the Houston force, during both nights, but both fights left inconclusive leaving the barges vulnerable. My opponent says they failed to unload, I'm not sure what's the case but barges are slow and might have ended up in the hex with no ops points. 155 combat squads and 39 support squads were sunk (2500 casualties, I wonder what unit this was attempting the landing)

-Heavy bombing of Clark Field airfield on both days. Fierce air combat at both Clark and Singapore

-JNAF unit captures Attu island

-Batangas was captured, looks like, effectively a litte over divisions worth of troops and assault value heading to Manila, unless reinforcements

-Japan captures Paotow, pushing two understrength Chinese corps back

-3 fleeing xAKLs sunk north of Kuching by CL Isuzu

-2 Japanese AV and 1 SC sunk at Kuantan

-Wake Island and Jolo were captured

December 17th major events:

-sub encounter in the Makassar strait: RO-34 fires 2 torps at S-41, no hits
-PT-boats launch another attack against a new Japanese landing force at Mauban (SE of Manila): 1 DMS and xAK carrying support 53 support squads and 2 vehicles sunk
-CL Marblehead+DDs intercept Japanese shipping near Sinkawang - 2xAK, 1E heavily damaged and DD Asagiri sunk. Marblehead takes a torpedo
-Maya and Ashigara sink the Marblehead
-SS Porpoise sinks an xAK at Laoag
-Nells torpedo and sink a Dutch DD at Singapore

[splashell]

December 18th major events:

-CL Naka + DDs hunt for the remaining Hong Kong PT boats at Pakhoi
-Fast transports (CL Natori + 6DD) unload an SNLF unit at Manado
-A split 16th Infantry Regiment invades Amchitka and Adak islands at the Aleutians
-I-16 sinks an AG near Pearl Harbor
-Singapore airfields raided, several planes destroyed on the ground
-H-81s ambush Japanese bombing raid on Wuchow, shooting down shooting down several Nates and 1E bombers
-Sinkawang and Manado continue to hold

[splashell]

December 19th major events:

-I-157 sinks xAK at Batavia
-CA Houston, 2CL and 5DD clash with Takao, Chokai and CL Jintsu at Kuantan, resulting CA Houston sunk
-SS Tuna wastes and misses a full salvo of 24 torpedoes dueling with an xAK on the surface at Amchitka. The captain will be sent to the gulag!
-Japanese push on Yenan. Base is abandoned due to low value and difficulty to defend
-A divisions worth of Japanese troops march into Manila (which will be defended)
-Paratroopers capture Malacca effectively opening the railway to there. Everyone has been withdrawn to Singapore

So does that performance of the sub SS Tuna make it "the chicken of the sea?"

No, I'm just joking. And the captain won't be sent to the Gulag either.

I can imagine how hard a duel like that would be. A cargo ship at full speed at 12-14kt zig zagging and shooting back might IRL be quite hard to hit on the surface with torpedoes. Zig zagging requires a solution where basically the input speed and angle on bow is averaged out (i.e. reduced and guesstimated on the fly). Also I think the torpedo loaders must have been eating spinach that day.

I actually checked the crew on Tuna the previous day. The experience gain they got that day was quite big, day/night 54/54 -> 60/54, so maybe they will do better next time. The captain has a good naval skill of 63, but low aggression of 33, and Tuna was initially set on a minelaying mission so maybe they were caught by surprise on the surface as well.

December 20th major events:

-SS Argonaut puts a torpedo in CL Yubari near Wake Island
-RO-60 sinks an xAK near Rabaul
-SS Trout fires 2 torps at DD Kisaragi near Truk and misses. Also oilers where spotted here a few days ago (torps fired and missed)
-I-7 sinks an xAKL at Dutch Harbor
-I-124 sinks an xAKL near Pamekasan
-Subs shadow invasion fleet from Truk towards SSW (Rabaul/Kavieng, earlier Kavieng invading SNLF coy wiped out of attrition)
-I-7 puts torp in another xAK at Dutch Harbor
-Nells and Betties bomb Singapore harbor, scoring some bomb hits on various ships, including CL Reuter and DD Banckert, xAK, xAP and a CM. Many bombers were wiped out by defending Buffaloes
-Looks like a Japanese armored/cav push starting towards Lanchow, the corps in the mountains at Paotow get pushed out
-Sinkawang holds a day or few more against overwhelming odds, Manado assault was launched at 1:3 odds and failed
-Disaster strikes on Luzon where a counterattack was made at Lingayen, only to find a couple of extra divisions there. What followed was disaster and probably accelerates Luzon fall

If it was on a minelaying mission it would not have been able to fire those 24 torps you mentioned ...

Great job on Ryujo. Were you expecting it to be there or was that a random encounter? Love those Dutch subs!

It's funny, because it was actually carrying a full loadout of 26 torpedoes and 20 mines in total. I thought the torp loadout is always reduced when loading mines. Either way it laid mines and apparently after that emptied it's torps, since the next day it had 0 [:)]

Well, not really, but I suspected something will be coming at some point from Babel... I have quite extensive air coverage of the whole eastern DEI. And if something would be coming, it might as well go through that particular strait. Lucky!
