Air Strike, Rangoon
1) The sub war near Rangoon gets serious. Patrol zones re-adjusted south and to deeper water, but before the boats can position many fleet DDs jump on O24 in two attacks and sink her. Halibut is also worked over farther south. S-39 takes three hard hits near Mergui. Elsewhere, near Denpasar, SS KXIII puts one in xAK Terukawa Maru. Sinking noises heard later.
2) Today, most Allied air in the Burma theater is aimed at Rangoon in an attempt to flood the zone and whittle down CAP ops points. The carriers, Wasp and a slightly damaged RN hull (don't recall which) move in close to the coast NW of Bassein. Rangoon shows 65 fighers in residence. I figure a lot will escort the troop bombing, but there will be at least 20-30 at home. In a gamble, all Wildcats on Wasp are sent to escort the strike, which is limited to four hexes. LRCAP from Ramree and Prome will try to help, and one small squadron of Sea Hurricanes is left off the RN CV. It's a gamble he doesn't have standing 2Es on naval/torpedo every day, but it's a one-day thing. Won't work twice.
An expensive attack starts the run, but it does the job of using up some CAP.

The other Rangoon strikes do not fly. Not many, but they don't. Too small I think. Then the naval effort comes in. The RN carrier does not launch any of its Albacores, a key to the attack plan. Probably due to lack of escort. Trade-off, trade-offs.
It works through the CAP pretty well, but the newer Zeros do get at the SBDs at the end. Unfortunately, despite multiple runs on a nice CA, and two destroyers, damage is light. The xAK will sink, but I had hoped for a lot more. Still, this tactic complicates the defense problem for Japan at Rangoon. He can either withdraw the permanent bombardment force, or assign a lot more CAP, which lets me get at the bombers troop-bombing more easily.

3) Some of the MUTTLEYS are very close to the rally hex and will close its hexsides in 1-2 days. It remains to be seen if enough is left after the troop bombing. About 250 are lost today. I have a contingency plan in mind if the attack on Moulmein fails.
4) DD Fortune, fleeing Soerbaja, is overcome by flooding half-way to Batavia and sinks.
5) Soerbaja is supply bombed. At the dot hex being attacked to open supply routes to Batavia, Japan has move din a full division and the attempt fails badly. Soerbaja is sitting at about 11,500 supply with no air ops or construction at all.

6) Rabaul AF goes to Level 6. A key to keeping the B-17s repaired. Their HQ is co-located, supply is six-figures, av support is lavish. Now they need to fix themselves so Truk can be re-visited. More 4E units, mostly B-24s, are coming soon. Rabaul is going to be a major PITA.
7) The second attack on Chungking is made. Forts drop a level to 6; they can't be repaired with 420 supply on hand. Japan loses a lot of men. China loses a lot of men. Time continues to tick by.

8) Chinese leadership has ordered several low-level, unsupplied LCUs, such as Construction Regiments, out of Chungking to take hexsides in all directions and complicate siege supply. One tries to move across a river when it shouldn't have, and gets clocked.
