WEELLY SUMMARY
Henry
My weekly summary will follow. However, I want to report a special success in the Burma Air War.
The attack on Mandalay went particularly well.
Recall, yesterday I wrote that Intelligence reported two Nate Sentais – the 24th and 50th were defending Mandalay. The AVG – the Nate Killers of Central China – had been moved to Yunan, which is within range of Mandalay. Furthermore, the 7th Bomber group was ready to return to the fight. Therefore, General Pownall gave orders for both units to attack Mandalay.
Well, things did not go as well as they did in central China. For one thing, the AVG is down to half strength, and we are finding it impossible to find additional planes for them. But, they went well enough.
We had an extraordinary stroke of luck. The P-40 Tomahawks of the AVG arrived only minutes ahead of the bombers. As soon as the AVG arrived, they challenged the Nate Sentais engaging them in a fierce dogfight where they shot down 12 of the fighters. By the time the bombers showed up, the Japanese CAP was out of ammunition and fuel and was rearming on the ground.
This gave the bombers a clear run of the airbase, and they plastered it. Bomb assessment reports show extensive damage to the airfield facilities, and the destruction of several airplanes on the ground – including at least two Zero fighters.
If I would have known that the two air groups would have arrived at the target at the same time, I would have had the heavy bombers arrive at a lower altitude for greater precision.
At the same time, we flew our regular missions against Myitkyina. It was not our best day. There is evidence that the pilots are getting tired. However, I can only speculate that the Japanese forces at Myitkyina are suffering the effects of these daily bombing missions as well.
Port Moresby Captured
This fact also deserves a mention before I get into my weekly report. The Japanese force of 17,000 soldiers marched northwest from their landing beaches and into Port Moresby, forcing the garrison there to surrender. There were only 3,500 allied soldiers to resist the Japanese invasion. They were heavily outnumbered.
Ships of the Japanese navy provided artillery support for the advance, laying off shore and directing their fire to anyplace showing active allied resistance. The guns from the cruisers that participated in these attacks proved quite effective, allowing the ships to keep enough distance to prevent any counter-battery fire from the defenders.
So, Port Moresby is now in Japanese hands.
Overall
I am in a bit better mood than I was last week. We made a decision to start fighting back against Japan, and that decision has paid off. In the past week we have:
(1) Bombarded Nanomea Atoll twice
(2) Struck at Sapang on the eastern tip of Sumatra for good effect
(3) Organized an attack on the 24th and 50th Fighter Sentais in Burma to good effect
(4) Employed our intelligence capabilities to track down and destroy a Jap submarine
(5) Maintained air supremacy over the Japanese base of Myitkyina in northern Burma.
Of course, at the same time, we
(1) Lost Port Moresby
(2) Lost the Santa Cruz Islands
These are in addition to the expected losses of additional bases along the northern coast of New Guinea, in the Dutch East Indies between Bali and Timor, and in the central part of the Philippines.
Anyway, it is time for the update.
Losses
Naval Losses: 35 Ships (1 ships lost in the last week)
• BC Repulse
• CAs: Houston, New Orleans
• CLs: Du Ruyter, Danae, Tromp
• DDs: Panther, Flusser, Lawrence
• PGs: Isabel, Asheville
• SSs: S-38, KXV
• ASs: Otus, Canopus
• DMS Southard
• MSW Penguin, Turkey
• PTs: PT-21, PT-31, PT-32, PT-34, TM-13, TM-14, TM-15
• AP President Madison, Hugh L. Scott*
• AKs, Large: Steel Voyager, Mormacdove
• AKs, Small: Taurus, Empire Elk; Governor Wright; Idaho
• TKs: Gertrude Kellogg, Manataway
* Newly sunk ship
Air Losses: 1434 Planes - 69 in the last week
• 688 planes shot down (+18)
• 455 planes destroyed on the ground (+7)
• 38 planes destroyed by flak (+4)
• 253 planes lost due to accident and wear (+40)
Top 20 Air Losses by Type
• 155x P-40B Tomahawk (+1)
• 120x Hurricane (+7)
• 102x Buffalo
• 89x Whirraway
• 87x Hudson (+10)
• 84x P-40E Warhawk (+2)
• 78x Brewster 339D
• 51x PBY Catalina (+4)
• 43x B-17 Flying Fortress (+6)
• 42x Martin 139
• 38x SB-2c
• 32x Blenheim IV (+3)
• 31x P-39D Airacobra (+4)
• 29x Blenheim I (+4)
• 28x CW-21B Demon
• 27x P-36A Mohawk
• 27x C-47 Dakota (+3)
• 25x F4F-3
• 25x LB-30 Liberator (+2)
• 25x Catalena I (new addition)
The heavy loss due to wear and tear are due to the heavy use of airplanes in Burma on combat missions. The types of planes suffering these losses -- B-17s, C-47s, Hudsons, Blenheims -- are all plane types being heavily used in the India/Burma campaign. The only method we have available for reducing these losses is to quit using these airplanes. That seems like a less than ideal way to win a war.
Airplane Shortages
I have mentioned before the airplanes that we have shortages in. I thought, this time, I would tell you how great our shortages are -- how many airplanes I need just to bring existing squadrons up to full strength.
In this report, I will give this week's number before the airplane type, showing last week's number in parentheses after the aircraft type.
• 11x Brewster 339D (16)
• 19x Buffalo I (24)
• 51x Catalina I (48)
• 12x Martin 139 (14)
• 07x P-26A (10)
• 66x P-36A (66)
• 25x P-39D Airacobra (21)
• 87x P-40B Tomahawk (92)
• 33x P-40E Tomahawk (40)
The situation has somewhat improved since my previous correspondence. However, at this rate, it will still be a very long time before we have all of the fighters that I was originally promised to this theater.
Damage Inflicted
Military intelligence estimates the losses suffered by the Japanese to be the following
Enemy Naval Losses: 15 ships
This includes 1 enemy submarine sunk in the past week.
• 1x Destroyer
• 9x Submarines
• 1x Minelayer
• 2x Minesweeper
• 1x Cargo ship
• 1x Troop transport
Enemy Air Losses:
These, of course, are approximations.
Air to air combat: less than 200+
Flak: 120
Destroyed on the field: 40+
The successful attack on the Nate squadrons at Mandalay today was the major contributor to the increase in Japanese losses due to air-to-air combat and on the ground.
Summary By Region
North Pacific
"Horseshoe"
CV Enterprise and CV Hornet are on the last day of their journey to Paramushiro Jima. Tomorrow, I will be reporting the effects of their attack -- provided that the weather allows them to have an attack.
• Kiska: Near the tip of the Aleutian Islands, MSW Oriole has just returned from its most recent mission to the Kurile Island, where it once again reported that it was possible to get to the Kuriles without being spotted by air. The island is also mined.
• Amchikita: 250 miles east of Kiska, AVD Gilles and VP-41 (12x PBY) to patrol the approaches to Alaska.
• Dutch Harbor: 400 miles east of Amchikita, 26,000 troops + 1200 combat infantry. 24x obsolete fighters. 32x Bombers.
• Kodiak: 350 miles northeast of Dutch Harbor; 20,000 troops + 2300 combat infantry.
• Anchorage: 4600 troops. Canada has leant the 13th Canadian Brigade to help in the defense of Anchorage. However, the unit is traveling over land from Canada and has several weeks to go.
• Nome: 6000 troops + over 1100 combat infantry.
Central Pacific
Japan holds Guam, Wake, and Baker Islands. Nothing else that started in Allied control (with the exception of Pearl Harbor on December 7th) has even been subject to attack.
Engineers have built a crude port and airstrip at French Frigate Shoals and on Laysan Island (400 miles southeast of Midway). These airstrips will allow us to ferry shorter-range aircraft from Hawaii to Midway.
There are about 96,000 troops on the Hawiian Islands themselves (from Big Island to Lihu), with garrisons at Pearl, Hilo, Kona, and Lahina and Lihu. The 27th USA Infantry Division is on Big Island. The 102nd USA Regimental Combat Team now occupies Lihu, 100 miles west of Pearl Harbor. These units will prevent Japan from easily landing on these islands and threatening Pearl Harbor.
Palmyra: 16,500 troops, 24x fighters, 56x bombers, 12x Patrol planes, 1100+ mines
Christmas Island: 24,000 troops plus 1900 combat infantry. 16x bombers. 12x Patrol planes. 500 mines.
Nimitz has made the decision to occupy Jarvis Island, a small island about 250 miles southwest of Chrismas Island. Its purpose is to give a little more protection across the gap from Christmas Island to Canton Island or to Pago Pago (if Canton Island should fall to the Japanese). Its purpose is to add one more headache to any Japanese attempt to capture the Line Islands -- the chain that includes Palmyra and Christmas Islands.
Johnson Island: 4,700 troops. This island is also at risk. With a fairly well developed airfield, it would be useful for Japan to keep Hawaii in check. It needs reinforcements.
South Pacific
Japan occupies Nanomea Atoll and the Santa Cruz Islands (or, at least, Utupau at the center of the Santa Cruz Islands)
Nanomea is a small island sits about 600 miles south of Apamama and Tarawa in the Gilbert Islands. In the past week, Halsey sent a small collection of cruisers to Nanomea twice to disrupt Japanese activities there. The damage was minor though, hopefully, it will have an effect on the morale of the Japanese high command, and make them more hesitant.
• Canton Island: 15,000 troops, 30x fighters, 40x bombers, 12x patrol planes. Transport ships are again visiting this island without any hindrance from Japan. Supplies are plentiful as a result.
Military intelligence has been giving some thought to how Japan would move to take possession of the South Sea Islands. A likely line of attack would be to take Canton Island, thus cutting off the rest of the islands (forcing supplies to go around and preventing allied ships from having direct access to a major base).
For this reason, orders have gone out to help Canton Island fortify itself. TF1337 was just 400 miles away from Pago Pago when the 19th USA Engineering Regiment when our discussions ended. Halsey ordered the engineers to Canton Island to help that island prepare its defenses.
Canton island cannot hold many more soldiers. However, at least none that are there will find it easy to actually use those facilities.
• Samoa (Pago Pago): 24,500 troops split between American Samoa (14,500) and British Samoa (10,000). Also, holds the fighter, bomber, and torpedo squadrons of CV Saratoga while that carrier undergoes repairs for a torpedo hit at Pearl Harbor. Added to this, the islands have 12x Patrol Planes, 21x Fighter, and 16x Bomber.
Pago Pago has fewer soldiers than it had on the last report because of a decision to occupy Wallis Island to the northwest about 400 miles. Units of the 2nd USMC Division left Pago Pago to occupy this island. Pago Pago has the 102nd Regimental Combat Team to protect it.
• Tongatapu: 3,800 troops, plus 60x bombers flying ASW missions along the route from Samoa to Fiji, and 12x patrol planes carrying out reconnaissance.
• Wallis Island, northeast of American Samoa. 2000 troops belonging to the 2nd USMC Division.
• Fiji: 13,800 troops (New Zealand), 70x bombers. 30x patrol planes.
The strength defending this island has decreased because of the threat to New Caledonia discovered over a week ago.
I was looking over the South Sea Islands and started to look at the map under the assumption that Japan occupied the New Hebrides Islands as well as New Caledonia. I asked myself to consider the best line of advance, and discovered that Efate was the best place for an additional island. It is the only island in this chain that would be within the range of bombers flying from an allied base.
I mentioned to Nimitz the idea that the first base we would land on should be the last base we are driven out of. We should move our resources to Efate.
Another argument for defending Efate was that New Caledonia is large. It is not possible to protect the whole coastline. As a result, Japan can land without opposition, rest, and move on the capital over land. On Efate, Japan cannot get to the shore without facing defensive guns.
As a result, Halsey has ordered the transfer of Hobart Coastal Artillery Regiment from new Caledonia to Efate, by air and by sea (whichever is the most practical). In addition, the First New Zealand Cavalry Brigade is being listed from Suva in Fiji to Efate before the Japanese can get there.
• New Caledonia: 4,000 troops, 1 squadron of Hudson bombers. Reinforcements for the island, which is calling itself the Americal Division, is about 600 miles northeast of American Samoa on its way to New Caledonia. If they can arrive on time, they can go to work fortifying New Caledonia. However, we do not know how much time the Japanese are going to give us.
Southwest Pacific
Japan has taken all of the Solomon Islands and all of New Guinea including Port Moresby, except for a small number of scattered bases that will fall under Japanese influence quickly enough.
Port Moresby fell to the Japanese today.
• 7th Australian Division: The 7th Australian Division will arrive this week (on Thursday, if I remember correctly). It can be immediately transferred to ships in the local theater and sent to help defend New Caledonia.
• Australian Navy: North Coast. CL Boise is the only allied surface ship left in the waters north of Australia. It was only here because it was too badly damaged to go anywhere. Many of those damages have been patched, and Boise will soon take its poor battered body to Perth.
• Supplies: A steady stream of supplies and reinforcements is nearing Australia. Even if it is cut off by the Japanese occupation of New Caledonia, Australia will have a healthy stockpile of supplies. It will be able to execute a war against the Japanese, if they invaded, without much risk that they will run out of supplies. In the mean time, the British continue to supply Australia from the west through the Indian Ocean.
• Air Power: The Ships from the United States have also brought four fighter groups; three with P-39D Airacobras and 1 with P-40s. It also imported the 24th Fighter Squadron from the Philippines, as well as the Dutch air force. This gives Japan a sizable air force to deal with in case of an invasion.
ABDA Command
Sumatra, Borneo, Java, Sulawesi, all are occupied by Japan. The Allies have Timor and a few smaller islands.
• Timor Timor has been largely abandoned, except for a token force at Koepang, on the western tip, and a small garrison of 10 fighters and a like number of bombers. Koepang is significantly short of supplies. There is no expectation of holding the island. As soon as the Japanese show up in force, the defenders will, as much as possible, retreat to the mainland.
• Aru Island: As mentioned above, this has proved to be a bad idea. Japan moved on Bali with a force of 45,000 soldiers, all landing in 1 day. If they do the same to Aru Island, it will quickly fall. Rather than risk the loss of another group of soldiers trapped, we are withdrawing units from this island. Soldiers are being moved off by seaplane to Port Moresby.
Burma
Japan occupies all of Burma.
Allied units, including nine Chinese "Divisions" and the whole of the British army in Burma minus one air force sergeant, are marching out of the jungle to India.
This has turned the battle in Burma into an air war. We are flying regular missions against the Japanese forces at Myitkyina to good effect. Strategic bombing has left the region around Pagan a near wasteland of no practical use to Japan. It has taken similar action against potentially useful resources around Taung Gyi, to somewhat less effect.
The Indian air force is making no attempt to tackle the Japanese Zero. Thus, the area around Rangoon remains safe. Allied bombing missions are focusing instead on northern and central Burma.
Ceylon
The British have over 40,000 troops on Ceylon -- including the 18th UK Division -- to resist any Japanese invasion of this island. They also have 10x fighters and 70x bombers, and 12x patrol planes stationed on the island, with 20x more fighters at nearby Madras.
As is being done elsewhere, engineers are focusing on fortifying their positions rather than building infrastructure. Once the fortifications are in place, the infrastructure will be built up behind them.
There are troops stationed at every port on the east shore of India -- including (from south to north) 7,000 at Mannargudi, 3,500 at Madras, and 2,500 at Yanam.
China
Japanese forces finished their project of clearing the Shanghai-Hanoi railroad a couple of weeks ago. It then moved its main army north, and launched a campaign that drove through Homan and took the town of Sian.
In doing so, Japan has captured approximately half of the Chinese war factories that China had available on December 7th. The only source of complex manufactured war material will have to be flown in from India.
The AVG and the bulk of the Chinese air force has moved to Yunan to protect the airfields there from Japanese assaults. Those airfields will be used to receive supplies from India.
Closing Comments
These weekly reports leave me exhausted. If you should find a group of strange letters in the middle of one of these reports, it is because I fell asleep and my head hit the keys. But, I hope you find it useful. At least you know that you never have to go far to catch up with what has happened.
Tomorrow, "Horseshoe" launches. The forecast is for rain. Hopefully, there will not be so much rain that we cannot launch our planes against the island. I am going to be camped at the radio tomorrow waiting for the results.
