Are the Japanese Army sentai operation records on this website:


If not are they accessible anywhere else?

Thanks
 
If I wanted to find the 85th sentai's combat log for example how would I use this link?
 
These are the 85th sentai history from March 1, 1941 to August 3, 1945.

The 85th Sentai

In early July 1944,
Began to updated the model to Ki-84. 4 were brought to Guangdong from Hankou.
As of August 1, the sentai owned 22 Ki-44s and 3 Ki-84s.
9 Ki-84s were added from Hankou soon.

In September 26,
the 22nd Sentai handed over 6 out of 9 Ki-84s to the 85th Sentai and returned to the homeland to prepare for the Philippine Air Battle.

In October,
85th Sentai fought well against the P-51B/Cs.

On October 4,
Captain Wakamatsu led 4 Ki-84s and 4 Ki-44s for patrol near Wuzhou when several P-51B/Cs of the US 76th Fighter Squadron attacked the ground. Wakamatsu and his team downed 4 with no damage on Wakamatsu side.

On December 18,
12 Ki-84s of the 85th Sentai and 13 Ki-43s from the 25th Sentai encountered a US large formation, including B-29s, in Hankou.
3 Ki-84s and 2 Ki-43s, including Wakamatsu's, were lost. Combined with AA fire, 4 P-51s, 1 P-40 and 1 B-29 were shot down.

On January 3, 5, 6 and 14, 1945,
Hankou air raid by the US. 85th Sentai and 25th Sentai intercepted. 6 were lost in action but, combined with AA fire, 8 P-51s and 4 P-47s were shot down.

On January 17,
The 85th Sentai and 25th Sentai intercepted P-47s. 1 each (total 2) were lost. 2 P-47s were shot down.

Thank you very much for your responses. The first pages you posted here appear to just be the locations of where the 85th Sentai were based:
These are the 85th sentai history from March 1, 1941 to August 3, 1945.

This is what I was looking for and some of the combats mentioned are new to me. I am interested in learning more about these ones you mentioned here:

On January 3, 5, 6 and 14, 1945,
Hankou air raid by the US. 85th Sentai and 25th Sentai intercepted. 6 were lost in action but, combined with AA fire, 8 P-51s and 4 P-47s were shot down.

On January 17,
The 85th Sentai and 25th Sentai intercepted P-47s. 1 each (total 2) were lost. 2 P-47s were shot down.

Are there any books or websites you would recommend I use in order to learn more details about these battles?


One more thing, do you have 85th or 22nd sentai victory claims on 13 and 14 August 1945 over Korea?

These two P-47Ns were shot down over Korea in engagements with the 85th and 22nd sentai:

P-47N loss of 13 Aug 1945 (# 3) was 44-88232, damaged by Ki-43 near Seoul and lost. MACR 14840, Pilot 1st Lt Dallas G. Yeargain POW. See National Archives NextGen Catalog

Another P-47N of 507th FG lost was 44-88118, shot down by a Ki-44 on 14 Aug 1945, also in the Seoul area. See MACR 14871 here: National Archives NextGen Catalog
Pilot 2nd Lt William L. McDaniel, Jr. POW.



Do you have any victory claims made by these two sentais on these days?
 
Thanks for the amazon link. It's fine because I already have loads of books that are really big!

"Japanese Army Air Force Fighter Units and Their Aces: 1931-1945" by Ikuhiko Hata and Yasuho Izawa will be a bible.

As far as I have researched, such a regional combat in Korea seems to be paid little attention by historians.

One strange thing I noticed about August 1945 is that there seems to be confusion over Korea and Kyushu.

On 13 August 1945 Oscar Perdomo was credited with five victories in one day but some sources say it happened at Keijo, Korea while others say Kyushu.

On 14 August 1945, William McDaniel was shot down by "Tojos" or "Hiens" and yet again some sources say Keijo while others say Kyushu. I found a victory claim made by a Ki-100 which was right on the northern tip of Kyushu on 14 August

I'm curious if you think it's possible to mix up Keijo and Kyushu and what your opinion is on the two events on 13 and 14 August I just mentioned?
 
Keijo(Seoul) is a little bit far from Kyushu though the 85th and 22nd Sentais were going to attack the Allies fleet in Okinawa from Keijo.
Sorry but no idea.
No worries, I think I've worked it out actually.

Just one more question:

Does Japanese Army Air Force Fighter Units and Their Aces: 1931-1945 have detailed descriptions of the air battles or would you say it's more generic?
