Hello Alex, just wondering if you want to have the full loss list (or as much as possible) for 23rd FG, or if you are interested only in MACR.
The book "Sharks over China" had 6 pages (281-286) listing men of 23rd FG who died during WWII. KIA, KIFA, killed by Japanese bombs.
Just for the beginning of 1943, before the loss you list on 8 April (that is also in the book)
43/01/12 P-40 (no serial) 16th FS 1st Lt L F "Chip" Myers KIFA en route to Yunnanyi
43/01/16 P-40 (no serial) 16th FS 2nd Lt George V Pyles KIA Yunnanyi
43/02/11 P-40K-1 (no serial) 75th FS Lt William T Cross KIA strafing troops Nan Sang bridge
43/03/19 P-40 (no serial) 74th FS Capt Raymond W Lucia KIA ground fire near Mangshih
43/03/29 P-40 (no serial) 74th FS 1st Lt Robert E Atkinson KIA strafing Chefang
43/04/01 P-40K-1 41-5567 75th FS Capt Burrall Barnum KIA dogfight Lingling
Other losses where pilot survived are given in the narrative.
Before 1943, 16 pilots died in 1942 (8 KIA, 8 KIFA).
