This is mostly from the Book "The Russian Military Air Fleet in WW I Augie Blume
Order of battle KAOs August 1914 North West Front
Russian 1st Army 2,3,4,10 KAO
Russian 2nd Army 1,13,15,21,23
In the battle of Tannenburg where the Russian 2nd army was defeated the 13 KAO lost most of its equipment in the retreat the other KAOs also lost some of their equipment. The Germans reported that the Russians rarely flew beyond the Russian front line and their commanders if they got a report from their airmen didn't believe them! I also heard from a friend that the Russian XV corps commander while he complained bitterly about german aircraft flying over his command in a post WW I interview didn't order the 15th KAO under his command to fly a single recon mission! The Russians did have a few aircraft lost or damaged during this battle:
26 August 15 KAO one aircraft shot down by it own sides ground fire the crew survivied but was taken prisoner when the XV corps was encircled and captured.
27 August 13 KAO one aircraft MIA
28 August 15 KAO one aircraft lost engine trouble
29 August 21 KAO one pilot wounded by ground fire plane damaged but the pilot was able to land the plane
I hope this is of some use or interest.
James, thanks so much for your post about the details of the Russian air force at the battle of Tannenburg. I always have to translate dates into old style dates, which would have been 13-16 August 1914.
I know you have told me already, but what would you estimate the time of departure of the Tsarevich Alexei Hospital train from the Tannenburg battle?
I know the exact time the hospital arrived at Petrograd's military processing station on 17/30 August, but after processing I do know it was halted by the Empress at the Tsarskoe Selo train station late that same night.
