In early October 2011 appeared in Poland article, which I am the author. It is dedicated to little known history of Soviet aviation activities on the Polish in September and October 1939. This issue is very often underestimated in various studies. Soviet airmen led active combat operations against the Poles from 17 September to 6 October 1939. During this period, have done a few thousand sorties: most reccon flights, less on bombing and shelling the Polish army.
Russians to the invasion of Poland gathered 3,300 combat aircraft. With this size used operationally much less. In the text presented to the state of Soviet aviation, its combat operations in 1939. I gave examples of air fights between Polish and Soviet aircraft and other combat operations. Russians shot down in aerial combat at least 4 aircraft (P.11, p.23, RWD-8, R-XIII).
Article is titled "Soviet Air Force over the borderlands in 1939," The text has 10 pages (page 68-77) and is illustrated with 21 black and white photographs.
