Dmitry,
My mistake on the date (Bad habit of scribling to many notes all over one sheet of paper). On
www.bellabs.ru the article "Archive 51-Mine-Torepedo Regiment KBF" by Miroslav Morozov was were I found the information. The correct date listed was the 17Sep41 and the target area was Uritsk-Ligovo(?). Lt. Borzov led 6 DB-3 and lost 3 to fighters. The OBD has one crew lost for that date under 1 AP KBF but to antiaircraft fire. I have found a few of his dates wrong in the article before and had to double check to find the right date. The Luftwaffe units have two DB-3 claims on the 17Sep41 but at different times and no location. On 19Sep41 there are claims for 3 SB-2 in the Uritsk area in the morning.
