After coming across limited sources on the incident that happened on the 7th of November, 1944, all I discovered was a report from the headquarters of 866 IAP. In this report, it states that at 12:50pm 12 American planes( P-38 Lightening) attacked a Russian Infantry that were traveling west from Nish. Four of the American planes started an attack on the Russians while the rest of them was keeping watch at 1500 meters. After several rounds were fired, the Russian artillery shutting down one of the American P-38 planes. At 1:00pm, 2 YAK-9 planes took off. At 1:05pm, 6 more YAK-9 planes followed and then at 1:10pm 2 YAK-3 planes also followed. A dog fight broke out between the countries ending with 2 YAK-9 planes being taken down by the Americans and one more by friendly artillery fire. Russian planes and antiaircraft artillery shut down 5 Lightening planes. The P-38 displayed an impeccable ability to maintain horizontal and were were able to quickly maneuver onto the tail of YAK-9 planes because they had a much shorter radius of banking(turn-in). The YAK99 had better ability to withstand vertical maneuvers.
