There were numerous gross errors regarding Tania Chernova:
--She was blond
--Before the war she was studying medicine
--She was not from Stalingrad and was not in the city militia
--Prior to arriving in Stalingrad on 23 Sept 1942, she had become a relentless killer of Germans as a partisan in Byelorussia and the Ukraine
--As she arrived in Stalingrad, her barge was sunk and she had to swim to shore; once there, she crawled through a sewer to reach the city, but accidentally came out behind German lines. Behind enemy lines, she boldly walked into a German mess hall to get food before finally reaching Russian lines.
--Chernova became one of Zaitsev’s sniper students and his lover. During her training, she was sent on a mission to blow up a German command post. Prior to lighting the fuse on the dynamite, she engaged in hand-to-hand combat with a German sentry and crushed his windpipe with her hands.
--During another training session, Chernova disobeyed Zaitsev’s orders not to fire and engaged a German infantry unit, killing 17 enemy soldiers. Unfortunately, she also gave her sniper team’s position away--the resulting artillery counter-fire killed many of her friends and caused Zaitsev to slap her and berate her for her stupidity.
-- Chernova became an accomplished sniper. After getting 80 kills, she was severely wounded while on a mission when a clumsy woman directly ahead of her stepped on a land mine; Zaitsev carried her back to a field hospital.
--Chernova and Zaitsev never saw one another again.
Zaitsev learned to shoot while hunting deer in the forests around his boyhood home in the Ural mountains. Zaitsev was not semi-illiterate, he attended technical school and became a bookkeeper in the Soviet Navy Far Eastern Fleet.
Danilov played a small role with Zaitsev. Col Batyuk, not Danilov, told Zaitsev of Konings arrival. Danilov was wounded in the shoulder by Konings in an act of stupidity, not killed as shown in the movie.
While a Russian shoe shine boy was executed by the Germans for spying, he was not killed by Konings and he was not involved in the Zaitsev-Konings encounter.
Kulikov was Zaitsev’s close friend and had not studied in Germany with Konings before the war. Konings was laying down in a hide made of rubble with a sheet of iron over the top when he was killed by Zaitsev; Zaitsev shot him between the eyes after Konings was tricked into thinking he had made a kill on Kulikov, and Konings raised his head away from his rifle. Kulikov was not killed by Konings.
