No. Long ago, in the Eastern Front Deluxe days, there was a game hovering the horizon, Road to Stalingrad. It never cam to fruition. The closest you are likely to find as a supplement is
Little Saturn. Most of Dr. Mike's attention went to Operation Mars, which was dealt heavily with in
Heroes of the Soviet Union,
Red Warriors and
Tank Battles.
There are a couple of scenarios which have come up from the Stalingrad campaign.
Attack on Stalingrad deals with an infantry fight during the advance on on Stalingrad watch out for the big typo in the scenario information).
Stalingrad Fire Brigade is about one of the relief efforts.
Operation Winter Storm is a home-grown mini-campaign, originally by Norman Smith. I later updated it to fit with EFDx and the newer rules. In 2012 a former PG player, Vince Hughes, mad a comment about wanting a Stalingrad map, so
I made one. It is to scale and quite big.
