In autumn-winter 1942. There were plans for enormous counter offensive which had the task of destroying the Wehrmacht with three tactic operations which will make an strategic operation and therefore victory. First, colonel general Vasilievski should surround and destroy the VI German army at Stalingrad with operation “Little Saturn”. After doing this, “Saturn” should focus an attack on Rostov to trap and destroy Army Sub-group A in the Caucasus. At the same time of “Little Saturn”, marshal Zhúkov should launch operation “Mars” in Moscow area, surround and destroy the German IX army. After “Mars” and “Saturn”, “Jupiter” will come, to encircle and destroy Army Group Centre. The key of this was the Maskirovka. Let the Germans know that they were not going to attack and if they did that they did not know where, how and how strong the attack would be. We know what happened with “Little Saturn”. The Germans did know about the bad and vulnerable position of the VI army but the flanks were not reinforced because our intelligence had made clear (thanks to the Maskirovka) that the real attack was going to happen in Moscow, so IX army was reinforced instead of the VI. Once “Little Saturn” was launched we did not realise about the real danger because the Maskirovka had made us believe that it was a weak attack… That operation was supposed to destroy an army of 90.000 men, not 350.000. It went far better than planned. But, thanks to Von Manstein’s skills and strong positions, “Saturn” could not be launched and Army sub-group A was retired from the Caucasus relatively untouched. And, in Moscow, even if the Maskirovka disguised the strength of the attack, “Mars” was a total failure because the attack happened in the very place where was expected. Then, what do you think? Imagine that "Saturn" and "Mars" had succeded. Could "Jupiter" have been launched? What would have happened then?
