What were Soviet plans for Uranus at Stalingrad and how were they kept secret?

[HarperXW]

I was reading about the Battle of Stalingrad and I keep hitting a wall trying to understand the specific Soviet operational planning for Uranus. The maps show the pincer movements, but I can't grasp how they managed the sheer logistical secrecy and troop concentration without German intelligence catching on. The scale of that deception seems almost impossible for the time.

I have flipped through the maps a bunch and it kept nagging at me how they moved by night and used trains to keep the scale hidden. It felt less like one big trick and more like a steady game of concealment, only a few folks knew the full plan while most kept their heads down on the right sector.

Secrecy there sounds like it depended on stubborn compartmentalization and tight radio discipline. Orders filtered through chokepoints, messengers kept to their lanes, and the rest did their jobs without knowing the whole picture. It was not a single stunt, more a quiet wall of uncertainty for the enemy.

Logistics kept their heads above water in winter too. They fed fuel, ammo, and replacements to the right units without tipping off where the main push would land. The pincer looked flashy on a map, but underneath it was a logistics chore that would have collapsed without steady supply lines and local improvisation.

Maybe the real issue is whether the Germans were fooled so much as whether the Soviets could keep the encirclement fed once it started. The plan asked a lot of discipline and risk in winter terrain. The term Uranus pops up, but I am not sure I understand how much of that success was true disguise and how much was plain stubborn logistics.
