The red and Blue Plaid made sure that the Soviet army could not penetrate into the green plaid and let the German army blossom behind it. Then in the green grid, the German special forces combed repeatedly to ensure the absolute security of these areas. This set of play made the German army advance very slowly, but almost step by step. So far, no Soviet army has ever recaptured the green grid, which is the proof of the success of trohiller's tactics. In accordance with this set of tactics, it only took tricheller three months to drive the Soviets out of Stalingrad. This is the result that rokosovsky did not want to see“ It's obvious. " In his headquarters on the outskirts of Stalingrad, trohiler said to his men, "my opponent rokosovsky will not be so willing to fail. I am waiting for his counterattack, which will surely appear." What he didn't know was that the seemingly good underground bunker headquarters he was in was actually the front-line headquarters of rokosovsky two months ago, where rokosovsky personally commanded the battle for the railway bridge. As a result, the German army finally seized the railway bridge in that battle, and rokosovsky could only lose“ According to the report from the air force, their bombing effect on the routes on both sides of the Volga River was very poor. The pilots had no training to attack sea targets, and the accuracy of bombing was very low. This also led to the Soviet people easily completing 80% of the transportation of personnel and materials. " The chief of staff said helplessly to tricheler, "they said that these days at least three divisions of Soviet troops have used the Volga River route to enter Stalingrad."
