The 244th Division was trikov's stronger force, with 3,685 men and 29 guns and 115 mortars, as well as 19 machine guns, 1,130 rifles, and submachine guns. The 10th Infantry Brigade had 1912 men and 26 mortars, 45 machine guns, 1166 rifles and submachine guns. The 271st Regiment of internal affairs has about 2,000 people and is well armed with light weapons. Roughly estimated, the Soviet infantry in this area is equivalent to 5-6 battalions. The Germans had 13 stronger infantry battalions, more than double the size of the Soviets. The Germans had a greater advantage in firepower.
In addition, in the southern suburbs (south of Sadovaya Station), the German 29th Motorized Division, the 14th Panzer Division, and the 20th Romanian Infantry Division were responsible for the assault from the Kuporosnoye area, severing the defensive line between the Soviet 62nd and 64th Armies in order to completely isolate Trikov at Stalingrad. The main attack of the 29th Motorized Division and the 14th Panzer Division was directed at the 35th Soviet Guards Division. The 35th Guards Division had only 454 men and had 6 guns, 3 machine guns, 386 rifles and submachine guns. Undoubtedly, its strength was not enough to resist the overwhelming advantage of the German army in front of it.
On the eve of the attack, soviet night aircraft buzzed all night on the heads of the Germans, constantly flying at high altitudes and low altitudes, and dropping a few bombs from time to time, making the Germans unable to rest and overwhelm. In order to deal with these aircraft, the german 48th Panzer Army Commander Kempf asked the night fighters to take off to intercept them. Outside the city all the searchlights of the Romanian 6th And German 4th Army were towed into the positions of the 48th Panzer Army.
The Germans stayed up all night, and finally arrived at the early morning of Sunday, September 13, 1942. At 6:45 a.m. Soviet time and 4:45 a.m. German time (Hitler insisted that the Germans on the Eastern Front follow East Prussian time), the Germans began to attack, and the Battle of Stalingrad was officially launched.
