The entire 13th Red Army stalled because of its defeat at Radzymin. After that success the Poles slowly but steadily pushed the Soviets back beyond the first line of defences that had been overrun several days before. By the end of 16 August, the 28th and 30th Infantry Regiments manned most of the trench line along the Rządza River, near the village of Dybów. Although initially, the Russian command wanted to use the outskirts of Radzymin as a pivot for a tactical withdrawal to the Radzymin–Brześć line, the following day the Soviet commander ordered a full retreat towards Wyszków and later Grodno. Meanwhile, Piłsudski's 4th Army outflanked the surprised Russians and went as far north as the left-wing of Nikolai Sollogub's 16th Red Army, which at that time was constantly pressured from the front by the 10th and 15th divisions. This made existing Russian plans obsolete, and Polish forces started a pursuit that ended with the victorious Battle of the Niemen River in September. On the day of Polish victory, the Soviets issued a propaganda poster in Moscow proclaiming: "Warsaw has fallen. With it the Poland of yesterday became history. It is nothing but a legend now while the truth of today is the red reality. Long live the Soviets! Long live the invincible Red Army!"
