In the First Ukrainian Front's attack from the Neisse River into Saxony and the Brandenburg area, the 3rd Guards Army attacked north of Cottbus into the Spree River. Part of it also attacked Cottbus and captured it. However, the 3rd Guards Army did not head north into the southern suburbs of Berlin. Koniev had angled the 5th Guards Army left towards Spremberg and the 3rd Guards Army to the right to force the German troops back into Cottbus. A few days after the great Soviet offensive of April 16, the 3rd Guards Army kept the pressure on the Germans around Cottbus.
Konev was warned of the mass of German troops in the Spreewald. He expedited the 28th Army's advance that was intended to seal the gap between the 3rd Guards Army, effectively finishing off the Germans in the Cottbus area, and the 3rd Guards Tank Army. On April 25, when the First Belorussian Front was fighting in the city itself during the Battle of Berlin, the 3rd Guards Army was rushed into positions close to the Berlin-Dresdenautobahn "to block all the forest roads leading from east to west." Gordov's troops chopped down tall pine trees to form tank barriers. However, the 3rd Guards Army did not manage to occupy the southern part of its sector, which meant that there was a gap between it and the 28th Army. However, that did not matter that much since German resistance in eastern Germany was now very limited, as the Ninth and Twelfth Armies were retreating towards the Elbe River, and resistance was limited to small pockets of concentration.
After the Berlin operation, the Army formed part of the Soviet force for the Prague Offensive.
