The Soviet advance into Berlin followed a pattern of massive shelling followed by assaults using house-clearing battle groups of about 80 men in each, with tank escorts and close artillery support. On 27 April, the remnants of Nordland were pushed back into the central government district (Zitadelle sector) in Defence sector Z. There, Krukenberg's Nordland headquarters was a carriage in the Stadtmitte U-Bahn station. Fighting was very heavy and by 28 April 108 Soviet tanks had been destroyed in the southeast of Berlin within the "S-Bahn". The French squads under Fenet's command accounted for "about half" of the tanks. Fenet and his battalion were given the area of Neukölln, Belle Alliance Platz, Wilhelmstrasse and the Friedrichstrasse to defend. On 28 April, the Red Army started a full-scale offensive into the central sector. Charlemagne was in the center of the battle zone around the Reich Chancellery. French SS man Eugene Vaulot, who had destroyed two tanks in Neukölln, used "Panzerfaust"s to claim six more near the "Führerbunker". He was awarded the Knight's Cross of the Iron Cross by Krukenberg on 29 April. Vaulot was killed three days later by a Red Army sniper. Second Lieutenant Roger Albert-Brunet destroyed four Soviet tanks by "Panzerfaust" on 29 April 1945. He was awarded the Iron Cross 1st class by Krukenberg. During the fighting, Fenet was wounded in the foot. The Soviets forces drove what was left of the battalion back to the vicinity of the Reich Aviation Ministry in the central government district under the command of SS-"Brigadeführer" Wilhelm Mohnke. For the combat actions of the battalion during the Battle in Berlin, Mohnke awarded the Knight's Cross of the Iron Cross to Fenet on 29 April 1945.
