the initial breakthrough and the advance via Radziechów, where the Flak crews once again showed remarkable performance against enemy tanks. The unit then drove towards Dubno, fighting in the tank battle of Brody in Ukraine, against Soviet T-34 and KV tanks; with the 11th Panzer Division being momentarily cut-off by Soviet armoured forces. The regiment then took part in the encirclement of Kiev and the Battle of Bryansk. These battles were hard-fought and the regiment took significant losses, albeit reinforcing the unit's growing reputation for steadfastness in combat. At the end of 1941, the regiment was moved back to Germany for rest and refitting, with the Schützen-Bataillon Hermann Göring remaining at the front until May 1942. At the same time, a newly formed II.Schützen-Bataillon was sent to the Eastern Front, where it was all but decimated in extremely heavy-fighting around Juchnow and Anissowo-Goroditsche. At the end of the Battle of Uman, the encircled Soviet forces attempted a desperate breakout by night, running into the 16th batterie of the Flak Regiment Hermann Göring, under Oberleutnant Karl Rossmann (aka Batterie Roßmann) and with a handful of infantry including troops from the SS-Division “Wiking” between Uman and Slatopol near the town of Swerdlikowo. The Rossman's formation held out for 14 hours against all attacks, thus playing a major role in ensuring the destruction of Soviet 6th, 12th and elements of the 18th Armies. For this action Rossmann received the Knight's Cross on 12 September 1941. Back in Germany, the Flak elements in the Reich took positions in Munich where they contributed to the city's air defence for a short period, before being moved near Paris, remaining there into the spring of 1942. Upgrade to division In May–July 1942 the regiment was expanded to brigade size and renamed Brigade Hermann Göring, under Generalmajor Paul Conrath and during this period undertook general occupation and security duties in France. Brigade order of battle: Stabskompanie (staff company) I.Schützen-Regiment (1-4 infantry companies) II.Schützen-Regiment (5-8 infantry companies, 9th heavy weapons company) III.Schützen-Regiment (10th motorized, 11th armoured engineer and 13th anti-tank companies) Flak-Regiment I.Flak-Abteilung (3 heavy and 3 light batteries) II.Flak-Abteilung (3 heavy, 2 light and 1 howitzer batteries) III.Flak-Abteilung (3 batteries) IV.(Führer) Abteilung (3 batteries, provided Flak cover at Hitler's HQ) Musikkorps Wachbataillon (3 companies) Ersatz-Abteilung In October 1942, when the brigade was still being reformed in Brittany, it was decided to expand the HG to division size, entitled
