1st Belorussian Front  The 1st Belorussian Front" (Russian: Пéрвый Белорусский фронт", alternative spellings are 1st Byelorussian Front) was a major formation of the Soviet Army during World War II, being equivalent to a Western army group. Initially, the Belorussian Front was created on 20 October 1943 as the new designation of the existing Central Front. It was placed under the command of General Konstantin K. Rokossovsky, who had been commanding the Central Front. It launched the Gomel-Rechitsa Offensive in 1943 and then the Kalinkovichi-Mozyr Offensive in 1944. It was then renamed the 1st Belorussian Front (1BF) on 17 February 1944 following the Dnieper–Carpathian Offensive. A few days later, on 21 February, the Rogachev-Zhlobin Offensive commenced, which continued until 26 February. The next operation was the Bobruysk Offensive, part of Operation Bagration, and on 26 June the attacks of 1BF encircled Bobruisk, trapping 40,000 troops of the German 41st Panzer Corps (part of 9th Army). From 18 July-2 August the Front was part of the Lublin-Brest Offensive. From 2 August to 30 September, the Front was engaged cleaning out Germans to the east of the Vistula (during which the Battle of Radzymin took place from 1–10 August). Its 8th Guards, 28th, 47th, 65th, 69th, and 70th Armies were involved at Radzymin. Later during that same period, on 14 September, 1BF with the support of Polish forces it captured Praga, a suburb of Warsaw. The next attack was the Warsaw-Poznań Operation, a part of the Vistula-Oder Offensive. On 13 January, 1BF began an offensive toward Pillkallen (Schlossberg between 1938–1945) in East Prussia, against which they met stiff resistance from the 3rd Panzer Army. The 1st Belorussian Front opened its attack on the German Ninth Army from the Magnuszew and Puławy bridgeheads at 08:30 on 14 January, again commencing with a heavy bombardment. The 33rd and 69th Armies broke out of the Puławy bridgehead to a depth of 30 km, while the 5th Shock and 8th Guards Armies broke out of the Magnuszew bridgehead.
