 The 19th and "Hermann Göring" Panzer Divisions mounted several assaults during early August, but the Soviet lines remained firm, managing to retain their positions on the other shore; they would prove crucial during the upcoming Vistula-Oder Offensive that would cross central and western Poland and aim to bring the Soviets within the reach of Berlin.Further battles of that period included the battle of Studzianki.During the offensive bringing the 1st Belorussian Front’s left wing closer to the Vistula River, the Polish Home Army ("Armia Krajowa") staged an insurrection in Warsaw; the Soviet advance was one of the factors which accelerated the Uprising, as the Poles both counted on Soviet support and wanted to secure their capital independently (as part of the Operation Tempest).
