 Till 20 August, the 47th Army remained the only major Red Army unit in the vicinity of Warsaw.The Soviets made no attempt to aid the uprising, concentrating on securing Soviet positions east of the river, not providing the insurgents even with artillery support.At the time, the bulk of the 1st Belorussian Front’s centre and right wing were struggling to overcome German defences north of Siedlce on the approaches to the Narew River and, according to Soviet accounts, were unable to support any action to aid Warsaw directly.
