After the success of that offensive, clearly visible in the first days (from 13 July), Konstantin Rokossovsky started a serious push westwards in the Lublin-Brest area as well.

Within hours, the front's 2nd Tank Army and several mobile corps began exploiting success to the west with the infantry following in their wake.

The following day, Lieutenant General Semyon Bogdanov's 2nd Tank Army began to advance toward Lublin and the Vistula river, while 11th Tank and 2nd Guards Cavalry Corps spearheaded a northwest push toward Siedlce, with the aim of preventing the retreat of Army Group Center forces which were fighting around the cities of Brest and Bialystok.

[1] A day earlier, on 24 July, Konstantin Rokossovsky’s forces took Lublin and advanced westward towards Vistula, south of the Polish capital of Warsaw.

[2] The Soviet High Command (Stavka) ordered Radzievsky to advance north toward Warsaw as part of the maneuver designed to prevent the retreat of Army Group Centre.

[4] 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.

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).

From 30 July, the Hermann Goering and 19th Panzer Divisions struck the overextended tank corps near Radzymin, north of Wołomin, 15 kilometres northeast of Warsaw.

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.

Lead elements of two Polish divisions from the 1st Army attempted to cross the Vistula into Warsaw on 13 September but made little progress and having sustained heavy casualties were evacuated back across the river ten days later.

The memoirs of General Pavel Batov, 65th Army's commander, describe committing the 44th Guards Rifle Division in an attempt to halt the German advance.
