The Russian advance collapsed altogether by July 16. On July 19, the Germans and Austro-Hungarians counterattacked, meeting little resistance and advancing through Galicia and Ukraine as far as the Zbruch River. The Russian lines were broken on July 20 and by July 23, the Russians had retreated about (Vinny). "The only limit to the German advance was the lack of the logistical means to occupy more territory".
