Although the Russian troops at certain moments of the battles lacked artillery shells (while the consumption of shells was the highest since the beginning of the war), they were well equipped with rifle cartridges and retained an advantage in the number of machine guns. Skillfully directed fire from hand weapons was very effective, and massive frontal assaults cost the victorious troops dearly, which was reflected in the gradual narrowing of the breakthrough front.

For 10 weeks, the Russian armies of the Southwestern Front and the left flank of the armies of the Northwestern Front were thrown back in Galicia - across the Bug, Zlota Lipa and Dniester rivers, retaining only a small part of the Austria-Hungary’s territory, and in the Kingdom of Poland they retreated beyond the Vistula to Józefów , across the Tanew River, to Krasnystaw and Hrubieszów - approximately
