The initial attack was successful, and the Austro-Hungarian lines were broken, enabling three of Brusilov's four armies to advance on a wide front (see: Battle of Kostiuchnówka).
Početni napad je bio uspješan i austro-ugarske linije su bile probijene, što je omogućilo da 3 od 4 Brusilovljeve armije napreduju na širokom frontu.
