On the second day of the operation, the HV 1st Guards Corps and the 3rd Battalion of the 1st Guards Brigade outflanked the VRS mountaintop position between the Šator Mountain and Glamoč that had blocked them the previous day, allowing the HV 81st Guards Battalion to advance a further and threaten to interdict a road used by the VRS to supply Glamoč from the north. To secure the high ground south of Glamoč, Gotovina released the 1st Battalion of the HV 1st Guards Brigade, supported by an anti-terrorist unit of the HV 72nd Military Police Battalion, from the reserve and used them to attack VRS positions on the Vrhovi Mountain. The HVO units continued their attack towards Glamoč, achieving little progress. The HVO 2nd Guards Brigade only advanced towards Glamoč. By the end of its second day, Operation Summer '95 was suffering from delays.
