The Italian objective was to capture these heights, which protected left flank of the Greek position on the Klisura Pass, on the same day.
Following heavy casualties on both sides, the Italian attacks on the 11th Division's sector stopped after that, and were reduced to artillery and air force bombardments and mutual reconnaissance patrol activity.

The division was then assembled in the Metsovo area under I Army Corps command (18 August), and took part in the final storming of the last Communist stronghold at Grammos.
