The cavalry brigade moved on the extreme west along the road towards Servia, planning to block the bridge across the Haliacmon.[15] Attacking from the east of the pass the Konstantinopoulos Evzone detachment overcame stiff resistance at Vlacholeivado and captured the village, but failing to advance further due to heavy fog.[16][14] At 2 p.m., the main bulk of the Greek artillery was brought to the main line, joining the engagement. Despite suffering heavy casualties, the three divisions had halted some 500–700 metres (0.31–0.43 mi) from the Ottoman trenches intending to launch a final assault the following morning.[14]
