The 1st Division then marched toward Sarantaporo, arriving in the area on the night of 8 October 1912. The Ottoman VIII Corps, ordered to halt the Greek Army's advance north, had retreated and regrouped around the town. On 9 October 1912, during the Battle of Sarantaporo, the 1st Infantry Division, along with the 2nd and 3rd divisions, began a full frontal assault on Turkish positions. Withstanding heavy casualties during their advance, primarily due to accurate Turkish artillery barrage, the 1st Division managed to capture a shoulder and two nearby hillocks. On the division's right wing, the Konstantinopoulos Evzone Detachment (Απόσπασμα Ευζώνων Κωνσταντινόπουλου "Apospasma Evzonon Konstadinopoulou") was able to advance and capture Turkish positions at Livadi. The Greek 4th Infantry Division, in the meantime, had broken through Turkish lines on the western flank and captured the Porta Pass. On the night of 9 October 1912 Turkish forces, taking advantage of the bad weather, retreated and escaped encirclement. A Turkish battalion remained, facing the Konstantinopoulos Detachment's positions at Livadi, oblivious to their comrades' retreat. On the morning of 10 October 1912, the Evzones attacked the Turks, forcing them to retreat to Neochori.
