Unaware of the Ottoman retreat the Greeks failed to use the opportunity and cut their access to the bridge across the Haliacmon. Upon reaching their second defensive line, the Ottomans became aware of the 4th Divisions' seizure of Porta Pass, panic spread in their ranks and many soldiers began fleeing and abandoning their equipment.[18] On the morning of 10 October, the 4th Division charged down the northern slope of the Rahovo Mountain, surprising the Ottoman infantry and artillerymen who abandoned over twenty Krupp guns and engaged in a disorganized retreat.[19][2] The Greek cavalry's indecision once again enabled the fleeing Ottomans to safely reach Servia and Kozani.[20]
