On July 14, 1906, groups of Macedonian fighters led by captains Evangelos Nikoloudis and Ioannis Karavitis went to Gornitsovo to attack the Bulgarian band of Chief Tane, who was stationed in the village. Their guide was a local, Grigorios Sapountzis, a Macedonian fighter and director of the "Center of Florina". In the early hours of July 15, Nikoloudis, accompanied by ten men and Sapountzis, entered the village from the southwest and headed toward the church to locate Tane’s Bulgarians. Two small groups of six men each were sent to the west and east of the village to prevent the Exarchists from escaping. Ioannis Karavitis’ group remained in the south for the same reason.

However, when Nikoloudis’ men arrived in the village, Ottoman troops, who had been informed of the attack plan and were lurking on the northern side, surrounded the Macedonian fighters. At the same time, other Ottoman detachments attacked the groups stationed outside the village. Under these circumstances, the Greek Macedonian fighters led by Ioannis Karavitis retreated to the west of the village and managed to escape to the Piperitsa hill and then to Morihovo. A total of twelve (12) Macedonian fighters, including Captain Evangelos Nikoloudis, lost their lives in the battle of Gornitsovo. It was later revealed that the plans for the attack on Gornitsovo had been betrayed to the Ottoman authorities by Grigorios Sapountzis, who boasted to an Ottoman that he would go to Gornitsovo and set it on fire. Sapountzis was captured in the battle of Gornitsovo and taken to the monastery prison, from which he later escaped.
