Charalambos Pettemeridis finished the primary school of his village and first worked as a bank teller in Kyrenia and later as a grocer in Amiantos. He joined EOKA with the beginning of the Struggle, while he was in Kyrenia, where he worked in 1955, and continued his activity in the area of ​​Pitsilia-Spilion-Amianto. His action continued with close cooperation with the insurgents of the area, whom he hosted in his house, where he built a hideout. 
In June 1958, he was arrested for treason and held for thirty-five days in Platra’s interrogation room. After his dismissal, he built a hideout on the mountain opposite his village, with a wanted comrade, in which other rebels also lived.

On October 6, 1958, he set up an ambush against the British with the rebels of their group in the location of Moutti of Saradi, between the villages of Spilia and Lagoudera. They placed a mine on the road, which they had connected to a mortar that they fixed to a tree, so that the explosion of the mine would hit the British car, while the explosion of the mortar would immobilize any cars that would follow it. The insurgents numbered four and had, in addition to the mine and mortar, a pistol, a Bren gun, an M3 automatic weapon and grenades. During their attack, two cars full of soldiers were hit, and they approached the ambush site with their lights off. During the retreat, Charalambos Pettemeridis was fatally beaten while crossing the road by soldiers from a third car, which was also approaching with its lights off.

At his funeral his wife sang her improvised lyrics, praising her Levantine husband, before she passed out in her father’s arms. She later continued her bid for the race until the end.
