[2] For more than half a century Mihailović welcomed and sent off the descendants of Serbian soldiers who died on the Salonika front during the First World War.

The first keeper of the graveyard was Đorđe's grandfather, Serbian military volunteer Savo Mihailović, a Serb from Grbalj, near Boka Kotorska.

Savo collected the bodies of his dead friends and comrades, and then protected and guarded the cemetery until his death in 1928.

The duty to guard the cemetery was given to Đorđe, the last male descendant of the Mihailović line.

[5] Raša Perić dedicated a song to the keeper of Zeitenlik, Đorđe Mihailović: "Marching all night".
