Hüseyin Avni Bey was born in Manastir, Ottoman Empire (in the present day Bitola, North Macedonia) in 1875.
The regiment was assigned to the 19th Division which was being raised by Lieutenant Colonel Mustafa Kemal (who was ten years longer than Avni).
[2] The regiment was training at Rodosto when in response to the perceived threats to the Dardanelles the III Corps of which the 19th Division was part was assigned the task of reinforcing the Gallipoli Peninsula.
In the time which passes until we die, other troops and commanders can take our place” Avni led his regiment in an action during which it sustained heavy losses but were able to successfully stabilize the right flank of the Turkish defences.
[3] In Kemal's subsequent war report on the battle he describes Avni as a kind-hearted, faithful and highly esteemed commander.
[1] Hüseyin Avni left behind his wife Fatma Zehra's as well as a young son Tekin (Mehmet Fehmi) and daughter Melek.
Finally in 1955, he found the burial site, which was identified by a rusted tinplate bearing the words, "Commander of the 57th Regiment, Avni".
It is enclosed by an iron fence and bears the inscription in Turkish “Hero 57th Infantry Regiment Commander Lieutenant Hüseyin Avni, son of Ali, Manastir (Bitola).
Also present underneath a Turkish flag is a plaque that bears a longer description, dedicated to the dead of the 57th regiment and listing its achievements.
