According to historians and Ottoman documents, about 33,000 Albanians participated in the Battle of Canakkale (Gallipoli) in 1915. The vast majority of them were muhajirs and Albanians who had migrated to Anatolia after the conquests of Albanian territories in the Balkan Wars.
The dimensions of Albanian participation and contribution to this battle include:
Mobilization: Approximately 33,000 Albanians joined the ranks of the Ottoman army, who responded to the call for mobilization.
Casualties: Of this contingent of fighters, it is estimated that around 20,000 to 25,000 Albanians fell as martyrs (martyrs) in the defense of the Çanakkale Strait.

Composition: In addition to forces recruited from Albanian communities in Turkey, thousands of volunteers and soldiers who had migrated from ethnic territories such as Polog and other occupied areas also participated in the battle.

According to Ottoman sources, how many Albanians participated in the Battle of Çanakkale (Gallipoli)?
There is no direct data in the Ottoman archives on the exact number of Albanian soldiers who took part in the Gallipoli campaign. However, various sources and studies indicate that Albanians made a significant contribution to this war.
Some sources claim that around 25,000 Albanians participated in the Gallipoli campaign, of whom 10,000 fell as martyrs and 5,000 went missing.
On the other hand, another source states that only 27 people from Albania fell as martyrs.
These discrepancies may be due to the lack of precise documentation on the ethnic origin of participants, caused by shortcomings in record-keeping methods of the period and the multi-ethnic nature of the Ottoman army.
In addition, it is said that the number of volunteers from the Rumelia region who joined the Ottoman army during World War I was over 50,000.
This information shows that the role of Albanians in the Battle of Gallipoli was significant, although there are differences regarding the exact numbers.
