He is famous for having carried three shells to an artillery piece during the Allied attempt to force the Dardanelles on 18 March 1915.

After serving in the Balkan Wars of 1912–1913, he was transferred to Mecidiye Coastal Battery defending the Mediterranean entrance to Çanakkale.

Corporal Seyit, by himself, is said to have carried three artillery shells each weighing 276 kg to the 240/35 mm gun[1] and enabled it to continue firing on the Allied Fleet.

Following the repulsion of the naval assault, Seyit was promoted to corporal and publicized as an iconic Turkish hero.

A statue of him carrying a shell was erected in 1992, just south of Kilitbahir Castle on the Gelibolu Peninsula.
