During World War I, she served in the Ottoman navy, first as a minesweeper and then as a coastguard vessel.

After the end of the war, in which the Ottoman Empire was defeated, she anchored in Karadeniz Ereğli, a port on the western Black Sea.

On 17 July 1921 during her ninth voyage, while carrying two British made 88 mm guns and 354 ammunition boxes from Batumi, she was spotted by two Greek warships.

The citizens of Ordu helped to unload the artillery before the Greek ship showed up and the captain Mahmut, who later adopted the surname Gökbora, shipwrecked Rüsumat.

The Greek torpedo boat Dafni arrived; but seeing the fire they quickly left Ordu.
