Halil Sami Bey (1866 – 1925) was an Ottoman Army colonel, who served in the First World War.

The 10th Company, with the heroic efforts of Yahya Çavuş who fought against 3000 British infantry with one squad under his command, was totally wiped out with all the other Turkish forces defending the beaches.

After the 25th, the battle turned into continuous trench warfare with the British and French forces not being able to reach Altçıtepe, a crucial hill which would open the way to the capturing of the Gallipoli peninsula from the south.

The Kirte and Zigindere battles inflicted heavy casualties on both sides with the majority dead being the Turkish defenders.

He later participated in the Turkish War of Independence where he joined the forces of Mustafa Kemal Pasha and fought against the invading Greek, British and French armies.
