Private William Mack, 1st/4th ( Border ) Battalion, Kings Own Scottish Borderers. He was killed in action at Gallipoli on 12th July 1915 during the ” Charge ” on the Turkish trenches at Achi Baba Nullah and is commemorated on the Helles Memorial, Helles, Gallipoli, Turkey. He was born in Duns, and had lived and enlisted in Kelso. That day became known as the “Black Day of the Borders” as at evening roll call only 70 unwounded men answered out of the over 700 Officers and men who had begun the attack. Few Borders towns and villages had not lost at least one of their sons that day. The first photo shows Achi Baba marked with a cross. This “hill” dominated the battlefield and was never captured. The second shows the Borderers going over the top and attacking at Gallipoli.
