These two bullets were found after the Battle of Gallipoli which started in 1915 and ended in 1916 during WWI.
The allies consisted of British, French, Australia and New Zealand against a fierce Turkish Army. In the end, the allied side lost 46,000 troops while the Turkish lost 65,000, with the Allies retreating from the battle.
The Turks still consider their victory at Gallipoli to be a great, defining moment in the nation’s modern history. Eight years later, the Turkish War of Independence broke out, led by Mustafa Kemal Ataturk. Ataturk was a commander at the battle of Gallipoli.
The battle was also Australia and New Zealand’s first military campaign as independent dominions in the British Empire. It was a formative moment in the national consciousness of both countries.
