Final answer:
The Gallipoli campaign took place in modern-day Turkey and involved a constant stalemate between Allied forces and Ottoman defenses. It was neither part of the Western nor the Eastern Front, but rather an unsuccessful attempt to open up a new front against Austria-Hungary and Germany during World War I.
Step-by-step explanation:
The Gallipoli campaign was a significant military engagement during World War I that took place in modern-day Turkey. The operation, which was a concept of Winston Churchill, aimed to open a third front against Austria-Hungary and Germany and facilitate coordination with Russian forces by seizing the Dardanelles Strait. In 1915, Allied troops, including the Australian and New Zealand Army Corps (ANZAC), landed on the Gallipoli Peninsula but faced stout defenses by the Ottoman forces led by Mustafa Kemal Atatürk. The campaign was characterized by a constant stalemate, with neither side able to gain a decisive advantage and resulting in heavy casualties.
The Gallipoli campaign was not part of the Western Front or the Eastern Front, which were the main battle lines in Western Europe and Eastern Europe, respectively. Instead, the campaign was an attempt by the Allied forces to break the deadlock of trench warfare prevalent on those fronts by opening up a new front through the Ottoman Empire. Despite months of fighting, the campaign ultimately ended in failure for the Allied forces and was considered one of the greatest disasters of the war.
