Explanation:

The battle of Gallipoli or battle of the Dardanelles was fought on the Turkish peninsula of Gallipoli in 1915, during the First World War. The campaign is known in Turkey as Çanakkale Savaşlari (Çanakkale War). In the United Kingdom it is called the "Dardanelles Campaign", while in Australia and New Zealand it is known as the "Battle of Gallipoli."

The battle began in February 1915 with a massive bombardment from British and French warships against the strong Ottomans who defended the strait, and who failed mainly due to the mines. This failure promoted between commanders and governments the necessity of a combined operation, in the form of disembarkation, between British and French with the purpose of conquering the Ottoman capital of Constantinople (the present Istanbul). The control of the straits would allow France and the United Kingdom of Great Britain and Ireland to revitalize the Russian Empire and to enclose the central empires. The Russians urgently needed weapons to confront the central empires that made them frontier: the German Empire, the Austro-Hungarian Empire and the Ottoman Empire.

This idea, defended above all by Winston Churchill, would begin with the landing near Gallipoli, but the allies failed to penetrate by surprise into Ottoman territory and failed in the successive offensives, with a result of some 250,000 casualties for each of the two sides.
