This is another key military action of World War I........
THE HISTORY OF THE GALIPOLI CAMPAIGN,
MARCH 1915-JANUARY 1916
The Gallipoli campaign was conceived by members of the War Council of the British Cabinet as a strategy for breaking the trench warfare deadlock on the western front. In August 1914 German troops had invaded France and neutral Belgium and dug in along a line of trench defences for 760 kilometres from the Swiss border to the English Channel. Allied attempts to expel them by frontal assault had failed with heavy losses.
The original idea of a naval attack upon the Turkish defences of the Dardanelles arose in January 1915 after an appeal from Russia to its allies, Britain and France, for assistance against Turkish attacks in the Caucasus. First Lord of the Admiralty; Winston Churchill, searching for alternative theatres of operations and a more aggressive role for the British Navy, proposed a naval 'demonstration' using obsolescent battleships to force the straits of the Dardanelles and subdue Constantinople (present day Istanbul).
