Question: How many miles long is the canal where the battleship was transferred to in December? Passage:After the beginning of World War I in August 1914, Swiftsure escorted troop convoys in the Indian Ocean until she was transferred to the Suez Canal Patrol in December. After defending the Canal in early 1915 from Ottoman attacks, the ship was then transferred to the Dardanelles in February and saw action in the Dardanelles Campaign bombarding Ottoman fortifications. Triumph participated in the hunt for the German East Asia Squadron of Maximilian Graf von Spee and in the campaign against the German colony at Tsingtao, China. The ship was transferred to the Mediterranean in early 1915 to participate in the Dardanelles Campaign. She was torpedoed and sunk off Gaba Tepe by the German submarine on 25 May 1915.
