A preliminary attack was launched in February 1915, bombarding the artillery of the Ottoman Empire. On March 18, Allied ships attempted to navigate the strait. Allied ships engaged Turkish artillery battleships on the shore while Allied minesweepers attempted to clear a pathway into the strait. However, the minesweepers pulled back under intense Turkish fire, leaving the Allied battleships vulnerable to mines, which sunk two ships and left several others badly damaged. | A preliminary attack was launched in February 1915, bombarding the artillery of the Ottoman Empire.
