RMS Lusitania was identified and torpedoed by the German U-boat U-20. She took on a heavy starboard list, and sank in 18 minutes. The vessel went down 11 miles (18 km) off the Old Head of Kinsale, Ireland, killing 1,198 and leaving 761 survivors. The sinking turned public opinion in many countries against Germany, contributed to the American entry into World War I and became an iconic symbol in military recruiting campaigns of why the war was being fought.
