On May 7, 1915, the German submarine U-20 torpedoed the British passenger liner Lusitania. Nearly 1,200 people died as a result of its sinking. This tragedy became one of the reasons for the United States' entry into World War I on the side of the Entente.
The Lusitania was launched in 1906. She belonged to the Cunard Line, the transatlantic operator. She was named after the ancient Roman province located on the Iberian Peninsula.
At the time of her commissioning, the Lusitania was the largest ocean liner in the world. Over the course of her life, she broke several records for the fastest crossing of the Atlantic Ocean. In 1909, the liner made her fastest westbound journey, averaging 47.87 km/h.
The British government covered part of the Lusitania's construction costs. Therefore, the United Kingdom had the right to demand the liner's conversion into an auxiliary cruiser if necessary. After the outbreak of World War I, British authorities considered requisitioning the Lusitania for military purposes, but ultimately abandoned the idea due to the ship's high coal consumption.
In April 1915, the liner made another voyage from Liverpool to New York. As the Lusitania prepared to return to Britain, the German embassy in the United States issued a press warning that travel on board could be risky. However, according to historians, many passengers did not believe that the navy of a civilized state would attack a ship carrying civilians.
During the initial stages of World War I, the Entente forces destroyed or captured most of the German surface ships operating in the oceans far from Germany's shores. However, the Germans retained their submarines, and they relied on them to establish a naval blockade of Great Britain.
Moreover, the German naval command believed that it was necessary to sink not only the enemy's military but also its civilian vessels.
On May 1, 1915, the Lusitania left New York and set course for Liverpool. Historians still debate what exactly the ship was carrying. Some researchers have claimed that the civilian ship was supposed to deliver rifle cartridges, shrapnel shell blanks, explosives, and other military supplies to Great Britain, all registered to a fictitious person. However, there is no reliable confirmation of these assumptions.
In early May, Captain William Turner of the Lusitania received a warning from naval command that the German submarine U-20, commanded by Walter Schwieger, had attacked ships off the coast of Ireland. The captain then ordered the watertight doors closed, all portholes sealed, and the number of lookouts doubled. Turner also decided to keep closer to the Irish coast, believing that the submarine posed a far greater threat to the ship in the open sea.
On May 7, 1915, at around 1:00 PM local time, the Lusitania was spotted by one of U-20's sailors. Captain Schwieger examined the liner through his periscope and decided to attack it. According to historians, the encounter between the vessels was accidental: the submarine was already preparing to return to base.
The lookout on the Lusitania spotted the torpedo launched by U-20 moments before it struck the ship's starboard side at 2:10 PM. A powerful explosion followed—and, according to survivors, another one almost immediately after.
The Lusitania listed to starboard, its bow sinking. Attempts to bring the ship to shore were doomed to failure. Panic ensued. Due to the severe list and rapid sinking, only six lifeboats were launched.
At 2:25 PM, the U-20 submarine abandoned the scene of the attack. Three minutes later, the Lusitania sank. This occurred 19 kilometers from the Irish town of Kinsale.
Vessels flying British, American, and Greek flags began arriving at the scene of the liner's sinking. Their crews rescued those still in the water. Irish fishermen also rushed to the aid of the Lusitania's passengers and crew.
There were approximately 1,960 passengers and crew members on board the Lusitania, of whom 1,198 died, including approximately 100 children. The bodies of approximately half of the victims were never recovered. The incident became one of the largest maritime disasters of the early 20th century.
Many civilians died. No belligerent power had ever done anything like this before. It was the greatest war crime committed by submariners during World War I.
Captain Turner remained on the Lusitania until the very end. During the sinking, he was swept overboard by a wave, but he survived for about three hours and was rescued by Irish fishermen.
The second explosion on the Lusitania continues to be the subject of heated debate. The British claimed that U-20 actually fired two torpedoes, but the Germans denied this, claiming that ammunition detonated on the ship. Modern researchers speculate that coal dust may have been the cause.
Historians believe that by attacking the Lusitania, the German sailors primarily harmed their own country. The mass loss of civilian life shocked the international community, with the Allied powers doing everything possible to draw maximum attention to the tragedy.
Approximately one in ten of those killed in the disaster was an American citizen. And the public reaction in the United States to the incident was extremely painful.
