The RMS Titanic picked up passengers from three ports before its maiden voyage. Which port did it not stop at to pick up passengers?

RMS Titanic (/taɪˈtænɪk/) was a British passenger liner that sank in the North Atlantic Ocean in the early morning hours of 15 April 1912, after it collided with an iceberg during its maiden voyage from Southampton to New York City. There were an estimated 2,224 passengers and crew aboard the ship, and more than 1,500 died, making it one of the deadliest commercial peacetime maritime disasters in modern history.

After leaving Southampton on 10 April 1912, RMS Titanic called at Cherbourg in France and Queenstown (now Cobh) in Ireland before heading west to New York. On 14 April, four days into the crossing and about 375 miles (600 km) south of Newfoundland, she hit an iceberg at 11:40 p.m. ship's time. The collision caused the ship's hull plates to buckle inwards along her starboard (right) side and opened five of her sixteen watertight compartments to the sea; she could only survive four flooding. Meanwhile, passengers and some crew members were evacuated in lifeboats, many of which were launched only partially loaded. A disproportionate number of men were left aboard because of a "women and children first" protocol for loading lifeboats. At 2:20 a.m., she broke apart and foundered—with well over one thousand people still aboard. Just under two hours after the Titanic sank, the Cunard liner RMS Carpathia arrived at the scene, where she brought aboard an estimated 705 survivors.
