As there were too few lifeboats, and a policy of women and children first was in action, many just stayed behind and faced their inevitable fate. Also, the band aboard chose to continue playing music while it sunk
He was the master, or captain, of the RMS Carpathia on 15 April 1912, which is the ship that rescued some of the passengers from the sinking RMS Titanic.
People thought that Titanic was beautiful and such a luxurious ship. They also thought that Titanic would be unsinkable, even when the passengers were told that the ship was sinking, some didn't believe.
Sinking
It was an enemy ship and it was carrying munitions. When it was hit by a torpedo, some of those munitions are thought to have exploded causing more damage and hastening the sinking of the ship.
I think "rats" is likely to mean "coward" who run away when they have a problem. If some one, or some people run when difficulties arise, or when things get bad, they are compared to rats deserting a sinking ship. The rats only care for their own safety, and will not stay to help prevent the ship from sinking or to help others
The U.S., in part, entered World War I due to the sinking of the Lusitania by a German U-Boat. Some of the Lusitania's passengers were American citizens.
Eventually ALL of Titanic's passengers knew she was sinking (except for one girl in the lifeboats who didn't speak English). However, the water breaching through the hull entered for ten minutes before she started to tip.
To get on a ship, you typically use a gangway or boarding ramp, which provides a safe walkway from the dock to the ship. Passengers may also use stairs or ladders if the ship is docked at a lower level. In some cases, smaller boats or tenders are employed to ferry passengers to and from the ship when it's anchored offshore.
Taking on water is what starts a ship sinking. What causes the water to get in can be anything from a broken pipe, a breach in the hull, water coming over the hull and entering through hatches, or some catastrophic event such as an explosion.
The British report lists 2201 people as passengers, but some of the lists show people that were not on the ship and names of people who were on the ship are missing.
The Birkenhead, a British troopship that sank in 1852, primarily carried soldiers, their families, and crew members. Most of the passengers were soldiers from the 12th Regiment of Foot, along with some women and children. The ship was transporting these individuals to the Cape of Good Hope in South Africa for military service. The tragic sinking highlighted the courage of those on board, as many men sacrificed themselves to ensure the safety of women and children during the evacuation.
On the Titanic, there were not enough lifeboats to accommodate all passengers and crew; the ship carried 20 lifeboats, which could hold about 1,178 people, while over 2,200 were on board. This left a significant number of individuals without space in the lifeboats during the evacuation. Many lifeboats were launched partially filled, as there was confusion and chaos during the sinking, and some people were hesitant to leave the ship. Ultimately, a considerable amount of lifeboat capacity went unused due to these circumstances.
