Which ship was first to arrive on the disaster scene and rescue survivors of the Titanic?

At sea all Mariners will come to the aid of the distressed, no matter what the risk they go. There are no borders at sea when it comes to rescue.

The unsinkable Molly Brown was rescued by the Carpathia

you hardly ever hear of the epic efforts of the Carpathian crew in saving so many stricken people.

A lot of mistakes were made that led to the tragic sinking of the Titantic!

for a great story about the titanic, look for "a night to remember" also a movie by the same name.
