"Andrea Doria" sank in the night between July 25, 1956, and July 26, 1956. When she sank, she had 1,134 passengers and 572 crew members, and her captain was Piero Calamai. She was sailing in the Atlantic Ocean. Her path was from Genoa, Italy, to New York, in the United States. "Andrea Doria" entered very thick fog when it passed by Nantucket, which is a small island near Massachusetts. Soon, another ship entered the fog. This was SS "Stockholm". SS "Stockholm" was another passenger ship. Because of the fog, the two ships could not see each other. When they finally noticed each other, they tried to turn away. "Andrea Doria" turned left to pass "Stockholm". But "Stockholm" turned right to try to pass "Andrea Doria". Because of the fog, they could not see what each other was trying to do. At 11:10 PM of July 25, 1956, "Andrea Doria" and "Stockholm" crashed together.
