Of the three ships Columbus sailed to the "New World," what were the names of the ships that returned to Spain?

The Niña and Pinta returned to Spain.

The Santa Maria ran aground on Christmas Day, December 25, 1492, and had to be abandoned on the island of Hispaniola. Columbus was received by the native cacique Guacanagari, who gave him permission to leave some of his men behind. Columbus founded the settlement, La Navidad.

While returning to Spain, the Niña and Pinta encountered the roughest storm of their journey, and on the night of 13 February, lost contact with each other. On the Niña, all hands on the Niña vowed, if they were spared, to make a pilgrimage to the nearest church of Our Lady wherever they first made land. On the morning of February 15, land was spotted. These were the Azore Islands. After taking on provisions, Columbus set sail again. Another storm forced him to take port in Lisbon, Portugal.He anchored next to the King's harbor patrol ship on March 4, 1493, where he was told a fleet of 100 caravels had been lost in the storm. Astoundingly, both the Niña and the Pinta had been spared.

After spending more than a week in Portugal, he set sail for Spain. Word of his finding new lands rapidly spread throughout Europe. He reached Barcelona on 15 March, and the Monument a Colom commemorates his arrival. Columbus and his remaining crew came home to a hero's welcome when they returned to Spain.
