wiki: RMS Balticwas an ocean liner of the White Star Line that sailed between 1904 and 1933. At 23,876 gross tons, she was the largest ship in the world until 1905. She was launched on 21 November 1903 by Harland and Wolff at Belfast and sailed from Liverpool on her maiden voyage to New York on 29 June 1904.
On 14 April 1912, the Baltic sent an ice warning message to the RMS Titanic:
“Greek steamer Athenia reports passing icebergs and large quantities of field ice today in latitude 41° 51’ N, longitude 49° 52’ W. Wish you and Titanic all success. Commander.”
