In 1840, Samuel Cunard, a war veteran and timber merchant from Halifax, Nova Scotia, established the Cunard line. His ships were steam powered ferries - the first in the area - and over the next few years Cunard branched out to ocean steam, providing a mail service to Prince Edward Island, along the coast and, later, across the Atlantic.
Cows were kept on board for fresh milk every day, and were slaughtered to be eaten on the final day of each voyage. During the 1840s, Charles Dickens sailed with Cunard to Boston, and the first Cunard Transatlantic Crossing took place when Britannia set sail in July 1840.
