The Duchess of Bedford and One Woman Who Travelled On It.

The Duchess of Bedford, called "the most bombed ship still afloat", was a very lucky ship. During World War II, she sank a U-boat, damaged another, was shot at and bombed on a number of occassions, and once struck an iceberg without sustaining damage.

From here.

Met a woman last night who sailed as a war bride to Halifax from Southampton on the Duchess of Bedford just a few days after Germany surrendered on May 7th 1945. They still had to travel in convoy formation as not all the German U-Boats had been informed that the war was over. With a round bottom, and no stabilizers so as to travel as fast as possible, her abiding memory was of being sea sick. I didn't ask her age, but her great grandson is 14. The past lives on.

As it was a CP ship, I believe my grandfather would have traveled on it as well.
