My Lords, I share the gratefulness of the House to the noble Lord, Lord Harris, for introducing this short debate with some expert knowledge. He seemed surprised that the Liberty ship was built in 137 days. One of them was actually built in four days. Although they were built to last for only one voyage across the Atlantic, after the war many of these Liberty ships went on to work for the Greeks and other nations for some 20 years. They were not quite as rough as they were made out to be. I must say to the noble Lord, Lord Patten, that I had the great pleasure of sailing across to Dunkirk in the “Sundowner” in 1990 on the 50th anniversary of the Dunkirk evacuation.
