Joel and Don pretty much nailed it. The Queen Mary is a well known ship of the Cunard Steamship line presently housed as a floating museum in Long Beach, California, where it now serves as a historic hotel and convention facility. During WWII it was painted grey and used as a trans-Atlantic troop transport ship. The vessel sailed from 1936 through 1967, both as a wartime transport carrier and cruise ship. When I was younger, our family took it to the Hawaiian Islands when it was a commercial liner when we moved back there for many years. Ironically, it's only an hour or so drive time from where I now live here in SoCal, proving it's a small world indeed.

The Queen Mary was built in Scotland and first set sail in May 1936. It was named for and launched by Her Majesty Queen Mary amidst great fanfare and celebration. During her more than 30 years at sea, the most celebrated liner of its time hosted A-list celebrities and society figures, sailed more than 1,000 transatlantic crossings and played a pivotal military role between 1940-1946, when she was commissioned to transport military troops during World War II. After carrying more than 765,000 service personnel throughout the conflict, Prime Minister Winston Churchill credited Queen Mary (as well as sister ship Queen Elizabeth) with ending the war one year earlier than estimated. Today, the Queen Mary is one of Southern California's most recognizable icons and continues to educate and entertain visitors from all around the world, offering tours, exceptional exhibitions, a calendar of festivals and numerous social and special events year-round.
Re the Queen Mary in WWII:
War Service: March 1940 - September 1946
War History: Carried a total of 765,429 military personnel. Sailed a total of 569,429 miles (916,407 km). Carried up to 15,000 troops at one time. Carried wounded returning to the United States. Transported Winston Churchill three times to conferences. Carried 12,886 G.I. brides and children.
The records of ships used to carry troops to their theaters of operations were destroyed intentionally in 1951. "According to our [U. S. National Archives] records, in 1951 the Department of the Army destroyed all passenger lists, manifests, logs of vessels, and troop movement files of United States Army Transports for World War II." (Sorry, but there was no word on why the records were destroyed.) Thus there is no longer an official record of who sailed on what ship, though there are still valuable sources that can be found. So this web page is an informal collecting ground for information about troop ship crossings.
