From The Miami News on this day in 1945:
PET DEPT.: The 15,000 troops who arrived on the Queen Mary were warned, before boarding the ship, that no dogs would be permitted aboard because of the quarantine regulations. Then, during the crossing, the ship's steward noticed a dachshund in one of the lounges. He followed it and found seven other dogs--an airdale and six mongrels...These eight dogs eventually were turned over to the ASPCA, but not before Captain Illingsworth, skipper of the Queen Mary, had told the ship's doctor to destroy them, and the man replied: "Captain, I am a doctor, not an executioner."
