The USS Constitution was recommissioned on 1 July 1931 under the command of Louis J. Gulliver with a crew of 60 officers and sailors, 15 Marines, and a pet monkey named Rosie as their mascot. The tour began at Portsmouth, New Hampshire, with much celebration and a 21-gun salute, scheduled to visit 90 port cities along the Atlantic, Gulf, and Pacific coasts. Due to the heavy itinerary, she was towed by the minesweeper Grebe. She went as far north as Bar Harbor, Maine, south and into the Gulf of Mexico, then through the Panama Canal Zone, and north again to Bellingham, Washington, on the Pacific Coast. Constitution returned to her home port of Boston in May 1934 after more than 4.6 million people visited her during the three-year tour
