 Against the advice of Secretary of Defense Louis Johnson, Secretary of the Navy John L. Sullivan, and Chief of Naval Operations Louis E. Denfeld, Truman ordered "Missouri" to be maintained with the active fleet partly because of his fondness for the battleship and partly because the battleship had been christened by his daughter Margaret Truman.Then the only U.S. battleship in commission, "Missouri" was proceeding seaward on a training mission from Hampton Roads early on 17 January 1950 when she ran aground from Thimble Shoal Light, near Old Point Comfort.She hit shoal water a distance of three ship-lengths from the main channel.
