Gwin 67kWilliam Gwin was born on 6 December 1832 in Columbus, Indiana. He entered U.S. Navy service as a Midshipman in April 1847, subsequently serving in the frigate Brandywine on the Brazil Squadron until late in 1850. During the next five years he was assigned to the sloop of war Germantown, flagship of the African Squadron, the steamer Princeton and the brig Bainbridge. In September 1855, while serving in the latter, he was promoted to the rank of Lieutenant. From late 1857 until after the outbreak of the American Civil War in the spring of 1861, Gwin was an officer of the steamer Saranac and sloop of war Vandalia, both in the Pacific, and of the steam frigate Susquehanna in the Mediterranean. Returning to the United States in mid-1861, Lieutenant Gwin began Civil War combat service in the newly acquired cruiser Cambridge and, later in the year, was assigned to the brig Perry. Early in 1862 he went west to begin a very active period on the Mississippi River and its tributaries, initially as Commanding Officer of the gunboat Tyler, which played a significant role in several combat actions between February and July. Promoted to Lieutenant Commander in July, Gwin commanded the ironclad Mound City during much of the summer and in September took command of the big ironclad Benton. On 27 December 1862, in a heated engagement with Confederate artillery on the Yazoo River, his ship was seriously damaged and Gwin mortally wounded. Lieutenant Commander William Gwin died on 3 January 1863. In reporting his death to the Navy Department, Gwin's squadron commander, Rear Admiral David Dixon Porter, remarked: "The country has lost one of its bravest officers."
