The Mansfield House, home of the Middlesex Historical Society, was General Mansfield's home. The Society's Civil War Day last month reenacted the fall of 1862, when Mansfield was killed in the battle of Antietam.
Our pages have so frequently borne testimony to his services that it is needless to recapitulate them. He commanded a division of the Union army during the eventful Peninsula campaign, and was killed at the bloody fight at Sharpsburg, on Wednesday, 17th Sept., while gallantly leading his men on to the charge. A presentiment of his approaching fate had been over him for some time, for, dining with Eli Thayer only 1 days before the battle, but just before taking leave seemed abstracted, and, after a few moments silence, said, "Mr. Thayer, I am going into battle. If I fall, have my body sent to my friends at Middletown, Conn." He left immediately after making the request.
