Later, as an anti-Bonaparte activist, he was imprisoned in the fortress of Bellegarde and Château d'If then released about 1805 and allowed to come to the United States, settling in Baltimore, Maryland, where he became an instructor in drawing, art and military science at St. Mary's College, the Sulpician Seminary.

[2] By 1808, Godefroy had married Eliza Crawford Anderson, editor of her own periodical, the Observer and the niece of a wealthy Baltimore merchant.

Other projects included the Commercial and Farmers Bank (now demolished), as well as the iron gates and monuments in the burial grounds beneath the Westminster Presbyterian Church (at North Greene and West Fayette Streets), the "sally port" (gatehouse) at Fort McHenry, as well as submitting plans for the 1815 design competition for the Washington Monument to be built in Baltimore.

[3] Godefroy left Baltimore in 1819 for England, his daughter dying of yellow fever before the ship had cleared Chesapeake Bay.

[6] Godefroy designed the famous iconic "Battle Monument" from the recent War of 1812, commemorating the casualties of soldiers and officers from the previous British military attack in the Battle of Baltimore, with the bombardment of Fort McHenry, Battle of North Point, and stand-off at the eastern city fortifications at Loudenschlager's Hill, now Hampstead Hill in Patterson Park, September 12-13-14, 1814, at the old former Baltimore County/Town Courthouse Square on North Calvert Street between East Lexington and East Fayette Streets - constructed 1815 to 1822, and the now landmark First Independent Church of Baltimore, later to become known as the First Unitarian Church of Baltimore (Unitarian and Universalist) at West Franklin and North Charles Streets - 1817.
