Havre de Grace in Harford County, Maryland — The American Northeast (Mid-Atlantic)
Hero's Reward
Star-Spangled Banner National Historic Trail
John O'Neill led a futile defense when British raiders attacked Havre de Grace May 3, 1813. As other defenders fled, O'Neill briefly manned a cannon alone.
His courage earned O'Neill a presidential appointment as first keeper of the Concord Point Lighthouse. He lived here from 1827 until his death in 1838.
" An English officer on horseback followed by the marines, rode up and took me with two muskets in my hand." -- John O'Neill, Baltimore Niles' Weekly Register May 15, 1813.
Tributes
O'Neill's bravery was rare among hometown defenders. He was honored in 1813 with a sword inscribed "to the Gallant O'Neill for his valor at Havre de Grace." A century later, the town dedicated the John ONeill Cannon Memorial to this local hero.

where
John O'Neill
1769-1838
served the guns single handed during the
British attack upon Havre de Grace
May 3, 1813 until disabled and captured.

As a tribute to the gallant conduct of her father, the citizens of Philadelphia presented to him a handsome sword.
