USS Constitution. Launched in Boston in 1797, the oldest commissioned warship afloat earned her nickname Old Ironsides during the War of 1812 when she fought the British frigate HMS Guerriere. During this historic battle, cannonballs fired at USS Constitution appeared to bounce off, causing one of her crew to remark that her sides were made of iron.
How USS Constitution Became âOld Ironsidesâ. Britannia ruled the waves at the onset of the War of 1812. When the British frigate HMS Guerriere dueled USS Constitution in the warâs first major naval engagement, the outcome was swift, decisive and surprising. In less than an hour of fierce fighting, Guerriere was in tatters and Constitution had been transformed into an American icon: âOld Ironsides.â. Around 2 p.m. on the afternoon of August 19, 1812, a lookout aboard USS Constitution spied a sail against the cloudy southern horizon.
