During the American Civil War the locally mustered 2nd Maine Volunteer Infantry Regiment was the first to march out of Maine in 1861, and played a prominent part in the First Battle of Bull Run.The 1st Maine Heavy Artillery Regiment, mustered in Bangor and commanded by a local merchant, lost more men than any other Union regiment in the war (especially in the Second Battle of Petersburg, 1864). Lying on the Penobscot River, logs could be floated downstream from the Maine North Woods and processed at the city's water-powered sawmills, then shipped from Bangor's port to the Atlantic Ocean 30 miles downstream, and from there to any port in the world.
In 1769 Jacob Buswell founded a settlement at the site.
Today, Bangor's economy is based on services and retail, healthcare, and education.
Founded as Condeskeag Plantation, Bangor was incorporated as a New England town in 1791. Like the possibly eponymous Bangor, Wales, the final syllable is pronounced gor, not ger.
In 1861, the offices of the Democratic newspaper the Bangor Daily Union, were ransacked by a mob, and the presses and other materials thrown into the street and burned.
Editor Marcellus Emery escaped unharmed and it was only after the war that he resumed publishing.
