Augusta is the capital of the US state of Maine, county seat of Kennebec County, and center of population for Maine. Located on the Kennebec River at the head of tide, it is home to the University of Maine at Augusta. A hotbed of Abenaki hostility toward British settlements was located further up the Kennebec at Norridgewock. In 1722, the tribe and its allies attacked Fort Richmond (now Richmond) and destroyed Brunswick. In response, Norridgewock was sacked in 1724 during Dummer's War, when English forces gained tentative control of the Kennebec. In 1754, a blockhouse named Fort Western (now the oldest wooden fort in America), was built at Cushnoc on the eastern bank. It was intended as a supply depot for Fort Halifax upriver, as well as to protect its own region. In 1775, Benedict Arnold and his 1,100 troops would use Fort Western as a staging area before continuing their journey up the Kennebec to the Battle of Quebec.
