The Northeast Coast campaign (1745) occurred during King George's War from 19 July until 5 September 1745. Three weeks after the British Siege of Louisbourg (1745), the Wabanaki Confederacy of Acadia retaliated by attacking New England settlements along the coast of present-day Maine below the Kennebec River, the former border of Acadia. They attacked English settlements on the coast of present-day Maine between Berwick and St. Georges (Thomaston, Maine), within two months there were 11 raids - every town on the frontier had been attacked. Casco (also known as Falmouth and Portland) was the principal settlement.
