full_context: Document 1: Fort Pownall: Fort Pownall was a British fortification built during the French and Indian War, whose remains are located at Fort Point State Park in Stockton Springs, Maine. The fort was named for Governor Thomas Pownall, who oversaw its construction.

The fort's remains were listed on the National Register of Historic Places in 1969.
Document 2: Fort Chiswell Site: Fort Chiswell Site is a historic archaeological site located at Fort Chiswell, Wythe County, Virginia. It is the site of a frontier fort built in 1758 as an outpost during the French and Indian War. The fort was situated at the junction of the Great Trading Path and the Richmond Road, near the New River. The fort fell into disrepair in the 18th century as both the county seat and courthouse were moved from Fort Chiswell to the county seat of Wytheville, 12 miles to the west. The remaining foundations of the Fort and its surrounding buildings were completely covered over during the construction of I-77 in Wythe County during the 1970s. There is a pyramid shaped historical marker of sandstone situated approximately 200 yards west-northwest of the fort's original location next to the old chicken house.
Document 3: Cherokee: The Cherokee ( ; Cherokee: ᎠᏂᏴᏫᏯ , "Aniyvwiyaʔi " or Cherokee: ᏣᎳᎩ , "Tsalagi " ) are an indigenous people of the Southeastern Woodlands. Prior to the 18th century, they were concentrated in southwestern North Carolina, southeastern Tennessee, and the tips of western South Carolina and northeastern Georgia. The Cherokee language is a Southern Iroquoian language and part of the Iroquoian language family. Today there are three federally recognized Cherokee tribes: the Eastern Band of Cherokee Indians in North Carolina, the United Keetoowah Band of Cherokee Indians in Oklahoma, and the Cherokee Nation in Oklahoma.
Document 4: Redstone Old Fort: Redstone Old Fort — or Redstone Fort or (for a short time when built) Fort Burd — on the Nemacolin Trail, was the name of the French and Indian War-era wooden fort built in 1759 by Virginia militia colonel James Burd to guard the ancient Indian trail's river ford on a mound overlooking the eastern shore of the Monongahela River (colloquially, just "the Mon") in what is now Fayette County, Pennsylvania near, or (more likely) on the banks of Dunlap's Creek at the confluence. The site is unlikely to be the same as an earlier fort the French document as Hangard dated to 1754 and which was confusedly, likely located on the nearby stream called Redstone Creek. Red sandstones predominate the deposited rock column of the entire region.

Document 6: Savannah Town, South Carolina: Savannah Town, South Carolina is a defunct settlement that was located in the colonial years on the Savannah River below the fall line in present-day Aiken County. In the 1670s the Westo had a village here, but they were displaced by the Savannah (as the English called a local Shawnee band) in a trade war, and it became known by 1685 as Savannah Town. The English colony had traders who did a lucrative business in dressed skins with the Savannah Shawnee. Fortified as a frontier post, the settlement developed and ferry service was established across the river. The town was gradually overtaken by its competitor of Augusta, Georgia, established in 1735 five miles upriver and closer to Indian settlements. Traders here intercepted commerce, sending it to their port of Savannah on the coast. By 1740 Savannah Town was declining, and by 1765 the village was abandoned and the fort closed.
Document 7: Acolapissa: The Acolapissa were a small tribe of Native Americans. Traditions have them living on the shores of the Pearl River, between Louisiana and Mississippi before 1702. This made them one of four tribes, along with the Bayogoula, Biloxi, and Pascagoula who inhabited the Gulf coast of what is now the state of Mississippi at the time of the European arrival. After that time, they moved farther west, into the area around the future New Orleans. Pressured by European settlement of the area and disease, the small tribe eventually merged into the Houma, which now live in and around Houma, Louisiana. Estimates put the current population of the Houma tribe at around 11,000 people. The U.S. government denied a petition for Federal status for the Houma in 1994.

Document 14: Fort Anderson (North Carolina): Fort Anderson is a mid 19th century earthen fort in the lower Cape Fear Region of North Carolina, located over the ruins of the colonial town of Brunswick in Brunswick County. It was used as a Confederate Fort during the American Civil War. The fort was pivotal in protecting the Cape Fear River inlets and Wilmington upstream. Earthen batteries comprise the fort and were used as platforms and shields for the Confederate cannons. Beneath some of the earthworks were "bombproofs," shelters used by troops during enemy bombardment. The Confederacy decided to build forts around the Cape Fear River to protect the port of Wilmington from the Union blockade. During the Civil War, blockade runners brought supplies such as iron, guns, and ammunition to the Confederacy. The purpose of the fort was to hinder movement of Union ships, and to serve as a dropping off point for blockade runners fortunate enough to make it up the mouth of the Cape Fear River. Fort Anderson was built on the ruins of Brunswick Town and was originally named Fort St. Philip, after the ruins of the Revolutionary period church nearby. The name was changed to honor Col. George B. Anderson.
Document 15: Fort Halifax (Maine): Fort Halifax is a former British colonial outpost on the banks of the Sebasticook River, just above its mouth at the Kennebec River, in Winslow, Maine.

A National Historic Landmark, it is the oldest blockhouse in the United States. It is now set in a municipal park, and is open to the public in the warmer months. It was the first of three significant forts which the British built on the major rivers in the Northeast to cut off the native water ways to the ocean (also see Fort Pownall and Fort Frederick (Saint John, New Brunswick)).
