Context paragraphs:
Fort Sanders (Wyoming): Fort Sanders was a wooden fort constructed in 1866 on the Laramie Plains in southern Wyoming, near the city of Laramie.  Originally named Fort John Buford, it was renamed Fort Sanders after General William P. Sanders who died at the Siege of Knoxville during the American Civil War.  This was the second fort to be named after Sanders, the first being in Knoxville, Tennessee.  The fort was originally intended to protect travelers on the nearby Overland Trail from Indian attacks, but later the garrison was tasked with protecting the workers of the Union Pacific railroad when it arrived in the spring of 1868.  In 1869 the town of Laramie (originally called "Laramie City") was created about 3 mi north of the fort.  Fort Sanders became less important following the construction of Fort D. A. Russell in Cheyenne in 1868, but the War Department maintained it until 1882 when the buildings were sold.

Republican Blues: The Republican Blues were a military company formed in Savannah, Georgia.  The Blues were first organized in 1808 and served at Fort Jackson and in Florida during the War of 1812.  The Blues, typical of Savannah's old military units, were a fraternal social organization and a well-trained military unit.  The Blues defended Georgia's coast from the Union Navy between 1861 and 1864.  Unlike most Confederate units formed during the Civil War, the Republican Blues had been an existing militia organization for over fifty years before the war started.  They recruited from the most prominent families in and around Savannah.  They fought in all the nations wars after The Civil War as part of the Georgia National guard, with the lone exception being The Spanish-American War.  Today they remain in service, as a modular artillery brigade of the Georgia Army National Guard, the 118th Field Artillery.

Fort Stoddert: Fort Stoddert/Stoddard was a stockade fort in the Mississippi Territory, in what is today Alabama.  It was located on a bluff of the Mobile River, near modern Mount Vernon, close to the confluence of the Tombigbee and Alabama Rivers.  It served as the western terminus of the Federal Road which ran through Choctaw lands to Fort Wilkinson in Georgia.  The fort, built in 1799, was named for Benjamin Stoddert also attributed to Amos Stoddard married to Phoebe Reed, contemporaries of Daniel Reed his wife Rose Reed and his brothers Amos Reed and Squire Reed, the secretary to the Continental Board of War during the American Revolution and Secretary of the Navy during the Quasi War.  Fort Stoddert/Stoddard was built by the United States to keep the peace by preventing its own settlers in the Tombigbee District from attacking the Spanish in the Mobile District.

Fort Mifflin: Fort Mifflin, originally called Fort Island Battery and also known as Mud Island Fort, was commissioned in 1771 and sits on Mud Island (or Deep Water Island) on the Delaware River below Philadelphia, Pennsylvania near Philadelphia International Airport.  During the American Revolutionary War, the British Army bombarded and captured the fort as part of their conquest of Philadelphia in autumn 1777.  The United States Army began to rebuild the fort in 1794 and continued to garrison and build on the site through the 19th century.  It housed prisoners during the American Civil War.  The army decommissioned Fort Mifflin for active duty infantry and artillery in 1962 however while the older portion of the fort was returned it to the City of Philadelphia; a portion of the fort's grounds are still actively used by the United States Army Corps of Engineers making it the longest fort in military use in the United States.  Historic preservationists have restored the fort, which is now a National Historic Landmark.

Battle of West Point: The Battle of West Point was fought on April 16, 1865 in West Point, Georgia, during General James H. Wilson's raid in the South during the American Civil War.  This battle was fought at Fort Tyler seven days after Confederate General Robert E. Lee surrendered to Union General Ulysses S. Grant and two days after the assassination of President Abraham Lincoln, making it one of the last battles of the Civil War east of the Mississippi River and making Fort Tyler the last Confederate fort captured by the Union.  The same day, just 30 miles to the south, the Battle of Columbus, Georgia, was fought by another division of Wilson's raiders.  News of the surrender of Robert E. Lee's Army of Northern Virginia reached the opposing forces in Georgia the day after the battle effectively ending the war east of the Mississippi River.

Federal Road (Creek lands): The Federal Road through the territory of the Creek people was a project that started in 1805 when the Creek gave permission for the development of a "horse path" through their nation for more efficient mail delivery between Washington City (modern-day Washington, D.C.) and New Orleans, Louisiana.  This section started at Fort Wilkinson near Milledgeville, Georgia, and ended at Fort Stoddert near Mobile, Alabama.  By the time of the War of 1812, the Federal Road began in Augusta, Georgia, ran through Fort Hawkins (in Macon, Georgia), on to Fort Mitchell, Alabama (near modern Phenix City, Alabama), and finally terminated at Pensacola in Spanish West Florida.

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.

Colerain, Georgia: Colerain was a small trading post located on the St. Marys River in the state of Georgia.  It served as the first location of the United States trading post for trade with the Creek Indians in the mid-1790s, until the factory was relocated to the newly constructed Fort Wilkinson in 1797.  It was also the site of the signing of the Treaty of Colerain between the Creeks and the United States government on June 29, 1796.  The treaty expanded the U.S.-Creek border westward, allowed for Fort Wilkinson's construction, and mandated the removal of the factory there.

Fort Warren (Massachusetts): Fort Warren is a historic fort on the 28 acre Georges Island at the entrance to Boston Harbor.  The fort is pentagonal star fort, made with stone and granite, and was constructed from 1833–1861, completed shortly after the beginning of the American Civil War.  Fort Warren defended the harbor in Boston, Massachusetts, from 1861 through the end of World War II, and during the Civil War served as a prison for Confederate officers and government officials.  The fort remained active through the Spanish–American War and World War I, and was re-activated during World War II.  It was permanently decommissioned in 1947, and is now a tourist site.  It was designated a National Historic Landmark in 1970 as a masterpiece of coastal engineering of the pre-Civil War period, and for its role in the Civil War.  It was named for Revolutionary war hero Dr. Joseph Warren, who sent Paul Revere on his famous ride, and was later killed at the Battle of Bunker Hill.  The name was transferred from the first Fort Warren in 1833, which was renamed Fort Winthrop.

Milledgeville, Georgia: Milledgeville is a city in and the county seat of Baldwin County in the U.S. state of Georgia.  It is northeast of Macon and bordered on the east by the Oconee River.  The rapid current of the river here made this an attractive location to build a city.  It was the capital of Georgia from 1804 to 1868, notably during the American Civil War.  Milledgeville was preceded as the capital city by Louisville and was succeeded by Atlanta, the current capital.  Today U.S. Highway 441 connects Milledgeville to Madison, Athens, and Dublin.
