full_context: Document 1: Cedar Grove Plantation: Cedar Grove Plantation, also known as the Charles Walker House, is a Greek Revival plantation house located near Faunsdale, Marengo County, Alabama. It is notable in having been the residence of Nicola Marschall for a brief period while the Walker family owned the property. The house was added to the National Register of Historic Places on 13 July 1993 as a part of the Plantation Houses of the Alabama Canebrake and Their Associated Outbuildings Multiple Property Submission.
Document 2: William Porcher Miles: William Porcher Miles (July 4, 1822 – May 11, 1899) was among the ardent States' Rights advocates, supporters of slavery, and Southern secessionists who came to be known as the "Fire-Eaters." He is notable for having designed the most popular variant of the Confederate flag, originally rejected as the national flag in 1861, but adopted as a battle flag by the Army of Northern Virginia under General Robert E. Lee before being reincorporated by William Tappan Thompson into the second design of the national flag in 1862.
Document 3: Flag of Georgia (U.S. state): The current flag of the state of Georgia was adopted on May 8, 2003. The flag bears three stripes consisting of red-white-red, and a blue canton containing a ring of 13 white stars encompassing the state's coat of arms in gold. In the coat of arms, the arch symbolizes the state's constitution and the pillars represent the three branches of government: legislative, executive, and judicial. The words of the state motto, "Wisdom, Justice, and Moderation", are wrapped around the pillars, guarded by a male figure dressed in colonial attire dating back to the time of the American Revolutionary War. Within the arms, a sword is drawn to represent the defense of the state's constitution. An additional motto, In God We Trust, is positioned underneath these elements acting as the state's "foundation". The ring of stars that encompass the state's coat of arms symbolize Georgia's status as one of the original Thirteen Colonies. The design principle is based on the first national flag of the Confederacy, which was nicknamed the "Stars and Bars".
Document 4: Van Dorn battle flag: The Van Dorn battle flag is a historical Confederate flag with a red field depicting a white crescent moon in the canton and thirteen white stars; and trimmed with gold cord. In February, 1862, Confederate general Earl Van Dorn ordered that all units under his command use this flag as their regimental colors. The 4th Missouri and 15th Arkansas Infantry Regiments carried this flag into battle, as well as some of Van Dorn's old units in the Army of Mississippi and East Louisiana.
Document 5: Rowan Oak: Rowan Oak, also known as William Faulkner House, is William Faulkner's former home in Oxford, Mississippi. It is a primitive Greek Revival house built in the 1840s by Robert Sheegog. Faulkner purchased the house when it was in disrepair in the 1930s and did many of the renovations himself. Other renovations were done in the 1950s. The house sits on 4 landscaped and twenty nine acres of largely wooded property known as Bailey's Woods. One of its more famous features is the outline of Faulkner's Pulitzer Prize–winning novel "A Fable", penciled in graphite and red on the plaster wall of his study. Though the "rowan oak" is a mythical tree, the grounds and surrounding woods of Rowan Oak contain hundreds of species of native Mississippi plants, most of which date back to antebellum times. The alley of cedars that lines the driveway was common in the 19th century. The studs of the house are 4"x4" square cypress, which were hand-hewn. Faulkner drew much inspiration for his treatment of multi-layered Time from Rowan Oak, where past and future seemed to inhabit the present.
Document 6: Twelve Oaks: In Margaret Mitchell's novel "Gone with the Wind", Twelve Oaks is the plantation home of the Wilkes family in Clayton County, Georgia named for the twelve great oak trees that surround the family mansion in an almost perfect circle. Twelve Oaks was described as a "beautiful white-columned house that crowned the hill like a Greek Temple," having true southern charm and whimsy. Margaret Mitchell came up with the idea for The Twelve Oaks, and modeled the home after an actual antebellum mansion located in the historic area of Covington, Georgia. The home that was portrayed as Margaret Mitchell's Twelve Oaks in the film "Gone with the Wind" has been renovated and is now open as a bed and breakfast and event facility in Covington, Georgia, thirty minutes east of Atlanta.
Document 7: Walker Home for Missionary Children: Walker Home for Missionary Children is a historic boarding house complex for the care of the children of religious missionaries while they were away from home. It is composed of eight buildings, located at 161-63, 165, 167 Grove Street, 136, 138, 144 Hancock Street in the Auburndale village of Newton, Massachusetts. The oldest building, the Harding House, was built c. 1850 by the father of Eliza Walker, founder of the Walker Home. The main building in the complex, Walker House, is a large institutional Colonial Revival structure designed by Coolidge & Carlson, architects known for their academic structures, and built after Eliza Walker's original house burned down in 1911.
Document 8: The Marshall House: George Catlett Marshall, who was Army Chief of Staff, special envoy to China, Secretary of State, President of the Red Cross, Secretary of Defense, and namesake of the Marshall Plan, and his wife Katherine Marshall purchased the property for $16,000 in 1941 and lived there until his death on October 16, 1959. Legend has it that Katherine paid the owners $10 earnest money and threw the "for sale" sign into the bushes as she left to discourage the competition. Except for a winter home in Pinehurst, N.C., this house was the only home Marshall ever owned, and was the backdrop to quiet conversations and contemplations of international importance. Katherine gave the house and 3.88 acres to her daughter, Molly Winn, in 1960 while she moved to Pinehurst for permanent residence. When Mrs. Winn expressed her desire to sell the property in the early 1990s, several prominent Leesburg citizens under the leadership of B. Powell Harrison were concerned that the property might fall into commercial hands and be demolished and urged the Town of Leesburg to purchase it. That proved to be impossible, so the citizens formed the George C. Marshall Home Preservation Fund, later the George C. Marshall International Center, and purchased the Marshall House for $2.3 million. After renovations costing more than $4.5 million, the house opened as a museum on Veterans Day in 2005. Much of the money for the purchase and renovation was donated by European nations that had benefited from the Marshall Plan. Further funding was provided by grants from the Commonwealth of Virginia, National Park Service (Save America’s Treasures program), U.S. Department of Housing and Urban Development, Garden Club of Virginia, and generous private donations.
Document 9: Flag of Mississippi: The flag of the state of Mississippi was first adopted by the U.S. state of Mississippi in April 1894, replacing the unofficial flag that had been adopted in 1861 when Mississippi was a Confederate state. The flag was subsequently repealed in 1906 but remained in "de facto" use. When a referendum failed for a new design in April 2001, the state legislature voted to readopt the historic design that same month. Since Georgia adopted a new state flag in 2003, the Mississippi flag is the only U.S. state flag to include the Confederate battle flag's saltire.
Document 10: Cuba Plantation: Cuba Plantation is a historic plantation house located in Faunsdale, Alabama.

Andrew Calhoun was the son of John C. Calhoun, seventh Vice President of the United States, who frequented the Octagon House while in Washington, D.C. as Secretary of War and later an independent outlier of the anti-Jacksonian Whig Party, later realigning himself with the Democrats' policies. It was sold in 1863 to Tristram Benjamin Bethea, who resided in Montgomery County, Alabama. Originally a one-story structure, the house was later enlarged on the ground floor and a second story added by the Bethea family. The house was added to the National Register of Historic Places on July 13, 1993, as a part of the Plantation Houses of the Alabama Canebrake and Their Associated Outbuildings Multiple Property Submission.

Document 13: Hawthorne House (Pine Apple, Alabama): The Hawthorne House, also known as the Col. J. R. Hawthorne House, is a historic plantation house in Pine Apple, Alabama, USA. The two-story wood-frame house was built in 1854 for Joseph Richard Hawthorne by Ezra Plumb. Joseph Hawthorne was born in 1805 in North Carolina, but the family had relocated to Wilkinson County, Georgia by 1810. Hawthorne moved to Conecuh County, Alabama in the 1830s and finally settled in Pine Apple in the 1850s. He owned several large plantations in Conecuh and Wilcox counties. He died in Pine Apple in 1889. The house was sold out of the family after his death, but was brought back into the family when acquired in 1935 by Gladys Hawthorne Whitaker and her brother, Dr. Julian Hawthorne, a New York physician. They restored the house and it remained in the family until Mrs. Whitaker's death in 1980. The house was recorded by the Historic American Buildings Survey in 1937.

Twenty-nine five-pointed stars appear on the flag: twenty-five small white stars within the blue border, and four larger blue stars in the white diamond. The inscription "ARKANSAS" appears in blue within the white lozenge, with one star above and three stars below. The star above and the two outer stars below point upwards; the inner star below points downwards. The flag was designed by Willie Hocker of Jefferson County, a member of the Pine Bluff Chapter, Daughters of the American Revolution.
Document 15: American Civil War Corps Badges: Corps badges in the American Civil War were originally worn by soldiers of the Union Army on the top of their army forage cap (kepi), left side of the hat, or over their left breast. The idea is attributed to Maj. Gen. Philip Kearny, who ordered the men in his division to sew a two-inch square of red cloth on their hats to avoid confusion on the battlefield. This idea was adopted by Maj. Gen. Joseph Hooker after he assumed command of the Army of the Potomac, so any soldier could be identified at a distance.
