Context paragraphs:
The Railroad to Freedom: A Story of the Civil War: The Railroad to Freedom: A Story of the Civil War is a children's book by Hildegarde Hoyt Swift.  It is a fictionalized biography of Araminta Ross (later known as Harriet Tubman) telling of her life in slavery and her work on the Underground Railroad.  The book, illustrated by James Daugherty, was first published in 1932 and was a Newbery Honor recipient in 1933.

History of the United States Army: The history of the United States Army began in 1775.  From its formation, the United States Army has been the primary land based part of the United States Armed Forces.  The Army's primary responsibility has been the fighting of land battles and military occupation.  The Corps of Engineers has a major role in controlling rivers inside the United States.  The Continental Army was founded in response to a need for professional soldiery in the American Revolutionary War in order to fight the invading British Army.  Until the 1940s, the Army was relatively small in peacetime.  In 1947, the Air Force became completely independent from the Army Air Forces.  The Army was under the control of the War Department until 1947, and the Defense Department since then.  The U.S. Army fought the War of 1812 (1812–15), American Civil War (1861–65), Spanish–American War (1898), World War I (1917–18), World War II (1941–45), Korean War (1950–53) and Vietnam War (1965–71).  After the Cold War ended in 1991, the U.S. Army has focused on Western Asia, and was involved in the 1991 Gulf War and war in Iraq, and the war in Afghanistan.

Grand Army of the Republic: The "Grand Army of the Republic" (GAR) was a fraternal organization composed of veterans of the Union Army (United States Army), Union Navy (U.S. Navy), Marines and the U.S. Revenue Cutter Service who served in the American Civil War for the Northern/Federal forces.  Founded in 1866 in Decatur, Illinois, and growing to include hundreds of posts (local community units) across the nation (predominately in the North, but also a few in the South and West), it was dissolved in 1956 at the death of its last member, Albert Woolson (1850–1956) of Duluth, Minnesota.  Linking men through their experience of the war, the G.A.R. became among the first organized advocacy groups in American politics, supporting voting rights for black veterans, promoting patriotic education, helping to make Memorial Day a national holiday, lobbying the United States Congress to establish regular veterans' pensions, and supporting Republican political candidates.  Its peak membership, at more than 490,000, was in 1890, a high point of various Civil War commemorative and monument dedication ceremonies.  It was succeeded by the Sons of Union Veterans of the Civil War (SUVCW), composed of male descendants of Union Army and Union Navy veterans.

Washington in the American Civil War: The history of Washington in the American Civil War is atypical, as the territory was the most remote from the battlefields of the American Civil War.  The territory raised a small number of volunteers for the Union Army, who did not fight against the Confederate States Army but instead maintained defensive positions against possible foreign naval or land attacks.  Although the Indian Wars in Washington were recent, there were no Indian hostilities within the area of modern Washington, unlike the rest of the western states and territories, during the Civil War.  At the start of the American Civil War, modern-day Washington was part of the Washington Territory.  On March 3, 1863, the Idaho Territory was formed from that territory, consisting of the entirety of modern-day Idaho, Montana, and all but southwest Wyoming leaving the modern-day Washington as Washington Territory.

William Henry Wallace: William Henry Wallace (March 24, 1827 – March 21, 1901) was a Confederate States Army brigadier general during the American Civil War (Civil War).  Before the Civil War, he was a planter, newspaper publisher, lawyer and South Carolina legislator in 1860 who supported the state calling a secession convention.  He served in the Eastern Theater of the American Civil War, including service as a brigade commander in the Army of Northern Virginia.  After the Civil War, he was a lawyer, planter, South Carolina legislator and circuit judge.

Battle of Fort Sumter: The Battle of Fort Sumter (April 12–13, 1861) was the bombardment of Fort Sumter near Charleston, South Carolina by the Confederate States Army, and the return gunfire and subsequent surrender by the United States Army that started the American Civil War.  Following declarations of secession by seven Southern states, South Carolina demanded that the U.S. Army abandon its facilities in Charleston Harbor.  On December 26, 1860, Major Robert Anderson of the U.S. Army surreptitiously moved his small command from the vulnerable Fort Moultrie on Sullivan's Island to Fort Sumter, a substantial fortress built on an island controlling the entrance of Charleston Harbor.  An attempt by U.S. President James Buchanan to reinforce and resupply Anderson using the unarmed merchant ship "Star of the West" failed when it was fired upon by shore batteries on January 9, 1861.  South Carolina authorities then seized all Federal property in the Charleston area except for Fort Sumter.

Harriet Tubman: Harriet Tubman (born Araminta Ross;  1822 March 10, 1913) was an American abolitionist, humanitarian, and an armed scout and spy for the United States Army during the American Civil War.  Born into slavery, Tubman escaped and subsequently made some thirteen missions to rescue approximately seventy enslaved people, family and friends, using the network of antislavery activists and safe houses known as the Underground Railroad.  She later helped abolitionist John Brown recruit men for his raid on Harpers Ferry, and in the post-war era was an active participant in the struggle for women's suffrage.

Joseph R. Anderson: Joseph Reid Anderson (February 16, 1813 – September 7, 1892) was an American civil engineer, industrialist, and soldier.  During the American Civil War he served as a Confederate general, and his Tredegar Iron Company was a major source of munitions and ordnance for the Confederate States Army.  Starting with a small forge and rolling mill in the mid-1830s, It was a flourishing operation by 1843 when he leased it.  He eventually bought the company outright in 1848 and forcefully and aggressively built Tredegar Iron Works into the South's largest and most significant iron works.  When the Civil War broke out he entered the Army as a Brigadier General in 1861.  Shortly after he was wounded and then resigned from the Army returning to the iron works.  It was the Confederacy's major (and for much of the war only) source of cannons and munitions, employing some 900 workers, most of whom slaves.  His plant was confiscated by the United States In 1865, but returned to him in 1867 and he remained president until his death.  Anderson was very active in local civic and political affairs.

Regular Army (United States): The Regular Army of the United States succeeded the Continental Army as the country's permanent, professional land-based military force.  Even in modern times the professional core of the United States Army continues to be called the Regular Army.  From the time of the American Revolution until after the Spanish–American War, state militias and volunteer regiments organized by the states (but thereafter controlled by federal authorities and federal generals in time of war) supported the smaller Regular Army of the United States.  These volunteer regiments came to be called United States Volunteers (USV) in contrast to the Regular United States Army (USA).  During the American Civil War, about 97 percent of the Union Army was United States Volunteers.
