The Civil War Memorial, in the DeKalb County county seat of Sycamore, Illinois, United States, is located in front of the DeKalb County Courthouse on a public square.
 The memorial was erected in 1896 and dedicated in 1897.
 The structure is a memorial to the thousands of DeKalb County residents who served in the American Civil War.
 It incorporates an obelisk which rises to 50 feet (15.2 m) in height.
 The base is adorned with copper sculpture, completed by an unknown sculptor.
 On the east facade of the memorial the word "Antietam", denoting the Battle of Antietam, is misspelled.
 This work of public art underwent its first restoration work in 2005-2006.
The Battle of the Wilderness, fought May 5–7, 1864, was the first battle of Lt. Gen. Ulysses S. Grant's 1864 Virginia Overland Campaign against Gen. Robert E. Lee and the Confederate Army of Northern Virginia in the American Civil War.
 Both armies suffered heavy casualties, a harbinger of a bloody war of attrition by Grant against Lee's army and, eventually, the Confederate capital, Richmond, Virginia.
 The battle was tactically inconclusive, as Grant disengaged and continued his offensive.
Antietam National Battlefield is a National Park Service protected area along Antietam Creek in Sharpsburg, Washington County, northwestern Maryland.
 It commemorates the American Civil War Battle of Antietam that occurred on September 17, 1862.
The Maryland Campaign—or Antietam Campaign—occurred September 4–20, 1862, during the American Civil War.
 Confederate Gen. Robert E. Lee's first invasion of the North was repulsed by the Army of the Potomac under Maj. Gen. George B. McClellan, who moved to intercept Lee and his Army of Northern Virginia and eventually attacked it near Sharpsburg, Maryland.
 The resulting Battle of Antietam was the bloodiest single-day battle in American history and is widely considered one of the major turning points of the war.
The Battle of Antietam , also known as the Battle of Sharpsburg, particularly in the South, was fought on September 17, 1862, near Sharpsburg, Maryland and Antietam Creek as part of the Maryland Campaign.
 It was the first field army–level engagement in the Eastern Theater of the American Civil War to take place on Union soil and is the bloodiest single-day battle in American history, with a combined tally of 22,717 dead, wounded, or missing.
USS "Antietam" (CV/CVA/CVS-36) was one of 24 "Essex"-class aircraft carrier s built during and shortly after World War II for the United States Navy.
 The ship was the second US Navy ship to bear the name, and was named for the American Civil War Battle of Antietam (Maryland).
 "Antietam" was commissioned in January 1945, too late to serve actively in World War II.
 After serving a short time in the Far East, she was decommissioned in 1949.
 She was soon recommissioned for Korean War service, and in that conflict earned two battle stars.
 In the early 1950s, she was redesignated an attack carrier (CVA) and then an antisubmarine warfare carrier (CVS).
 After the Korean War she spent the rest of her career operating in the Atlantic, Caribbean, and Mediterranean.
 From 1957 until her deactivation, she was the Navy's training carrier, operating out of Florida.
The 114th Pennsylvania Volunteer Infantry Regiment was an infantry regiment that served in the Union Army during the American Civil War.
 They were notable for their colorful Americanized version of the Zouave uniform worn in emulation of certain French light-infantry units that became world-famous during France's colonization of North Africa, the Crimean War, and the Second War of Italian Independence fought in the years prior to the American Civil War.
 The regiment was the brain-child of Charles H. T. Collis, an Irish immigrant who settled in Philadelphia becoming a prominent young lawyer.
 Collis initially raised only a small company of men calling them the "Zouaves d'Afrique" which served while attached to other regiments.
 They saw action in the 1862 Shenandoah Valley Campaign, the Battle of Cedar Mountain, and the Battle of Antietam.
 The "Zouaves d'Afrique" were much admired for their military bearing and prowess in battle to the point that it was decided to raise a full-sized regiment which was given the numeric designation of 114th Volunteer Infantry.
Orpheus Saeger Woodward (May 1, 1835–June 26, 1919) was an American Union brevet brigadier general during the period of the American Civil War.
 Before the war, he was a teacher from northwestern Pennsylvania.
 He was part of the 83rd Pennsylvania Infantry.
 Woodward served in the Antietam Campaign and fought at the Battle of Chancellorsville and at Little Round Top in the Battle of Gettysburg after which he was promoted to colonel.
 He was later wounded at Malvern Hill and in the Wilderness which caused him to have his leg amputated.
 He received his appointment as brevet brigadier general dated to March 13, 1865.
USS "Antietam" (CG-54) is a "Ticonderoga"-class guided missile cruiser of the United States Navy.
 "Antietam" was named for the site of the 1862 Battle of Antietam, Maryland, between Confederate forces under General Robert E. Lee and Union forces under Major General George McClellan, during the American Civil War.
 She was built by the Litton-Ingalls Shipbuilding Corporation at Pascagoula, Mississippi and commissioned on 6 June 1987.
 USS "Antietam" earned the 2007 and 2008 Battle Efficiency awards, also known as the Battle E award, for the USS "John C. Stennis" Strike Group.
 "Antietam" was out of operation for a while after running aground while trying to anchor in Tokyo Bay in January 2017.
Jacob C. Higgins (1826–1893) was a native commander of Pennsylvania troops who participated in both major military conflicts of his time, the Mexican-American War and the American Civil War.
 Among his Civil War commands, he guided the 125th Pennsylvania Infantry regiment under heavy fire during the 'Bloodiest Day in American History' at the Battle of Antietam and likewise during the 'Second Bloodiest Day of the Civil War,' May 3, 1863, at the Battle of Chancellorsville.
 Following the muster out and return home of the 125th PA, the Gettysburg Campaign sent cavalry under Confederate General John D. Imboden to threaten vital railroad resources at Altoona and iron production facilities in the Juniata River watershed; in response, Emergency Militia was organized by Colonel Higgins and minimized this northwestern incursion.
