Notes

Battle of Fort Sumter Apr 12-13, 1861
The battle of Fort Sumter was fought in Fort Sumter near Charleston, and the surrender of the North triggered the civil war.
Afterward, South Carolina seceded, and it demanded the north to abandon everything in Charleston Harbor. On the 26 of December, Major Robert Anderson moved his small army from exposed Fort Moultrie to secure Fort Sumter, a firm fortress built on an island in charge of the entrance of Charleston Harbor. To send support, President James Buchanan of the U.S. army sent the 'Star of the West', sadly it was unsuccessful when it was destroyed by shore batteries. South Carolina authorities then took all Federal property in Charleston area, except for Fort Sumter. Overall, a victory for the confederates.

First Battle of Bull Run/First Battle of Manassa July 21, 1861
The first major battle in the civil war was the First Battle of Bull Run, also known as the First Battle of Manassa, which ended in another confederate victory. The action took place on July 21, 1861, in Prince William County, Virginia, just north of the city of Manassas and approximately 25 miles west-southwest of Washington, D.C., the Union's capital. The Union's troops were slow in positioning themselves, giving Confederate reinforcements time to arrive by railroad. Each side had roughly 18,000 inadequately trained and badly led troops in their first battle. It was a Confederate triumph, with a disorganized retreat of the Union forces.

Siege of Yorktown September 28-October 19, 1781
The siege of Yorktown, ended on October 19, 1781, at Yorktown, Virginia. It was a success for not only the American Continental Army troops managed by General George Washington but also a win for French Army troops directed by the Comte de Rochambeau over a British army commanded by British peer and Lieutenant General Charles Cornwallis. At the culmination of the Yorktown campaign, the siege proved to be the last major land battle of the American Revolutionary War in the North American region. The capture of Cornwallis and his army prompted the British government to negotiate an end to the conflict. The battle boosted faltering American morale and revived French enthusiasm for the war, as well as undermining popular support for the conflict in Great Britain.

Battle of Shiloh April 6-7, 1862
The Battle of Shiloh was a battle in the Western portion of the American Civil War, fought April 6–7, 1862, in southwestern Tennessee. A Union troop called 'the Army of the Tennessee' had moved through the Tennessee River deep into Tennessee and was settled mainly at Pittsburg Landing on the west bank of the river, where the Confederate Army of Mississippi ambushed Grant's army from its base in Corinth, Mississippi. Johnston was fatally injured during the fighting; Beauregard took command of the army and decided against pressing the attack late in the evening. Overnight, Grant was reinforced by one of his divisions stationed farther north and was joined by three divisions from the Army of the Ohio. The Union forces began a surprising counterattack the subsequent morning which reversed the Confederate accumulations of the preceding day.

Capture of New Orleans April 25–May 1, 1862
The capture of New Orleans during the American Civil War was a significant turning point in the war, which exceedingly supported the capture of the Mississippi River, which is where they got their supplies and would split the confederacy in half. Having fought past Forts Jackson and St. Philip, the Union was unopposed in its capture of the city itself, which was spared the destruction suffered by many other Southern cities. However, the argumentative administration of the city by its U.S. Army military governor caused lasting irritation. This capture of the largest Confederate city was a principal turning point and an occurrence of global interest.

Second Battle of Bull Run/Second Battle of Manassas August 29-30, 1862
The Second Battle of Bull Run/Manassas was fought August 28–30, 1862 in Prince William County, Virginia. It was the culmination of the Northern Virginia Campaign waged by Confederate Gen. Robert E. Lee's Army of Northern Virginia, against Union Maj. Gen. John Pope's Army of Virginia. The battle was a much larger scale than the First Battle of Bull Run fought in the same area.

Battle of Antietam September 17, 1862
The Battle of Antietam, also known as the Battle of Sharpsburg, was fought on September 17, 1862, between Confederate General Robert E. Lee's Army of Northern Virginia and Union General George B. McClellan's Army of the Potomac, near Sharpsburg, Maryland and Antietam Creek. Part of the Maryland Campaign, it was the first field army level engagement in the Eastern area of the American Civil War to take place on Union soil. It was the bloodiest day in United States military history, with a combined amount of 22,717 dead, wounded, or missing.

Battle of Fredericksburg December 11-15, 1862

Burnside and the Confederate Army of Northern Virginia under General Robert E. Lee, was part of the Union Army's futile frontal attacks on December 13 against entrenched Confederate defenders on the heights behind the city. It is known as one of the most one-sided battles of the war, with more than twice the union soldiers killed compared to the confederates. A witness of the battlefield described the battle to U.S. President Abraham Lincoln as a "butchery".

Battle of Chancellorsville April 30-May 6, 1863
The Battle of Chancellorsville was an important battle of the American Civil War and the primary battle of the Chancellorsville campaign. It was fought in Spotsylvania County, Virginia, near the settlement of Chancellorsville. The campaign pitted Union Army Maj. Gen. Joseph Hooker's Army facing an army of fewer than half its size, which was General Robert E. Lee's Confederate Army.

Siege of Vicksburg May 18-July 4, 1863

Grant and his 'Army of the Tennessee' crossed the Mississippi River and forced the Confederate Army of Mississippi, led by Lt. Gen. John C. Pemberton, into the defensive lines surrounding the fortress city of Vicksburg, Mississippi. Capturing Vicksburg completed the second part of the Northern strategy, the Anaconda Plan, which was vital to the war.

Battle of Gettysburg July 1-3 1863

Lee's Army, blocking Lee's invasion of the North.

Battle of Chattanooga November 23–25, 1863
The Chattanooga Campaign was a series of maneuvers and battles in October and November 1863, during the American Civil War. Following the defeat of Maj. Gen. William S. Rosecrans's Union Army of the Cumberland at the Battle of Chickamauga in September, the Confederate Army of Tennessee below Gen. Braxton Bragg blockaded Rosecrans and his men by maintaining key high ground around Chattanooga, Tennessee.

The Battle of Atlanta July 21, 1864
The Battle of Atlanta was a battle of the Atlanta Campaign. Continuing their summer campaign to capture the major rail and supply center of Atlanta, Union forces controlled by William Tecumseh Sherman overwhelmed and overpowered Confederate forces protecting the city. Despite the implication of finality in its name, the battle occurred midway through the campaign, and the city did not fall until September 2, 1864, after a Union siege and numerous attempts to capture railroads and supply lines leading to Atlanta.

Sherman's March to the Sea November 15-December 21, 1864
Sherman's March to the Sea was a military campaign led through Georgia from November 15 to December 21, 1864, by Maj. Gen. William Tecumseh Sherman of the Union Army. The campaign started with Sherman's troops departing the captured city of Atlanta and concluded with the capture of the port of Savannah. His forces followed a "scorched earth" strategy, destroying military targets as well as industry, infrastructure, and civilian property, obstructing the Confederacy's economy and transportation systems. The operation lead to the eventual surrender of the confederacy.
