Battle of Antietam Fought in Maryland

By mid-1862, Confederate General Robert E. Lee launched his first invasion of the North during the American Civil War, hoping to gain European recognition and supplies. Union forces under George B. McClellan pursued and intercepted Lee's divided army near Sharpsburg. Fighting erupted at dawn on September 17 along Antietam Creek in a series of brutal assaults across cornfields, woods, and a sunken road. Over twelve hours, Union and Confederate troops clashed in the bloodiest single day in American military history, with more than 22,000 casualties. Lee withdrew across the Potomac, ending the immediate threat to Northern soil. President Lincoln used the tactical Union victory to issue the Emancipation Proclamation.

Union Forces Halt Confederate Advance at Perryville

In the fall of 1862, Confederate General Braxton Bragg led an invasion into Kentucky aiming to secure the border state for the South and disrupt Union supply lines during the American Civil War. Union Major General Don Carlos Buell pursued with the Army of the Ohio. On October 8, fighting erupted near the small town of Perryville when Confederate forces under Major General Leonidas Polk launched a surprise attack on Union positions seeking water sources. The battle saw intense fighting across hills and valleys, with Confederate troops gaining local tactical successes but suffering from water shortages and command issues. By evening, Bragg ordered a withdrawal toward Tennessee, leaving Kentucky under firm Union control for the remainder of the war.

Union Army Crosses Rappahannock at Fredericksburg

In the American Civil War, Union General Ambrose Burnside replaced George McClellan and planned a swift advance on Richmond. Logistical delays prevented an early crossing of the Rappahannock River. On December 11, 1862, Union engineers began assembling pontoon bridges under Confederate sniper fire from Fredericksburg. Union artillery bombarded the town to clear the way, allowing troops to cross and occupy Fredericksburg. This positioned the Army of the Potomac for the major battle the following day against Robert E. Lee's forces on Marye's Heights.

Union Army Defeated at Battle of Fredericksburg

During the American Civil War, Union General Ambrose Burnside sought to capture Richmond by crossing the Rappahannock River at Fredericksburg, Virginia. Confederate forces under General Robert E. Lee had fortified the heights west of the town with strong defensive positions. On December 13, 1862, Union troops launched repeated frontal assaults across open ground against entrenched Confederates, suffering devastating casualties from artillery and rifle fire. Despite numerical superiority of nearly 200,000 total combatants, the Union attacks failed spectacularly. Burnside withdrew his army across the river that night, marking one of the war's bloodiest single-day engagements and a major Confederate victory.

Grant Launches Siege of Vicksburg in Civil War

During the American Civil War, control of the Mississippi River was crucial for splitting the Confederacy and securing Union supply lines. After successful campaigns in the Western Theater, Union General Ulysses S. Grant targeted the heavily fortified Confederate stronghold of Vicksburg, Mississippi. On May 18, 1863, Grant's forces surrounded the city, initiating a prolonged siege that combined artillery bombardments, naval support, and infantry assaults. Confederate commander John C. Pemberton defended with limited resources while civilians endured severe hardships. The siege lasted until July 4, when Vicksburg surrendered, marking a turning point in the war.

Battle of Gettysburg Begins in American Civil War

In the summer of 1863, Confederate General Robert E. Lee led his Army of Northern Virginia into Pennsylvania seeking a decisive victory to influence Northern opinion and possibly secure foreign recognition for the Confederacy. Union forces under General George G. Meade positioned themselves to intercept the invasion near the small town of Gettysburg. On July 1, the two armies clashed as Confederate troops advanced from the west and north, encountering Union cavalry and infantry in fierce fighting around the town. The Confederates pushed Union lines back through Gettysburg to Cemetery Hill and Culp's Hill by evening. This opening day set the stage for two more days of intense combat that would become the bloodiest battle of the American Civil War.

Battle of Gettysburg Concludes with Pickett's Charge

During the American Civil War, Confederate General Robert E. Lee's second invasion of the North reached a climax in southern Pennsylvania. Union forces under Major General George G. Meade had taken defensive positions on high ground around Gettysburg after several days of fighting. On the battle's final day, July 3, 1863, Lee ordered a massive infantry assault across open fields against the Union center on Cemetery Ridge, known as Pickett's Charge, following an artillery bombardment. Approximately 12,500 Confederate troops advanced under devastating fire, briefly breaching lines before being repulsed with heavy casualties. Lee then withdrew his army southward, ending the campaign.

Confederate Forces Surrender at Vicksburg

After a 47-day siege, Confederate lieutenant general John C. Pemberton capitulated to Union major general Ulysses S. Grant on July 4, 1863, ending the Battle of Vicksburg. Grant's forces had encircled the Mississippi River stronghold in May, cutting off supplies and bombarding the city relentlessly. Pemberton's 30,000 troops marched out and stacked arms; many were paroled rather than imprisoned. The victory gave the Union complete control of the Mississippi River, splitting the Confederacy in two and fulfilling a key strategic objective outlined by President Lincoln. News of the surrender reached the North on July 4, coinciding with celebrations of Independence Day and boosting morale after earlier setbacks.

54th Massachusetts Leads Assault on Fort Wagner

During the American Civil War, Union forces under Brigadier General Quincy A. Gillmore sought to capture Confederate Battery Wagner on Morris Island, South Carolina, as part of efforts to threaten Charleston. The 54th Massachusetts Volunteer Infantry, one of the first African American regiments raised in the North, was selected to lead the second major assault on July 18, 1863, following an initial failed attempt earlier that month. Colonel Robert Gould Shaw commanded the 54th as roughly 600 of its members advanced across open beach under heavy artillery and musket fire toward the fort's walls. The attack failed to take the position, resulting in over 1,500 Union casualties including the death of Shaw and many from the 54th, though the regiment's...

Union Forces Capture Orchard Knob at Chattanooga

Following defeat at Chickamauga, Union troops under Maj. Gen. William S. Rosecrans were besieged in Chattanooga by Confederate forces led by Gen. Braxton Bragg occupying surrounding heights. Ulysses S. Grant assumed overall command and replaced Rosecrans with George H. Thomas. On November 23, Grant ordered Thomas's Army of the Cumberland to probe Confederate lines and seize the strategic elevation known as Orchard Knob. Approximately 14,000 Union soldiers advanced rapidly, overwhelming a small Confederate rear guard of about 600 men who fired only a single volley before retreating. The capture provided Union artillery positions overlooking Missionary Ridge and served as Grant's headquarters for subsequent operations. This action initiated the decisive Chattanooga campaign.

Battle of Olustee Fought in Florida

During the American Civil War, Union forces sought to disrupt Confederate control in the Deep South and secure Florida's resources. On February 20, 1864, approximately 5,500 Union troops under Brigadier General Truman Seymour advanced toward Lake City and encountered entrenched Confederate forces of similar size led by Brigadier General Joseph Finegan near Olustee Station. The battle unfolded in pine woods over several hours as Union units attacked piecemeal against strong defensive positions. Confederate artillery and infantry fire inflicted heavy casualties, forcing a Union retreat after ammunition shortages threatened their lines. The engagement became the largest battle fought in Florida during the war and helped maintain Confederate dominance in the state's interior.

Union Assault at Cold Harbor Repulsed in Civil War

By spring 1864, Union General Ulysses S. Grant had launched his Overland Campaign to destroy Robert E. Lee's Army of Northern Virginia rather than merely capture Richmond. After inconclusive fighting at the Wilderness and Spotsylvania, Grant maneuvered southeast, seizing the Cold Harbor crossroads in late May. On June 3, Grant ordered a massive frontal assault by three corps against Lee's entrenched lines, which had been reinforced overnight with formidable earthworks and artillery. The attack collapsed within minutes under devastating Confederate fire, resulting in roughly 7,000 Union casualties in under an hour while Lee suffered far fewer. Grant later called the assault his greatest regret, yet the armies remained locked in position until mid-June.

Sherman Begins March to the Sea in Civil War

By late 1864, Union forces under General William Tecumseh Sherman had captured Atlanta after a grueling campaign, dealing a major blow to Confederate morale and logistics. With his supply lines vulnerable and facing orders to continue operations, Sherman decided on a bold strategy of total war against the Southern economy. On November 15, he set out from Atlanta with approximately 60,000 troops, destroying railroads, factories, and crops in a scorched-earth advance toward Savannah. The army moved in multiple columns, foraging off the land and systematically wrecking infrastructure to undermine Confederate support. The March to the Sea lasted about a month and ended with the capture of Savannah just before Christmas. It demonstrated the effectiveness of psychological and economic warfare in...

Confederacy Authorizes Enlistment of Black Soldiers

By early 1865, the American Civil War had turned decisively against the Confederacy, with Union forces outnumbering and outsupplying Southern armies after years of attrition. Confederate President Jefferson Davis and General Robert E. Lee endorsed limited use of enslaved African Americans as soldiers to bolster dwindling ranks, despite long-standing opposition rooted in slavery ideology. On March 13, 1865, the Confederate Congress passed and Davis signed legislation allowing the enlistment of Black men, though the law did not grant freedom to those who served and left implementation to the president. A few companies formed in Richmond in the war's final weeks, but no large units saw combat before the Confederate surrender at Appomattox. The measure represented a desperate last-ditch effort amid...

Battle of Bentonville Begins in American Civil War

In the final months of the American Civil War, Union General William T. Sherman advanced through the Carolinas after his March to the Sea campaign. Confederate General Joseph E. Johnston gathered scattered forces for a last stand to disrupt Sherman's supply lines. On March 19, 1865, Johnston launched a surprise attack near Bentonville, North Carolina, against elements of the Union XIV and XX Corps. Fighting intensified over three days with heavy casualties on both sides. Union reinforcements eventually forced a Confederate withdrawal. The battle represented one of the war's final major engagements in the Eastern Theater.

Appomattox Campaign Opens Final Phase of U.S. Civil War

By early 1865 the American Civil War had dragged on for four years, with Union forces under Ulysses S. Grant pressing Confederate armies in Virginia while William T. Sherman advanced through the South. Confederate General Robert E. Lee commanded the Army of Northern Virginia, which was increasingly short of supplies and manpower after years of attrition. On March 29, Grant launched a major offensive southwest of Petersburg, Virginia, aiming to cut Lee's supply lines and force a decisive engagement. Union troops maneuvered around Confederate positions in a series of movements that became known as the Appomattox Campaign. The offensive quickly gained momentum, leading to the fall of Petersburg and Richmond within days and ultimately Lee's surrender at Appomattox Court House...

Union Forces Occupy Confederate Capital Richmond

By early April 1865, General Robert E. Lee's Army of Northern Virginia faced collapse after defeats at Five Forks and the breaking of Petersburg lines during the American Civil War. Confederate President Jefferson Davis ordered the evacuation of Richmond, Virginia, the Confederate capital, on April 2. On April 3, Union troops under Major General Godfrey Weitzel entered the city without resistance as fires set by retreating Confederates raged. Federal forces quickly restored order, raised the U.S. flag over the Capitol, and began occupation duties. The fall symbolized the imminent end of the Confederacy, occurring just days before Lee's surrender at Appomattox.

Robert E. Lee Surrenders at Appomattox Court House

By early 1865, the American Civil War had dragged on for four years with devastating losses on both sides, as Confederate forces under General Robert E. Lee faced mounting pressure from Union armies led by Ulysses S. Grant. Lee's Army of Northern Virginia, reduced to around 26,000 troops after prolonged campaigns, attempted a final breakout but found itself surrounded near Appomattox, Virginia. On April 9, Lee met Grant in the McLean House to negotiate terms, resulting in the formal surrender of the army. The agreement allowed Confederate soldiers to return home with their horses and sidearms, emphasizing reconciliation over harsh punishment. This event effectively ended major combat operations in Virginia and signaled the collapse of the Confederacy.

Final Battle of American Civil War Fought

More than a month after Robert E. Lee's surrender at Appomattox, Confederate forces in Texas remained active under commanders like Edmund Kirby Smith. Union Colonel Theodore H. Barrett launched an expedition from Brazos Santiago toward Confederate positions near Brownsville. Skirmishing began on May 12 at Palmito Ranch along the Rio Grande, involving cavalry and infantry on both sides with some reports of activity from the Mexican shore. Confederate forces under Colonel John S. Ford counterattacked effectively the next day. The engagement ended with a Confederate victory but no strategic change as the war concluded shortly afterward.

Last Major Confederate Army Surrenders

Following General Robert E. Lee's surrender at Appomattox in April and Joseph E. Johnston's capitulation in North Carolina, scattered Confederate forces remained in the Trans-Mississippi theater. On May 26, 1865, General Edmund Kirby Smith, commanding the Confederate Department of the Trans-Mississippi, formally surrendered his troops at Galveston, Texas. The agreement covered approximately 43,000 soldiers still under arms west of the Mississippi River. This act completed the military collapse of the Confederacy and allowed Union forces to occupy remaining southern territory without further large-scale fighting.

Stand Watie Surrenders Final Significant Confederate Army

By spring 1865, Confederate resistance had largely collapsed following General Robert E. Lee's surrender in Virginia, yet isolated forces continued operations in the western territories. Cherokee leader and Confederate Brigadier General Stand Watie commanded the First Indian Brigade, composed of Cherokee, Seminole, Creek, Choctaw, and Chickasaw soldiers in the Trans-Mississippi Department. On June 23, 1865, at Doaksville in the Choctaw Nation near Fort Towson in Indian Territory, Watie signed a cease-fire agreement with Union Lt. Col. Asa C. Matthews. This action marked him as the last Confederate general in the field to lay down arms. Watie's troops dispersed, ending organized Confederate military presence in the region.

Fetterman Fight Claims 81 U.S. Soldiers

During Red Cloud's War, tensions escalated between U.S. forces building forts along the Bozeman Trail and Lakota, Cheyenne, and Arapaho tribes defending their hunting grounds in Wyoming Territory. On December 21, 1866, a relief party led by Captain William J. Fetterman pursued decoy warriors into an ambush near Fort Phil Kearny. Approximately 2,000 Native warriors overwhelmed the 81 soldiers in a swift and decisive engagement. No U.S. troops survived the battle, marking the worst Army defeat on the Plains until Little Bighorn. The incident prompted reevaluation of military tactics against Native coalitions.

Custer Attacks Cheyenne Village at Washita River

Following the Civil War, U.S. expansion into the Great Plains intensified conflicts with Native American tribes resisting encroachment on traditional lands. In November 1868, Lieutenant Colonel George Armstrong Custer led the 7th Cavalry in a winter campaign against Southern Cheyenne and Arapaho groups. On November 27, without prior reconnaissance to identify the specific village or its peaceful nature, Custer launched a surprise dawn attack on Chief Black Kettle's encampment along the Washita River in present-day Oklahoma. The assault resulted in heavy casualties among the Cheyenne, including the death of Black Kettle, and the destruction of the village and its resources. Custer claimed victory and captured prisoners, though the action drew later criticism for targeting a band under U.S. protection.

France Declares War on Prussia Igniting Franco-Prussian Conflict

Tensions had escalated in Europe following Prussia's victories in prior wars and its leadership in German unification efforts under Otto von Bismarck, challenging French dominance and influence over neighboring states. On July 19, 1870, Emperor Napoleon III of France formally declared war on Prussia after diplomatic provocations, including the manipulated Ems Dispatch, inflamed public opinion in both nations. French forces mobilized expecting a quick victory with superior rifles and mitrailleuse guns, but Prussian organization, railways, and artillery proved decisive from the outset. The declaration drew in other German states allied with Prussia, transforming a bilateral dispute into a broader continental war. Initial French setbacks quickly revealed the mismatch in military preparedness and strategy.
