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.

Napoleon III Surrenders at Battle of Sedan

The Franco-Prussian War erupted in July 1870 amid disputes over Spanish succession and Prussian influence in Europe. French forces under Emperor Napoleon III and Marshal MacMahon became trapped near the Belgian border after a series of defeats. On September 1, Prussian armies under Helmuth von Moltke completed the encirclement of Sedan, subjecting the French to devastating artillery fire from elevated positions. French cavalry charges proved futile against modern weaponry, and by afternoon Napoleon III ordered the white flag raised. Over 100,000 French troops surrendered the following day, including the emperor himself.

Siege of Paris Ends in Franco-Prussian War

The Franco-Prussian War erupted in 1870 after diplomatic tensions over the Spanish throne candidacy escalated into full conflict between France and the North German Confederation led by Prussia. Following French defeats at Sedan and elsewhere, Prussian forces under Field Marshal Helmuth von Moltke encircled Paris in September 1870, initiating a prolonged blockade that caused severe food shortages and civilian hardship. German artillery bombarded the city in January 1871 to break resistance. On January 28, French leaders signed an armistice with Otto von Bismarck, ending the siege after over four months and leading to the capture of Paris. Regular French troops were disarmed, and the war's outcome paved the way for German unification.

Battle of the Little Bighorn

By the mid-1870s, U.S. government efforts to confine Lakota Sioux, Cheyenne, and Arapaho tribes to reservations clashed with tribal resistance to land loss in the northern Plains. Lieutenant Colonel George Armstrong Custer led the 7th Cavalry Regiment in pursuit of a large Native village along the Little Bighorn River in Montana Territory. On June 25, 1876, Custer divided his forces and attacked the encampment of thousands of warriors led by Sitting Bull and Crazy Horse. The Native coalition overwhelmed Custer's immediate command of over 200 soldiers in fierce fighting that afternoon, resulting in their complete annihilation. The defeat stunned the U.S. public and intensified the Great Sioux War.

War of the Pacific Erupts in South America

Tensions over nitrate-rich territories in the Atacama Desert had simmered between Chile, Bolivia, and Peru since the mid-19th century, fueled by economic stakes in guano and mineral exports. On April 5, 1879, Bolivia declared war on Chile after a dispute over taxes and concessions; Chile responded by declaring war on both Bolivia and Peru. Chilean naval forces quickly moved to blockade Bolivian ports and later targeted Peruvian shipping. The conflict quickly escalated into a regional war involving land and sea campaigns across the Andes and Pacific coast. Initial Chilean successes set the stage for a prolonged struggle that reshaped borders and economies.

USS Maine Explodes in Havana Harbor

Tensions between the United States and Spain over Cuba's independence struggle prompted the U.S. Navy to send the battleship Maine to Havana in January 1898 as a show of force to protect American interests and citizens. On the evening of February 15, a massive explosion tore through the forward section of the ship while it lay anchored in the harbor. The blast killed 266 of the 354 crew members aboard, with the cause initially unclear amid conflicting investigations. American newspapers amplified suspicions of Spanish sabotage through sensational reporting, despite later evidence pointing to an internal accident. The incident rapidly escalated public outrage in the U.S.

Anglo-Egyptian Forces Win Decisive Battle of Atbara

In the late nineteenth century, Britain sought to reassert control over Sudan following the Mahdist uprising that had expelled Egyptian forces in the 1880s. General Herbert Kitchener led an Anglo-Egyptian expeditionary force advancing up the Nile to confront remaining Mahdist armies. On April 8, 1898, approximately 14,000 British, Egyptian, and Sudanese troops under commanders like William Gatacre attacked a fortified Mahdist camp of about 15,000 warriors led by Emir Mahmud near the confluence of the Atbara and Nile rivers. After an artillery bombardment, infantry assaulted the position in fierce hand-to-hand fighting lasting under an hour, resulting in heavy Mahdist losses and the capture of Mahmud. The victory cleared a major obstacle on the path to Khartoum.

U.S. Congress Authorizes Action Against Spain

Tensions between the United States and Spain had escalated over Spain's colonial rule in Cuba, exacerbated by sensationalist reporting on Spanish atrocities and the mysterious explosion of the USS Maine in Havana harbor. On April 20, 1898, Congress passed a joint resolution recognizing Cuban independence, demanding Spanish withdrawal from the island, and authorizing President William McKinley to use military force if needed while disclaiming any U.S. intent to annex Cuba. Spain rejected the ultimatum, severed diplomatic relations, and the United States soon declared war, marking the start of the Spanish-American War.
