Battle of Yungay Ends Peru-Bolivian Confederation

The Peru-Bolivian Confederation, led by Andrés de Santa Cruz, had united the two nations since 1836, alarming neighboring states over regional power balances. Chile, allied with dissident Peruvian forces, formed the United Restoration Army under General Manuel Bulnes. On January 20, 1839, this combined force of roughly 5,400 men attacked Santa Cruz's Confederate army of about 6,000 near Yungay in northern Peru. After intense fighting lasting several hours, the Restoration Army secured a decisive victory. Santa Cruz fled into exile, and the confederation dissolved immediately afterward.

Sole Survivor of Kabul Retreat Reaches Jalalabad

During the First Anglo-Afghan War, British forces under Major-General William Elphinstone occupied Kabul but faced a popular uprising in late 1841, forcing a negotiated retreat toward the garrison at Jalalabad in early January 1842. The column of roughly 4,500 soldiers and 12,000 camp followers endured brutal winter conditions, ambushes by Afghan tribesmen, and starvation as they marched through mountain passes. By January 13, after days of massacre culminating near Gandamak, Assistant Surgeon William Brydon, severely wounded with part of his skull sheared by a sword (saved by a magazine in his hat), rode alone into Jalalabad on a dying pony. He reportedly answered queries about the army's fate with the words "I am the army," becoming the only European to...

U.S. Naval Academy Established in Annapolis

By the mid-nineteenth century, the United States Navy faced challenges in training officers amid growing maritime responsibilities and incidents like the Somers mutiny that highlighted the need for formal education. Secretary of the Navy George Bancroft advocated for a dedicated shore-based institution to replace inconsistent shipboard apprenticeship. On October 10, 1845, the Naval School opened at Fort Severn in Annapolis, Maryland, with an initial class of fifty midshipmen and seven professors. The curriculum combined academic studies in mathematics, navigation, and languages with practical seamanship. Within five years the school was redesignated the United States Naval Academy, establishing a permanent model for professional naval officer education.

British Forces Win Decisive Battle of Sobraon

The First Anglo-Sikh War erupted in 1845 as tensions rose between the expanding British East India Company and the Sikh Empire in Punjab. British commander Sir Hugh Gough advanced against Sikh positions along the Sutlej River after earlier clashes. On February 10, 1846, British and Indian troops launched a coordinated assault on the Sikh Khalsa Army entrenched at Sobraon, overcoming fog-delayed starts and heavy defenses. Intense artillery and infantry fighting led to the collapse of the Sikh line and a disastrous retreat across a damaged bridge. The victory secured British control and ended the war with the Treaty of Lahore.

U.S. Congress Declares War on Mexico

Tensions over Texas annexation and border disputes escalated after the Republic of Texas joined the United States. President James K. Polk sought congressional approval amid clashes along the Rio Grande. On May 13, 1846, Congress overwhelmingly passed a declaration of war against Mexico following the Thornton Affair. The vote reflected strong Southern support and debates over expansion and slavery. War appropriations and militia organization followed immediately. The conflict lasted until 1848 and redrew North American boundaries.

Battle of Buena Vista Begins in Mexican-American War

During the Mexican-American War, U.S. forces under General Zachary Taylor advanced into northern Mexico while Mexican General Antonio López de Santa Anna marched a larger army northward from central Mexico to counter them. On February 22, 1847, Santa Anna's approximately 15,000 troops positioned themselves around the outnumbered American force of about 5,000 at Angostura Pass near Buena Vista hacienda in Coahuila. Taylor rejected a surrender demand, and fighting erupted that afternoon with artillery exchanges and infantry probes on the rugged terrain. The battle continued into the next day with fierce hand-to-hand combat and cavalry charges. American artillery and defensive stands ultimately forced a Mexican withdrawal despite heavy losses on both sides.

U.S. Forces Capture Chapultepec Castle

As part of the Mexican-American War, U.S. General Winfield Scott advanced on Mexico City after victories at Veracruz and Cerro Gordo. Chapultepec Castle, serving as a military academy and fortress on a hill overlooking key approaches, stood as the final major obstacle. American artillery bombarded the position on September 12 and into the 13th before infantry assaults, including U.S. Marines, stormed the walls. Mexican defenders, including young cadets, fought fiercely but surrendered the castle by mid-morning. The capture opened the gates to Mexico City.

U.S. Forces Capture Mexico City

The Mexican-American War began in 1846 over territorial disputes following U.S. annexation of Texas. In March 1847, General Winfield Scott launched an amphibious landing at Veracruz and advanced inland through a series of victories against Mexican forces. On September 14, 1847, Scott’s army entered Mexico City, raising the American flag over the National Palace in the Hall of Montezuma. The occupation effectively ended major combat operations, though scattered resistance continued. The war concluded with the Treaty of Guadalupe Hidalgo in 1848, which transferred vast territories to the United States.

Britain and France Declare War on Russia

Tensions over influence in the Ottoman Empire and the Eastern Question escalated after Russia's victory at the Battle of Sinop in late 1853. Britain and France, seeking to curb Russian expansion and protect their strategic interests in the Black Sea region, issued an ultimatum that Russia ignored. On March 28, 1854, Britain formally declared war, with France following suit shortly thereafter. This alliance with the Ottoman Empire and later Sardinia transformed a regional conflict into a broader European war. The declarations committed major powers to a prolonged campaign focused on the Crimean Peninsula. Naval and land operations soon followed.

Charge of the Light Brigade at Balaclava

In the Crimean War, British, French, and Ottoman forces besieged the Russian naval base at Sevastopol on the Black Sea. On October 25, Russian forces attacked British positions at Balaclava to disrupt supply lines. A misunderstood order from British commander Lord Raglan directed the Light Brigade cavalry, under Lord Cardigan, to charge Russian artillery in a narrow valley. The brigade suffered heavy casualties from flanking fire but briefly engaged the guns before retreating. The action, though tactically flawed, highlighted issues of command communication in the allied campaign.

Fort Sumter Surrenders to Confederates

As tensions over slavery and states' rights escalated following Abraham Lincoln's election, South Carolina seceded and demanded the evacuation of the federal garrison at Fort Sumter in Charleston Harbor. Major Robert Anderson refused, leading to a 34-hour bombardment by Confederate forces under General P.G.T. Beauregard beginning April 12. On April 13, with supplies exhausted and the fort heavily damaged but no fatalities among defenders, Anderson surrendered the fort. The bloodless victory for the Confederacy was hailed in the South as a major triumph. Lincoln responded by calling for 75,000 volunteers, prompting additional Southern states to secede.

Robert E. Lee Assumes Virginia Confederate Command

As the American Civil War erupted following the secession of Southern states, Virginia's decision to join the Confederacy in April 1861 created an urgent need for experienced military leadership. On April 23, 1861, Robert E. Lee, a respected U.S. Army colonel and veteran of the Mexican-American War, resigned his federal commission and accepted command of Virginia's state forces as a major general. Lee had been offered command of the Union army but chose loyalty to his home state over the Union. His appointment brought immediate organization and strategic expertise to the Confederate effort in the vital eastern theater. Within weeks, he coordinated the defense of Richmond and began building what would become the Army of Northern Virginia.

First Major Battle of American Civil War at Bull Run

In the early months of the American Civil War, both the Union and Confederacy mobilized large volunteer armies with expectations of a quick resolution, as Union forces under Brigadier General Irvin McDowell advanced toward Richmond, Virginia, to end the rebellion swiftly. Confederate troops commanded by Brigadier General P.G.T. Beauregard positioned themselves near Manassas Junction to block the Union advance, with reinforcements from the Shenandoah Valley under Joseph E. Johnston arriving by rail. On July 21, 1861, the opposing armies clashed in the First Battle of Bull Run near Manassas, Virginia, in fighting that involved approximately 35,000 Union and 20,000 Confederate troops across a day of confused engagements around key hills and streams.

Battle of Wilson's Creek Fought in Missouri

Early in the Civil War, Missouri remained in the Union but was bitterly divided, with a pro-Confederate governor and state militia. Union Brig. Gen. Nathaniel Lyon sought to prevent secessionist forces from consolidating. On August 10, 1861, Lyon's outnumbered army of about 5,400 attacked a combined Confederate, Missouri State Guard, and Arkansas force of roughly 12,000 camped near Springfield. Fighting raged on Bloody Hill and surrounding areas; Lyon was killed leading a charge, becoming the first Union general to die in battle. The Confederates held the field, securing southwestern Missouri temporarily and marking the first major Civil War engagement west of the Mississippi.

Union Forces Capture Fort Henry in Civil War

Early in the American Civil War, Union strategists aimed to control the Tennessee and Cumberland Rivers to split the Confederacy and open paths into its heartland. Brigadier General Ulysses S. Grant coordinated with naval forces under Flag Officer Andrew H. Foote to assault the Confederate Fort Henry on the Tennessee River. On February 6, 1862, Foote's gunboat flotilla, including ironclads, bombarded the fort while Grant's infantry approached overland. Confederate commander Brigadier General Lloyd Tilghman surrendered after a brief engagement, with most of the garrison escaping to Fort Donelson. The victory marked the first significant Union success in the Western Theater and demonstrated the effectiveness of combined army-navy operations using ironclad vessels.

Union Captures Fort Donelson in Civil War

In early 1862, as the American Civil War entered its second year, Union forces sought to break Confederate control over key rivers in the Western Theater. Brigadier General Ulysses S. Grant had recently taken Fort Henry on the Tennessee River and turned his attention to Fort Donelson on the Cumberland River. Confederate commanders including John B. Floyd, Gideon Pillow, and Simon Bolivar Buckner defended the fort with around 16,000 troops. After naval bombardment failed on February 14 and a Confederate breakout attempt on February 15 collapsed, Buckner assumed command and requested terms from Grant on February 16. Grant replied with his famous demand for unconditional surrender, resulting in the capture of nearly 13,000 Confederate soldiers. The victory opened the Cumberland...

Monitor and Virginia Clash in First Ironclad Battle

During the American Civil War, the Confederacy converted the scuttled USS Merrimack into the ironclad CSS Virginia to break the Union blockade of Hampton Roads, Virginia. On March 8, Virginia destroyed two wooden Union warships and threatened others. The next morning, March 9, the Union's newly completed ironclad USS Monitor arrived to defend the grounded USS Minnesota. The two armored vessels exchanged fire for several hours in close-range combat, with neither inflicting decisive damage due to their protective plating. The inconclusive duel ended with both ships withdrawing for repairs.

Mexican Forces Defeat French Army at Battle of Puebla

During the Second French Intervention in Mexico, Napoleon III sought to install a European monarchy and collect debts, sending well-equipped troops under General Charles de Lorencez toward Mexico City. General Ignacio Zaragoza commanded a smaller, largely volunteer Mexican force defending the forts of Loreto and Guadalupe overlooking Puebla. On May 5, 1862, the French launched repeated assaults on the fortified positions amid difficult terrain and weather. Mexican defenders repelled the attacks, inflicting heavy casualties and forcing a French retreat to Orizaba. Though the victory delayed rather than halted the invasion, it boosted national morale and resistance against foreign domination.

U.S. Congress Authorizes Army Medal of Honor

During the American Civil War, the Union sought ways to recognize extraordinary valor among its soldiers amid expanding volunteer armies. Earlier legislation had created a Navy version in late 1861. On July 12, 1862, President Abraham Lincoln signed a congressional resolution establishing the Medal of Honor for the Army, to be awarded to enlisted men who distinguished themselves by gallantry in action. The bronze medal featured an eagle clutching arrows and an olive branch above the word "valor," suspended from a ribbon. Initial awards went to soldiers from the Andrews Raid and other engagements, setting the standard for the nation's highest military decoration.

Confederates Win Second Battle of Bull Run

By late August 1862, during the American Civil War, Confederate General Robert E. Lee sought to exploit Union disarray in northern Virginia following the Peninsula Campaign. Lee's Army of Northern Virginia, including corps under Stonewall Jackson and James Longstreet, maneuvered to confront Union forces under General John Pope. The multi-day engagement culminated on August 30 with a massive Confederate counterattack on the Union left flank near Groveton and Henry Hill. Pope's army, surprised by Longstreet's arrival and overwhelmed by coordinated assaults, suffered a decisive defeat and retreated toward Washington, D.C. The victory boosted Southern morale and enabled Lee's first invasion of the North.
