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.

United States Forces Invade Puerto Rico

In the Spanish-American War, U.S. naval victories in the Philippines and Cuba pressured Spain's Caribbean holdings. On July 25, General Nelson A. Miles led approximately 3,300 troops in an amphibious landing at Guánica on Puerto Rico's southern coast, shifting from the original eastern plan. Spanish resistance proved minimal as local forces offered little opposition, allowing rapid advances inland toward Yauco and Ponce. The operation secured key ports and towns within weeks with only a handful of U.S. casualties. Spain signed an armistice in August, transferring control of the island.

Kitchener Defeats Mahdists at Battle of Omdurman

Britain aimed to reconquer Sudan following the 1885 death of General Gordon and years of Mahdist control under the Khalifa. An Anglo-Egyptian army of about 25,000 troops under Major General Horatio Herbert Kitchener advanced along the Nile with gunboats, Maxim machine guns, and modern artillery. On September 2, 1898, near Omdurman outside Khartoum, this force met an estimated 50,000 Mahdist warriors charging in traditional fashion. The battle included a dramatic charge by the 21st Lancers featuring young Winston Churchill. Superior firepower inflicted over 10,000 Mahdist deaths and heavy wounds while limiting Anglo-Egyptian losses to around 500. The victory enabled the swift occupation of Khartoum and the imposition of Anglo-Egyptian rule over Sudan.

Japan Launches Surprise Attack on Port Arthur

At the turn of the 20th century, imperial rivalries intensified over influence in Manchuria and Korea, with Russia seeking Pacific access and Japan aiming to secure its regional dominance after rapid modernization. Diplomatic efforts collapsed when Russia rejected Japanese proposals for spheres of influence. On February 8, 1904, Japanese naval forces under Admiral Togo Heihachiro launched a surprise torpedo attack on the Russian fleet anchored at Port Arthur in Chinese territory, crippling several battleships and initiating open hostilities without a formal declaration of war. The immediate result was the outbreak of the Russo-Japanese War, with Japan gaining naval initiative in the opening phase.

Bulgaria Launches Attacks Triggering Second Balkan War

The First Balkan War of 1912-1913 had seen the Balkan League of Serbia, Greece, Bulgaria, and Montenegro defeat the Ottoman Empire and seize significant territory in Europe. Disputes quickly arose over the division of these gains, particularly in Macedonia, as Bulgaria felt it had received less than its fair share despite major contributions. On the night of June 29, 1913, Bulgarian forces attacked Serbian positions in Macedonia, rapidly expanding the conflict into the Second Balkan War. Greece and later other powers joined against Bulgaria, leading to swift military reversals for the aggressor. The war concluded months later with the Treaty of Bucharest, redrawing borders and weakening Bulgaria.
