Allied Bombing of Dresden Begins in World War II

As World War II neared its end in Europe, Allied commanders targeted German cities to disrupt transportation, industry, and morale in support of the advancing Soviet forces from the east. Dresden, a major rail hub with cultural significance, had not been heavily bombed earlier in the war. On the night of February 13, 1945, Royal Air Force bombers initiated a massive raid, followed by U.S. Army Air Forces daylight attacks over the next two days. The resulting firestorm destroyed much of the historic city center and killed an estimated 25,000 people.

U.S. Marines Land on Iwo Jima

As the Pacific War entered its final phase in early 1945, U.S. planners targeted Iwo Jima to secure airfields for fighter escorts and emergency landings supporting B-29 raids on Japan. On February 19, approximately 30,000 Marines from the 4th and 5th Divisions stormed the black-sand beaches under heavy naval and air support. Japanese defenders, entrenched in an extensive tunnel network, held fire until the landing forces were ashore before unleashing devastating artillery and mortar fire. The initial assault secured a beachhead but at high cost, with casualties mounting rapidly in the volcanic terrain. The battle would last over a month and become one of the bloodiest in Marine Corps history.

U.S. Marines Raise Flag on Mount Suribachi

In the Pacific Theater of World War II, U.S. Marines landed on Iwo Jima on February 19 to secure airfields for B-29 operations against Japan. After days of intense fighting against entrenched Japanese forces, a platoon reached the summit of Mount Suribachi on February 23. They raised a small U.S. flag around 10:30 a.m., followed later that day by a larger one captured in Joe Rosenthal's iconic photograph. The image of six Marines hoisting the flag symbolized American determination and became one of the war's most enduring symbols.

U.S. Launches Devastating Firebombing of Tokyo

By early 1945, U.S. Army Air Forces shifted to low-altitude incendiary raids against Japanese cities after high-altitude precision bombing proved less effective. On the night of March 9, 334 B-29 Superfortress bombers took off from Pacific bases for Operation Meetinghouse. Pathfinders marked targets in eastern Tokyo with napalm, followed by waves dropping over 1,600 tons of incendiaries. The resulting firestorm consumed densely populated wooden districts, killing an estimated 80,000 to 100,000 people, mostly civilians, and leaving over a million homeless. The raid destroyed 16 square miles of the city.

U.S. Firebombs Tokyo in Deadliest Air Raid

By early 1945, U.S. strategic bombing of Japan had shifted from precision strikes on industry to area incendiary attacks after earlier campaigns proved ineffective due to weather and Japanese dispersal of production. Under General Curtis LeMay, XXI Bomber Command launched Operation Meetinghouse on the night of March 9-10, 1945, sending 279 B-29 Superfortresses loaded with napalm-filled M69 incendiaries over Tokyo at low altitude. The resulting firestorm consumed densely packed wooden neighborhoods, destroying over 267,000 buildings and killing an estimated 90,000 to 100,000 people, mostly civilians. Japanese defenses were overwhelmed, with minimal losses to the attacking force. The raid became the single most destructive conventional bombing attack of the war and influenced subsequent tactics against other Japanese cities.

U.S. Forces Invade Okinawa in WWII

As Allied forces closed in on the Japanese home islands in spring 1945, planners selected Okinawa as a forward base for the anticipated invasion of Japan. The island's airfields and harbors offered critical staging areas within striking distance of the mainland. On April 1, 1945, U.S. Army and Marine units began amphibious landings on the western coast of Okinawa under Tenth Army command. Japanese defenders had prepared extensive fortifications inland rather than contesting the beaches directly. Initial advances met light resistance, allowing rapid seizure of airfields, but the campaign soon turned into a prolonged and costly battle. The operation ultimately secured the island after eighty-two days of fighting.

U.S. Aircraft Sink Japanese Battleship Yamato

In the closing months of World War II in the Pacific, Japan faced mounting losses and prepared desperate measures to defend Okinawa. The massive battleship Yamato, flagship of the Imperial Japanese Navy and one of the largest ever built, was dispatched in Operation Ten-Go on a one-way mission to beach itself and support defenders with its massive guns. Detected by U.S. submarines and reconnaissance, the vessel and its escorts came under sustained attack on April 7, 1945, from hundreds of carrier-based aircraft. Hit by multiple bombs and torpedoes, Yamato capsized and sank after a catastrophic magazine explosion, with the loss of most of her crew.

US Forces Liberate Buchenwald Concentration Camp

As Allied armies advanced deep into Germany in April 1945, Nazi authorities ordered the evacuation of Buchenwald, a major concentration camp near Weimar holding political prisoners, Jews, Roma, and others. Prisoner resistance groups delayed evacuations and, on April 11, seized control of the camp after SS guards fled. Later that afternoon, elements of the U.S. Sixth Armored Division, part of the Third Army, entered the camp and found more than 21,000 survivors. The liberators encountered horrific conditions, including emaciated prisoners and evidence of mass deaths. The event became one of the first major revelations of Nazi camp atrocities to Western forces.

British Forces Liberate Bergen-Belsen Concentration Camp

In the closing weeks of World War II in Europe, as Allied armies advanced deep into Germany, British troops of the 11th Armoured Division reached the Bergen-Belsen camp near Celle on April 15. They found roughly 60,000 emaciated prisoners, many suffering from typhus and other diseases, along with thousands of unburied corpses scattered throughout the site. The camp, originally a prisoner-of-war facility, had become overcrowded with Jewish prisoners and others transferred from eastern camps ahead of the Soviet advance. Commandant Josef Kramer and remaining SS personnel were detained, and British medical teams began immediate efforts to treat survivors and contain the epidemic. The liberation revealed the full scale of Nazi atrocities to Western audiences through photographs and newsreels.

U.S. and Soviet Troops Meet on Elbe River

As World War II in Europe neared its end, advancing Allied and Soviet armies converged on Nazi-held territory from west and east. On April 25, 1945, U.S. reconnaissance units from the First Army encountered Soviet forces near Torgau and Strehla along the Elbe River in Germany. The meeting cut German forces in two, preventing organized retreat or reinforcement between fronts. Soldiers from both sides celebrated the linkup with handshakes and shared rations amid the ruins of war. This event became known as Elbe Day, symbolizing the impending defeat of Nazi Germany.

Italian Partisans Capture Benito Mussolini

By April 1945, Benito Mussolini's Italian Social Republic, a German puppet state in northern Italy, was collapsing under Allied advances and partisan uprisings. On April 25, Mussolini fled Milan disguised in a German uniform, traveling in a convoy toward the Swiss border with his mistress Clara Petacci and other Fascist officials. Early on April 27, the column was stopped at a partisan roadblock near Dongo on Lake Como by members of the 52nd Garibaldi Brigade. After negotiations allowing German troops to proceed, partisans searched the vehicles and discovered Mussolini hiding under a blanket in a truck. He was arrested, disarmed, and taken into custody; Petacci chose to remain with him. The capture ended Mussolini's flight and paved the way for...

Benito Mussolini Executed by Italian Partisans

As Allied forces advanced through northern Italy in the final weeks of World War II in Europe, Benito Mussolini attempted to flee toward Switzerland disguised as a German soldier. Captured by local partisans near Lake Como on April 27, he and his mistress Clara Petacci were held overnight. On April 28, 1945, partisans executed Mussolini and Petacci by firing squad in the village of Giulino di Mezzegra. Their bodies were later transported to Milan and publicly displayed. The execution ended over two decades of Fascist rule in Italy.

U.S. Army Liberates Dachau Concentration Camp

As Allied armies advanced deep into Germany in the final weeks of World War II in Europe, units of the U.S. Seventh Army approached the Dachau complex, the first Nazi concentration camp opened in 1933. On April 29, soldiers from the 42nd and 45th Infantry Divisions encountered railroad cars filled with corpses and emaciated survivors, then accepted the surrender of remaining SS guards after brief resistance. Approximately 32,000 prisoners were freed that day, many of them political detainees, Jews, and others held since the camp’s early years. Troops documented the horrific conditions for later war-crimes proceedings.

Adolf Hitler Commits Suicide in Berlin Bunker

By late April 1945, Soviet forces had encircled Berlin in the final Battle of Berlin, and Nazi Germany's collapse was imminent. Adolf Hitler had retreated to the Führerbunker beneath the Reich Chancellery with close associates. On April 30, 1945, he married Eva Braun the previous day and then committed suicide by gunshot while she took cyanide. Their bodies were burned in the Chancellery garden per his instructions. The event was announced the next day on German radio, accelerating the unconditional surrender of German forces weeks later.

Soviet Forces Announce Capture of Berlin

After weeks of intense house-to-house fighting in the final days of World War II in Europe, Soviet troops under Marshal Georgy Zhukov and others encircled and assaulted the German capital. On May 2, 1945, the Soviet Union announced the fall of Berlin following the suicide of Adolf Hitler days earlier and the collapse of organized German resistance in the city. Simultaneously, the German surrender at Caserta took effect, ending hostilities in Italy. The announcement came after Soviet forces raised their flag over the Reichstag and secured key government districts. The battle had cost tens of thousands of lives on both sides and left the city in ruins. This event effectively marked the end of Nazi Germany in Europe.

Nazi Germany Signs Unconditional Surrender at Reims

By early May 1945, Allied forces had overrun much of Germany and Adolf Hitler had committed suicide, leaving Admiral Karl Dönitz as head of state. German General Alfred Jodl arrived at Supreme Headquarters Allied Expeditionary Force in Reims, France, to negotiate an end to hostilities. On May 7, 1945, shortly after 2 a.m., Jodl signed the unconditional surrender of all German forces on behalf of the German High Command. The document stipulated that fighting would cease at 11:01 p.m. on May 8. A separate ratification ceremony occurred in Berlin the following day to satisfy Soviet demands.

United Nations Charter Signed by 50 Nations

World War II was nearing its end in Europe when delegates from 50 countries gathered in San Francisco for the United Nations Conference on International Organization. The conference aimed to create a new global body to prevent future conflicts after the failures of the League of Nations. On June 26, 1945, representatives signed the United Nations Charter in the Herbst Theatre, establishing the framework for the UN with its principal organs including the Security Council, General Assembly, and International Court of Justice. The document outlined commitments to maintain peace, promote human rights, and foster international cooperation. It required ratification by the five permanent Security Council members and a majority of signatories before taking effect later that year.

Potsdam Conference Opens Among Allied Leaders

With Germany surrendered in May 1945, the final wartime meeting of the Big Three—U.S. President Harry Truman, British Prime Minister Winston Churchill (later replaced by Clement Attlee), and Soviet leader Joseph Stalin—convened to shape postwar Europe and address Japan. Held at Cecilienhof Palace in Potsdam near Berlin from July 17 to August 2, the conference addressed occupation zones, reparations, German demilitarization, and the Potsdam Declaration demanding Japan's unconditional surrender. Truman, newly informed of the successful atomic bomb test, adopted a firmer stance toward Stalin amid growing suspicions over Soviet intentions in Eastern Europe. Discussions revealed emerging fractures in the wartime alliance.

Japanese Submarine Sinks USS Indianapolis

In the final weeks of World War II in the Pacific, the heavy cruiser USS Indianapolis had completed a secret mission delivering atomic bomb components to Tinian. Departing Guam for Leyte, the ship sailed unescorted through waters where Japanese submarines remained active. Just after midnight on July 30, 1945, the submarine I-58 fired two torpedoes that struck the vessel, causing rapid flooding and structural failure. The Indianapolis sank in approximately twelve minutes, taking nearly 300 crew members down with her. Roughly 900 survivors entered the water with limited lifeboats, facing days of exposure, dehydration, and shark attacks before rescue began on August 2.

United States Drops Atomic Bomb on Hiroshima

In the final months of World War II in the Pacific, the United States had developed atomic weapons through the Manhattan Project and sought a rapid end to the conflict with Japan. After Japan's refusal to accept unconditional surrender terms outlined at Potsdam, the B-29 Superfortress Enola Gay, piloted by Colonel Paul Tibbets, took off from Tinian Island carrying the uranium-based bomb nicknamed Little Boy. At approximately 8:15 a.m. local time on August 6, 1945, the bomb detonated over the industrial city of Hiroshima, destroying much of the urban area and killing an estimated 70,000 people instantly. Tens of thousands more died later from injuries and radiation effects. The attack represented the first combat use of a nuclear weapon.

Soviet Union Declares War on Japan in WWII

As World War II neared its conclusion in Europe, the Soviet Union had agreed at the Yalta Conference to enter the Pacific theater against Japan three months after Germany's defeat. On August 8, 1945, Soviet Foreign Minister Vyacheslav Molotov informed the Japanese ambassador in Moscow that the USSR was declaring war, effective the next day. This announcement came two days after the atomic bombing of Hiroshima and shattered Japanese hopes that the Soviets might mediate a negotiated peace. Over one million Soviet troops then invaded Japanese-held Manchuria on August 9, overwhelming the Kwantung Army. The rapid Soviet advances across multiple fronts further isolated Japan diplomatically and militarily.

Atomic Bomb Dropped on Nagasaki

As World War II neared its end in the Pacific, the United States sought to compel Japan's surrender without a costly invasion of the home islands. Following the Potsdam Declaration's demand for unconditional surrender, which Japan rejected, the B-29 bomber Bockscar carried the plutonium implosion device Fat Man toward the primary target of Kokura. Poor visibility forced a switch to the secondary target of Nagasaki on August 9, 1945. The bomb detonated at approximately 11:02 a.m. local time over the Urakami Valley, destroying much of the city and killing an estimated 35,000 to 40,000 people immediately. The blast and subsequent fires devastated industrial and residential areas alike. This marked the second and final use of a nuclear weapon in combat.

Japan's Surrender Announced, Ending World War II

After atomic bombings of Hiroshima and Nagasaki and the Soviet invasion of Manchuria, the Japanese government debated acceptance of Allied surrender terms. Emperor Hirohito intervened to break the deadlock in favor of capitulation. On August 14, 1945, President Harry S. Truman publicly announced Japan's unconditional surrender to the Allies in a radio address that sparked celebrations across the United States and Allied nations. The announcement, later commemorated as Victory over Japan Day in many countries, effectively concluded the most destructive conflict in human history. Formal surrender documents were signed on September 2 aboard the USS Missouri.
