History of the Marine Corps

From the ridges of Blanc Mont to the jungles of China, this chapter follows the Marines as they emerge from the Great War hardened and transformed. It opens on the blood-soaked hills of France, where the Corps shattered German lines at Blanc Mont and the Meuse, then traces their return to a nation eager for peace but uncertain of their purpose.  In the decades between wars, the Marines rebuilt themselves on football fields, in classrooms, and on ponies at Peking. They forged doctrine, studied war, and turned lessons from Haiti and France into the blueprint for amphibious victory. By the eve of World War II, they had become a force unlike any in history and ready for the storm to come.

From the jungles of the Caribbean to the wheatfields of France, this chapter traces the Marines' transformation from a small expeditionary force into a modern fighting corps. In the Dominican Republic and Haiti, they battled rebellion and unrest, forging legends in men like Smedley Butler, Dan Daly, and Herman Hanneken. Their story carries on through the siege and smoke of the Boxer Rebellion and into the trenches of the Great War, where the Marines proved their worth and defined what it means to wear the eagle, globe, and anchor.  Support the Series Listen ad-free and a week early on historyofthemarinecorps.supercast.com Donate directly at historyofthemarinecorps.com Try a free 30-day Audible trial at audible.com/marinehistory Social Media Instagram - @historyofthemarines Facebook - @marinehistory Twitter - @marinehistory

This episode traces the Marine Corps' transformation from the late 1800s into the modern force recognized today. It begins with the creation of Parris Island and the evolution of Marine training, from tents and marshland to a world-class recruit depot tested by war, tragedy, and reform. The story moves through Panama, where Marines became America's instrument of order, and into the age of steel ships and global ambition. It follows their battles in Cuba, the Philippines, and across Central America during the Banana Wars, where the Corps learned the lessons of small wars, air-ground coordination, and constabulary duty. Figures like Charles Heywood, John A. Lejeune, and Smedley Butler emerge as the architects of a professional, expeditionary force. By the time the last Marines left Nicaragua in 1933, the Corps had been reshaped, no longer a naval guard but a global instrument of American power, forged in hardship and defined by purpose.

After the Revolution left America without a Navy or Marine Corps, global tensions forced the young republic to rebuild its strength at sea. This episode follows the Corps' revival in 1798 and its first tests in battle, from the Quasi-War with France to the campaign against the Barbary pirates and the daring raid to burn the captured frigate Philadelphia. It explores how Commandant William Ward Burrows shaped the Corps' discipline and structure, how the Marine Band became "The President's Own," and how Lieutenant Presley O'Bannon led the first Marines across the desert to Derne. We end with the start of the War of 1812, when Marines proved their courage from the decks of Old Ironsides to the shores of Canada, securing their place as a permanent part of the nation's defense.   Support the Series Listen ad-free and a week early on historyofthemarinecorps.supercast.com Donate directly at historyofthemarinecorps.com Try a free 30-day Audible trial at audible.com/marinehistory Social Media Instagram - @historyofthemarines Facebook - @marinehistory Twitter - @marinehistory

Born in a Philadelphia tavern at the height of the Revolution, the Marine Corps began as America's first seaborne fighting force. This episode traces that origin. Out of the smoke and uncertainty of rebellion, Samuel Nicholas gathered the first Marines from the city's streets. They were craftsmen, sailors, and laborers who became the sharp edge of a new nation. They launched their first assault in the Bahamas, fought beside Washington on the Delaware, and held fast through both triumph and disaster. From frozen rivers at Trenton to burning ships at Penobscot, Chapter 1 follows the Continental Marines. They were poorly equipped and often outnumbered, but they fought across every front of the Revolution and forged the traits that would define the Corps.   Support the Series Listen ad-free and a week early on historyofthemarinecorps.supercast.com Donate directly at historyofthemarinecorps.com Try a free 30-day Audible trial at audible.com/marinehistory Social Media Instagram - @historyofthemarines Facebook - @marinehistory Twitter - @marinehistory

In 1941, as the world plunged deeper into war, a small contingent of U.S. Marines found themselves far from the Pacific jungles, engaging in missions that would not capture headlines but were no less critical. Deployed far from the Pacific, they prepared the groundwork for larger Allied operations. In London, amidst the Blitz, they protected the American Embassy and took on tasks that extended far beyond their original mission. Across the Atlantic, in the rugged terrain of Scotland, Marines were pushed to their physical limits, learning unconventional warfare tactics from British Royal Marines, skills that would later define the elite Marine Raiders. Though often unsung, these Marines quietly helped lay the foundation for major victories to come. Their early, discreet efforts were crucial in shaping the success of later, larger campaigns and establishing the Marine Corps as a force capable of adapting to the ever-changing demands of global conflict. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

In the spring of 1945, the Battle of Okinawa became the bloodiest fight of the Pacific War. What was meant to be the final step toward Japan turned into a storm of mud, coral, and fire that tested every limit of courage and endurance. This episode follows the Marines through the final weeks of the campaign. It is a story of bravery and exhaustion, of shattered armies and civilians trapped between them, of generals who chose death over surrender, and of the staggering cost of victory. When the guns finally fell silent, more than two hundred thousand people were dead. The island lay in ruins, but amid that devastation came moments of humanity. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

By May 1945, Okinawa had become a war of exhaustion. The island's southern ridges, scarred by months of bombardment, hid Japan's last and strongest defensive line. When the Tenth Army resumed its drive on 11 May, the Marines faced terrain as deadly as any in the Pacific. To the east, the 1st Marine Division attacked into Wana Draw, a maze of ravines and caves leading toward Shuri Castle. A few miles west, the 6th Marine Division struck at Sugar Loaf Hill, a small rise commanding the road to Naha. For seven days, the two divisions clawed forward through mud, rain, and fire. By 18 May, both Wana and Sugar Loaf lay in Marine hands. The victory cracked the Shuri Line and forced the enemy's retreat. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

This episode begins with the thunder of Easter Sunday, 1945, when Marines and soldiers of the U.S. Tenth Army hit the beaches of Okinawa. After weeks of naval bombardment, they expected hell on the sand. Instead, they found silence. The Japanese had pulled back, choosing to fight from caves and ridges deep inland. That calm didn't last. Within days, night counterattacks and ambushes tested the Marines' resolve. The 6th Division clawed through the Motobu Peninsula's jagged hills while the 1st secured the plains below. Offshore, the fleet endured waves of kamikaze strikes, and the battleship Yamato made its final, suicidal run. By late April, northern Okinawa was in American hands. The Marines had earned their victory ridge by ridge, cave by cave. But as they looked south toward Shuri's fortified lines, they knew this was only the beginning. The battle for Okinawa, the last and bloodiest campaign of the Pacific, was still waiting. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

By 1945, Okinawa stood as the last barrier before the homeland, vital to both Japanese defense and American invasion plans. The Japanese abandoned beach defenses and instead transformed ridges, caves, and limestone plateaus into layered strongholds, preparing to bleed the invaders inland. The United States assembled the Tenth Army to launch the largest amphibious assault of the Pacific. The episode closes on L-Day, April 1, 1945, as four divisions landed across Hagushi beaches, beginning the climactic battle that would test Okinawa's terrain, its people, and both armies to the limit. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

The battle's later weeks were a relentless grind through Iwo Jima's strongest defenses. Marines battered the “Meat Grinder” of Hill 382, Turkey Knob, and the Amphitheater, where progress was measured in yards and companies were reduced to fragments. Caves, reverse-slope positions, and night counterattacks forced constant, costly use of tank–infantry teams, flamethrowers, and demolitions. This episode will finish up our Iwo Jima series. We'll close with the sobering numbers, highlight the overlooked contributions of Montford Point Marines, and also examine the extraordinary sacrifice of Navy corpsmen. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

While the photographs from Suribachi raced around the world, the Marines prepared for a new and even more punishing fight. Their next objective was the Motoyama Plateau. Three airfields surrounded by a citadel of pillboxes, bunkers, and caves woven together to bleed the invasion dry. At the heart of this defensive belt lay three features: the heights of Hill 382, the blockhouse of Turkey Knob, and the bowl of the Amphitheater. Together, they formed the Meat Grinder. Entire companies were cut down to platoon strength. Riflemen crawled through volcanic ash under fire from every angle, engineers dragged flamethrowers and satchel charges against concrete walls that refused to break, and corpsmen pulled the wounded out of craters while shells burst overhead. The Meat Grinder epitomized Iwo Jima: a place won not by a single breakthrough, but by relentless endurance, teamwork, and sacrifice. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

No picture is more tied to Iwo Jima than the flag raising on Mount Suribachi. On February 23, 1945, Associated Press photographer Joe Rosenthal captured the moment when six Marines raised the Stars and Stripes over the rocky summit. It has been sculpted in bronze, carved into memory, and etched into the collective image of the Marine Corps. For many, Suribachi is Iwo Jima. The photo was only one moment. The 550-foot volcanic cone at the island's south tip, towered over the beaches. Japanese mortars, artillery, and machine guns fired from its slopes onto the landing zones of the 5th Marine Division.  Mount Suribachi was the job of the 28th Marines. They fought from the opening landings, driving around its base until the volcano was cut off. For four days, they clawed through dug-in defenses. On February 23, they climbed to the summit. In this episode, we tell Suribachi's full story: its importance, the defenses hidden inside it, the assault that sealed it off, the climb to the top, and what the flag raising meant then and now. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

On the morning of February 19th, 1945, the invasion of Iwo Jima began. The Marines were coming in force. The 4th and 5th Marine Divisions led the assault, backed by the 3rd in reserve. Offshore, hundreds of ships filled the sea, their decks crowded with men climbing down cargo nets into landing craft and amphibious tractors. This episode takes us into the brutal opening six days of fighting that marked the start of the thirty-six-day campaign. We'll set aside Mount Suribachi for now and turn instead to the central and northern fronts, where the hardest battle to secure ground was fought. This is the story of those opening days. The confusion on the beaches, the struggle across the airfields, and the steep price paid for every yard. Iwo Jima had become a trial of endurance, and the battle was only starting. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

By early 1945, the Pacific war had reached a turning point. The United States held the Marianas. From there, B-29 bombers struck directly at Japan, but the road to Tokyo was still dangerous.  Halfway along that road lay Iwo Jima, a tiny volcanic island of black sand, jagged rock, and sulfur fumes. On the map it looked insignificant, but its location gave it enormous weight. For Japan, it was part of Tokyo Prefecture itself, “the doorkeeper to the capital.” For America, it was both a threat and an opportunity: a fighter base that could harass bombers, or an emergency airfield that could save them. General Kuribayashi was ordered to turn Iwo Jima into a fortress. Beneath its surface, his men carved miles of tunnels, pillboxes, and gun positions, prepared to fight to the death. This episode tells the story of that buildup. The strategy, the doubts, the Japanese preparations, and the weight that fell on every Marine the night before the landings. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

The Philippines became the centerpiece of General Douglas MacArthur's promise to return. The Army was to lead, but when setbacks on Leyte bogged down operations, Marine aviation and artillery were rushed in. Within hours after their arrival, they were flying convoy cover, striking Japanese shipping, and dueling enemy aircraft. Despite crude airfields and poor coordination under Fifth Air Force control, Marines flew over 260 missions in their first few weeks. By campaign's end, Marine air had won Distinguished and Presidential Unit Citations, reshaped close air support doctrine, and proven indispensable. What began as reinforcement became central to victory, cementing Marine aviation's legacy in modern warfare. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

The 7th Marines landed on Peleliu under the command of Colonel Herman H. Hanneken. Veterans of Guadalcanal and Cape Gloucester, they now faced a new kind of hell. Their mission was to seize the island's eastern shore, then pivot south to clear Japanese positions threatening the airfield. Over weeks of unrelenting combat, they fought through blockhouses, mangrove swamps, and the notorious Bloody Nose Ridge, in brutal, close-quarters action. Acts of valor, like PFC Arthur J. Jackson's Medal of Honor assault, stood against staggering casualties, disease, and exhaustion. The episode follows the 7th Marines from their D-Day landing through the grinding fight inland, their eventual relief, and the debate that still surrounds whether Peleliu was worth the cost. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

In this episode, we examine the 5th Marine Regiment's role in the brutal Battle of Peleliu. As part of the 1st Marine Division, the 5th Marines were tasked with seizing the island's strategically vital airfield. They advanced across open terrain under withering fire, securing the airfield despite intense Japanese resistance and extreme environmental conditions. By mid-October, after nearly a month of combat, the 5th Marines were physically spent and heavily depleted.  ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

In this episode, we explore the brutal experience of the 1st Marine Regiment during the early days of Peleliu. Under relentless enemy fire, Marines fought their way across beaches and through rugged coral ridges against deeply entrenched Japanese defenders. They endured extreme heat, devastating casualties, and severe logistical challenges that tested their limits. In the fierce fighting at Peleliu, Marines showed remarkable bravery, repeatedly risking their lives to protect their fellow brothers. Although the Marines achieved critical early goals, their losses were so heavy that the regiment eventually had to withdraw. Their sacrifices made the critical difference, paving the way for other Marine units to finish the fight, especially the battle for the island's crucial airfield. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

Peleliu was part of the Allies' island-hopping campaign to capture key islands and build forward bases on the path to Japan. Expected to last only a few days, the battle instead turned into one of the Pacific War's longest and bloodiest fights. The island was strategically critical because of its airfield, needed for Allied operations and protecting General MacArthur's flank during his return to the Philippines. Japanese defenders, entrenched in sophisticated fortifications including caves, tunnels, and reinforced bunkers, fiercely resisted the Marine landings. The rugged coral terrain and oppressive heat further complicated operations, pushing Marine endurance to the limit. The 1st Marine Division, seasoned from previous campaigns at Guadalcanal and Cape Gloucester, faced intense close-quarter combat. Their resilience, adaptability, and courage under extreme conditions exemplified the brutal realities of island warfare, marking this battle one of the costliest and hardest-fought in Marine Corps history. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

After weeks of relentless fighting, Saipan fell into American hands. The strategic island of Guam was next, heavily reinforced and waiting. The enemy had fortified every possible landing spot, preparing meticulously for another bloody defense. Delays added frustration, but also time for crucial adjustments. On July 21, 1944, the Marines finally hit Guam's beaches under a storm of enemy fire, instantly facing familiar brutality: concealed bunkers, merciless artillery, and a stubborn enemy refusing to yield. Saipan's scars were fresh, and now Guam promised more of the same. Yet Marines fought forward with grim determination, knowing this island was key to turning American bombers loose against mainland Japan.  ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

With Saipan's beaches secured but far from safe, Marines now faced the brutal inland fight. The Japanese launched desperate tank assaults near Red Beach with the goal of driving Americans back into the sea. Marine bazooka teams and grenadiers met the threat head-on. By dawn, the cost was clear: hundreds of enemy dead, rising Marine casualties, and the realization that Saipan would be a grinding, bloody fight. Reinforcements landed, artillery emplacements expanded, and command began shifting ashore. With the beachhead now stable, the Marines prepared for the next brutal push inland toward ridgelines, sugar mills, and enemy strongholds. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

The Marines barely had time to catch their breath after Kwajalein before their attention shifted northwest to Enewetak Atoll. Four islands in particular stood as crucial targets, heavily defended by thousands of Japanese troops racing to build defenses strong enough to repel any invasion.  Initially, commanders planned the attack for months later, but fresh aerial reconnaissance and captured enemy maps showed that waiting would only strengthen Japanese defenses. With detailed intelligence and thousands of battle-tested Marines at their disposal, commanders swiftly made their decision: hit Enewetak immediately.  As Marines stormed beaches through heavy naval bombardment and air strikes, they quickly realized they'd underestimated the enemy strength—setting the stage for one of their toughest fights yet in the Pacific. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

At Kwajalein and Roi-Namur, months of rehearsals, better intel, and hard-earned Tarawa lessons came together. The 4th Marine Division, fresh off the boat from Pendleton, made its combat debut alongside Army units already blooded in the Aleutians. They landed under real air cover, backed by real logistics, and fought smart, clearing bunkers with tanks and torches instead of charging into fire. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

The initial assault was chaotic—coral reefs slowed the approach, landing craft were wrecked, and units came ashore under heavy fire. But by the second and third days, the situation began to change. Officers like Shoup, Edson, and Jones made key decisions, reinforcements came in, and tanks managed to cross the reef. Despite exhaustion and limited ground, the Marines pushed inland. Today's episode focuses on that shift—from securing the beach to pressing the attack. We'll look at how the 1st Battalion 8th Marines broke through, how Crowe and Jones coordinated flanking movements, and how tanks helped turn the momentum. We'll also cover the Japanese night assaults and the close-quarters fighting that defined the battle's turning point. Tarawa remained brutal, but these days marked the start of a hard-fought advance. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

By late 1943, the Allies had turned the tide in the Pacific, but one significant stronghold still loomed. In Japan's most critical South Pacific base, Rabaul served as a launch point for air and naval operations across New Guinea and the Solomons. Instead of a costly direct assault, Allied planners devised a strategy to neutralize Rabaul through isolation, cutting off its supply lines and rendering it ineffective.  Bougainville became the next step in this plan, providing airfields and a staging ground for the final push. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

By mid-1943, the Allies were advancing through the Solomons, pushing toward Rabaul. After securing Guadalcanal and New Georgia, their next target was Vella Lavella. Unlike previous battles, the Japanese opted to withdraw rather than defend the island outright, but the fight was far from easy. Marines, Seabees, and New Zealand forces faced logistical chaos, relentless air attacks, and fierce resistance from the remaining enemy troops. As U.S. forces established a foothold, Japanese commanders launched a last-ditch evacuation, leading to a violent clash. Vella Lavella proved the growing strength of Allied coordination, air superiority, and adaptability in island warfare. With the island secured, the path to Bougainville, and ultimately Rabaul, was open. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

The US Army's arrival brought reinforcements and a reorganization of American troops. New tactics, like flamethrowers and enhanced naval gunfire, were introduced, though terrain and enemy fortifications remained challenging. The 1st Marine Division, weakened by malaria and extended combat, was finally relieved and sent to Australia for some much-needed rest. We end the episode by touching on how Guadalcanal advanced amphibious warfare doctrines and technology and improved coordination between military branches.

This episode dives into the strategic reorganization of American forces during the Guadalcanal campaign. The 164th Infantry and 7th Marines, positioned in the East Sector, tackled the harsh terrain as they encircled the enemy. Company B of the 8th Marines in the West Sector was crucial in securing vital artillery positions. Central to the operation's success was the 2nd Raider Battalion. Known for their bold patrolling tactics, their objective was to ambush and attack the enemy unpredictably. Yet, despite their strategic prowess, some Japanese forces slipped away due to communication and coordination hiccups. We'll also spotlight the pivotal naval and air battles that cut off Japanese supply lines, focusing on the decisive role of American aviation based at Henderson Field. This relentless air pressure prompted Japan to shift its strategy from trying to recapture Guadalcanal to sustaining and extracting its forces. Additionally, we'll cover the deployment of war dogs and the crucial reconnaissance missions undertaken by the 2nd Raider Battalion.
