History of the Marine Corps

In December, Marines fought one of their toughest battles on Bougainville—securing Hellzapoppin Ridge. This heavily fortified enemy stronghold loomed over Marine lines, threatening the expanding perimeter. For over a week, the fight raged in the thick jungle, where Marines faced relentless enemy fire and near-impenetrable defenses. Artillery barrages, airstrikes, and unyielding infantry assaults eventually broke the Japanese hold, but the cost was high. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

In November 1943, U.S. Marines fought a brutal series of battles on Bougainville, pushing to secure key high ground. One of the toughest fights was at "Grenade Hill," where Marines faced relentless grenade attacks before the Japanese finally abandoned their position. By the end of November, the Marines had secured the high ground, breaking Japanese resistance and ensuring control over the expanding perimeter. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

By early November 1943, the Japanese launched a desperate counteroffensive to reclaim Bougainville. Their plan called for a large-scale infiltration behind Marine lines, followed by a full assault. The Marines' quick response and overwhelming firepower shattered the enemy's ambitions. Artillery and airstrikes devastated Japanese forces, while the Raiders and 9th Marines held the crucial Piva Roadblock against repeated attacks. The battle saw acts of incredible bravery, including the sacrifice of PFC Henry Gurke. By the end of November, the Marines had secured their perimeter, and positioned themselves for the next phase of the Bougainville campaign. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

This episode dives into the planning and execution of the amphibious assault at Cape Torokina. From complex logistical challenges to the intense combat on the beaches, we cover how Task Force 31 and IMAC coordinated this massive operation. We also discuss the key engagements that followed the landing, including Sergeant Robert A. Owens' heroic assault on a fortified 75mm gun position, the bloody close-quarters combat that unfolded, and the strategic countermeasures taken to repel Japanese counterattacks. ************* 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.

By July 7, the Marines' push toward Enogai had slowed to a crawl. Thick jungle, relentless enemy fire, and brutal terrain turned every step into a fight. Runners risked their lives to keep communication going, while corpsmen worked tirelessly to save the wounded. When the Raiders captured a map of enemy defenses, Liversedge saw his chance. The 1st Raider Battalion launched a full-scale assault, smashing through machine-gun nests and mortar fire. By day's end, Enogai was theirs, cutting off a key Japanese supply line. But the cost was high, and the battle for New Georgia was far from over. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

The Solomon Islands campaign was a turning point in the Pacific War, pushing the Marines to their limits in a relentless battle against both the Japanese and the unforgiving environment. This episode focuses on the critical role the Marines played in the grueling fight for New Georgia, where dense jungles, endless rain, and a determined enemy tested their resolve. As part of Operation TOENAILS, the Marines spearheaded daring assaults, pivotal for advancing the strategically vital Munda airfield. Alongside Coastwatchers and local guides, the Marines relied on bravery, ingenuity, and sheer grit to overcome fortified enemy positions and treacherous terrain. These hard-fought victories shaped the outcome of the New Georgia campaign and set the stage for the eventual Allied push toward Japan. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

For months, the Marines endured brutal combat, disease, and exhaustion on Guadalcanal. The 1st Marine Division, depleted by malaria and months of fighting, finally got their relief. The Americans, strengthened by fresh troops, moved in, bracing for a tough battle. But the Japanese had other plans. While the Americans prepared for a fight, the enemy was already disappearing into the night. This episode covers the final days of the Guadalcanal campaign—the brutal battle for Hill 27, the Marines' last engagements, and the lessons that shaped future Pacific battles. Guadalcanal wasn't just a victory—it was the moment that forced Japan onto the defensive for the rest of the war. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

Guadalcanal was a campaign defined by endurance. By November, the tide had shifted in favor of the Americans, but victory was far from certain. The plan was to encircle and eliminate the remaining Japanese forces, a strategy that seemed straightforward on paper but proved far more challenging to execute. This episode covers the final push to trap the enemy—coordinated attacks from the 7th Marines, the 164th Infantry, and Carlson's Raiders. As the Marines fought through the jungle, the Japanese slipped through gaps in the lines, turning what could have been a decisive blow into another grueling fight. We'll also look at the role of naval power in the campaign's outcome, the challenges of coordinating Army and Marine units, and the growing pains of joint operations in the Pacific. This is the story of the final weeks before Guadalcanal was secured—and the men who paid the price to make it happen. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

By mid-October, the situation on Guadalcanal had reached a breaking point. Malaria swept through the ranks, sidelining hundreds of Marines each week. Combat-weary and outnumbered, they faced relentless Japanese assaults aimed at seizing key river crossings. Holding the Matanikau was critical—not just for defense, but for survival. As both sides scrambled for reinforcements, the battle lines shifted, and the Marines found themselves locked in brutal engagements across the island. This episode covers the mounting challenges they faced, the strategic importance of the Matanikau, and the desperate fight to hold Guadalcanal. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

By late August 1942, the fight for Guadalcanal had become a brutal test of endurance. The Marines had repelled Ichiki's reckless assault, but the Japanese weren't finished. Each night, enemy destroyers—nicknamed the "Tokyo Express"—delivered fresh troops, while air raids and naval bombardments pounded Henderson Field. The Marines, low on supplies and outnumbered, held their ground through sheer determination. Meanwhile, the Cactus Air Force fought a relentless battle in the skies, downing enemy planes despite primitive conditions. As Vandegrift reinforced his perimeter, Edson's Raiders braced for a desperate stand at Bloody Ridge, and Chesty Puller led aggressive patrols against Japanese forces near the Matanikau River. Offshore, the Battle of Cape Esperance shifted the balance at sea. This episode covers the brutal battles, tactical shifts, and raw courage that defined Guadalcanal. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

With the Navy pulling out, the Marines on Guadalcanal were left in a bad situation. General Vandegrift had no choice but to tighten the perimeter around Lunga Point, focusing all defenses on the airfield. Marine engineers struggled to keep the airfield operational, facing daily air raids and supply shortages. We'll close the episode with the Marines bracing for the Battle of the Tenaru, their first large-scale ground fight of the campaign. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

While the previous episode followed the Marines storming Tulagi, this one shifts to Beach Red, where the 1st and 5th Marines landed to secure the island's key objective: Henderson Field. We'll get into the initial naval and air bombardment, the landing process, and the eerie lack of Japanese resistance at the shoreline. As the Marines pushed inland, they quickly realized Guadalcanal wouldn't be an easy fight. The terrain was dense, the jungle unforgiving, and while the Japanese weren't visible at first, they were waiting—ready to strike. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

While the main invasion force stormed Guadalcanal, a smaller but equally critical battle unfolded on Tulagi. As Marines waded through chest-deep surf, they found themselves facing an enemy that would not surrender. Fighting through thick jungle and jagged ridgelines, they encountered machine-gun nests, sniper fire, and relentless counterattacks. The battle for Tulagi would turn the island into a brutal proving ground for the Marines. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

Before Marines stormed beaches in the Pacific, they had to prove they were worth keeping around. When steamships made close-quarters ship combat obsolete, the Marine Corps was nearly scrapped. Their old mission vanished overnight. This episode tells the story of how Samoa helped save the Corps. After Pearl Harbor, Samoa looked like Japan's next logical target. The Marines were sent to hold the island at all costs. Marines fortified beaches, built airfields, trained a Samoan reserve battalion, and turned the island into a launch point for operations across the South Pacific. Samoa never saw major combat, but it proved Marines could build and defend forward bases anywhere in the world. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

Most people don't think of Iceland when they think about Marines in World War II. No battles, no amphibious landings, no dramatic last stands. Just a wind-battered volcanic island, frozen mud, sideways rain, and Marines pulling security in a place where the sun never set—and nothing ever happened. This episode dives into the forgotten deployment that tested morale more than marksmanship. We'll talk about the midnight sun landings, the endless working parties, and how Marines turned an unglamorous garrison mission into a blueprint for readiness. There were no medals for standing watch on a glacial ridge—but the small-unit leadership, the discipline, and the quiet grit these Marines showed laid the foundation for what came next in the Pacific. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

This episode tells the story of the rocky island fortress where the 4th Marines made their final stand. After surviving weeks of retreat, jungle fighting, starvation, and disease on Luzon, the Marines fell back to Corregidor alongside sailors, Philippine Army cadets, and general-duty troops. Undermanned and outgunned, they turned this small island into a last line of defense against overwhelming Japanese firepower. We cover how the Marines trained sailors to fight like infantry, repurposed aircraft bombs into improvised mines, and held a fractured defense line with mixed units from over 50 commands. Bombed daily, under constant artillery fire, and surviving on a third of a ration, they dug in, determined to hold. When the Japanese landed, the Marines unleashed everything they had, but it wasn't enough. The island fell—but not quietly. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

This is the second episode covering the global unraveling that led to America's full entry into World War II. After Germany invaded Poland, Europe spiraled into chaos. Hitler pushed for control of Norway to secure critical resources and the lightning-fast German invasion of France exposed the flaws in Allied assumptions and defenses. With France collapsed and Britain barely holding on, Hitler turned east, launching the largest land invasion in history against the Soviet Union. At the same time, Italy entered the war, expanding the conflict to North Africa and the Mediterranean. While Europe burned, Japan eyed Southeast Asia's oil-rich territories. Roosevelt's oil embargo pushed Japan closer to war, and the U.S. began preparing its Pacific defenses. By the end of 1941, Axis forces held most of Europe and were advancing across Asia. This episode lays out how the global conflict widened and set the stage for Pearl Harbor, the fall of the Philippines, and the brutal Pacific campaign that followed. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

In this episode, we follow how the Marine Corps went from doubting pilots to building one of the world's deadliest air-ground teams. Aviation started as a sideshow and something most Marines didn't take seriously. But by the 1930s, Marine pilots had revolutionized air tactics.

When Marines returned home after World War I, they stepped into a country ready to celebrate them as heroes. Parades filled city streets, families welcomed them with open arms, and it seemed like America couldn't thank them enough. But this enthusiasm was short-lived. Within months, a sense of disillusionment set in, replacing cheers and excitement with a stark reality check on what the war had truly cost. Soon, that collective sense of pride turned into doubt, questioning whether the glory earned in combat was worth the terrible price Marines paid. This shift deeply impacted the Corps, leaving it struggling to fill its ranks and maintain morale as America moved toward isolation. In this episode, we'll explore how the Marine Corps fought to adapt in the face of a shrinking force, outdated promotion policies, and fading public support. From Hollywood's depiction of war's bitter realities to the Corps' desperate pivot toward sports and education, you'll see how the Marines grappled with a nation eager to leave war, and warriors, in the past. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

This episode closes the book on World War I with the moment Marines had been waiting for: the end. After years of brutal fighting, the armistice was real, and Marines on the Meuse were among the last to get the memo. Even as German officers crossed no-man's-land with word of peace, Americans were still taking casualties. We walk through the confusion, the celebration, and the quiet bitterness that followed. Then came the long march into Germany, the occupation, and finally, the return home. But not everyone made it back the same. This is the story of how the war ended and what came after. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

This episode covers one of the Marine Corps' most overlooked, but bloodiest battles of World War I: Blanc Mont Ridge. After their success at Saint Mihiel, the 2nd Division was called up again, this time to break through heavily fortified German positions in Champagne. Lejeune fought to keep the division intact and led them into nightmarish terrain, even by WWI standards. We follow the 5th and 6th Marines as they charge uphill through open fields, tangled trenches, and relentless machine-gun fire. It was a brutal fight, with chaos, heroism, Medal of Honor moments, and a full-blown retreat. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

This episode picks up after Belleau Wood, as the Marines shift from defense to offense in the Aisne-Marne Offensive. With hard-won respect from Army and Allied commanders, the 4th Marine Brigade joined the push to crush Germany's last major offensive. Planning was a mess.

Still, they hit the line right on time, under cover of a short but brutal artillery barrage. A chaotic, multi-national charge follows through open fields, tangled forests, and fortified German positions. It's Belleau Wood all over again, just bigger. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

This episode marks the beginning of the Marine Corps' legendary role in World War I. After months of training and frustration, the 4th Marine Brigade was finally called into action.

Outnumbered and outgunned, Marines held the line against Germany's elite forces. As the Germans pushed hard toward Paris, the Marines dug in and counterpunched.

In 1916, the Marine Corps was small, scattered, and barely on the Navy's radar for large-scale war. This episode shows how that changed. We dive into the Corps' explosive growth, the birth of its aviation wing, and the fight for combat relevance in Europe. From Parris Island tents to French trenches, we track how thousands of volunteers turned into hardened Marines. We also look at the tension between Navy leadership and the Corps over where Marines should serve, and how that tension shaped everything from battlefield assignments to post-war legacy. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

By 1914, one shot was all it took to ignite the explosion. ************* Visit HistoryoftheMarineCorps.com to subscribe to our newsletter, explore episode notes and images, and see our references.

In our last episode, we wrapped up the story of the Marine Corps' campaign in the Philippines. This week, we shift focus to another major deployment at the turn of the 20th century: China.
