The Banana Wars E75 Sandino’s War: The Long Fight for Nicaragua
This episode highlights the peak of U.S. military intervention in Nicaragua, where the Marine Corps carried the burden of stabilizing a nation caught in continuous civil war and political breakdown. Initially sent to disarm warring factions and oversee fair elections, Marines were soon thrust into full-scale counterinsurgency against Sandino’s growing rebel force.
Political divisions in Washington, exhaustion among American troops, and the unreliability of Nicaraguan government forces complicated the mission. By the early 1930s, U.S. leaders began shifting responsibility to the Nicaraguan National Guard. The last Marines left in 1933, ending a two-decade-long intervention.
Though the effort failed to deliver lasting peace, it solidified the Marine Corps’ identity as a rapid-response force and shaped its doctrine on small wars and irregular combat. Lessons that would carry forward into the next generation of global conflict.
The Banana Wars E74 Butler’s Baptism: The 1912 Intervention in Nicaragua
This episode tracks the deepening U.S. military involvement in Nicaragua during the early 20th century. What started as a limited response to protect American property evolved into a full-scale intervention. Under officers like Smedley Butler and Joseph Pendleton, Marines carried out combat operations, secured key infrastructure, and enforced U.S. foreign policy with both force and diplomacy.
From retaking towns and railroads to battling entrenched rebels at Coyotepe Hill and beyond, the Marines showcased their rapid deployment and operational flexibility. Political corruption, civil unrest, and deep resentment toward U.S. influence continued to fuel revolution. As Nicaragua spiraled into deeper conflict, the U.S. increased its military presence, eventually committing thousands of troops, naval support, and air power.
The Banana Wars E73 Boots in the Cane Fields: Marines and the Sugar Wars of Cuba
What began as a limited intervention in Cuba escalated into a long-term pattern of rapid Marine deployments throughout Latin America. From the 1906 occupation of Cuba to repeated landings in response to political unrest, Marines proved capable of stabilizing volatile regions with limited resources. Their missions expanded from protecting American property to enforcing U.S. foreign policy, often in service of economic interests.
The Corps also matured operationally, executing coordinated deployments, adapting to complex political situations, and managing civil-military affairs with discipline. By the time Marines were sent to Nicaragua in response to revolution and the execution of U.S. citizens, it was clear that the Marine Corps had become the tool of choice for fast, flexible, and forceful action abroad.
The Banana Wars E72 Veracruz and the Rise of the Expeditionary Force
This episode covers a critical turning point for the Marine Corps and American foreign policy. After the fall of Mexico’s President Madero and the rise of Huerta’s regime, the U.S. launched a full-scale military response, culminating in the 1914 occupation of Veracruz. Marines led the charge, executing urban combat, securing key infrastructure, and even handling civil tasks like sanitation.
The U.S. deepened its involvement in Cuba under the Platt Amendment, using Marines to stabilize a fractured political system and protect American interests. These back-to-back interventions marked the growing use of Marines as a flexible, fast-response force for U.S. foreign policy. It was the start of a new identity for the Corps, one shaped by intervention, occupation, and increasing global reach.
The Banana Wars E71 Doctrine Backed by Firepower: The Monroe Legacy in Latin America
This episode marks the beginning of a new era for the Marine Corps. Between 1898 and World War I, Marines were no longer just a shipboard force. They were central to U.S. foreign policy in Latin America, especially during the Banana Wars. From Panama to Mexico, Marines became the go-to unit for rapid intervention, counterinsurgency, and stability operations.
Their efforts helped shape the U.S. role in the region and laid the groundwork for modern expeditionary doctrine. The Marine Corps had found its niche and over the next few episodes, we’ll break down how those missions played out, one country at a time.
Spanish American War E70 Yellow Journalism, Red Blood
As the 19th century closed, the Marine Corps transitioned from a small peacetime force into a rapidly growing expeditionary unit. The Spanish-American War was the catalyst.
Marines executed the first amphibious assault in Cuba, secured Guantánamo Bay, and played a role in key operations across the Pacific.
This episode tracks the shift on how the Corps went from being a marginal asset to a key player in America’s emergence as a global power. It wasn’t a long war, but its legacy reshaped the military, set new standards for combat readiness, and solidified the Marine Corps' identity as the nation’s forward-deployed force.
The Gilded Age E69 The Making of the Modern Marine Corps
This episode covers an often overlooked period of Marine Corps activity during the Gilded Age. While the nation focused on industry and expansion, Marines were deployed globally, supporting U.S. interests, protecting trade routes, and enforcing treaties. In Panama, they were involved in repeated interventions to stabilize a region critical to future canal plans.
At home, the Corps faced low morale, slow promotions, poor infrastructure, and outdated equipment. The Corps stayed active, adapted when needed, and proved its value through consistent performance in uncertain conditions.
The Gilded Age E68 Gold-Plated Peace: Marines in the Age of Industry
After the Civil War, the Marine Corps entered its quietest era. There were no major wars, little funding, and almost no growth. But quiet didn’t mean inactive.
While the U.S. focused on rebuilding and chasing economic progress during the Gilded Age, Marines adapted. They manned ships, patrolled foreign ports, broke up riots at home, and took part in some of the earliest examples of U.S. global presence. At home, they helped enforce federal law and saw the beginnings of modernization in weapons, uniforms, and training.
Civil War E67 Fire and Sand: Marines at Fort Fisher
This episode covers the final months of the Civil War, focusing on the Marine Corps' role at Fort Fisher. It was the last major Confederate stronghold on the coast, and its fall marked the beginning of the end for the South. Marines were tasked with supporting a large-scale amphibious assault, but confusion, poor communication, and leadership breakdowns turned the operation into a disaster.
After Fort Fisher, the Confederate Marine Corps all but collapsed. The war would end weeks later at Appomattox, followed by Lincoln’s assassination. In the aftermath, the Marine Corps faced serious challenges including desertion, low morale, and a changing national mission. Although often overlooked, Marines made a meaningful impact in the Civil War, and this episode highlights their contribution as the nation transitioned into a new era.
Civil War E66 Filling Henderson’s Shadow: The Struggle for Vision After Harris
This episode covers a critical turning point in the history of the Marine Corps during the Civil War. When Commandant John Harris died, Gideon Welles had to decide who would lead the Corps through one of the most chaotic moments in American history. Internal politics, personal rivalries, and competing visions for the Corps' future all played a role in the selection of Colonel Jacob Zeilin as the new Commandant.
The episode tracks the evolution of the Corps' role in major military operations, highlighting the actions of Marines during the battles of Mobile Bay, the defense of the railroads in Maryland, and the brutal fighting around Honey Hill and Fort Fisher. Marines were rarely the focus of Civil War history, but their contributions were vital.
