From Yauco to Las Marias: A recent campaign in Puerto Rico by the Independent Regular Brigade under the command of Brig. General Schwan

In Short

This book serves as a firsthand historical record of the Independent Regular Brigade’s campaign in western Puerto Rico in 1898. Led by Brigadier General Theodore Schwan, the brigade maneuvers from Yauco toward Mayaguez and Las Marias, engaging Spanish forces in a series of swift, decisive actions. More than just a regimental log, the work blends tactical reporting with the candid, often cynical observations of a professional soldier. It has remained a significant primary source because it captures the visceral reality of late-nineteenth-century warfare and the immediate post-war assessment of the island’s potential for American commerce.

The Story

The narrative begins at the Yauco rendezvous, where the Independent Regular Brigade gathers under General Schwan. The author, a member of Light Battery "D," immediately establishes the professional ethos of the soldiers, distinguishing their disciplined, stoic approach from the volunteer units of the era. The brigade’s mission is clear: drive the Spanish out of the western part of the island while minimizing casualties and maintaining rigorous order.

The march begins in early August. The column moves through the lush, mountainous terrain toward Sabana Grande, and then on to San German. The author paints a vivid, unvarnished picture of the infantryman’s life—the constant struggle with tropical heat, the monotony of hardtack, and the occasional, awkward interactions with local inhabitants. As they press toward Mayaguez, the tension mounts; scouts report a large Spanish force ahead.

The campaign reaches its climax at the engagement at Hormigueros on August 10. The author details the battlefield topography, noting the "pop of rifles" and the surprising ineffectiveness of Spanish marksmanship. The engagement is brief and largely devoid of the high-drama glory typical of military fiction; it is instead a methodical, professional maneuver. After a brief skirmish, the Spanish retreat toward Las Marias. The brigade enters Mayaguez in triumph, though the soldiers find themselves unceremoniously camped in a swampy bowl outside the city, left to grumble about their lack of pay and the comparative wealth of the volunteers stationed nearby.

The final military push occurs shortly thereafter at Las Marias. Colonel Burke leads a force to intercept the retreating Spanish, resulting in a one-sided skirmish that is cut short by the notification of a general truce. The author expresses a palpable, if dry, disappointment that the "shooting" stopped just as the brigade had hit its stride. Following the cessation of hostilities, the story shifts from military action to administrative observation. The final chapters detail the occupation of the territory, with the author offering an unsentimental, often harsh appraisal of the local populace, labor conditions, and the potential for agricultural investment. The book concludes with official reports and appendices, cementing the campaign’s place in the broader history of the conflict.

How It Unfolds

The rendezvous at Yauco The brigade assembles in a mountain-set town of 15,000, establishing the professional character of the officers and the specific orders to clear the western region. The author contrasts the disciplined, career soldiers with the volunteer regiments, setting a tone of professional pride.

The march to San German The column moves through the countryside, where the men contend with extreme heat and a diet of hardtack. The author describes the daily rhythm of the march, from the "dusky" women offering water to the invention of new, bitter nicknames among the weary soldiers.

The engagement at Hormigueros The brigade encounters the Alphonso XIII Regiment near a sugar-mill and a wooden bridge. The fighting is described as a matter-of-fact, almost mechanical affair where the lack of traditional "melodrama" reveals the true, unvarnished nature of a modern skirmish.

The occupation of Mayaguez The troops enter the city with colors flying, only to find themselves relegated to a swampy campsite outside the city limits. Here, the narrative captures the frustration of soldiers who are prohibited from entering the city, watching from afar as the volunteers enjoy the local amenities.

The pursuit to Las Marias The brigade pushes forward to catch the retreating enemy, culminating in a final, brief engagement. The announcement of the peace treaty arrives as an unwelcome interruption, leaving the men to contemplate their service as the conflict draws to a sudden close.

The assessment of the territory The campaign concludes with observations on the island’s economy, labor, and geography. The author provides a cynical evaluation of the local people and an investor’s guide to the potential profits in coffee, sugar, and vanilla production.

The People

General Theodore Schwan emerges as the central figure—a decisive, meticulous, and austere commander who focuses entirely on the professional execution of his orders. He is portrayed as a man who values efficiency above all else, exemplified by his ability to maintain order despite the lack of pay for his men.

Captain Macomb of the Fifth Cavalry is presented as the romantic ideal of a soldier, described as a "Custer without the vanity." He serves as a contrast to the rest of the weary brigade, a figure who commands attention through his stature and gravitas, yet remains entirely focused on his duty.

Colonel I.D. DeRussy and Lieutenant-Colonel Burke represent the leadership of the Eleventh Infantry. DeRussy is characterized by his "ministerial drawl" and dry wit, while Burke is the "impetuous and fiery" subordinate. Together, they provide a stable command structure that ensures the brigade’s success.

Lugo Vina, the leader of the native scouts, is depicted as a "swarthy, wizened little Puerto Rican" whose silence and force of character earn him the respect of the brigade. He represents the crucial, yet often overlooked, local intelligence that allowed the American column to navigate and succeed in the challenging terrain.

In Its Own Voice

"We were intensely voluble or silent by turns, and invented new nicknames for each other, which were so apt, spite of being touched with bitterness, that they stuck forevermore."

The author describes the psychological state of the men during the arduous, repetitive march through the Puerto Rican mountains.

"A striking feature of the engagement was the thoroughly matter-of-fact manner in which both officers and men went about their work."

The author reflects on the lack of heroics and the professional, almost bureaucratic atmosphere that defined the skirmish at Hormigueros.

"If there were any demand for their services, which there isn't, they would not be able to command anything approaching the standard of wages usual in the United States."

This blunt assessment follows the author's analysis of the island's labor market and the limited opportunities for American skilled laborers.

What It's Really About

This book is a study of the American military machine at the turn of the century, capturing the transition from the romanticized view of 19th-century combat to the industrial, professionalized reality of the 20th century. It explores the inherent tension between the "civilizing" mission promised by General Miles’s proclamations and the gritty, often brutal realities of occupation. Beneath the tactical descriptions, the text grapples with the question of whether a professional army is a tool for liberation or an instrument for economic acquisition. The author’s frank, frequently harsh views on the local population highlight the colonial attitudes of the era, revealing the deep-seated prejudices that underpinned the American administration’s approach to its new territory.

Why Read It Today

Readers with an interest in military history or the Spanish-American War will find this account invaluable for its lack of modern filters. It is a rare glimpse into the professional soldier’s experience—not the volunteer’s excitement or the politician’s rhetoric, but the day-to-day existence of those who carried out the campaign. The writing is precise and descriptive, capturing the sensory details of the march, the frustration of the swamp-camps, and the strange, quiet tension of modern combat.

However, a contemporary reader must approach the book with the understanding that it is a product of its time. The author’s attitudes toward the Puerto Rican people are condescending and frequently severe, reflecting the racial and colonial biases common to the period. The book does not attempt to be objective; it is a soldier’s perspective, written with a dry, cynical wit that often borders on the biting. If you can move past the period-specific attitudes, the book offers a fascinating, granular look at a forgotten campaign. It feels remarkably immediate, and the author’s sharp eye for detail—from the smell of the canned beef to the sight of the flag—ensures that the reality of the 1898 expedition remains vivid long after the final page is turned.
