The mid-19th century in Central America was a period marked by political instability and external interventions, none more dramatic than the saga of William Walker, an American mercenary who sought to establish a personal empire. His ambitions clashed repeatedly with the nascent nations of the region, leading to pivotal conflicts like the Battles of Rivas.

The First Battle of Rivas: June 29, 1855

Before the more widely recognized second engagement, the town of Rivas, Nicaragua, first became a battlefield on June 29, 1855. This initial clash saw William Walker's burgeoning forces, primarily American adventurers often referred to as filibusters, confront the forces of the Legitimist government of Nicaragua, then under the leadership associated with Fruto Chamorro Pérez. Walker had arrived in Nicaragua in May 1855, ostensibly invited by the Liberal faction, engaged in a civil war against the Legitimists. His objective was clear: to gain control, first by supporting the Liberals, and eventually to establish his own dominance, even aiming to resurrect slavery in the region.

During this first encounter in Rivas, Walker's forces, though spirited, faced a determined resistance. While they managed to inflict casualties, they ultimately failed to secure a decisive victory or hold the town. This battle served as an early test for Walker’s military capabilities and signaled the beginning of a prolonged struggle for control of Nicaragua, hinting at the larger conflict that would soon engulf Central America.

The Second Battle of Rivas: April 11, 1856

Less than a year later, on April 11, 1856, Rivas would once again be etched into the annals of Central American history, this time hosting a far more consequential and brutal engagement. This Second Battle of Rivas pitted the unified forces of Costa Rica, led by their resolute President and Commander-in-Chief, General Juan Rafael Mora Porras, against the now more entrenched Nicaraguan forces of William Walker. By this point, Walker had consolidated significant power, even proclaiming himself President of Nicaragua, an act that deeply alarmed neighboring states and ignited what became known as the "National War" or "Filibuster War."

The Costa Rican government, under President Mora, viewed Walker’s presence and ambitions as a direct threat to their nation's sovereignty and the stability of the entire Isthmus. Consequently, Costa Rica declared war on Walker's regime, leading to a march into Nicaraguan territory. The battle itself was a fierce struggle for control of Rivas. Walker's forces were well-positioned, and the fighting was intense, particularly around strategic points like the local church. Costa Rican soldiers fought with exceptional bravery, ultimately forcing Walker's filibusters to retreat from the town, though at a significant cost in lives for both sides.

This battle is particularly remembered in Costa Rican historical narratives, partly due to the legendary act of heroism attributed to Juan Santamaría, a drummer boy who, according to tradition, bravely set fire to a strategic stronghold held by Walker's men, albeit at the cost of his own life. While the immediate tactical victory was claimed by Costa Rica, the aftermath brought its own tragedy. The returning Costa Rican army was ravaged by a severe cholera epidemic, which claimed far more lives than the battle itself, illustrating the brutal realities of warfare in the 19th century. Nevertheless, the Second Battle of Rivas was a critical turning point, marking the beginning of the end for William Walker's dominion in Central America.

Understanding the Context: William Walker and the Filibuster War

To fully grasp the significance of the Battles of Rivas, one must understand the ambitious figure of William Walker and the broader conflict he instigated. An American physician, lawyer, and journalist, Walker harbored grandiose visions of establishing an English-speaking empire in Latin America, often with the intent of reintroducing slavery. His ventures were part of a larger phenomenon known as "filibustering"—private military expeditions unauthorized by the U.S. government but often tolerated due to prevailing expansionist sentiments.

His arrival in Nicaragua in 1855, initially as an ally to one faction of a civil war, quickly escalated into a bid for personal power. His actions threatened the delicate balance of power in Central America, prompting a united response from the region's nations, including Costa Rica, Guatemala, El Salvador, and Honduras. These combined efforts culminated in the defeat of Walker in 1857, bringing an end to a tumultuous chapter in Central American history.
