1631: When Caragans Wiped Out Spanish Power at Fort San Jose

5 November 2025 Feature | Surigao Historical Society | Local History

The Blood Tide: When the Caragan Uprising Brought Down the 'Fortress of San Jose'

The 17th century was a time of iron and faith in Mindanao, dominated by the relentless expansion of the Spanish Empire into the region known as Caraga. The hub of Spanish might on the eastern coast was the formidable Fort San Jose in Tandag, a military rampart intended not only to intercept raiding Muslim forces but also to contain the warlike local inhabitants—the Caragans.

Yet, the year 1631 brought an astonishing defeat, a moment so decisive that Spanish historians later deemed it "one of the darkest pages in the history of the province of Caraga". It was a bloody assertion that the native people possessed both the fighting spirit and the skill to challenge the supposedly invincible European power.

The Stone Sentinel of Tandag

Built in 1609, the Fort of San Jose stood as a bold symbol of colonial dominance. Its construction, often relying on forced native labor, utilized massive stone masonry. The fort was strategically triangular, boasting three bastions, protected by a moat on two sides, while the third wall met the sea. It housed canons of various calibers and sufficient weaponry for defense, serving as a critical sentinel against hostile forces.

The Spanish presence, however, was marked by arrogance and oppression, feeding a deep well of native resentment. The local populace was subjected to forced labor and compelled to pay tributes to the military and civil government. This volatile situation, combined with "nativist reflexes," led to widespread restlessness, characterized by "murders, thefts, and insolences" among the natives.

The Spark of Vengeance

The eruption of hostilities was ignited by the iron-fisted rule of Captain Pedro Bautista, who commanded the fort and launched punitive raids. During one such expedition in 1631, Bautista captured seven slaves.

A local chief named Dumblag heroically intervened, freeing all the captives. Enraged by this open defiance, Captain Bautista put Dumblag in chains.

This insult proved fatal to Spanish authority. Chief Valintos, a relative of Dumblag, swiftly sought revenge, leading an immediate counter-attack that resulted in the death of Captain Bautista and the expedition’s chaplain, Fr. Jacinto de Jesus Maria. Sensing a pivotal shift, other local chiefs who had previously maintained friendly relations with the Spanish rose in arms against the Crown.

The localized revolt found powerful regional support; the sources suggest that Valintos was encouraged by Sultan Corralat (Kudarat). For Kudarat, the isolated Fort of Tandag was a crucial target in his nationalistic struggle, representing a link in the chain of Spanish coastal defenses meant to box in Muslim forces.

The Fort Falls and the Tide Spreads

By 1631, the Caragan warriors—comprising largely the Manobos and Mandayas who were fierce fighters—successfully overran and completely wiped out the entire Fort of San Jose in Tandag.

The rebellion was not confined to the former capital; it flared up throughout Caraga territory. In Tago and Bacuag, the rebels attacked convents and killed missionaries. On July 22, 1631, at Bacuag, Zancalan, the son of the notorious rebel leader Mangabo—known as the "crocodile of Tago"—killed Fray de San Fulgencio and several others.

Mangabo’s character embodied the complex and sometimes terrifying clash of cultures. He miraculously spared Fray Lorenzo de San Facundo, but only after performing a gruesome ritual known as Sandugo. Mangabo loosened breeches stolen from a convent, wounded himself, and collected his blood in a dish mixed with wine. After drinking some, he swore an inviolate oath by embracing Father Lorenzo and placing his own turban on the priest’s head, establishing him as a ritual son. Meanwhile, the violence continued; another priest, Fr. Pedro de San Antonio, was speared in Surigao and his body thrown into the river.

An initial Spanish relief expedition dispatched to Tandag was immediately repulsed, losing its commander and chaplain, whose bodies were left on the beach.

Retaking the Ruins

It was only after a fierce fight led by a second Spanish contingent under Juan de Chavez that Tandag was eventually retaken and the fortress re-occupied. The rebellion, however, continued in other parts of the province.

The conflict was ultimately settled not by military subjugation, but through diplomacy. The uprising ended in a negotiated peace treaty, mediated by religious figures, including Father Jose de la Anunciacion and Fray Jacinto.

Although the fort was later rebuilt, the 1631 rebellion served as a powerful testament to the resilience of the Caragan people and provided Kudarat with a momentary advantage, permanently marking Tandag as a vulnerable, isolated outpost in the Pacific. The memory of this destructive native uprising would linger in Spanish colonial records for centuries.

5 Questions to Spark Your Curiosity

Identity and Reputation: The sources describe the 17th-century inhabitants of the eastern coast as fierce and "warlike," leading to the widely feared identity of the "Caragans". How does this historical reputation of indomitable resistance shape the cultural memory and sense of identity among modern Surigaonons today?
Geopolitical Strategy: The fall of Fort San Jose was supported by Sultan Kudarat, who recognized Tandag’s importance in the broader Muslim-Spanish conflict. How did this interconnection between local upland revolts and the Sultanates in the south define the true boundaries of colonial warfare in Mindanao during this era?
Diplomacy and Power: The sources confirm the revolt ended in a "negotiated peace treaty" rather than a total military defeat of the natives. What leverage did the Caragan chiefs gain through this treaty, and how might this diplomatic victory have influenced subsequent Spanish policies in the Caraga region?
Colonial Memory: Spanish historians categorized the loss of Fort San Jose as "one of the darkest pages" in Caraga's history. If the story were told from the perspective of Chief Valintos or Mangabo, how would this event be characterized, and what does this shift in perspective reveal about whose history is preserved?
Cultural Paradox: Mangabo, the "crocodile of Tago," killed Spanish friars but spared another by performing the Sandugo (blood compact). How do these powerful, ritualistic acts illustrate the profound cultural gaps and spiritual complexities the Spanish missionaries faced in trying to impose a singular Christian order?
