The Antonio de Vea Expedition and the Loss of Sixteen Men at Evangelistas Islets (1676)
On February 17, 1676, disaster struck the Spanish exploration of Patagonia's remote fjords when sixteen men serving under Pascual de Iriarte were lost at the Evangelistas Islets, the treacherous rocks guarding the western mouth of the Strait of Magellan. Their deaths marked a somber episode within the larger Antonio de Vea expedition of 1675–1676, the most ambitious Spanish effort yet to survey the southern coasts of Chile and confirm or deny rumors of English encroachment. Though the expedition ultimately achieved its strategic goal of dispelling fears of a foreign base, the tragedy at Evangelistas underscored the brutal risks the crown's sailors faced in one of the world's most inhospitable maritime environments.
A Response to Fears of English Rivals
By the mid-1670s, Spanish colonial officials in Peru and Chile had grown increasingly anxious about the possibility that England or another European power might establish a foothold in the labyrinthine channels of Patagonia, a region largely unmapped by Spanish authorities despite more than a century of nominal claim to the Pacific coast. Memories of Francis Drake's incursions a century earlier, combined with fresh rumors of foreign ships spotted near the Strait of Magellan, prompted the Viceroyalty of Peru to organize a large-scale reconnaissance mission. Command was given to Antonio de Vea, an experienced naval officer, who assembled a force of 256 men—an extraordinary commitment of manpower for a voyage into such forbidding waters. The expedition's fleet reflected the hybrid nature of the undertaking: one ocean-going ship capable of open-water navigation, two long boats suited to coastal work, and nine dalcas, traditional plank canoes built and piloted by indigenous Chono people, whose expertise in navigating the narrow, storm-lashed channels proved indispensable. This combination of European naval technology and native maritime knowledge allowed the expedition to penetrate further into the fjords than any previous Spanish effort, making it the largest and most thorough Patagonian expedition attempted up to that time.
Did You Know?
The Antonio de Vea expedition relied on nine dalcas—traditional sewn-plank canoes built by the indigenous Chono people—whose builders and pilots were essential to navigating channels that Spanish ships alone could never have safely explored. The Evangelistas Islets, where the sixteen men perished in 1676, were considered so dangerous that a lighthouse was not built there until 1896, more than two centuries later.
Tragedy at the Evangelistas Islets
Among the officers entrusted with a portion of the expedition's mission was Pascual de Iriarte, whose detachment was tasked with exploring the western approaches to the Strait of Magellan, a stretch of ocean notorious for sudden squalls, towering swells, and jagged rock formations. The Evangelistas Islets, a small cluster of barren islets marking the strait's Pacific entrance, presented one of the most dangerous navigational hazards in the entire region. On February 17, 1676, disaster struck: sixteen men under Iriarte's command were lost at the islets, likely victims of the violent seas and treacherous currents that had claimed sailors for generations before them. Contemporary accounts of the era rarely preserved the individual names or precise circumstances of such losses, and the surviving records of the Vea expedition offer little more than the bare fact of the tragedy. Nevertheless, the loss represented a substantial toll for a single incident within the broader campaign, a stark reminder that the expedition's scientific and strategic achievements came at genuine human cost. The Evangelistas Islets themselves, later marked by a lighthouse in the twentieth century, would continue to be regarded by mariners as one of the most perilous points along the Chilean coast for centuries after Iriarte's men perished there.
Legacy: Knowledge Gained, Interest Lost
Despite the losses suffered along the way, the Antonio de Vea expedition succeeded in its central objective: it found no evidence of English settlements or bases anywhere in the Patagonian channels, easing the anxieties that had prompted the costly mission in the first place. Beyond this reassurance, the expedition produced a substantial body of new geographic and hydrographic knowledge about western Patagonia, including improved charts of the channels, islands, and passages that had previously existed only in vague or speculative form within Spanish records. Pilots and officers documented currents, landmarks, and indigenous settlements, creating a body of information that would prove valuable to later generations of navigators. Yet paradoxically, this newfound knowledge did not translate into sustained Spanish engagement with the region. Once the immediate fear of foreign rivals had been put to rest, colonial authorities saw little further incentive to invest in the resource-poor, difficult terrain of Patagonia. Spanish interest in the area consequently waned for decades, and it was not until the 1740s—more than sixty years later—that renewed concerns about foreign incursion, this time driven by British and other European activity in the South Atlantic, prompted the crown to look southward again. The Vea expedition thus stands as a striking example of exploration driven purely by strategic anxiety, one whose hard-won knowledge sat largely unused until changing geopolitical circumstances revived Spanish attention to the remote fjords of the far south.
