Abstract: Letter from the Viceroy of New Spain to King Philip II, dated October 1576, relaying concerns about the Philippines and the galleon trade. He notes the heavy costs of maintaining communication across the Pacific, the dangers of storms and shipwrecks, and the shortage of reliable sailors and pilots. The Viceroy emphasizes the importance of the Manila route for imperial strategy, urges caution in expanding further expeditions without sufficient resources, and calls for stronger royal support to sustain the fragile transoceanic link.
