The prize was a doorway between two oceans. In the nineteenth century, before the Panama Canal, the Strait of Magellan was one of the only ways to sail from the Atlantic to the Pacific without rounding the deadly waters of Cape Horn. Two young republics, Chile and Argentina, both claimed the cold lands at the bottom of South America, and for decades they fought over them not with armies but with letters, surveys, competing maps, and a strange contest for the loyalty of the Tehuelche people who actually lived there. The struggle would end at a negotiating table in 1881, but the years before were a slow, tense, and very human standoff.

Much of the dispute was waged on paper. Surveyors from both sides charted a land so poorly known that maps could barely agree on its features, and rival cartographers redrew the border again and again through the 1870s. The contest even named a glacier twice: a Chilean captain ch...

Chile had powerful reasons to settle. By 1879 it was entering the War of the Pacific against Peru and Bolivia, and it could not afford a second front in the south. A resolution would keep Argentina from joining that northern alliance. The breakthrough came with the Boundary Treat...

The 1881 treaty ended much of the quarrel, but not all of it. The two nations went on disputing the meaning of its words for more than a century, and the rivalry over the islands south of Tierra del Fuego eventually hardened into the Beagle conflict, which brought Chile and Argen...
