It was blockaded by ordinary people from the Argentine town of Gualeguaychú, who pitched tents on the asphalt and turned away the cars, trucks, and summer tourists that normally crossed into Uruguay. On the far bank, in Fray Bentos, Uruguayans watched their economy and their patience drain away. The two countries share a river, a language, and a tangled common history, yet a pulp mill nearly tore them apart. One president would later admit he had readied his military and sought American backing in case it came to war.
