"e;The Divide"e; by historian Lucas Trent is a gritty, boots-on-the-ground account of the construction of the Panama Canal, framing it not just as an engineering triumph, but as a human tragedy and a geopolitical weapon. Trent moves the focus away from the politicians in Washington to the muddy hell of the Culebra Cut. The book details the catastrophic failure of the initial French attempt under Ferdinand de Lesseps, defeated by geography and yellow fever. Trent then explores how the Americans succeeded through the draconian sanitation measures of Dr. William Gorgas, who treated the mosquito as a military enemy. Crucially, Trent exposes the rigid apartheid system instituted in the Canal Zone, where workers were paid in "e;gold"e; (white Americans) or "e;silver"e; (West Indians), determining not just their wages but their housing, food, and medical care. Thousands of "e;silver"e; workers died in landslides and dynamite accidents, their bodies often unnamed. "e;The Divide"e; argues that the Canal was the first assertion of American global dominance, built on a foundation of scientific brilliance and racial exploitation.
