What were US troops doing in Sumatra in 1832? And why was there a Korean War in 1844? This book puts US history in a whole new different light. Americans know about the Revolutionary War, the Civil War, the world wars, Korea, Vietnam, and Iraq/Afghanistan, but the many in-between conflicts have been erased from public memory. Many of the forgotten conflicts have a particular resonance now. The Texas-Mexico border conflict (1917) saw Hispanic farmers murdered as America prepared to invade south of the border—no Trump Wall then. The US kept 150 men as official POWs for 36 years after a conflict that ended in 1873—which one? This book is full of surprises, many of them colored by irony and often tragedy: the Barbary Wars (1801-3) were fought to end the North African slave trade. The Philippines War of 1899 caused the death of over 200,000 civilians. This companion volume to Britain's Forgotten Wars, this book puts US history in a whole new light.
