From Past Imperfect:
It is noon on a humid Saturday in the fall of 1861, and a missionary by the name of Francesco Borghero has been summoned to a parade ground in Abomey, the capital of the small West African state of Dahomey. He is seated on one side of a huge, open square right in the center of the town–Dahomey is renowned as a “Black Sparta,” a fiercely militaristic society bent on conquest, whose soldiers strike fear into their enemies all along what is still known as the Slave Coast. The maneuvers begin in the face of a looming downpour, but King Glele is eager to show off the finest unit in his army to his European guest.
As Father Borghero fans himself, 3,000 heavily armed soldiers march into the square and begin a mock assault on a series of defenses designed to represent an enemy capital. The Dahomean troops are a fearsome sight, barefoot and bristling with clubs and knives. A few, known as Reapers, are armed with gleaming three-foot-long straight razors, each wielded two-handed and capable, the priest is told, of slicing a man clean in two.
