Across the land, congregations sent them off with food and with prayer. In the middle of the night, entire blocks of Harlem came out to wish them well. With the few dollars they scrimped from their labor, some bought tickets and boarded buses, even if they couldn’t always sit where they wanted to sit. Those with less money hitchhiked or walked. They were seamstresses and steelworkers, students and teachers, maids and Pullman porters. They shared simple meals and bunked together on floors. And then, on a hot summer day, they assembled here, in our nation’s capital, under the shadow of the Great Emancipator — to offer testimony of injustice, to petition their government for redress, and to awaken America’s long-slumbering conscience.
