Nash's account includes elements of both poignant triumph and profound tragedy. Keeping in focus both the internal life of the black community and race relations in Philadelphia generally, he portrays first the remarkable vibrancy of black institution-building, ordinary life, and relatively amicable race relations, and then rising racial antagonism. The promise of a racially harmonious society that took form in the postrevolutionary era, involving the integration into the white republic of African people brutalized under slavery, was ultimately unfulfilled. Such hopes collapsed amid racial conflict and intensifying racial discrimination by the 1820s. This failure of the great and much-watched "Philadelphia experiment" prefigured the course of race relations in America in our own century, an enduringly tragic part of this country's past.

Nash tells of revolutionary fervor arousing a struggle for freedom that spiraled into the largest slave rebellion in American history, as blacks fled servitude to fight for the British, who promised freedom in exchange for military service. The Revolutionary Army never matched the British offer, and most histories of the period have ignored this remarkable story. The conventional wisdom says that abolition was impossible in the fragile new republic. Nash, however, argues that an unusual convergence of factors immediately after the war created a unique opportunity to dismantle slavery. The founding fathers' failure to commit to freedom led to the waning of abolitionism just as it had reached its peak. In the opening decades of the nineteenth century, as Nash demonstrates, their decision enabled the ideology of white supremacy to take root, and with it the beginnings of an irreparable national fissure. The moral failure of the Revolution was paid for in the 1860s with the lives of the 600,000 Americans killed in the Civil War.

The Forgotten Fifth is a powerful story of the nation's multiple, and painful, paths to freedom.

During the Revolution, Hull served Kosciuszko as an orderly, and the two became fast friends. Kosciuszko's abhorrence of bondage shaped his thinking about the oppression in his own land. When Kosciuszko returned to America in the 1790s, bearing the wounds of his own failed revolution, he and Jefferson forged an intense friendship based on their shared dreams for the global expansion of human freedom. They sealed their bond with a blood compact whereby Jefferson would liberate his slaves upon Kosciuszko's death. But Jefferson died without fulfilling the promise he had made to Kosciuszko--and to a fledgling nation founded on the principle of liberty and justice for all.

Author Nash writes: "The tough life, the deprivations - these are what made our parents and grandparents courageous and resilient. They had to fight for everything. They learned not to wilt under pressure, nor take anything for granted. They treated hardship as just a normal phase of life, a stepping stone to a brighter future."
