how has the encounter with covey changed douglass?

This battle with Mr. Covey was the turning-point in my career as a slave. It rekindled the few expiring embers of freedom, and revived within me a sense of my own manhood. It recalled the departed self-confidence, and inspired me again with a determination to be free. The gratification afforded by the triumph was a full compensation for whatever else might follow, even death itself. He only can understand the deep satisfaction which I experienced, who has himself repelled by force the bloody arm of slavery. I felt as I never felt before. It was a glorious resurrection, from the tomb of slavery, to the heaven of freedom. My long-crushed spirit rose, cowardice departed, bold defiance took its place; and I now resolved that, however long I might remain a slave in form, the day had passed forever when I could be a slave in fact. I did not hesitate to let it be known of me, that the white man who expected to succeed in whipping, must also succeed in killing me.

From this time I was never again what might be called fairly whipped, though I remained a slave four years afterwards. I had several fights, but was never whipped.

Douglass gained self-respect, a new desire for freedom, a revival of his sense of manhood, and renewed self-confidence. He felt good about himself, satisfied with what he had done, and happy he'd done it......... even if it meant he'd be killed for it. In essence, he felt he'd been reborn.
