What makes "Incidents" a slave narrative?

There seems to be a never ending need of the black writer to ingrave the existence of "self" on the world. This is probably due to the fact that the world has denied it historically. This seems to give the writing "intensity and focus." The commonality of American slavery is an experience that can teach us much when "treated narratively." "The Cambridge Companion to the African American Novel" says it is the only original form of American writing, and the slave narrative 'belongs' to African American novelists as no other literary form does. Jacobs' "Incidents" has the distinction of being the first slave narrative written/published by an African American woman. Up until her narrative, most of them were written by men. Men narratives basically stressed the bodily pain and physical fortitude of the slave. Vivdly described details of whippings and other tortures that destroyed an individual's manhood was its focus. To regain his masucalinity, the slave had to take back control of the master physically. This meant the slave had to physically fight the master. Consequently, he then had to flee to the North. The journey was filled with more injustices as well as narrow escapes before he victoriously made it to freedom. Jacobs' story is a new type of slave narrative given from the female slave's perspective. It begins with the autobiographical account of her life. It also includeds the endorsement by a white friend saying the work was authentic. She informs us in the Preface that she has changed the names to protect those innocent, and not so innocent.
