From Florence Baker's unpublished diary of the expedition and her letters home, coupled with the account in Samuel Baker's journals and the diary of his nephew, Julian.
One of the most compelling books I ever read. This should be required reading for a wide range of high school and college history courses. It clearly shows the depravity of the African slave trade as late as the 1870’s (well after the end of the War Between the States) and describes in their own words the lengths to which a determined group of English went to stop the abuses. Highly recommended.
