Why might some of his own nation have given Equiano some ease during the Middle Passage?

From the text:

In a little time after, amongst the poor chained men, I found some of my own nation, which in a small degree gave ease to my mind. I inquired of these what was to be done with us; they gave me to understand we were to be carried to these white people's country to work for them. I then was a little revived, and thought, if it were no worse than working, my situation was not so desperate: but still I feared I should be put to death, the white people looked and acted, as I thought, in so savage a manner; for I had never seen among any people such instances of brutal cruelty; and this not only shewn towards us blacks, but also to some of the whites themselves.

EFAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
