The historian Ira Berlin called this forced migration of slaves the "Second Middle Passage", because it reproduced many of the same horrors as the Middle Passage (the name given to the transportation of slaves from Africa to North America).
历史学家伊拉·柏林（英语：Ira Berlin） 把这种强迫移民称之为“第二条中间通道”，因为它再现了中间通道（英语：Middle Passage）（即将奴隶从非洲运往北美的路線）的许多残忍場面。
