"I would not ordinarily expect, in a book about the American Civil War, to see mentioned the eruption of Mount Dubbi in Eritrea, May-October 1861, the largest such documented on the continent of Africa. But then Jeremy Black is no ordinary historian, and his notion that the eruption may have affected American weather patterns in 1862 (wet spring, cold summer) is but one example of his wide-ranging command. The field of Civil War history is already well tilled, but this relatively short volume succeeds in broadening it." -Robert Erickson, The New Criterion
