Unable to achieve sustained military success in the Civil War, the Confederacy tried a daring strategy in 1864--commando-style raids into northern states from Canada. Taking advantage of the undefended border, rebels hit targets along the Great Lakes, where growing antiwar sentiment was an election-year problem for the Lincoln administration.

Revisiting one of the forgotten chapters of the war, this is a deeply-researched history of the South's operations in Canada. One of the most significant raids is covered in detail for the first time: Virginia planter turned Confederate agent John Yates Beall's attempt to liberate 2,700 Confederate officers from a prison camp on Lake Erie.
