Battle Of Cannae, August 2nd, 216 Bc [PDF ebook] 

Tactics should have sought to guard against the surprises of the Carthaginian device. Initially, leaving aside the pride of the Equites citizens, the cavalry would have been balanced on both flanks, preventing the elite from facing a 1:3 ratio (1, 600 versus 5, 000); and infantry would not have been all concentrated in the center, not only after the initial success, but throughout the battle the penetration shoulders – right and left wings – would have been strengthened. In practice it will employ a Cuneus – the staggered over the center or convex but with flanks on Jomini s discontinuous lines.
