“Traditore batteries, by hypothesis, fire only to the flank and rear. They are thus always placed, behind a corner; that protection is continued laterally for such a distance that a projectile from any likely direction will either meet the covering mass or pass clear of the gun muzzles.” —Encyclopaedia Britannica, 1922
