Another reason why trench warfare was supplanted by Blitzkrieg is technological. Blitzkrieg didn't really come into its own until rapid, mobile platforms were technically possible in WW2. Note that the idea is to limit engagement along lines of combat. The longer the line or time of an engagement,as in WWI, the more casualties. Technology drives warfare to more limited engagement with the enemy. Trench warfare kills more than Blitzkrieg. Blitzkrieg by itself kills more than Blitzkrieg plus "smart bomb technology." (Of course this only applies to conventional battles, not to total war with weapons of mass destruction. I don't think I should have to qualify this, but I might as well put it here.) ------------------------------------------------------------------ To change your Lit-Ideas settings (subscribe/unsub, vacation on/off, digest on/off), visit www.andreas.com/faq-lit-ideas.html
