For a history of the V1 & V2 developement and campaign - plus the intelligence war against them led by Dr. R.V. Jones - try to find a copy of "The Mare's Nest" by David Irving.
If you're ever training in Wichita, Kansas, don't miss the Kansas Cosmosphere in Hutchinson only about an hour away. It has both a V1 and a V2 (A4) on display and doesn't pull the punches about Camp Dora. It also has some incredible US & Soviet space hardware as well.
