Is The Bridge of Deaths really a culmination of two decades of research? Why are you so interested in WW II History?
Yes, at least a good eighteen years of research. I was so clueless when I began to dig around the plane crash that killed my grandfather in 1939 so I guess someone with a better historical background would have never taken that long.
I am embarrassed to admit that I had to look up almost every incident I came across even something as common knowledge as The Munich Pact.
I know I had to have studied it at some point in school or university but to be honest I know I did fail history at least once.
