Hitler's long range cannon was not very successful. Only smaller versions worked, but were never really effective. Out of 183 shells fired over a little less than 2 months, only 44 hit urban Luxemburg, with 10 dead and 35 wounded.
Yes, Joe Kennedy Jr, was killed flying a explosive laden bomber to attack this project (V-3). They were to arm the explosives and bail out, while the plan would be guided in remotely. Unfortunately the bomber exploded soon after the armed the explosives before they got a chance to bail out.
No civilians were ever injured by the cannon or the exploding bomber, though there was significant damage to the village it crashed near. Had the bomber done its job, few civilians would have been killed that were not working on the project.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
