Starting now would be good before the ground freezes over, get your self a rotor tiller. If you don’t own one there should be buisness that rent them by the day. First start by raking all top stones and get rid of if you don’t need them, clear the land of all unwanted objects and till the ground several times if need be!
While you are tilling pay attention to the kind of soil it is, I know I asked clarification and your answer was you thought it was clay so I will answer to that. If by chance it is other my answer can be ignored, reason is if the soil is normal and dark or black soil nothing should have to be added. I say this because you mention it had not been used for years, this means it is rich in minerals and nutrients enough for next year!
The ground may just be compact enough and hard especially after a long dry spell, if so the rain will not penetrate but run off. Let’s hope that it is not clay the procedure for working a garden or preparation is not easy. Since you are just ... more.
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.
