How often did you hit them with consecutive bombardments?
On normal artillery settings, if hit hard in the open it is possible to cause retreat or even abandonment, I think damage may be required first for the later.
Can surprise you though Remember hitting one tank with a good wallop of artillery over a couple of turns & it still returned fire & took out my tank with a low to hit chance. Heavily pinned it could only get off one shot with its main armament which just happened to hit.
I realise what you are saying a big shell could flip a tank but how often did it land close enough to actualy do so.
While artillery was a major killer I would be intrestead to know how many rounds were fired per kill.
Do agree but we have had this debate so many times a big shell landing close to armor can have a devastating effect.
