Some events in wars keep being repeated with nothing learnt or changed. The ones I am thinking of are:
1. How many times did the germans have to invade through the Ardenne before the allies realised it was possible.
2. The bombing of Stalingrad, Monte Cassino Monastery and Caen after D Day showed that all that was achieved was to give excellent cover for streetfighting defenders and to block streets to vehicles. They still continued doing it.
Any additions welcome.
