I recalled most from Neillands' Dieppe book. I don't know what people think of him but in 2005 I put down these points: Some bombing took place beforehand but this only warned the Germans that something might happen. Once the Hurricanes (?) Had attacked the defensive positions there was no actual protection from the sky. The ships giving naval artillery protection were too lightly armed and could not put out the bunkers and could not help the troops with their fire power. The planning was not good in case something went wrong. The only time the operation could be cancelled was 3 am, and after that it was go-go-go. Most losses took place during retreat. Neillands thinks Mountbatten was not qualified for the job. After realizing he had not enough protection for the troops he should have cancelled it or demanded more. About those tanks...29 got ashore of which 15 got onto the promenade. They could not get past the anti-tank obstacles and by then the engineers who should have taken care of these, most of them had been killed.
