A quibble if we're trying to provide accurate information here. I toured Dieppe with a reputable Canadian guide last month and he indicated that almost all of the tanks did in fact make it off the beach but were stopped from advancing into the town by anti-tank barriers. The failure of the attached engineers to deal with these due to enormous casualties resulted in most of the tanks returning to the beach where over the course of the morning they did eventually throw tracks as they maneuvered. The nature of the cobble was well known and similar to many (most?) UK beaches. No sources, but worth digging into if you are interested. klambie Not to quibble, your quibble but the promenade is not the beach and as you aptly point out (but I will be more direct) the engineeres who were to blow the obstacles were all casualties, the tanks that reached the promenade (all 4 of them) returned to the beach and resolutely remained in their tanks to provide whatever cover fire they could until their ammo was depleted. they then wisely chose to remain in their tanks rather than add to the casuatly toll of those unprotected on the beach. as for the cobble they friggin' well should have known it was impassable to tanks before when they planned this fiasco. After a quick bit of digging, 27 tanks landed and probably 15 made it off the beach. Not the "almost all" I stated, but a substantial number. The count of 4 you mention (some say 3) is not accurate. The North Irish link below indicates only 5 failed to get off the beach due to the chert and attempts to describe the fate of all 30 tanks committed. The CMH paper summarizes 29 attempted to land, 2 drowned, 15 across the seawall (10 of which later returned to the beach where 1 was immobilized due to chert). Of those that didn't get off the beach, 4 had tracks broken by shellfire, 4 by chert and 3 likely by chert, though it is uncertain, 1 remained on the beach and was mobile throughout. http://www.cmp-cpm.forces.gc.ca/dhh-dhp/his/rep-rap/doc/cmhq/cmhq108.pdf para 2-7 http://northirishhorse.net/articles/Dieppe/16.html http://scholars.wlu.ca/cmh/vol4/iss1/6 Abstract only.
