In the first instance, only 33 landing craft were lost in the operation. I am struggling to find an exact number, but there were 9 Landing Ship Infantry, each with between 10 and 20 landing craft. Even at the lower number, 33 lost out of 90 isnt exactly most, and at a strategic level it was almost inconsequential.
Sorry, my mistake. By oversight and generalizing too much I used a false word,
most...instead it should rather be...
the Royal Navy lost much of its landing craft...or...
the Royal Navy losses were very high. The exact number is 28%, it's not meaning the most, but it is a high number in losses, or in casualties.
As for why the choice was Canadian troops, this was down to a number of reasons. In the first instance, the vast majority of the British troops that had been raised up until 1941 were deployed in North Africa, Burma, the Middle East and various other theatres. At this time, British troops were favoured as they had predominantly been formed around Territorial units, whose order of battle and organisation was well established. That is, they were better organised to fight. Canadian troops had a tremendous reputation, but they were considered to be less well trained and thus kept in the UK for more training. Therefore, they were probably the best trained units in the area of operations able to undertake such a mission. Furthermore, the Canadians actively relished the chance to engage and prove that they were capable of independent brigade level operations.
Yes, I agree. The Dieppe Raid began in optimism. The size of the Canadian Army in the UK continued its growth in manpower, but only some had seen true action, or combat, to be exact, the Canadians hadn't seen action since the Japanese victory in Hong Kong, late in 1941. Many of them were eager and had a desire to see combat - keen to tell their English girlfriends true stories from the war and being heroes of the front. Also, the Canadian commanders and the generals learned the Dieppe battle plan and accepted it - but nobody knew, it would come by a terrible cost, one of the darkest chapters in the Canadian military history.
While Dieppe was a tactical failure, it was an operational draw and strategic success. As you note, it provided the Allies with important information regarding German defenses. It further gave the British an opportunity to capture the 4 rotor enigma machine (if O'Keefe's research is to be believed). So I am sorry, it was not Malice that pushed the British to use Canadian troops, nor were the British seen as incompetent following the operation (rather, it was the Canadian Batallion level command that was seen as concerning).
I don't see how Dieppe was an operational draw? Any battle what's not happening is an operational draw, so this would had happened even without Dieppe, without wasting the resources and the human lives. The Dieppe Raid would come with a disastrous ending - it was clear from the very beginning, the planning was poor, the Allied assault was carried out almost in total blindness. The German garrison in the port town was 2 000 of men and they were heavily fortified and well armed. With a landing force of 6 000 men the Allied objective was to test the new tactics - the amphibious warfare and combined arms. The Royal Air Force should had drawn the Luftwaffe attention, while the landing force carried on its mission, to capture the city of Dieppe, destroy the nearby German airfield and German HQs, take German officers as POWs and blow up Dieppe radar station. After all this, the landing force should return to the beach, embark the ships and sail back to England. This doesn't sound realistic in my opinion, especially when the Allied radio broadcasts had previously informed about this forthcoming military operation in Dieppe sector. During their desperate moment in the Finnish Civil War the Red Guard soldiers stated -
But, it looked so easy on the map. The same comes in true with Operation Jubilee, a bold and ambitious plan backed by the courage of inexperienced rookies. The Dieppe Raid happened for two reasons, first the British desperately wanted the intelligence, they wanted to show their commitment for the Allied cause and improve their military skills and capabilities, secondly the Canadians were willing to carry out the operation. Without these Allied interests Dieppe wouldn't never happened. Yes, the British got the intelligence, so the operation came with this piece of information. But this information came in form,
do not do this in war, surely, there was other means and resources to determine this. Was this conclusion and information so major and great worth that it covered the casualties, nearly 4 000 of men and their suffering, I cannot answer, but I bet that the contemporaries, the injured party could reply clearly.
