Let's blast some Myths by the numbers by the way, that will be easier and quicker. I'd like to recall before bedtime that German KIA during the Campaign of France and Low Countries, roughly one month, amount to 3,5 times the number of the African Campaign, which lasted 2 years and half - keeping in mind that African Campaign KIA losses are still lower than the "comparatively quick" Polish Campaign... So much about "long tough campaigns" I'd say, and our Polish friends will probably share that view... It's not because you do not resist a whole year that you don't give a fight
Another comparison? French Campaign German KIA losses are roughly equal to those of the Italian fightings from Husky (July 43) to November 1944... Well actually, if I take Feldgrau.com's numbers as a reference, the French and low countries campaign was the fourth most murderous in terms of German KIA after the Eastern Front, the Western post-D-Day Front and the Italian Front - and when it comes to a duration/KIA ratio, it may be (by not that much) the worst one, even before the gigantic 1,419,728 KIA, 47 months-long and 3000km-wide Eastern Front...
You would obviously expect Germany to not lose many men in the Mediterrean because Germany had, at the most, 9 divisions in Africa as opposed to the 120-140 it brought forth against France. Also, Germany lost 4 million on the Eastern front not 1.4 million. And, of course, using a duration:KIA ratio is a great way to reward countries that fight briefly and then surrender. Of course, the casualty per day calculation is more than 2:1 in favor of the Eastern Front. Given that you are the one talking about myths you should be wary of spouting uninformed nationalist propaganda.
