Though much smaller I’ve always found WWI much more difficult to study than WW2. It’s the pointlessness of the horrible slaughters engineered by incompetent buffoons like Haig. Years of masses of men charging machine guns in daylight. Hideously disgusting.
WWI was terribly bloody.
But give the “Great War” a try.
Both sides did everything they could to solve the problems of technology, trying all sorts of experiments, while trying to figure out how to make modern war at all, in matters of personnel, production, logistics.
Everything was changing at an enormous rate.
Nothing came easily, because clever ideas were all well and good, but would they scale?
Ww1 was silly stupid and dumb. A bunch of aristocratic nobles signing mutual admiration treaties of self protection to keep the nobility in power. It all backfired terribly. If Germany had won,,,well there might have not been a WW2. However, who the heck wants a super strong Germany?! Roosevelt kissed the rear end of evil Stalin and allowed the evil commies to take over Eastern Europe.
I listened to Dan Carlin’s 6 part Hardcore History podcast on WWI called Blueprint for Armageddon. I am a huge fan but have never been the same since listening to that. The two world wars wiped out the European bloodlines and have left nation of wusses as a result.
