I like the concept of the quiz, but you need to do a bit more research. "Blitzkrieg" is not the name of a battle or even a tactic - it's a catch-all term for how Germany fought against a lot of opponents. There were no Japanese or Americans at El Alamein, no Brits at Guadalcanal and rather a lot more people than just Americans and Germans at Monte Cassino. "D-Day" is understood by a lot of people to mean the Normandy landings in 1944, but it's not the name of that battle or even of the Operation behind it - every operation had a "D-Day" at its start. Keep on reading and learning, and keep up the good work making quizzes.
