Agreed. Verdun didn’t work, Battle of Verdun didn’t work… so I stopped writing and gave up on the quiz. Not accepting Germany for German Empire is also a bit too strict in my opinion… it made me wonder what you meant by “leader”.
I genuinely don't know how I succeed to have only 9/25 while having all the answers. For most of them, several answers can be used, and some type-ins need to be added.
Churchill absolutely did not fight in WW1. He infamously hid the disaster of Gallipoli by censoring the press and reports to Parliament so he wouldn't look bad, thereby killing 100s of 1,000s more people.
He did serve on the western front as an officer until 1916. You are correct that he did cover up Gallipoli. And due to the Gallipoli campaign failure He was demoted and resigned from his government position. He then went and fought until 1916
