The Fates of Various Nazi Warships:
Given the penchant for featuring even quite famous and obvious things under false names in comics, I always end up noticing when something or someone shows up under their own moniker, which is why I was very surprised when Royal Navy submarine captain Tom Niles, aka the Undersea Raider, is responsible for sinking several real Nazi warships in this 1940 comic. The casualties include the cruiser Admiral Scheer (sunk in 1945 in our world) and the battleships Bismarck (scuttled in 1941), and Scharnhorst (sunk in 1943). I had thought that the Admiral Graf Spee was another of these anachronistically early kills, but this depiction of it's scuttling off of Montevideo, Uruguay is broadly accurate, except that it happened in 1939. A wild time for naval combat. (Thrilling Comics 004, 1940)
The Fate of Rome:
Specifically, the fate of Rome during the Great Fire of 64 CE. There are a lot of theories about how and why the fire was started, but very few of them revolve around it accidentally being started by magician/adventurer the Ghost and his companions while attempting to escape Emperor Nero's soldiers with the help of an electric ray projector.
