Good stuff!
Mind you, I'm an amateur historian, so none of what Dan Snow's written comes as any surprise.
I deliberately didn't do history at school because I knew we were going to get all the same old drivel. One of my school mates waxed lyrical about HMS Dreadnought after one class - I completely threw him when I informed him she was clapped out and obsolescent by 1914! You should have seen his face - talk about a mental short circuit!!
