I don't usually give 5 star ratings, but this History show absolutely deserves it. Being American, I don't really speak English, but I can generally keep up with Tony's concise commentary. His delivery is excellent.
Not having a map of the United Kingdom burned in my brain the way most people have of where they grew up, only interfered during the study of the English Civil War. An external map really helped there, but Tony added many details that I would not be able to get off of any map. He treated other topics similarly, but did not expect the listener to know where things were outside of the home islands. In other words, he gave us the geography that we needed for a complete picture.
Although I am not a student of it, I thought that his coverage of the Battle of Britain over several episodes was clear, well researched and while it pointed us in a direction it did not make any judgements for us.
I am partially hard of hearing, but I can hear Tony's voice almost all of the time. I actually keep some episodes on my smart phone to re-listen to when I have a long wait.
Well done sir, well done!
