One I'd commend more for his storytelling than as a historian (though he's well researched) is "Lord Hardthrasher".
Comedy bits, maybe a bit too pro-British for non Brits and often sweary but he tells a stirring tale, and he picks his heroes and villains on both sides then lays it on thick. His series on the Bomber Mafia was great, as was his recent piece on RAF bomber command. His series on the Burma campaign was amazing. Big fans of Joe Stillwell might avoid that one, or have a stiff drink first.
