Operation Sea Lion
The most infamous invasion that never was, Operation Sea Lion holds a special place in the annals of alternate history. Richard Cox’s book takes a 1974 wargame of it at Sandhurst and turns it into a Hackett-esque big picture tale. This can be described as a World War II version of The War That Never Was, taking simple wargame results and giving them a tiny fig leaf of “plot” via various vignettes.
Not surprisingly to anyone knowledgeable about alternate history, the wargame, despite deliberately going easy on the first wave (to have a substantive ground element at all) ends with the Royal Navy cutting the lines and the Germans defeated. It’s not Cox’s fault, but something with the outcome never in doubt is hard to make exciting for someone who knows the context.
That being said, this remains an amusing little historical alternate history footnote. It’s aimed at a popular audience who wouldn’t necessarily know the context, and is at least more literary than a rote after action report of the wargame itself would have been.
