Stages of the Spanish civil war

I’m a sucker for maps, so as to give you an idea of the progress of the war, I’ve created a map illustrating the nationalist gains in territory throughout the Spanish civil war. Not illustrated on this map are various islands (such as Ibiza), and Morocco, all controlled by the Nationalists. Furthermore it should be noted that Portugal was not exactly as neutral as it would seem from these maps—most of the German help to the Nationalists came in through Portugal. Having said that, here is the map.
