Eddie celebrates some Welsh firsts: pioneering scientific achievements on land, at sea, in space, the universe and everything.

We know that Wales powered the world by exporting coal but did you know our lager quenched the thirst of the Empire and our tinplate kept food fresh for pioneers in the Wild West? Globalisation is nothing new. From Swansea's Cape Horners to Newtown's woollen sleeping bags that clad the Russian army, Wales has long been at the heart of international trade.

Eddie Butler discovers the story of Wales's involvement in wars throughout the ages - from the Roman invasion to the development of the atom bomb. Find out about Wales's remarkable contribution to battlefield medicine, why Spanish children ended up exiled in Bangor, and how Italians were treated when the Second World War broke out. And why is there a model of a French guillotine in Welshpool?
