Battle of Trafalgar

HMS Victory Copper Bottom

Liz goes for a cruise on the River Tawe and picks up some tidbits:

Three facts from my trip: Swansea has the second biggest tide in the world; the battle of Trafalgar was won thanks to the copper-bottomed boats of the British Navy, the copper having been produced in Swansea; and the only known occasion when yellow fever was transmitted in the UK was when a number of infected mosquitoes travelled to Swansea from Cuba with a cargo of copper ore.

Liz, Swansea and the River Tawe are all in Wales. Have I posted anything about Yellow Fever before? More than I realized.
