BBC - Nelson's Caribbean Hell Hole (2013)
Human bones found on an idyllic beach in Antigua trigger an investigation by naval historian Dr Sam Willis into one of the darkest chapters of Britain's imperial past. As archaeologists excavate a mass grave of British sailors, Willis explores Antigua's ruins and discovers how the sugar islands of the Caribbean were a kind of hell in the age of Nelson. Sun, sea, war, tropical diseases and poisoned rum.
