Canada and Denmark have a territorial dispute over Hans Island between Ellesmere Island and Greenland in the arctic. Starting in 1984, each country has sent expeditions which have placed their own national welcome notes, put up their own flag, and left accompanying bottles of alcohol as tokens of hospitality, (Denmark leaves Schnapps and Canada leaves Rye Whisky). Some people have dubbed this the "Whisky War".
All the articles I've come across suggest that has cycled several times with each country replacing the other country's sign, flag, and alcohol with their own but I haven't seen any indication of how often this happens. So does anyone know how much booze has changed hands over the course of the "war"?
