Recently I have founf this picture in internet [ http://www.humanosphere.org/wp-content/uploads/2013/08/map-where-brits-never-invaded.jpg ] which apparently show countries that were ever invaded by GB. I am from Poland and I don't ever recall hearing about British forces invading neither my country nor Lithuania. Is that map correct in that matter and if so then when that event have happened?
Probably Napoleon coalition, Poland (Grand duchy of Warsaw) was allied with him.
