The status of Berwick upon Tweed, not that far from where I live, has always been a subject of controversy because although it lies naturally beyond the borders of the Tweed, and therefore geographically in Scotland, was, and is, the last possession of England in that region (similar to the position of Calais before 1558). The declaration which launched the Crimean War specifically mentioned the said town, for the avoidance of any doubt. The Treaty of Paris in 1856 which concluded the war failed to mention Berwick, which led to the erroneous conclusion that Berwick and Russia (later the USSR) were still at war. This is a nonsense of course, because as Berwick is legally an English town it is covered by the said treaty. However it gives the good burghers of Berwick something to boast about during the long, lonely nights in the pub.
