A bit of background on the Island from 1951
"DENMARK HAS AN ISLAND IN THE SOVIET'S BACKYARD
From CHARLES CROOT
Reuter Correspondent in Bornholmn
THIS TINY, 150-square mile, medieval Danish island of Bornholm, where the telephone is still some
thing of a novelty, is the Baltic outpost of the Atlantic peace defence organisation.
IT is Denmark's eastern most island and, except for part of Northern Norway,
the most easterly point of the pact area.
Bornhalm's 50,000 inhabitants can hear, from time to time, the guns of the Soviet fleet exercising in the Baltic.
To Roenne, the island's main port, come, occasionally, Danish fishermen released
after detention by the Russian authorities in the Baltic on charges of fishing inside Soviet territorial waters. On the south-eastern coast, lies the wreck of a Soviet trawler which went aground
in bad weather over a year ago.
In Roenne and Nexone are ruins caused by a Soviet air attack, mounted in 1945 when the occupying German forces refused to surrender to the Russian liberating forces."
