Today’s Date: Reclaiming Bornholm

On this day in 1658, Danish rebels captured Commander Printzenskiöld of the Swedish army and won back the island of Bornholm for Frederik III.

It was not the first time the island had changed hands, and it wouldn’t be the last.

The Soviets were the last foreign power to hold it, eventually withdrawing in 1946 after liberating it from the Germans.
