On the afternoon of April 8, 1665, several fishermen doing their jobs near Barhöfft, which at the time belonged to Sweden, now modern-day Germany reported the sighting of a Battle between ships in the heavens. Shortly after the battle had concluded, people witnessed a dark, disk-shaped object overflying the area where the battle had taken place.
