Off the rugged coast of Muckle Flugga, a remote island in the Shetlands, a bizarre encounter took place on 28 July 1918. The German submarine U108 was on a mission when its crew spotted something enormous and utterly unexpected - a giant marine saurian, estimated to be between 18 to 24 metres in length. This was no ordinary sea creature, and the U108's crew were left to ponder the reality of what they had seen.

The First World War was in full swing, and the seas around the British Isles were a hotbed of naval activity. On that fateful day, U108 was patrolling the waters when it came across the mysterious creature. The encounter was documented as a cryptozoological event, one that has sparked interest and debate among researchers to this day. The German submarine's log provides valuable insight into this unusual sighting, a testament to the strange and unexplained events that can occur in our world's oceans.
