During the Napoleonic Wars at the beginning of the 1800s, when England was at war with France, there was a particularly vicious storm off the North East Coast. During this the Hartlepool fishermen could see a French vessel struggling against the heavy seas, and eventually sinking. Wreckage was washed ashore and clinging for dear life to a piece of this was the ship's pet monkey dressed in a soldier's uniform. The ignorant fishermen did not quite know what to make of it - after all they had never seen a monkey before and neither had they seen a Frenchman - so could this be one of their French enemies? It was decided to immediately hold a trial on the beach, and the conclusion that was reached was that the monkey was a French spy. It was promptly sentenced to death by hanging and this was duly carried out using the mast of a fishing boat as the gallows.
Not surprising in our times, a more modern spin has been put on this legend. It has been suggested that the distressed craft was not a French ship, but a spacecraft, and that the monkey washed ashore was actually an alien. The authorities are said to have taken the strange creature away, and instructed the locals to spread the story about the monkey as a diversion. The wreckage from the supposed alien craft which was washed onto the beach is said to have been removed by the aforementioned authorities and buried to the south of Seaton Carew. In recent times a nuclear power plant has been built here. It is said that this has been constructed over the site of the alien craft's remains to ensure that they are never found! I believe the originator of this tongue in cheek version of the legend was Ray Totty, who now lives at Seaton Carew.
