One of the strangest spectacles that man has documented is that of Phantom army. History records many instances of whole battalions of soldiers that simply appeared unexpectedly from nowhere to the amazement of witnesses, or floating cities that hover above water for hours at a time, cities that are so real you can see children and dogs playing in the street.Witness reports suggest that these phenomena appear to have a reality of their own, so what are they? In the past, this mysterious phenomena has been attributed to everything from the light of God to rips in the space-time continuum. Many thought them to be a supernatural event that forewarned of trouble ahead, while those of a more scientific bent have suggested they might simply be an example of mass hysteria or a trick of the light. It’s worth looking to see if there is a rational explanation for these supernatural events, because whether they can be explained or not, they are fantastic events worthy of investigation.Reports of phantom armies that have marched through countries have been recorded from as early as the seventeenth century, so this is not a modern day puzzle, it is one that has been witnessed many times.Scotland has a particularly well-documented history of phantom armies dating back to at least 1719. In January of that year, the Laird of Kingswells, Alexander Jaffray, and his riding companion both reported witnessing an army of some 7,000 soldiers west of Aberdeen. It was early in the morning, and a clear sunny day. What he saw was so real that he could make out the battalions colours, see the drums carried by the drummers and clearly identify the commanding officer, who was riding a white horse. The two men watched the army for two hours until it eventually disappeared behind a hill.The same army, led by the same commander was sighted in October of the same year. Then it was said that smoke could clearly be seen from the muskets they had fired but no sound was heard to indicate shots had been fired.In 1774, another phantom army appeared, seemingly floating above a mountain in Scotland, it was witnessed by a man named D. Stricket - Stricket had witnessed a lone phantom horseman the previous year in the same area. Like the 1719 sighting, the apparition lasted for a couple of hours until again, the army disappeared behind a hill.
