The Ghosts of the Lost Mines
    The story of Robert’s experience from the previous chapter describing a network of underground bases and tunnels in the town of Brewster, New York, intrigued me enough to do more research on the subject. Despite my efforts at the time, however, I couldn’t find any data pertaining to any type of underground paranormal activity or locations of old mines. It wasn’t until March 1983 after the UFO sightings in the Hudson Valley that all types of paranormal reports started to be brought to my attention; many were from that particular area. At the time I was already occupied with investigating the hundreds of UFO sightings that had recently taken place so I didn’t think too much more about underground tunnels and mines until the summer of 1983 when two letters appeared in the editorial section of the New York Daily News .
    Mystery Tunnels
    The letters were from concerned residents in the towns of Brewster and Southeast who claimed the U.S. government was doing little or nothing about the recent rash of UFO sightings. One letter, from a Southeast resident, claimed that he lived near the old abandoned mines and on numerous occasions he saw military vehicles heading down the narrow dirt paths that lead to the entrances. One letter writer claimed he also observed large cargo helicopters of the Chinook class landing somewhere in the hills behind the mines. Needless to say, this caught my interest but the name of the person who wrote the story was not published and the editor at the paper told me it was signed “Anonymous.” Several days later I had a water leak in my study; the files that contained most of my recent work on the mysterious tunnels were severely damaged, but I was able to save one of the editorial letters dated July 1983.
    An Interesting Letter
    Why are people seeing all these UFOs, all of a sudden in the Hudson River Valley area? The answer is simple: there seems to be some kind of underground activity in the Brewster area, in the old abandoned iron ore mines. Some years ago the Government went out of its way to purchase the land that the mines are located on and people who live in the area including myself have seen military vehicles entering the dirt roads and they never come out. Also, we have seen helicopters landing in the hills close to the mine entrances. These areas have quite a few sightings of UFOs and people who live close to the mines have reported strange sounds and unusual lights as well. I feel that the Government has established an underground base in which some type of experimental aircraft is being kept. There is also a possibility that the mines are being used by our government and an alien intelligence to hide some type of operation in the area.

    If this letter printed in the Daily News was not enough to get my interest, three years later (1987), just after Night Siege ’s first publication, I received a call from a friend who is a CIA operative living in the southwestern United States who read my book. Part of my past military background was dealing with the Intelligence community, and I still had limited contact with individuals who are working not only for the CIA but also military intelligence. This person told me he came across a number of documents that were actually supply requests for an underground operation in the Brewster area. The documents said that the operation was located in an old iron ore mine near that town, but it failed to mention which mine and its exact location. My informant also told me that according to what he found out, the underground base was a lab that was being jointly used by a special operations unit. The underground lab’s purpose was unknown, but he told me he saw equipment lists that might be used in
