Continuing with You Can't Tell the People The Cover Up of Britain's Roswell by Georgina Bruni.

...Ever since General Gordon Williams was featured in a British tabloid as having conversed with alien entities in Rendlesham Forest, researchers and journalists from all parts of the world have tried to track him down. No doubt I would have been one of those, so imagine my surprise when in the early part of my investigations I received an electronic mail from someone claiming to be General Williams. My first thought was that I was being hoaxed or set up to try to discredit me or lead me off the track. I was certainly not convinced he was who he claimed to be.

The electronic mail was short and to the point. Basically, he identified himself as the USAF wing commander of RAF Bentwaters and Woodbridge during the alleged UFO business and wanted to know what was new on the case. He signed himself GW. I did not reply to his request for some weeks because I wanted to do a little background research on General Williams. I began by checking the white pages, which are the American domestic telephone directories, but he was not listed. I requested an Air Force Freedom of Information biography on the general, which at least gave me the ammunition to question him. In the meantime, I discovered he was a regional president for the West Point Society and later I would learn that he was involved with the Council on Foreign Relations. Although retired from the USAF, he is still very much a high-profile figure who serves as a defence consultant to several major companies.

According to Larry Warren and Peter Robbins, when investigating the case for Left at East Gate they were told that General Williams was in California, but my mystery man was not based at that location.
