Welcome to the “OPERATION IVY BELLS” Blog Tour! @RGWilliscroft @4WillsPub

RG Williscroft



I am Robert G. Williscroft, and this is an updated version of my bestselling, semi-autobiographical Cold War Novel. Operation Ivy Bells is a first-person account of the nuclear submarine USS Halibut and a team of saturation divers fearlessly facing death on the bottom of the Sea of Okhotsk while tapping Soviet underwater communication cables and retrieving missile parts from the seafloor, gathering intel that tipped the scales to win the Cold War. This story is reality-based—I led a team that accomplished much of what is depicted in this book.

Is Mac McDowell my alter ego? Yes, some would say, but in all honesty I would have to decline the honor. I was a competent and capable sub and diving officer, but Mac is smarter, more capable, and better than I was. I would welcome your visiting my website so you can get to know me better, and then compare the real me with Mac. Let me know what you think.

A warm thank you to my host for sharing this blog.

This book is available on Amazon.

Recognition for Operation Ivy Bells

This is what Navy Captain Don Walsh, first skipper of the Bathyscaph Trieste, had to say about Operation Ivy Bells when he read it:

Over the past few decades action-adventure stories about submarines and diving have become a popular genre. Tom Clancy and Clive Cussler come to mind as exemplars. But Robert Williscroft really raises the bar with this book. Not only is he an outstanding writer but he is also a ‘doer,’ having participated in the events described in Operation Ivy Bells.

Excerpt from Operation Ivy Bells

My first impression was a flashing shadow through one of the light beams, a flicker just below my threshold of awareness—something big and fast.

“What the fuck was that?” Harry squeaked, his voice distorted by helium and electronic descrambling.

“Green Diver, report!” That was the Master Chief.

01-Humbolt Squid-caption
“Jeezus…” Harry dropped down three feet and grabbed my left fin. I felt him trying to pull me toward him, toward the hatch. “Mac…the hatch!” Harry’s desperation came right through his squeak. Then he jerked and let go. “Kee…rist!”

“Red Diver…what’s going on down there?” That was Franklin.

Off to my right, a green phosphorescent shape flicked into and out of existence. A pink one materialized to my left. Suddenly, from right in front of me, something bright blue hit my faceplate with the force of a sledgehammer.

Everything went black. I don’t mean I passed out…everything went black, literally. I reached up and discovered a really large thing covering my entire helmet. It was smooth and spongy, and it was undulating. I heard a scraping, grinding noise against my faceplate. Something wrapped itself around my left arm, jerking my hand away from the pulsing mass. I pulled my arm back and felt a rush of cold water enter my suit at the wrist. A tear…whatever it was had torn a goddamn hole in my suit! What the hell can tear a hole through compressed, nylon-reinforced neoprene? That shit’ll stop a knife!

  1. It’s nice to *meet* you, Robert! Your book sounds so interesting. I love that it’s reality-based. Stefan, thank you for introducing us to Robert during his blog tour!

  2. Hi, Robert! Sorry I missed this post on the originally scheduled blog tour
    date, so I hope you still get this message. I just finished reading your
    excerpt from your Sunday blog post, and I have a question. Sunday’s
    excerpt is an exciting underwater hand-to-hand combat scene. Mac is
    fighting a “bad guy” diver, and ends up getting stabbed in his left bicep.
    His sleeve fills with icy-cold water through the knife-cut in his suit. Is this
    an inconsistency with the above excerpt where Mac says his suit will
    stop a knife, or is Mac wearing a different kind of suit in the combat
    scene? I look forward to reading your book, and I hope to see it on the
    big screen someday, too!

  3. In the scene from the excerpt, Mac is wearing a Poseidon Unisuit–The
    first practical drysuit. It was made of 3/8 in neoprene with black nylon on
    the inside and bright orange nylon on the outside. It is strong, but
    nothing like the compressed neoprene from which the hot water suits
    were made. Should a Unisuit sleeve (or anywhere else on the Unisuit) be
    cut through, water will flood the suit, eliminating any insulating
    characteristics it has. Mac’s su8t was cut through in the arm, so only his
    arm flooded, so long as he kept the cut lower than the rest of his suit.
    Because he was in an underewater knife fight, Mac did not pay particular
    attention to the cut orientation. onsequently, his suit flooded
    completely. This resulted in onset of hypothermia and an inability to
    maintain his depth because of the weight of thre water in the suit. Mac
    used a hot water suit during his thousand ft dive in Chapter one. As
    noted, the material of these suits was nearly impervious to knife cuts.
