General Eisenhower and his chiefs in and outside Southwick House and the same 1944 plywood wall map today

In spring 2019, as a preliminary to observing the 75th anniversary of the end of World War II in 2020, a major work by the author will be released by Lyons Press/Rowman & Littlefield Publishers. Each of 22-chapters will examine overlooked aspects of the war. The 87,000-word book, with scores of rarely seen photos, results from decades of investigation and includes author photos comparing the appearance of the same locales from then to now. Additional excerpts will be periodically added.

Order your pre-sale copy now by going to Go to “books” and enter “The Hidden Places of World War II.” Amazon guarantees the lowest price and free shipping. Release date March 1, 2019.

Coming to these pages in 2018 will be dramatic then and now photos and a chapter excerpt from THE USAAF IN EUROPE, and a return three quarters of a century later to the remains of the same bases from where the “Mighty Eighth,” the Eighth Air Force launched thousands of attacks on Nazi Germany. Hint: much more remains than previously thought.


Shortly after a 415am weather briefing on June 4, General Eisenhower stepped-out for another smoke under the portico with the eight Doric columns of the immense 1841 three-story mansion near Portsmouth on England’s southeast coast. Into the first of up to four daily packs of Camels and fifteen cups of coffee, before dawn he and his subordinate commanders had already completed the first of two daily weather briefings with British meteorologist, Group Captain J. M. Stagg. Within the elegant interior, Stagg and his staff had just recommended a delay to the start of Operation Overlord, the liberation of the European continent from Nazi oppression. Ike had immediate major decisions to make.

Throughout the mansion’s spacious gardens were scattered numerous half-cylindered corrugated steel structures named after their inventor, Peter Nissen. Tents of various sizes and temporary housing extended from the surrounding woods almost to the mansion’s entry. For a brief time the ancestral home of the Thistlewaite family, Operation Overlord’s pre-assault naval communication center, would be the most important place on earth.

From where the stately home resided in the low hills above Portsmouth Harbor, Ike could almost see the water and part of the vast armada containing every type of naval vessel afloat. In addition to Portsmouth, eleven other British ports were equally laden with so many ships that it was almost possible to walk with dry feet from one vessel to the other, so closely were they moored. The supreme commander of history’s mightiest invasion force knew that every man from general and admiral to mechanic and rifleman, all 156,000 of them and millions more behind, awaited his command to instantly move from camps to landing vessels, or from the ships to the beaches. But it wouldn’t come that day and it wouldn’t come the next.

The first met report that June 4 – the second weather update would be at 645pm – painted a discouraging picture of high winds, low clouds, and reduced visibility predicted for June 5, the date of the invasion. Any one of the expected weather disturbances would hinder accurate naval gunfire and make certain the swamping of LCVP landing craft – the Higgins Boats – at the moment of dropping their bow ramps on the beach, if they even made it that far. Without fair visibility, erroneously dropping 300 paratroopers from the 101st Airborne Pathfinder teams, could fatally divert the 23,000 jumpers in the 82nd and 101st Airborne Divisions to follow. Any expectation of air cover over the beaches on June 5, Ike had been bluntly told, would be “impossible.” The ceiling would be under 1,000 feet. Yet, on June 4 major elements of the naval forces were already at sea, and, as Churchill would later write, “the movement was as impossible to stop as an avalanche.”

…As Eisenhower asked around the room for opinions, General Bernard Montgomery told Ike of his keenness to go, but none of the others were as hopeful. Each had a reasoned objection to explain why his part of the invasion force faced operational hurdles if not defeat. On that June 4, 1944 pre-dawn, weather made the decision: the invasion planned for June 5 stood-down as a no go. While a disappointment, it was not yet a setback. At least two, perhaps three days remained within the window of ideal low tide and bright lunar conditions needed to launch the invasion. But if the elements continued sour, the next time the moon and tides aligned wouldn’t come until June 19.

Waiting another two weeks came with the potential of defeat at the water’s edge. Keeping men already at sea or fenced-in at temporary camps another fortnight risked discovery and a loss of the vital edge needed for soldiers approaching sudden combat. Fresh troops rotating into the camps expected to be vacated by the invading soldiers would have nowhere to go. Miles of pre-positioned equipment on roads and at supply depots throughout England would need to be re-situated, presenting a logistical muddle on the narrow roads.

Some of the 6,939 vessels of all types, including 59 convoys stretching over 100 miles, would need re-fueling or re-positioning. By then, German spies or overhead recommaissance might have concluded from the evidence of masses of troops at scores or camps, and lurking ships in all the harbors, that the invasion wouldn’t happen at the Pas de Calais as expected. Maybe, the German high command could have concluded, maybe the invasion would begin at an obscure location not as well fortified. Maybe it would begin in Normandy.

(NEXT – Buffeted by coils of lashing wind and rain – Ike returns to Southwick House in the pre-dawn hours of June 5 to make the decision of the century.)

About Jerome O'Connor

Jerome M. O’Connor, a Chicago area journalist, historian and college educator, produces and lectures about the little-known, overlooked, or under-reported people, places and great events of modern history. To qualify, all locations must exist and are accessible. Deeply researched and dynamically presented multi-media programs result in numerous return invitations. Currently available are personally conducted tours to view and enter facilities depicted in his Chicago Tribune features, ARSENAL OF DEMOCRACY and MOTOR ROW MEMORIES. Updated for 2018 is the photographic result of a return visit to Bletchley Park in England, where 12,000 code-breakers revealed the 'secret of the century,' the breaking of the Nazi Enigma cypher machine. O'Connor was the first journalist to reveal its existence in a widely viewed 1997 cover feature in Naval History magazine and in British Heritage magazine in 1998. In an appearance at the U.S. Naval Academy, O'Connor was awarded "Author of the Year" by the U.S. Naval Institute. His much awaited first book entering the overlooked locales essential to the victory in WW II will be published in early 2019 by Lyons Press, an imprint of Rowman and Littlefield Publishing.
