Hi drach, What is your opinion of Admiral Yamamoto? I've been reading about him lately and the most recent pieces seem to make him out as a nationalistic, war hungry lunatic who thought the Japanese could just march into Washington. I always thought of him as a solid professional officer with a touch of the Warp in how accurately he predicted the course of the war. Is there any chance we could get a Wednesday special about him?

The Directorate of Miscellaneous Weapons Development (RN) and the Ministry of Defence/Army agency MD1 (intially MIRc,) were parallel organizations, both of which were staffed with collections of mad scientists, garden shed inventors, young troublemakers, pyromaniacs and cat herders. MD1 developed the Limpet Mine, the Blacker Bombard spigot mortar, a remarkably wide range of mechanical detonating devices for engineers, saboteurs, and boobytrappers, and the PIAT. DMWD were the people who developed the Hedgehog forward-throwing anti-submarine weapon, the Squid anti-submarine mortar, and the first practical system for degaussing ships as a defense against magnetically-detonated mines. DMDW also developed the Holman Projector, which was, as for as I know, the only steam-powered anti-aircraft weapon ever used in naval warfare, and so-called "plastic armour," which were hollow steel panels filled with gravel and bitumen, intended to provide splinter protection to critical areas on merchant and fishing vessels taken into government service, as well as on lighter vessels such as landing craft produced without any armor.

American or "Yankee ingenuity" as one of my British coworkers called it, also helped the allies in WWI. Combat Engineering companies that rolled large rolls of chicken wire across the barbed wire that served as a barrier to entangle and slow the standard frontal infantry assault. AEF planners also implemented the 1st "rolling artillery barrages. Those two items helped keep the Germans pinned up in their shelters while American forces stormed the trenches faster than other allied forces up to that point, due to basically nullifying the effects of becoming entangled in the wire. Using those tactics successfully reduced the number of casualties and allowed the German lines to be pushed back with greater successes than any other previous tactics being used on the battlefield at that time.

[@colbeausabre8842]

One of my neighbors growing up had been the CO of an LCT during the great storm. She was blown ashore and had to wait for weeks to be salvaged. Due to fear of Luftwaffe attacks, no lights were to be shown at night and they were to lie low. Then, one night, it happened. Around dusk, first one ship, then another began firing, soon grounded vessels and Army AA batteries joined in. Artillery roared, small arms rattled and tracers sped into the night. Off shore, even the battleships and cruisers were giving their all. Flares and star shells illuminated a surreal scene. Convinced the Germans had broken through, and were headed to the beach, my neighbor sounded general quarters and rifles and submachine guns were issued to all hands not manning a gun. My neighbor strapped on his 45, determined to "take one with him." Then it occurred to someone to look at the calendar when making an entry into the log and yelled the news. That's how my neighbor and thousands of his brothers in arms celebrated July 4, 1944.

My father was in the Royal Engineers (being an engineer in civilian life before joining). He landed on the first day at D Day and after being initially deployed to remove beach obstacles worked on the assembly, construction and rescue of Mullberry B working with Sainsbury to secure the pontoons and to ready for the storm. He further went on to many adventures through and beyond the Rhine crossing. He would still say to me many years later that the Mullberry harbours made the D Day landings a possibility and not the disaster that the majority feared. The whole concept being bold, innovative and took the Germans entirely by surprise and he felt that the German high command did not realize how the allies could supply so many men and they did not respond fast enough as they determined that the level and logistics they faced would be so much a smaller problem. He also use to mention the laying of Pluto within weeks of the landing supplying fuel. Kind regards

[@lllordllloyd]

I think you can really see the truth of this in the German high command's continued obsession with port denial through 1944. Wrecking Cherbourg, leaving garrisons all over the French coast, swallowing Fortitude and the threat to Calais, dumping half their V2s on Antwerp...

The ETO Allied forces also tended to not talk much with their US Navy Sea Bee counterparts from the Pacific and Southwest Pacific theaters... the US Navy Sea Bees included in being a bit parochial. Many of the Pacific island landings were on long shelving beaches with rather large tidal ranges, and the USN solutions were very similar to the Spuds, Beetles, and Whales, but used the Rhino pontoons rather extensively. Some of the Pacific storms were also quite intense, if possibly a bit less chilly in temperature than the Channel "Summer" weather. Communications between Hawaii / California and the UK weren't what they might have been, and there appears to have been some reinventing of wheels. There was also a general shortage of trained engineers to go around, and experienced engineers had to be found and then help out the junior engineers... many of whom were like my great uncle - a watchmaker/jeweller who got commissioned as a 2nd lieutenant in the Army Corps of Engineers - quite proficient after training in setting up bridging and treadway equipment, but not trained at all in pump selection and operations on the scale required for the Mulberrys. Still, the guys muddled through, and were quite successful in the end.

I worked in the 1980's for one of the civil engineering contractors who had built some of the Phoenix caissons. Both during my interview & first day of work, I was informed with almost reverence ''This is a company that was involved with the building of the Mulberry Harbours''.... Even 40+ years on at that time, it was still a proud & highly important part of the company's history. I later found out there was a fulfilled request for some of the company's civilian site staff & tradesmen to travel with the caissons they had constructed, mainly to operate standby pumps & keep an eye on timber chocks & bracing that kept the seawater valves firmly closed. (not sure if that was just to the staging point within UK waters or whether they actually went across the Channel also)

As part of the program we also did a costal tour. One of the stopps was Arromanches and the remains of Mulberry B were clearly visible. This was truly a crazy project. And for me it puts into perspective the utter impossibility of operation "Seelöwe" succeding. Germany just didnt have anywhere near this level of logistics ready in 1940.

He was responsible for Phoenix sections that would be sunk off the UK shore, and re floated, towed to the Normandy beaches, and sunk again, he was tearing hus hair in frustration, His Navy day job was marine salvage, and getting sunken vessels re floated. He felt, correctly, that the planners had not correctly estimated the difficulty in getting the Phoenix sections re floated for towing. There was am enormous amount of suction to counter when re floating that the planners had not factored into their plans. Local response to his concerns took the form "You want to tell the _Royal Engineers_ they don't know what they are doing?" "In ytis case, eas, because they don't!" Once he got to talk directly to them. they looked at his calculations and concerns, and decided he had a point and plans needed to be changed/

In defiance of orthodox opinion they beached coasters (LST's) and unloaded them direct into Army lorries at low tide... during July the Americans here handled more than twice the tonnage which passed through the British Mulberry."

The crossing took over thirty hours - no very swift passage. We - that is, the squadron of some ten similar chunks of concrete - had the protection of no convoy of our own; we were much too slow for any convoy to stay with us. But by keeping in the main stream of invasion traffic bound for France, we had the benefit of the occasional presence in our vicinity of destroyers passing us accompanying faster groups, mainly troop carriers."

"We found that the waves at the American harbour were significantly larger than those at the British Mulberry - although both experienced waves larger than they were designed to withstand. This goes a long way to explain why the American harbour failed whilst the British one narrowly survived. We also found that a storm of the severity of the 1944 storm would only be expected to occur during the summer once in every 40 years. The Allies were clearly very unlucky to experience a storm this severe only a couple of weeks after D-Day." University of Oxford The storm that struck the Mulberry Harbours page

Dad volunteered to run the engine room on one of the breakwater ships. He said the holds were loaded with rock. When the Royal Coast Gauard signaled they were in position, the skipper called everyone to the bridge where he counted the skeleton crew and then threw a big knife switch the set off the scuttling charges. The crew then clambered onto the Royal Coast Gaurd Cutter and and dad went back to Portsmouth to take a load of jeeps to the beachhead

27:31 WOW, Centaur, AA Mk I - only 95 were produced.

[@colbeausabre8842]

Yes, the Luftwaffe was much less of a threat than had been anticipated. The Centaur AA and CS were the only members of the family that saw combat. A troop of four AA tanks was in the HQ squadron of each tank regiment and the Royal Marine Armored Support Group operated 80 95mm gun armed Mark IV Close Support tanks. Centaur was the Liberty engined member of the Centaur-Cromwell family and Cromwell was the Meteor (derived from the Merlin) engined version - which was much preferred. tanks-encyclopedia.com/ww2/gb/A27L_Cruiser_MkVII_Centaur.php en.wikipedia.org/wiki/Royal_Marines_Armoured_Support_Group And try the Sherman BARV - the only Army vehicle with its own diver en.wikipedia.org/wiki/Beach_armoured_recovery_vehicle

Excellent video. I read about some of the weirder ideas 'floated' for the invasion, but never any photos.

[@mikhailiagacesa3406]

Wow! All my questions about port logistics answered. Operationally, I'm quivering. I had an opponent who conducted D-Day at LaRochelle'44 in a GDW game( 2 Mulberries; good weather). Looks like we calculated the port capacities and off-loads fairly well.

This is a fascinating collection of photographs of Mulberry and related matters. By coincidence, I am reading Guy Hartcup's book about Mulberry for the second time. This video adds a significant amount of detail. Weymouth being my home town I was also aware of the arrival of the two Phoenix caissons to act a wind breaks for Portland Harbour's Q pier.

Agreed. If there is one thing Britain and the US excelled at beyond all others in WWII, it was logistics.

[@sirrliv]

This was probably one of the most entertaining Wednesday Specials for awhile now. As someone with a particular penchant for military logistics, I've heard of the Mulberry Harbours before, but hadn't heard much detail about them. As with so many off-beat ideas of WWII, I'm delighted at what a ragtag bunch created such a grand invention, thinking so far out of the box and yet finding such a logical solution. There's just one thing that surprises me: that there wasn't more input specifically sought by two groups of mariners in the Mulberry's design. The first was barge towmen, particularly those of the Mississippi River and harbors like New York where single tugboats pulling and pushing massive strings of sometimes up to half a dozen giant steel barges was already a common sight. The second was train ferry operators, both the carfloat men of New York, who specialized in moving hundreds of loaded railway cars a day across the Hudson River on barges, and the self-contained train ferries of the Great Lakes, San Francisco Bay, and even the Channel ports; who would know better about moving colossal amounts of heavy equipment across open water than the captains and engineers who regularly took the railways out to sea, or the design teams that made such carfloat tech happen? Or maybe I'm just an old romantic who wants to see something the size of a small ocean liner disgorge a hundred truck's worth of supplies straight out to the beaches and on along temporary tracks to the front.

[@stewieatb]

at 8:10 Drach nails the best way to deal with the British eccentric: incentivise them with the offer of a slightly bigger shed.

A wonderful story of derring-do, engineering and mad scientists! Beautifully told, as usual. How you compressed all the myriad salient points of this huge operation into half an hour is a wonder in itself. Bravo!

[@shanemossmoss]

[@simonkevnorris]

That was fascinating. I had visited Normandy in 1989 and saw the remains of the Mulberry Harbour. The fact that pieces of the harbour were used to help the Dutch with the flooding in the 1950SaaS also interesting.

[@swsfrancais7289]

Thank you for this video. I grew up on the Conwy Estuary, North Wales & only recently found out the story that many of the Mulberry components were built on the banks of the river. However, your video highlights the fact that some incredible forethought had gone into this project. Tell me if I've missed something but I've not seen a documentary about how & who did all the planning prior to D-Day. I think that story must be worth telling.

[@cbbees1468]

Thanks for the info on this, I remember reading history books on this as a kid and they typically nonchalantly talked about towing or building a harbor and was baffled as to how that would work.

[@richardw64]

The first time I have seen a documentary about the makeshift harbour. Well done Dr Drach. The upkeep of these structures till the end of their use must have been an experience, with irregular weather and fast tides threatening them

[@GrumpyGrobbyGamer]

Wonderful topic, and well presented. A ton of information to digest about a topic that isn't ignored, but largely overlooked in the history of WWII naratives. Everything the Allies were able to achieve after they landed on the beaches was directly a result of the planning and heroic efforts made by the people that built and maintained these harbors.

[@mlbs4803]

A friend's father served as a mechanic on one of the ocean going tugs on D Day. He said that he didn't see D Day as he was below decks keeping the engine going, but he sure heard it! The tug's job on that day was to pull or push disabled larger vessels out of the way.

The sheer scale of this is mind boggling, is this the single largest feat of battlefield engineering in history?

In the immediate face of an enemy, possibly. Otherwise, for scale, Ulithi and Tinian in the Pacific must have been larger undertakings.

[@Voron_Aggrav]

yes and no, Taiwan is an island, so the logistics side can be handled much easier, as you don't need Millions of soldiers, Tanks and other stuff for it, Mulberry was designed to spearhead the invasion of France and the European Mainland, where Germany could potentially send multiple army groups to deal with the invasion, but yes China would need extensive logistics networks in the form of auxiliaries and transport helicopters to facilitate that invasion as it'll be a long and brutal fight, and for the short of it, they don't have the experience nor the capabilities as far as I'm aware to make that work, even without any external factors

[@salvadorsempere1701]

@@Voron_Aggrav An island with a standing army of 300.000 and 3.000.000 reservists. So, yes, you need a million-sized (or close) invading force

[@Voron_Aggrav]

@@salvadorsempere1701 yes, but they don't need to support that army moving halfway into France and Belgium, most of the fighting will be for the beachheads, moment they're established it's pretty much over, so the logistics strain wouldn't be as massive
