on the 6th of June 1944 Allied Forces launched the largest combined aircan land operation in the history of warfare D-Day the Normandy Landings were one of the true turning points of the second world war and marked the beginning of the long and costly campaign to liberate Europe from German occupation in our new three-part series we'll uncover all the elements of D-Day with episodes exploring the fighting at Sea in the air and on land this first episode will'll focus on the naval side that made D-Day possible known as Operation Neptune why did the Allies select the Normandy beaches how did Allied Naval guns help turn the tide of the battle and why did the Allies almost canceled eay altogether but before we answer those questions a word from our sponsor World of Warships World of

back to galipoli one of the lessons there is being able to concentrate your force in sufficient strength and not only can It capture the beach it can then break out and so when planning the biggest amphibious operation of all fundamentally everything was based on that principle the first problem for the Allies was choosing where to land the shortest and simplest route into France was via the P Cal but the Germans were expecting an attack there and the whole area was strongly defended kotona and Britany were more appealing but as peninsulas they could easily be sealed off by German forces Normandy was the best option leading directly into the heartland of France but before any Landing places could be chosen the beaches had to be studied at close hand one of the key aspects was actually looking at the the physical nature of the beach itself they discovered at DF in 1942 that if the tanks landed on the wrong kind of sand the wrong kind of shingle they would just sink and they couldn't operate at all it was just impossible terrain and so they came up with this way of Landing men secretly in the night often from small canoes they would row ashore they would then take samples analyze the beach they would survey it and bring that intelligence back and that information gathered at Great risk was vitally important to Ramsey and his planners as they worked out exactly where to put the troops ashore a first draft of the DJ plan was signed off at the Quebec conference in August 1943 it proposed Landing the following May with three divisions by sea and another two by air then in January of 1944 American General Dwight D Eisenhower arrived in London to become supreme commander of the Allied expeditionary forces in Europe his headquarters known as scha was responsible for delivering D-Day in command of the naval operations was Admiral Sir Bertram Ramsey having organized the British evacuation from Dunkirk and helped push through the Allied Landings on Sicily he was more than up to the task but Ramsey now faced a problem Eisenhower and his principal Army Commander Berner Montgomery both agreed that the existing plan wasn't strong enough they wanted to land five divisions with three more by air throughout the war landing craft were short there were many competing places that they wanted to use them the Americans had operations already going on across the Pacific there were Landings in the Mediterranean there was a plan for a parallel Landing in the south of France that the Americans were very keen on all of this needed the same limited Naval resources and although landing craft were being made they weren't being made fast enough the outcome of all the discussions was that finally there was an agreement to postpone the landing in the south of France this freed up enough landing craft to be added to those available they were finally able to concentrate sufficient Naval resources to undertake it with less than 5 months to go go preparing for D-Day became a Race Against Time luckily the Allied navies had already won the upper hand over the Creeks marinaa the German ubot threat in the Atlantic had been severely curtailed in the summer of 1943 by a combination of Allied intelligence radar equipped aircraft and Convoy escort groups while the last remaining German surface ships were crippled by the Battle of North Cape and raids on their bases in Norway that allowed millions of United States personnel and millions of tons of War material to arrive safely in Britain and build up in strength for the big event but as the Allies were consolidating their forces the Germans were also building up their defenses under the guidance of field Marshal Irvin RL the desert fox field Marshal Romel was appointed Inspector General of the fortifications at the end of 1943 he discovered they were very patchy and so it was only through his energy and his drive that the defenses themselves began to build up in strength because roml as a veteran of the first world war saw it very much in terms of stopping the landing on the beach the defenses had to be factored in and became a crucial element in deciding when and where to land the Airborne forces needed a full moon to give maximum visibility while the naval forces needed to land at low tide so that any submerged Beach obstacles would be visible and could be removed as quickly as possible such condition itions only emerged for a few days each month and as such the date was set for the 5th of June 1944 but preparations were about to take a turn for the worse on the 27th of April American troops destined for Utah Beach were rehearsing their Landings on slapton Sands in Devon but their exercise was compounded by tragedy first a miscommunication resulted in some troops Landing during the live Naval bombardment then in the early hours of the next morning eight American lsts were jumped by a group of German ebots who appeared out of the dark torpedoed and sank two lsts and badly damaged a third it was a stark reminder of the inherent dangers of amphibious Landings perhaps worse it exacerbated the lack of Allied lsts and risked alerting the Germans to the D-Day plan but still operations continued and by the 31st of May the first troops were embarking there ships for Normandy everybody was getting ready they were all moving into position coming down from the different ports and beginning to collect on the channel and yet one of those factors which was always a severe risk across the English Channel the weather blew up by the very early hours of the 4th of June it was quite clear that the weather was going to be so bad it would jeopardize the whole thing eisenh how took the big decision to delay for 24 hours in the very early hours of the 5ifth of June eisenh Howard faced with the same decision again he knew that these dates were the only ones where the moon and the tide or came together and if he didn't go now it would be at least 2 weeks and probably four before all those conditions would come together again and it's one of those great moments of Jeopardy on the eve of D-Day where we see all of these great issues at stake where the Man In Charge takes a decision and says it's time to go on the 5th of June 1945 for the largest Armada ever to leave British Shores began to make its way to France a multinational force of nearly 7,000 ships and nearly 200,000 Naval Personnel the majority of which came from the Royal Navy the Western task force under rear Admiral Alan Kirk was responsible for Utah and Omaha beaches while the Eastern task force under rear Admiral Sir Philip via took on gold Juno and sword alongside them were the support forces e and l to follow up together they would funnel through a Zone known as Picadilly circus but before they move towards the beaches the first ships into action on the 5th of June were specialized Allied M sweepers Admiral Ramsey in his orders took personal control of this mind sweeping operation because it was so important the first thing to do was to sweep two channels two miles wide from the point where all the ships were going to collect down towards the beaches when the ships collected and went down and headed down through the channels toward the beaches they were going to be headed by a second mine sweeping flotilla which will be making sure that no new mines had been LED in these swept channels since they'v been swept likewise to protect against German ebots the Allies had been sewing mines themselves in the mouths of German Harbors but they needn't have worried seeing the weather German commanders canceled air and sea patrols believing no Landings could possibly take place only when Allied paratroopers hit French soil in the early hours of the 6th of June did the Germans begin to react around 5:00 a.m. a group of German ebots attacked the Eastern task force sinking the Norwegian Destroyer Sven but it was the only loss inflicted by German shipping on the morning of D-Day above the Allied Armada scores of Fighters roam the sky while further out pickets of Destroyers and RAF Coastal command aircraft kept German uots at Bay the first part of the operation was an overwhelming success but having made it across the channel it was now the turn of Allied warships to attack the German defenses their task was to overcome the German Shore batteries to allow Naval operations to go on unhindered and to soften up the beach defenses for the landing forces HMS Belfast was there alongside another Cruiser HMS diadem and they were the two most powerful naval ships engaging the guns around Juno h Belfast is armed principally with 12 6in guns although the naval gunfire was an integral part of the D-Day plan Naval guns themselves are not that well suited for engaging Targets on land the trajectory of Naval guns is very flat whereas to hit a Target on land you really need to go up and down in more of a Howard Shire trajectory shape nevertheless the naval guns were Fair heavy and so they could bombard the targets and even if they didn't destroy them they could knock them out by cussing the Gunners kind of banging on the roof o of each of the concrete casemates and putting the guns out of action that way and that's exactly what happened with the guns of HMS Belfast on the 6th of June Belfast was tasked with engaging the gun battery at lamara Fontaine and she fired for 2 hours from 527 till just before the troops landed at about 7:20 and throughout that time although it didn't destroy the target when the seventh green Howards landed and eventually captured the battery at the end of the morning they were able to report it had been knocked out of action and 50 prisoners were taken simply through the force of Belfast gunfire on the whole the bombardment saw mixed success designed to coincide with Allied air attacks some imp placements were badly damaged While others survived unscathed nonetheless as the bombardment lifted it was the turn of Allied landing craft to go in but before they could reach the shore the Allied troops packed into small landing craft and battered by Channel waves had to deal with overwhelming seasickness the weather in the channel had to cause so much problem didn't completely Abate and the Seas were still very rough packed into the landing craft they were issued with seasickness bags a bit like the ones you get today in modern aircraft the men would throw up into the bag tie the bag pass it to the Man next door' pass it away and they drop it over the side and there's one oral history story from a man called Eric ashro who remembered when this was happening someone shouted and what he was saying is don't throw the bag over cuz my force teeth have fallen in the bag but for many of the men this added to the fear and the terrible conditions and so when they eventually arrived at the beach and the ramp went down this incredibly frightening moment so many of them were just pleased to go back on land and get off the damn sea generally The Landings went well although success varied not only between beaches but Beach sectors themselves where the bombardment was effective Ive Landings accurate and the first wave of Tanks able to offer supporting fire casualties were light but where they didn't casualties were higher in particular on the American Omaha Beach a failed bombardment and sunken tanks combined with difficult terrain to create very bloody fighting some 10,000 Allied casualties were suffered on D-Day at around 1:00 in the afternoon seven of those casualties arrived on HMS Belfast HMS Belfast has a large sick Bay where we're standing now and it's Testament to the size of the ship that the Sick Bay had two surgeons and atist and it's probably for that reason that early in the afternoon on D-Day casualties started to appear off HMS Belfast and were brought on board to come into s Bay that in itself was a fairly procurious procedure the crane operator Stan Finn who was on duty that day remembers the difficulty of lowering a big wooden crate down to the landing craft loading on the casualty on their stretcher gently bringing it on board so they could come down here to the SI Bay it's a testament to another way in which HMS Belfast played a pivotal role in the D-Day operation the major problem on D-Day itself was Supply the tide Rose faster than usual due to strong winds and Engineers already on a strict timetable struggled to remove the explosive rigged obstacles in time damaged landing craft and vehicles clogged the beaches as the space to disembark became narrower and narrow ER these problems in unloading prevented the Allies from building up momentum by the end of the first day many strategic objectives had not been secured and the beaches had not been linked up but despite all the problems dday was still a huge success by the end of the 6th of June some 156,000 Allied troops were ashore an achievement built on the planning and preparation of the naval forces but their work was not over in the the days after D-Day German resistance stiffened and the Allied Ground Forces became embroiled in a brutal slugging match to break out from the beach head German uots in Western Britany began to attack Allied Shipping in the channel though they had some successes they took heavy losses themselves from Allied ships and aircraft now Adept at hunting them down in the main the Allies were able to build their forces for a breakout one of the most difficult things in undertaking a contested landing on the shore is to keep pumping in the supplies and the resources you need to advance and break out the Allies knew that they would not be able to capture a port all the ports have been heavily fortified by the Germans it was going to be impossible to capture one of those in the first instance so the Allies thought about it and came up with a remarkable plan to actually take a couple of Harbors with them these two portable Harbors which became known as the mury harbors and install those in order to allow the rapid disembarkation of vehicles supplies and men over the weeks following The Landings themselves the harbors were up and running within 10 days of D-Day the ingenious design including an outer Breakwater peer heads and floating roadways allowed supplies from large ships to flow in but the mures were put to the test in A Storm 3 days later the American mulbury was put out of action but the Breakwater stayed in place allowing American l L ests to land directly on the beach meanwhile the British mury was repaired using parts from the damaged American Harbor and would continue to supply the Allies all the way until September of 1944 meanwhile further in land the fighting was difficult and costly the Germans had ter Rin on their side while the Allies had to rely on Firepower the ship's guns once they'd engaged on D-Day for them their job wasn't over they continued for the next 5 to 6 weeks off the Normandy coast and as long as the troops remained within range they kept firing in support of their operations Belfast continued to fire for all of that time came back to re ammunition twice but was there supporting the troops until they moved beond Kong the naval gunfire was an integral part of the land operations in making sure that it was sufficiently powerful to break out from within the stres of the beach head itself thanks in part to their overwhelm Firepower and in part their ability to reinforce faster than the Germans by the end of August 1944 the more than 2 million Allied troops now in France were finally able to break out from the German defensive lines they encircled the German forces and race towards the Rind it was the beginning of a new campaign to liberate Western Europe today we tend to take the success of D-Day for granted but at the time nothing was certain and the success of D-Day the operation at self the landing on the beach and then the breakout into Normandy was all built on the success of Admiral Ramsay's meticulous planning he made the naval operation the Bedrock of Overlord itself and the breakout into Normandy
