  3. The British BEF was only 9% of the total allied forces in France and the Low Countries. The German advance was halted in France as the British with a vastly inferior force stopped them at Arras. Some German soldiers turned and ran. Directive 13, issued by German Supreme Headquarters on 24 May 1940 stated specifically for the annihilation of the French, English and Belgian forces in the Dunkirk pocket. The Luftwaffe was ordered to prevent the escape of the British forces across the English Channel. The German southern advance was stopped at Arras by the British with a numerically inferior force. The Germans never moved much further after. The Germans could not have taken Dunkirk, they would have been badly beaten in and around the town. The Luftwaffe was defeated over Dunkirk by the RAF with the first showing of the Spitfire en-mass. More German than allied planes were destroyed in the Dunkirk pocket. The first defeat of the Nazis in WW2 was in the air by the British over Dunkirk. Only six small warships were sunk at Dunkirk by the Germans as the the effectiveness of the Luftwaffe blunted. The British were retreating after the French collapsed in front of them - a programme already in motion, a programme already in motion before the Germans showed up, as General Gort saw the disjointed performance of the French forces in front of him. If the French collapsed the small BEF had no hope against the large German force heading west. The French were still in front of the British when General Gort decided to take the men back to England, as he did not trust the French in a joint counter-attack. French General Wiegand held a meeting to arrange a counter-attack and never invited General Gort head of the BEF. Gort was under the command of Weigand. Gort heard of the meeting and rushed to be a part. He got there after the French and Belgians had left. He ordered the evacuation having no faith in the elderly French leaders. All armies retreat and regroup when the need is there. There happened to be a body of water in the line of the retreat. Were they to move down the English coast and enter France further west with more men from England? The Germans did not know what was to be the next British or allied move. The Germans could not have taken Dunkirk and they tried. The British retreat operation was carried out as planned and in orderly fashion. All bridges to Dunkirk were destroyed by the allies. The British counter-attack at Arras was with outdated Matilda 1 tanks, which only had machine guns, and a few of the brand new Matilda 2 tanks. The Germans fled in droves. In desperation the Germans turned a 88mm AA gun horizontal and it worked against the Matilda 2 - their conventional anti-tank weapons and tanks could not penetrate the tank. The Matilda 2 would roll over German gun emplacements killing the gunners. Rommel thought he had been hit by a force three times the size, which made them stop and rethink. The Germans countered with their superior numbers pushing back the British who fell back towards Dunkirk. The British resolve and the new Matilda 2 made the Germans sit up and think about a street fight in Dunkirk against a consolidated force still with its weapons and the new Matilda 2 - the 88mm would be useless in Dunkirk streets while the Matilda 2 would be in its element, and the Matlida 2 would have easily destroyed the Panzer mk3s. The Matilda 2 could knock out any German tank at the time, while no German tank could knock it out. The Germans were expecting the Matilda 2 to be shipped over in numbers and for all they knew many were in Dunkirk. The Germans could not stop the tanks coming as the British controlled the skies with a CAP and the waters of the Channel. Not a good prospect for the Germans. A Dunkirk street fight was a fight the German troops were untrained and unequipped for and unwise to get involved in. Von Rundstedt and von Kluge suggested to Hitler that German forces around the Dunkirk pocket cease their advance and consolidate and also to prevent an Allied break out from Dunkirk. Hitler agreed with the support of the Wehrmacht. German preoccupation rightly was with an expected attack from the fluid mainly French and some British forces to the south of the German line, not from dug-in Dunkirk which was too much of a formidable consolidated opponent, taking substantial resources to seize. The German column had Allied troops to each side and in front and there was soft marshland to the south west of Dunkirk unsuitable for tanks. If German forces had engaged in a street battle for Dunkirk, they would be vulnerable on their weak flank from the south. In short the fast moving panzers were now static; German forces attacking Dunkirk in a battle of attrition would have been largely wiped out. The German columns were consolidating their remaining armour and the important resupply from Germany, which was slow as it was via horses, for an expected attack by the British and French from the south. The Germans attacked on a remarkably narrow front. They had over-stretched their supply lines. The Germans had no option but to stop, being more concerned at defending from the mainly French forces in the south which were viewed as a greater threat than Dunkirk. French general Weigand implemented his creation of hedgehogs to attack German lines from the sides, with success - hedgehogs were adopted post war by NATO being a part of the tactics until the 1970s. The Germans were thinking, are the British retreating to England from Dunkirk to move down the English coast and re-enter France further south with fresh forces, including Canadians and the new Matilda 2 tanks, which they feared, and join up with the French forces there? The British could easily do that as they controlled the Channel. This would create one large difficult to combat force. They saw the resolve of outnumbered British forces at Arras. German generals were trying to figure out what was happening. None thought that British troops would retreat to England and stay there. The British never did that sort of thing. The Germans could divert most of their forces south and risk a Dunkirk breakout and then risk being attacked from their rear fighting on two fronts, or stay and consolidate, which they needed to do, awaiting a French/British attack from the south and use some forces and the Luftwaffe to attack Dunkirk, which they did. German forces resumed their attack on Dunkirk for 6 days and failed to seize the port. The plan to break out of the Dunkirk Pocket using British, Belgian and French forces was abandoned as Gort had no confidence in the French. All military school studies since, knowing what the German and allied positions and situations were in 1940, have shown it would have succeeded. This sounds strange, but the Germans were defeated at the Battle of Dunkirk. They tried militarily to seize the port but failed. Only because the British did not trust the French and moved back to England did the Germans eventually occupy the town. The Germans did not let the British get away that is misguided myth, they tried and simply could not seize Dunkirk.

  4. Right after the retreat at Dunkirk, up until early 1941, the British: • Destroyed the German surface fleet. • Destroyed most of the French fleet. • Disabled a major part of the Italian fleet. • Freely moving around the Mediterranean. • Starving Germany of food and resources with the effective Royal Navy blockade. • Beat the Luftwaffe over Dunkirk. • Beat the Luftwaffe in the misnomer the Battle of Britain as Britain was never threatened. • Pushed the Italians out of East Africa. • Decimated the Italian army in North Africa. • Were about to take all the southern Mediterranean coast. • Germany was being bombed from the air with raids of over 100 bombers - 150 over Nuremberg - using the new navigational device, Gee. • A massive air bombing fleet was being assembled. • The RAF shot down over 700 German fighters over Continental Europe in 1941. After the small BEF (only 9% of all allied forces in France) left France in June 1940, the British went on the rampage. So much so Franco told Hitler the British would not win and he would not join in with Germany, fearing British occupation of Spanish territory. The Turkish ambassador stated Britain will win as it has a pool of men in its empire to create an army of 45 million (later an army of 2.6 million moved into Burma). In 1941 the British suppressed an uprising in Iraq, beat the Vichy French in Syria and secured Iran and the oil by invading. The British determined where the battlefields with the Axis were going to be. After France 1940 Germany never had a significant campaign victory over the British Commonwealth ever again in WW2. The Germans FAILED: • To win the Battle of Britain in 1940; • To win the Battle of the Atlantic in 1940/41; • To control the eastern Atlantic; • To control the Mediterranean in 1940/41; • To control North Africa and the Middle East in 1940/41. The British Commonwealth stopped the Nazis/Axis achieving all this well before the USA joined WW2 or even sent lend-lease. Even the expensive German pyrrhic victory in Crete meant little in the end to the Nazis because the Royal Navy still dominated the eastern Mediterranean with Crete not leading to any campaign winning difference.

  10. The Mercedes cars used Bosch mechanical injection. It was fuel thirsty in cars. It was not high pressure direct injection as German plane engines were, being indirect low pressure as it injected into the inlet ports. The operating conditions in cars are quite different with constant revving up and down, cooling and reheating. A car engine rarely operates at its peak performance or efficiency. I had a Mercedes Benz 230SL with this injection. I rebuilt the engine. The Bosch system was very reliable needing no tuning. The injection pump calibration was done at a Bosch dealer. The lines from the injection pump to the cylinders were not the same length. Number 6 cylinder was the furthest away and occasionally this cylinder would flood not firing. Wear rate of the cylinder liners was more on this cylinder. They were pigs to start needing an starting injector in the inlet manifold. But! Third party, electronic contactless ignition using quality ignition plugs, made a massive improvement in starting, acceleration and general performance - I disconnected the starting injector as it was not needed any longer. Number 6 cylinder always fired. The six cylinder long-stroke Mercedes straight-six engine was not particularly refined - rough and noisy. Some design defects for sure. The Jaguar straight-six was a far better engine. The ultimate Jag straight-six engine was the last of the series being electronically fuel injected. If people think I am being pro British I drive a Mercedes Benz, provided to my daughter who is employed by Mercedes Benz.

  32.  @matso3856  In the Battle of Britain planes would land refuel & rearm then go back up again. The equivalent of a attacking German bomber wing with their fighter escorts fighting two planes. Once a German fighter expended it ammunition, it turned away from home, while the British plane went down, rearmed flying back up. In large bomber attacks, the Spitfire fighters would specifically engage the German fighters ASAP, usually over water, using Ground Controlled Interception (GCI). Planes were directed while in flight to intercept. The fighters would either shoot the German planes down or they turned back after exhausting ammunition. The bombers would then be half naked approaching London being prey for the Hurricanes, or having to turn back themselves. But the Spitfires would land refuel and rearm then back up chasing them again. The exceptional engine of WW2 was the Rolls Royce Merlin. But this was being phased out during the war for an engine that had less parts with easier quicker servicing - the Griffon. The Griffon was also more powerful. Training men to service and repair Merlins was an expensive, time consuming, and costly business. This was when planes and experienced ground crews were needed ASAP, so even in war time economies were made. I recall talking to an old guy who was an aero engine mechanic in WW2 - unfortunately no longer here. He said "we fixed things, while Americans changed things." Stuck in a jungle you had to make it work, as there was little to no backup.
