I take for example the VIIIth corps of the British Army, which was part of multiple operations in Normandy in 1944. If you go through the different operations listed in the article, there are very different outcomes:

  • Operation Epsom: 4 000 British (mostly Scottish) casualties and 3 000 German, and fairly even tank scores
  • Operation Jupiter: 2 000 British casualties and more than 6 000 German, quite a difference
  • Operation Goodwood: 5 000 British and 2 000 German (maybe more since 2 000 is only the number of prisonners), a very good German score: up to 500 tanks destroyed for 100 German
  • Operation Bluecoat: British: 5 000 casualties and 246 tanks, German: more than 100 tanks and probably

Overall, all those operations are considered are partial successes for Allies, since they all contributed in the end to pin down German units, exert attrition on them and leave time and space for American units to break through the forest and at Falaise. This was Montgomery strategy and it succeded from a high point of view.

Looking into the details, however, I am very surprised than the number of casualties had been so varying during the different operations. Especially for Operation Jupiter and Epsom, that went own over similar grounds and with similar units on both sides: the ending result is 3:1 to 1:1.5.

So which factors, for every British operations during the battle of Normandy (6th June to mid-August), led to the different casualty ratio ? Why didn't the British manage to keep a good attrition ratio after, for example Epsom or Jupiter?

    The answer to your last question is basically, as Field Marshal von Moltke observed, "No plan of operations extends with any certainty beyond the first contact with the main hostile force" (or, if you prefer the simplified version in common usage with the British Army today, "No plan survives contact with the enemy") Commented Mar 8, 2020 at 14:42
  • @sempaiscuba I understand that, but I hope there will be more specific explanations that will depend of the answer to the first question Commented Mar 8, 2020 at 14:48

    The factors seem to be adequately explained in the Wikipedia articles you cite. The conditions encountered in each operation were different, so the outcomes were different. The realities of war are that things often simply do not go according to plan. Commented Mar 8, 2020 at 14:57
  • Honestly, unless you have elements about the wideness of the Jupiter offensive versus the narrow front of Epsom operation, I don't see the differences : crops, little towns, artillery, infantry and tanks engaged, many Germans counterattacked, difficulty for British troops to hold and unability to break through.. Commented Mar 8, 2020 at 15:14
  • I don't trust the quoted 6000 German casualties for a single day's fighting in Jupiter. I expect they cited casualties for the wider operation. I'd need to hunt down the source, Sons of the Reich: 2nd SS Panzer Corps, or find another.

The bocage country of Normandy, which the British were just entering subsequent to Operation Jupiter, made offensive action much more difficult. Up to July 2 the British forces were operating almost exclusively in bocage-free Nort-East Normandy.

Sniper-stalking in the bocage, June 1944:

enter image description here

The bocage hedgerows were centuries old hedgerows between the farm fields that in places pre-dated the Norman acquisition of Normandy in the 10th century. They were so tough that tanks, unless specially equipped, were forced over them, exposing the undercarriage to enemy fire.

  • Thanks for the hindsights on bocage country, but I don't understand how it links with the question? Tanks equipped as on your photo were mostly used by Americans, I think Commented Mar 15, 2020 at 19:19

    @totalMongot: Incorrect. Prongs tanks:"The British Royal Electrical and Mechanical Engineers (REME) referred to the devices as "Prongs" .... Six hundred Mark I Prongs were delivered by August, to be fitted to the Sherman V. A further 1,000 Mark II Prongs were produced, to be fitted on Shermans and the M10, and 500 Mark III prongs were manufactured for the Cromwell tank. The Churchill tanks were not considered to need the Prong, but some were equipped with them nonetheless." Commented Mar 15, 2020 at 22:58

Various circumstances of defense and attack preparations

General rule for WW2 operations was that attacking force suffers most casualties breaking trough the defenders fortifications and lines. Of course, the better these preparations are (and harder the terrain) you could expect heavier initial casualties. Defenders on the other hand suffer most casualties from initial artillery and aerial bombardment, and latter if the lines are breached trying to counter-attack or worse being surrounded, cut-off, routed and destroyed. Let's see how this apply in given examples.

For Operation Epsom, it must be noted that German defensive preparations were not that great, because they didn't have time to build elaborate fortifications inland (their efforts before the Normandy landings were concentrated mostly on Atlantic Wall) . Also, natural obstacles (bocage above everything else) were not that great in this part of Normandy. However, British on their part had problems of their own. Air support was sporadic due to the bad weather. British artillery never had firepower of let's say Soviets or even Americans. In fact, British artillery doctrine believed in "neutralization" (suppression) rather then outright destruction of enemy forces. As a consequence of this flaw (which will repeat itself in subsequent battles), British failed to achieve decisive breakthrough. Instead, they were pushing slowly forward with Germans being able to reorganize themselves after each British advance. And as a consequence of not being able to decisively breach German defenses, British suffered steady casualties. Germans on the other hand made few errors on their own, with their failed counter-attacks often running into British anti-tank fire and dug-in positions. Main German error was that they were still deluding themselves they could organize armored thrusts that would decisively turn battle in their favor. Overall, they allowed themselves to be drawn into battle of attrition which strategically was better suited for Allies.

For Operation Jupiter, nothing really changed, except that British enjoyed better air support. German casualties (given at more than 6000) are disputed. It is possible that they contain losses from both Epsom and Jupiter. Again, no decisive breakthrough was achieved, but again Germans didn't have continuous defensive line and were sucked into pattern of attack and counter-attack.

Operation Goodwood differed from previous in two important aspects: first, British organized powerful air strikes at the beginning of the operation (including heavy bombers) and second, Germans were able to better prepare themselves, creating continuous defense line and defense in depth with liberal use of minefields. This coupled with positions in Caen itself (buildings used as fortification) helped them to reduce initial casualties. There were fewer German counter-attacks in this battle, possibly because of attrition of their armored forces. On the other hand, British actually relied more on tanks in Goodwood, because their infantry forces already suffered a lot, and manpower shortage after 5 years of war was felt in Britain. As a consequence, losses of armored vehicles were skewed in German favor. However, German forces were already starting to crack, and British did manage to surround and compel to surrender certain units.

Finally, we have Operation Bluecoat. This operation is often forgotten in historiography, because it mainly served to pin-down German forces and support much better known Operation Cobra. Again, it was preceded with heavy air strikes, however they were not that effective because of poor visibility. German defenses were of various quality, sometimes British attacked well-prepared fortifications supported by minefields and sometimes they managed to find gaps in German lines which were crumbling because of constant fighting and Cobra unfolding to the west. Main objective, to pin down German armor, was partially successful . Germans did manage to organize Operation Lüttich, but this failed for various reasons (attrition of German armor in previous months, Allied air superiority, low morale etc ...) . As for casualties, they are hard to discern for this operation, especially on German side because at this point Germans were nearing collapse and records of losses are often intertwined with losses during Cobra and subsequent retreat. For the British, pattern of heavy losses attacking well-defended positions repeats itself, and again we have numerous losses of tanks from anti-tank fire . German did lose some of their tanks in small scale counter-attacks to restore their lines, but overall casualty ratio was again in their favor.

To sum things up, British strategy in Normandy devolved into war of attrition, intentionally or not. They did not manage to create decisive breakthrough (that was left to Americans) but they did sometimes succeeded in luring Germans to counter-attack and subsequently lose men and AFVs. Overall, because of their failure to exploit gains, casualty ratio favored Germans in bitter fighting around Caen. For the German part, mostly because of Allied air superiority and improved anti-tank weapons, they could not employ their preferred tactic of concentrating armor and striking hard at Schwerpunkt. When they did attempt that they more often then not suffered heavy casualties.

  • Thanks for those elements. Should we conclude that air support inflicted more casualties but was not enough for a breakthrough? And that continuous lines were the "mus-have" defense of the time? Also, during Goodwood, besides the minefields, were there lines of infantry and artillery? And were they destroyed by the carpet bombing? Commented Mar 16, 2020 at 9:22
  • @totalMongot Main conclusion of Normandy operations was that carpet bombing, although fearsome, was not nearly precise enough as artillery fire. Therefore, effect was achieved only when really concentrating it on narrow sections of the front. Despite deemed obsolete by many armchair historians, trenches and trench lines, supported by fortified positions and deployed in depth, were most effective means of defense in WW2. Infantry hiding in those had much lesser percentage of casualties from artillery fire and air attacks, then those standing in open. Of course, these were not indestructible.

  • @totalMongot Overall, best strategy for attack in WW2 was concentration of massive artillery fire and aerial strikes on selected sections of the front, then strongly push with infantry and heavy tanks and support guns to achieve breach. Once the breach is achieved reinforce it with anti-tank guns to block possible counter-attacks and launch your mechanized forces to exploit it, attack enemy rear area units, surround the enemy etc . Unlike Americans, British failed to achieve significant breakthrough (for various tactical and technological reasons) and only really moved forward after Cobra.

Especially for Operation Jupiter and Epsom, that went own over similar grounds and with similar units on both sides: the ending result is 3:1 to 1:1.5.

According to my research, while the British numbers are correct, the cited 6,469 German casualties for Operation Jupiter are incorrect. They're the wrong numbers for the wrong period.

The 2,000 British casualties comes from footnote 28 of Sons of the Reich. They appear to be correct.

The Official British History admits to 2,000 casualties. As examples: 5 DCLI lost 254 men; 5 Dorset [lost] 208 and 4 SLI [lost] 189. In less than twelves hours in Eterville on 11 Jul, after it relieved the 9 Cameronians, 2 Glasgow [Highlanders] suffered eighty-five casualties from mortar fire alone.

For German casualties, Wikipedia cites Sons of the Reich page 50.

[10th SS Panzer Division] Frundsberg's losses now amounted to 2,289 killed, wounded and missing and the [9th SS Panzer Division] Hohenstaufen's 1,891.

But this is the wrong citation. It is after Operation Goodwood, a week after Operation Jupiter. And it's their total casualties while the British casualties are for the two days of Operation Jupiter.

Page 43 covers Operation Jupiter casualties, but repeats the same numbers, and for two weeks, not two days.

And the losses of II SS Panzer Corps were now reaching very serious levels. In two weeks' fighting the [9th SS Panzer Division] Hohenstaufen has lost 1,891 men and the [10th SS Panzer Division] Frundsberg 2,289. In terms of armour, the 102nd SS Heavy Panzer Battalion had been reduced to only fourteen operational Tigers by 11 July, with another twelves in short-term repair. Strength returns indicate loses, for one reason or another, of fifteen Panthers, eight Mk IVs and sixteen StuGs for the 9th SS Panzer Regiment and seven Mk IVs and twelve StuGs for the 10th.

Note that's for two weeks fighting, and it's only 4,180 men. If we add in 2,289 again we get 6,469. The Wikipedia editor made a double goof.

This reference offers no German casualty figures for Operation Jupiter alone.

The author describes Operation Jupiter as "a bloody and costly failure".
