I am sorry but there are many studies which support the point that Landing Craft were one of the limiting factors of allied strategy. One of the major points preventing an Allied Invasion of France prior to 1944 was the lack of landing craft to support such a large operation and one of the major limitations to allied strategic planning.
Sure, they were a limiting factor. But was that supply or demand? I would tend towards the latter, given that whilst they were doing everything else the war required, the Allies had to scratchbuild an amphibious force capable of operating in multiple theatres (the Channel, the Mediterranean, the Indian Ocean, the South Pacific, the Central Pacific) on a massive and hitherto unseen scale, and then to move the thing round the world every time they felt like performing another operation.
Apologies, but there is way too much to reply to in a coherent sense - some I agree with, some I do not. However, I do think that you have focused far to closely on the 'numbers' and 'equipment' part. War is not just about the 'galloping hussar swinging a sword above his head', but also about how the forces are utilised and deployed. Again, consider that airborne forces can either be used for the small 'raid' style objectives (early war), or at the key point of focus as part of the critical point in an operation (e.g. as at Sicily, Normandy, Market Garden and Varsity). Your main argument appears to be that the manpower should have been distributed throughout the rest of the army. However, this goes against the key principal of warfare of concentrating maximum strength at the key/critical point. The use of airborne forces allowed a relatively small field army to undertake that. Yes, it would have made a more efficient force (on average), but it would have undermined the Allied (and British) ability to apply force at the key point in an engagement (for example, East of the Orne, Arnhem etc.). The failure of the 82nd at Nijmegan was a fantastic example of how a failure to concentrate at the key point of an engagement would mean that a risky operation could ultimately fail.
My argument isn't that one wants no airborne capability, far from it. Rather that one wants a limited airborne capability (i.e., a division+ in the British case, three+ in the American, allowing for the PTO), built in relation to the availability of transport and the operational uses of this force. Meanwhile, the manpower saved from the additional airborne formations can be distributed through other units to provide quality leadership.
As far as concentration of force goes, there never really was one on a scale which my suggestion would preclude.
But this is precisely the point of Mission Command, part of military doctrine that is still taught from Sandhurst, all the way to Command College and further on. A platoon attack is merely a sequence of section objectives, a company attack is a series of platoon objectives, a battalion attack is a set of company objectives and so on. For example, if I were a sqn commander, I would give each of my platoons my intent and a mission objective (SEEK, DESTROY, DEFEAT, SEIZE etc.) and the troop commander would be free to do what he wants within his AO to achieve his objective.
What is unique and what you clearly identify is that the objectives are all independent objectives assigned to various formations within the division. This is the same mission command, with the objectives and intent being made far prior to the engagement. Yes, the division didn't fight as a formed division, but that was principally because the mission planning part was conducted long before ... you will find that almost no divisions on D-Day arrived as a division and fought as a division. The whole reason that D-Day was such a spectacular success was due to the 'mission command' principal.
Certainly they all fit into the wider divisional objective of securing the invasion's East flank. And yet from a tactical/operational perspective, the key bits are all achieved before the division itself actually came into it. The only real input at a division level here was in planning and in attempting to maintain the goals once they had been achieved. My point is that this really shows where airborne forces were useful and were they were less so.
Taking a bridge or eliminating a gun battery by surprise is one thing that airborne forces did very well. In Normandy these were all objectives assigned to individual battalions or brigades; they were small-scale, pin-point strikes, and rested on rapid relief and (at least in theory) on not having to stay in the line for conventional combat. This was the better use of airborne forces, as opposed to general attempts to control wide areas for long periods.
Yes, Normandy could have been undertaken without the airborne forces, but it would likely have been a more bloody affair. Omaha was a an example (although maybe not comparable) of how the failure of a single component (in this case armoured support) could have affected the landing. With regards to Market Garden, most of the failings were not really those of the airborne forces at the Brigade or Divisional level. There were many facets which affected the failure - the airborne forces achieved and exceeded most of their objectives. Had there been better cooperation at allied and corps level many of the short comings would have been overcome. However, this was one of the main failings of the Western Allies in most aspects of post-Normandy WW2 strategy and not necesarilly something isolated to the airborne.
As far as Market Garden goes, I wouldn't see the airborne forces were blameless. Particularly within 1st Airborne Division there were a number of failures in planning and execution. Certainly not ones to pillory Urqhuart for (particularly as he was new to the job), but they do stand out in hindsight as failures. Concentrating the reconnaissance squadron into a coup de main force stopped it performing its intended role, there really shouldn't have been so much trouble getting through to the bridge on the first day, and the decision to stop in Oosterbeek at nightfall was also somewhat questionable. As far as corps level cooperation goes; Browning's HQ was never intended to have a battlefield role, and cooperation between the divisions wasn't really on the cards anyway due to their already overwhelming requirements and their geographic dispersion. Certainly though one can highlight failures in the ground element going up to Montgomery at the top.
Of course it's hypothetical and arm chair generalling (and a tangent noone has asked for), but I have one suggestion that might have substantially improved 1st Airborne's chances, albeit at great risk. This would be to abandon the idea of follow up lifts altogether, and simply attack Eastwards on the first day with every element of the division that had been dropped. The additional mass should hopefully see the whole group through. Two brigades and some divisional elements would then have to hold the bridge for four/five days, without reinforcement, but hopefully still receiving resupply.
I don't disagree with this at all. While the allies did this for the most part, it simply wasn't possible.
It was certainly possible, it just wasn't done. In North Africa 1st Parachute Brigade dropped in and then spent most of the campaign in the line, suffering pointless attrition. Sicily again saw the American 82nd Airborne committed as infantry for most of the campaign. Italy, again, 1st Airborne Division, 2nd Parachute Brigade, and various American units spent their time mostly as infantry. After Normandy the 82nd and 101st stayed in the line into July, the 6th Airborne stayed in until late August. Market Garden and the Winter of 1944/5 again sees an extended commitment to conventional infantry roles.
To take Normandy as an example, I suggest it would have been far better had 6th Airborne dropped into Normandy, been relieved within a few weeks at most, and been replaced by a conventional infantry division which could just have easily been formed from what was IRL 1st Airborne. The only utility of having a second airborne division was if one wanted to perform drops in rapid succession, but this never really materialized. Similarly, having another infantry division instead of one of the airborne's would have meant that it could be committed to the Bulge, leaving the airbourne to train for their proper role.
Well, yes, but then the British Airborne forces at Arnhem also prevented elements of the Dutch SS from deploying to the other side of the Rhine and further blocking the advance of XXX corps.
The only Dutch SS element I'm aware of at Arnhem was the Wacht Battalion. This was a rather atrocious formation that got largely wiped out in its first engagement with British forces, and it's not particularly hard to see why, given that their advance was led by a marching band.
Certainly one can make the point that Frost's battalion denied Arnhem Bridge to the Germans and thereby forced them to take the long way round (there was a ferry some kilometers upstream). At the same time though, I think my original point really stands; Frost and co would probably not have been allowed to hold the bridge so long if the situation elsewhere had been different.
Apologies for the curt replies ... little one has been on the nintendo too long. There is a fantastic paper on the topic called "Operation Market Garden: The Manpower Factor" which is included as a chapter in Operation Market Garden: The Campaign for the Low Countries, Autumn 1944: Seventy Years On. It examines the manpower effect on the British Army by the Airborne forces stealing the fittest, brightest men of the British Army. It also examines the Guards fixation on 'large and fit' men and the effect this had on drawing men away from the line divisions. The whole Guards Armoured thing was something that I had not considered before. Worth a read.
That one is on the reading list. Certainly the whole "large and fit" aspect, together with potential influences on the army administration by the Guards, is an interesting point. I think the very interesting part there though is that "large and fit" is great for infantrymen, not necessarily brilliant for tankers.
My summary - yes, the airborne forces stole some of the best and brightest of the British Army and their reduction in size may have made the average line division more effective. And yes, the attempt at C2 at the corps and army level was part of what let it down. However, their additional funding, the additional training and their selective nature and their ability to deploy via non-conventional means meant that they could achieve objectives that would otherwise unreachable, and could affect the outcome of strategic operations through operational effect.
Sure, I'm not suggesting that the airborne forces were valueless, rather that their relative value declined as their size increased.
