Which brings us to the debate about the possibility of an invasion in 1943 – Roundup. Something that a surprising number of historians, and even a few not entirely incompetent generals, have suggested might have been possible, and should have been tried.
There are some points in their favour. The invasions of North Africa definitely took resources that could have been built up in Britain, and therefore slowed things down. (And the withdrawal of the new escort carriers, escort groups, and shipping from the Battle of the Atlantic for the North African adventure, definitely did huge damage in the loss of shipping and supplies, slowing things down further.) As a result the huge buildup in North Africa was much easier to use against Italy before moving on to France. Certainly another distraction or delay … but only if you don’t think that knocking Italy out of the war would make Germany weaker!
But once Sledgehammer [the plan to invade France in 1942] was abandoned, this operation was the only possible way to get US troops into combat in Europe, short of shipping some to Russia. It was also the only possible way of coming close to keeping Roosevelt’s ridiculous promise to the Russians.
[…]
Nonetheless it is wrong to think that the British never had any intention of [mounting Operation] Roundup. Despite what Roosevelt and many other Americans convinced themselves, the British were, at the start of 1942, far more optimistic about the possibility of invading Europe through France in 1943 than they had been about Sledgehammer. Their studies seemed to show that Germany would only have to be weaker, not suddenly collapse, to make invasion in 1943 a realistic possibility. Realistic that is as long as the rest of the plans for training and shipping troops, building and concentrating invasion craft, and moving enough supplies to make it sustainable, all came together.
They didn’t.
For the British, the middle of 1942 revealed how little would be available in time for the middle of 1943. Even on the best assumptions of American training and preparation, there was no chance that the majority of forces for Roundup would not be British … assuming they could supply them either. In practice mid-1942 saw the Axis continue to advance on every front. Burma collapsed; the Allied position in New Guinea was under threat; the Japanese were still expanding to places like Guadalcanal; Rommel was advancing in Egypt; the Germans were advancing on the Caucasian oil fields and towards the Middle East; and more and more was needed just to keep Russia in the war. As a result British troops, shipping and supplies were continuing to flow away from Britain, not towards it.
Much of the Royal Navy was trying to save the dangerous losses caused by [US Chief of Naval Operations Admiral] King’s refusal to have convoys in American waters (too “defensive-minded” he thought.) These alone, the worst eight months of the war, were threatening to scupper Roundup. The rest was so busily deployed in the Indian and Pacific Oceans against the Japanese, or North Atlantic trying to fight supplies through to Russia (a high proportion of tanks and planes defending Moscow were British-supplied), that there was virtually nothing left in the Med to slow Rommel’s advance. The merchant ships surviving the fight across the oceans were actually more vitally needed to take men and equipment from the UK to other places than to bring in a buildup for the UK.
Nor was the American buildup going to plan. Less well-trained troops were becoming available too slowly, could not be shipped in adequate numbers anyway, and were in no condition to face German veterans. (The very best US units to go into action in 1942 – the Marines in Guadalcanal – and 1943 – the 1st Infantry and 1st Armored divisions which were actually professional troops not conscripts in North Africa – had very steep learning curves. Particularly at Kasserine. They were clearly not fit to face German veterans yet.
And American resource buildup was also not up to promises. King and MacArthur were milking supplies far beyond what had originally been agreed under “Germany first”. In practical terms they were doing so for the same reasons the British were: an immediate desperate situation had to be saved before a future ideal one could be pursued.
Nonetheless I have read all sorts of apparently serious suggestions that after North Africa was cleared, or at the very least after Sicily was cleared, an invasion of France should have happened.
Delusional.
