Was America's entry into the First World War crucial to Allied Victory?

After the Germans had been held at the Marne in 1918 it was all over for them.

The scale of casualties gives an idea of the relative involvements of various nationalities,
German 168000
French…95000
British…13000
American…12000

So although the US was in there, they represent less than 10% of the fatalities, but of course their contribution tied up enough Germans to make their operation fail.

The Germans had targeted the French armies as they had thought these were most likely to break, there had been mutinies etc but this completely misunderstood the French mentality, they were not protesting so much about the war itself as the useless tactics, their will to fight was every bit as strong as ever and Germany found this out at a high price.

There can be no doubt that the French would have been willing to fight for far longer, they were completely committed to freeing their country, a longer war would have utterly bled Germany white.

US forces decisive, well no, but significant, it is still most likely that Germany would have failed in their attempt to reach Paris, but I would say that the obvious reality that the US was going to become far more involved was the single most decisive factor in Germany deciding to surrender when it did.

The Germans had overextended and overexpended themselves, along with this the British had developed (mainly the Canadians and Australians) the rolling barrage, co-ordinated use of tanks, and aircraft in what was in reality the Blitzkrieg style of warfare.

This was demonstrated very effectively in what General Ludendorff descirbed as ‘Germany’s blackest day’ during the battle of Amiens, which started even as the Germans were being held and pushed back at the Marne.

The forces involved were largely British, Australian, and Canadian although there were some regiments of the US 33rd division involved.
The British army at the time was recognised as the best trained and most efficient killing machine of any army including the Germans on the Western front, but then it should have been, given the horrific way it had to learn its trade at the Some and Passchendeale.

My view is that the US contribution was not hugely significant militarily but that it showed the Germans the massive potential that was there, the mere fact of US troops being present at all was the greatest contribution, this is what was decisive.

There is a view that the blockade of Germany by the Western allies imposed a timetable upon Germany, put simply, if Germany had not won the war within a certain timeframe, lack of resources would mean that they would almost certainly lose, and this is why they were much the more aggressive toward the last months of the war.

Now put yourself in the heads of Allies leaders, they must have been aware of what the effect of blockading Germany was, and they must have been aware that time was on their side, as Germany grew weaker, the Allies tended to grow stronger, and militarily they became better armies

There is no reason at all to suppose that the Allies would have been prepared to come to an armistice that was favourable to Germany, the French, quite frankly, wanted to annihilate Germany, they were the ones who wanted to destroy Germany completely, and it was Wilson who held them in check.

If Wilson had not been there as a moderating voice I would have expected that France would have exacted a far higher price on Germany, larger parts of the country would have been occupied, and the country would have been broken up into its pre-1870 elements.

This position takes for granted that even without US support there would have been a war ending with capitulation by the Central Powers rather than a negotiated armistice by powers still standing on the field.

Do you truly believe that this would have happened without the US?

As my previous post would indicate I think that this was specifically what the US brought to the table; a sledgehammer that was big enough for Ludendorff to just throw in the towel rather than be struck by it.

No mention was made about there not being US support, but that is quite differant to actual entry into combat.

Without US material support the Germans would have been in a far better position.

The presence of US troops was decisive in that it ended the war, but it would not have changed the result, their presence was mainly a sideline when compared to the numbers already committed.

Had the US not been there on the battlefield then Germany would have fought longer, and been completely destroyed, the British army was suprerior to all other combat troops on the front at the time, and by quite a margin, the French were perhaps even more determined to destroy

It would not have been pretty, and the US would have been even more pre-eminent after the war as Europe would have been more devastated.

I think that the US presence was a major factor in what happened at Versailles. The other Europeans, emboldened by the surrender, treated Germany as a total loser unworthy of respect, and gave them a treaty whose terms devastated Germany probably as much as the war did.

By support I understand more than material, that is to say a political commitment to conflict.

I do see your point and I agree that had the war dragged on for much longer the Germans would have both lost and been crushed.

I’m taking a position between the two though, where the US is not politically in the war and the German Left after a disappointing early autumn 1918 have gained enough power to propose a favorable armistice to the Allies, without surrender. I can’t quite see how France would a) get Britain to support her in declining and b) enforce a Versailles style peace in that environment.

Wow, I didn’t expect a reply quite this lengthy regarding a little sentence I tacked onto the end of my reply to the Op. ;>

My opinion about future conflict between Germany and Soviet Russia is based on the counterfactual premise that Germany WON the war with all the ramifications that entails. If Germany managed a victory in the absence of US involvement it would have been a major vindication for the conservative elements in German government. The SPD might not have made such huge gains in power and influence in the aftermath, ready as they were to capitulate and settle for 1914 borders back in 1916 when Germany still faced a war on two borders. You also suppose that German socialism and the newly arrived Bolshevik regime had much in common, I have reservations. It is my understanding that the German socialist movement was much more moderate than it’s Russian counterpart, especially the factions that eventually gained supreme power in Soviet Russia. I’m afraid I could go on and on about how differently we view the possibilities of the political landscape in supposing a German victory but it really doesn’t have much to do with the op and my fingers would cramp ;>. Very interesting talking with you Sparc.

Depends on what you mean with victorious. I happen to think that a complete victory by the Central Powers is more or less beyond the scope of speculation. I think the best victory they could ever have gotten was a return to the boarders of 1914.

As for the SPD in 1916 the relevant point is not that year, but the status in 1918. Victory or no victory they had by then achieved a pretty strong power base and it is unreasonable to surmise that this would evaporate at a peace with better conditions, or even a downright victory. To boot they had gained strong support from the Center and Christian Coalition, and not only because of their war politics.

As for the differences between the Bolsheviks and the German Social Democrats I do believe that the similarities were broader than you seem to believe, but as you said this is somewhat of a different debate.
