From what we learned, without supplies and troops from America, France and England would have lost

It is impossible not to believe this :cool:

Agreed. But as I've already said they didn't enter the fight until March 1918 & the war allegedly ended in november of that year.
However you're also correct in saying that America's military might tipped the ballance in the allies favour.

It also helped that Pershing refused to allow American troops to be put into the trenches as the French and British wanted.

As I recall, the UK and France wanted to simply use American soldiers as replacements within their own units, not have actual US Army units.

As for the "Bad Generals" meme, it is very common for armies to go thru a rapid turnover in officers and major changes in tactics and doctrine at the start of a major war. There is the old saw about how armies are always ready to re-fight the last war, not the current/up-coming one. Combined with the natural tendency for military forces to promote entirely different kinds of officers in peace versus during war, there is almost guaranteed to be a painful and costly re-learning curve in the early parts of a major war. The US saw it in our own Civil War, in WWI, WWII, and Vietnam. So I am not in the least surprised it happened to the British and French as well.

Diplomatic Relations Faced with a clear German threat of war, Russia backs down. She is still rebuilding from the Russo-Japanese War and is in no way ready for a new one.
The Germans take away from the affair that this is the way to get results from the Russians. “You must always treat Slavs so”, the Kaiser declares.
The Russians resolve that they will never again submit to such humiliation. If a second challenge should come, Russia will accept.

Eastern Front The fortress of Przemysl surrenders to the Russians with 126,000 prisoners and 700 big guns. The Austrian offensives attempting to relieve the fortress have cost another 800,000 casualties. The fall of the fortress leads one German official to complain that Germany is “shackled to a corpse”.

United StatesA rally of 12,000 people at Madison Square Garden cheers Roosevelt, supporting his call for war.

March 22, 1918
Western Front A thick fog hampers morning operations, but it burns off by noon. With their positions and resolve hardened, Byng and Horne’s troops stunt the advance of Below’s 17th Army along the northern sector of the front. But in late afternoon, massive waves of Below’s soldiers dislodge the 3rd Army from the ruins of Vracourt, forcing Byng to withdraw his flanks during the night. At the center of the front, Hutier’s troops relentlessly drive Gough’s 5th Army. Gough’s troops in the south also fall back, surrendering Tergnier and positions on the Oise Canal. By the end of the day, the Germans hold 5th Army’s entire battle zone. There is peril of a break between 3rd and 5th Armies.
Palestine British troops cross the Jordan, aiming to take Amman and cut the Hejaz Railway.
Diplomatic Relations The Dutch government is informed of the impending Allied seizure of their merchant ships abroad.

DT the British had much experience of using colonial types (Canadians, Australians, New Zealanders and South Africans and by 1918 knew that they intended to fight as national elements. Pershing in particular would not and did not allow any interference from the Allies in his army. Sadly this also mean't that most of the lessons that had been learned over three and a half years didn't get passed on to the American officers and soldiers. US casualty rates were every bit as bad as everyone else's had been earlier in the war. Blackjack was one hell of a general but there were a huge amount of Doughboys left in France because of his arrogance.

Of course "Black Jack" wasn't Pershing's original nickname,He started out as an Officer in an African American regiment so You can guess what that nickname was...

Hmmmm, Jack Daniel's...:D

Can that be true? :confused:

I learned that Americans were organized in super-size divisions of almost 30.000 men - iow, Corps-size

It would be interesting to know how the UK and France thought this was possible :confused:

The rapid expansion of the US Army in 1917 brought in a lot of manpower, but there was a shortage of officers for so many new men. The oversized divisions were the result, with a standard number of officers controlling a lot more men. The divisions were powerful, but not much use for anything except head-on attack - there just weren't enough officers to manage any complex maneuvers. Fortunately, the German army of 1918 was not the German army of 1915, or things might have gotten much uglier.
