American Troops under British and French Command in the Great War.

Yesterday I noted that the US 32nd Division was, at this point, advancing under French command.

They weren't alone.

It's really popular to imagine that General Pershing insisted that the US have its own Army in the field and that he was universally successful. So when Americans marched into battle in France, they did so exclusively under overall U.S. command.

That's a myth.

Indeed, we've already seen here recently that the U.S. First Army was only formed in August and that it only took over the St. Michel Sector on August 30.  But Americans had already been in heavy combat for weeks prior to that as individual divisions were placed under higher foreign commands by necessity.

And that hadn't stopped due to the First Army being formed.

The U.S. 33d and 80th Divisions were part of the British Fourth Army and had been fighting with the British as part of the Second Battle of the Somme, which we've read about here a bit.  The American II Corps was also part of the British Fourth Army and would be up until late October, 1918, by which time it had suffered 11,500 casualties under British command.  

In other words, the II Corps fought under the British Fourth Army until the end of the war as a practical matter with one final U.S. Division remaining under official British command at the war's end.

The 92nd and 93d Divisions, which were made up of black enlisted men, fought the entire war under French command.  The American III Corps was part of the French Sixth Army until mid September, when its two divisions became part of the U.S. First Army. 

In October the 37th and 91st Divisions were attached, by Pershing, to French Army of Belgium, at Foch's request.

All of this is significant in that the role of the U.S. Army is subject to a double set of myths, one being that the U.S. Army fought the whole war under American command and the other being that the US role was minimal.  In fact, while there did come to become a U.S. First Army, U.S. divisions served under French and British command in numbers that became significant during the German 1918 Spring Offensive and throughout the 100 Days Offensive.  While after the formation of the U.S. First Army, American command of its troops in the field became extensive, there was never a day when there were not U.S. soldiers under British and French command, and they were needed.
