Insignia of the 32nd Division.
If you've been reading the posts here (and I know that darned few do), you will have been reading a fair amount the British Expeditionary Force, which comprised of units from all of the British Empire, advancing on the Allied left flank.
At the same time, you will have been reading of French advances, although I have not posted any of the campaigns in detail. Suffice it to say, the French were advancing as well, as the headlines indicated.
On this day, the U.S. 32nd Division, which was part of the French Tenth Army, took Juvigny, a strategically important location in the line of the French advance. The 32nd was a National Guard comprised unit made up of units from Wisconsin and Michigan. The unit compelled the Germans to withdraw in their sector and on September 9 the 32nd would become part of the U.S. First Army.
Juvigny is not a battle that's thought much of today, but the accomplishment of the 32nd was significant. Moreover, the event demonstrates that while the U.S. First Army had only come into existence on this day, US units were engaged in the 100 Days Offensive already, attached to French and British commands.
