The Tell of the Tape: Riflemen on the Western Front

On this day, in 1918, the Allies had 1,340,000 combat troops on the Western Front.  The Germans, 1,569,000, a considerable German advantage.

This doesn't, of course, take into account the Austrians, now teetering on the brink of exhaustion, and heavily committed in Italy.  Nonetheless, the Central Powers had a definite advantage, even if it was one that they had failed to make even greater. They could have greatly bolstered earlier, and on this day, if they were less committed in the East, irrespective of the war in the East being over.  And while the United States still have only a few divisions in France their numbers were increasing every day.

By mid June, Americans arriving in France would boost Allied numbers to the point where it intersected with German combat losses for a German Army that was heavily drained by the German Spring Offensive.  And the Germans would decline every month thereafter.  The Allies would peak out in September and then decline themselves, but still retain a huge advantage over a much depleted Germany.

The Spring Offensive followed by the 100 Days Offensive.
