"Black Jack" Pershing had launched a Punitive Expedition, which came very close to war with Mexico, and had withdrawn from northern Mexico before Mr. Boldock's unit had arrived on the scene, to guard the Texas border, while Pershing went to France. The Zimmermann Telegram, in which Germany invited Mexico to attack the U.S., enlisting the aid of Japan, was the immediate cause of U.S. entry into WW I. That, though the overture was rejected, and ongoing turmoil within Mexico, were reasons for the U.S. to retain a guard along the border, even while transferring troops to Europe. Most of the 3rd Infantry Division, also went to France, where it became known as the "Rock of the Marne", for its stand during the 2nd Battle of the Marne, in which it helped save Paris, during a major German offensive. The 3rd was also involved in American offensives. Mr. Boldock's unit remained on border duty.
