He reached the field, his cycle spun between the eager soldiers, and as he leaped off in the presence of the colonel he fairly thrust the note into his hand, exclaiming at the same time in his zeal, “It’s an order to advance!  The whole Army of the Center is about to attack.”

He called it the Army of the Center at a guess, but names did not matter now.  The colonel glanced at the note, waved his sword above his head and cried in a loud voice: 

“My lads, up and forward!”

The regiment arose with a roar of cheering and began to advance across the fields.  John caught a glimpse of a petty officer, short and small, but as compact and fierce as a panther, driving on men who needed no driving.  “Geronimo is going to make good,” he said to himself.  “He’ll do or die today.”

As he raced back for new orders, if need be, he knew now that fact not fancy told him the battle was growing.  The earth shook not only on right and left but in front also.  A hasty look through the glasses showed little tongues of fire licking up on the horizon before them and he knew that they came from the monster cannon of the Germans who were surely advancing, while the French were advancing also to meet them.

General Vaugirard sprang into his automobile, taking only two of his senior officers with him, while the rest followed on their motor cycles.  As far as John could see on either side the vast rows of French swept across hills and fields.  There was little shouting now and no sound of bands, but presently a shout arose behind them:  “Way for the artillery!”

Then he heard cries, the rumble of wheels and the rapid beat of hoofs.  With an instinctive shudder, lest he be ground to pieces, he pulled from the road, and saw the motor of General Vaugirard turn out also.  Then the great French batteries thundered past to seek positions soon in the fields behind low hills.  He saw them a little later unlimbering and making ready.

The French advance changed from a walk to a trot.  John saw the Parisian regiment, not far away, but at the very front and he knew that among all those ardent souls there was none more ardent than that of the little Apache, Bougainville.  Meanwhile, Vaugirard in his motor kept to the road and the staff on their motor cycles followed closely.

On both flanks the thunder of massed cannon was deepening, and now John, who used his glasses occasionally, was able to see wisps and tendrils of smoke on the eastern and northern horizons.  The tremor in the air was strong and continuous.  It played incessantly upon the drums of his ears, and he found that he could not hear the words of the other aides so well as before.  But there was no succession of crashes.  The sound was more like the roaring of a distant storm.

They advanced another mile, two hundred thousand men, afire with zeal, a whole vast army moved forward as the other French armies were by the hidden hand which they could not see, of which they knew nothing, but the touch of which they could feel.
