of
French cavalry. Into the thick of the struggling mass the horsemen
charged. This attack had been a surprise. The Germans were cut down in
large numbers. As they scrambled back to the protection of their
trenches, French troops scrambled over with them. Again the infantry
alone was engaged, but this time in the enemy trenches.

Whole squadrons of cavalry were ordered from their horses and also sprang
into the German trenches. Reinforcements were hurried up. The Germans
also rushed up supports; but they had delayed too long.

The Germans broke and fled for safety to the second line trenches.

Immediately the French turned the field pieces captured with the German
trenches upon the fleeing enemy and mowed them down in great numbers.
Others of the French troops fell to work consolidating the newly won
trenches. The big German guns opened again; but by this time the French
were pretty well secured against this arm of fire.

More French reinforcements were rushed up to hold the captured trenches.
Batteries of field guns braved the German shell fire and dashed across
the open to the captured trenches. Immediately these guns were brought
into position, they opened upon the German second line of defense.

From their posts of vantage, mounted upon slight elevations, and from
behind trees and other secure places, the great French guns protected the
advance of the cavalry and infantry.

"It's a terrible sight," agreed Hal, "and yet there will be many more
just as terrible before this war is won."

"Indeed there will," agreed Chester.

"Lieutenant Crawford! Lieutenant Paine!"

It was General Petain who spoke.

"My compliments to General Bordeaux, Lieutenant Paine, and tell him that
the left of the newly won trenches must be held at all hazzards!"

Hal sprang upon a nearby motorcycle and soon was speeding toward
the front.

"Lieutenant Crawford! The same instructions to General Ducal on
the right!"

A moment later Chester was speeding forward.

His message delivered, Hal stopped for a moment to gaze about the
trenches won at such terrible cost.

There had been no time to bury the dead, or even to have the bodies
removed; and the trenches were piled high wit
