dressing station on captured ground near Cambrai, during the last great
drive on the British front. The wounded are being brought in by German
prisoners taken during the drive, as seen in the foreground. A typical
scene at a dressing station, where first aid is given the wounded.

_Below_--A dashing attack by French poilus, advancing with full packs,
bayonets fixed, and typical daring and courage. The spirit of the
poilu is admirably illustrated in this snapshot. (_Photo by I.F.S._)]
[Illustration: _Top_--How British fighting men advance to attack after
going over the top, spread out in thin columns. Very different from
mass formations of the enemy and less costly to human life. (_British
Official Photo, from I.F.S._)]

[Illustration: _Bottom_--A remarkable actual war photograph of British
machine gunners operating from German second line; captured in the great
Cambrai drive. The men are coolly preparing mess. (_Copyright, U. &

[Illustration: _Above_--Red Cross men tenderly caring for the
wounded. The services of the American Red Cross were invaluable to the
army in France and won the admiration of all the Allies.

_Below_--Wounded man making his way painfully back to the rear, with
grim determination to keep going and all the grit of the typical
American soldier. (_Official Photos by Signal Corps, U.S.A_.)]

[Illustration: The longest-range field gun in the world, produced by
the Ordnance Department, U.S. Army, for service in France, though the
hostilities ceased before they reached General Pershing. More than a
hundred of these guns are said to have been prepared for shipping to
France, and their range and power would probably have astonished the
Germans, as did the great naval guns, mounted on railway cars and manned
by American seamen, that did such effective work in the closing days
of the conflict. (_U.S. Official Photo_.)]

the German second-line trenches in the forest of Argonne, the scene of
desperate and protracted fighting in the fall of 1918. (_Copyright by
