This idea of cavalry serving in the double role of infantry and cavalry is a distinctly American development, a trick which the Federal and Confederate armies taught the world during the Civil War, and of which the British made excellent use in South Africa against the Boers. The fact which this war has established, however, is that the older use of cavalry, in the charge against infantry, artillery and even entrenched positions is still of great value. The idea had developed from the tactics so largely employed in the Civil War of using the cavalry as mounted infantry, that the increased deadliness of modern weapons would make this use of cavalry the sole use.
Now, however, it seems that not even the lance is to be discounted. Given the opportunity to reach his objective, the lance becomes a terrible weapon in the hands of the horseman. In hand-to-hand fighting the man with the rifle and bayonet has some chance against the mounted man with the saber. While fighting upward from a lower level he has a pretty long reach, and the advantage of being completely in control of his own movements, whereas even the most expert horseman cannot control the step and movement of his mount as well as a man can control his own. Barring fire, however, the infantryman has no chance against the lance, with the speed and momentum of the mounted man behind it.
So, for this reason, though they are cumbersome weapons under ordinary circumstances, and make a detachment equipped with them much more likely to be seen, lances were retained by many of the British cavalry regiments, just as the German Uhlans retained them.
CAVALRY'S IMPORTANT SERVICE.
One of the most important services which cavalry fulfills in modern warfare is that of drawing the enemy's fire at the time his positions are being approached. This is done to obtain some idea of his force and the disposition of his guns.
Cavalry detachments are sent scurrying across the front, as though threatening an attack, deliberately furnishing a mark for the enemy gunners that this object of ascertaining his strength may be attained.
The more ordinary work of scouting, advance guard work, and riding wide on the flanks of an advancing force are parts of the cavalryman's work which are more familiar.
In the European conflict with tremendous concentration of troops and continued occupation of the same territory the foraging feature of cavalry work disappeared. It is no longer possible for an army to "live on the country as it goes." Food and supplies must be brought up from depots in the rear through an entirely separate and specialized department of the military organization, which does its work with a celerity certainly undreamed of in former days, even as late as our own war with Spain.
In the modern campaign trenches have been developed to such an extent that it is really marvellous how the soldiers live, and to what an extent the "underground fortresses" have been used for living as well as fighting purposes.
In a letter written by a French soldier who took part in a successful raid upon a German trench, he adequately describes the luxuries enjoyed by the German soldiers in the front line trenches in the Marne. The letter was written by a youth who had been wounded in the fight, and was mailed in April, 1917.
