PRECAUTIONS AGAINST CAVALRY.
140.—Cavalry Patrols.
During the whole "approach" watch should be kept for possible cavalry patrols. The elements acting as advance guard and flank guards or as combat patrols have as part of their special mission to keep the cavalry away from the main body.
141.—Face and Fire.
To repulse cavalry, the infantry must be able to face quickly toward the charging horsemen and furnish a heavy fire.
142.—Protective formations.
If cavalry patrols are expected ahead, deployment as skirmishers will secure this, if on the flanks, deploy in columns of squads marching in double file. A formation in echelon is effective at all times.
143.—Repulsing the charge.
If cavalry appears, stop, face the charge quickly, fix bayonets and fire at will, the section leaders controlling the fire.
144.—In case of surprise.
If surprised, deploy quickly and lie down.
