"4. It should have the ground in its front and on its flanks searched out by cavalry, mounted infantry, or native levies. "5. That when mounted troops have found the enemy, they must invariably clear the front of the infantry to enable the latter to use their rifles. "6. That brigades must be so trained that each battalion and individual soldier must know how to get into the best formation with the least possible delay for meeting the attack of the spearmen, who, it must be remembered, can move at least three times as quickly as a British soldier can double. "To carry out the above, a high standard of training and steadiness is required, and battalions must be provided with a liberal supply of cutting tools, felling axes, hand axes and bill hooks to enable them, the instant the battalion marches into bivouac, to cut down small trees or strong branches of prickly trees with which to construct a thorn fence. "Piquets must be withdrawn at dusk, otherwise they might get surrounded and cut off, or, in falling back, would possibly suffer from the defenders of the zereba. "The protection of the zereba against surprise must depend on the vigilance of its sentries and piquets which line the fence, and whose strength will naturally depend on the proximity of the dervishes to the force. With reliable information, and the ground properly reconnoitred, a patrol of ten men per company, patrolling constantly and noiselessly along the inner edge of the zereba, is adequate, so long as the enemy's dem is say 15 miles distant (a day's march); when nearer than this, the strength of the piquets to remain awake and under arms will depend upon the circumstances of the moment. "All night duties of this nature should be found by companies, so that portions of the line along its whole length shall be on duty. Words of command and orders must be given in a low tone; there must be no shouting and no fires burning till the hour arrives for making the morning tea. Men should always be allowed to smoke, but should be warned of the danger of fire in zereba by a cigarette or match-end thrown into dry grass. "Officers must sleep immediately behind their men; a certain number will always be on duty. "All, officers and men, must sleep in their clothes, boots and accoutrements, and each man must have his rifle with him. None but sentries' should be loaded, and bayonets should not be fixed, even by the patrols, except when there is expectancy of attack. Under no circumstances should men sleep with their bayonets fixed, or serious accidents will occur. "And here, one word about 'alarms.' I do not refer to the assembly by bugle sound, but what is ordinarily called a panic, in other words a disgraceful absence of discipline and self-control, which, while ruining the reputation of the corps concerned as a reliable battalion, may be the cause of serious mischief, and must be disastrous to the confidence the General Officer places in its officers and men.
