Signalling by heliograph was throughout the operations of the greatest value. I had always realised the advantages of a semi-permanent line of signal stations along the communications to the telegraph, but I had doubted the practicability of using such complicated arrangements in action. In this torrid country, where the sun is always shining, the heliograph is always useful. As soon as any hill was taken, communication was established with the brigadier, and no difficulty seemed to be met with, even while the attack was in progress, in sending messages quickly and clearly. In a country intersected by frequent ravines, over which a horse can move but slowly and painfully, it is the surest, the quickest, and indeed the only means of intercommunication. I am delighted to testify to these things, because I had formerly been a scoffer. I have touched on infantry and artillery, and, though a previous chapter has been almost wholly devoted to the cavalry, I cannot resist the desire to get back to the horses and the lances again. The question of sword or lance as the cavalryman's weapon has long been argued, and it may be of interest to consider what are the views of those whose experience is the most recent. Though I have had no opportunity of witnessing the use of the lance, I have heard the opinions of many officers both of the Guides and the 11th Bengal Lancers. All admit or assert that the lance is in this warfare the better weapon. It kills with more certainty and convenience, and there is less danger of the horseman being cut down. As to length, the general opinion seems to be in favour of a shorter spear. This, with a counter poise at the butt, gives as good a reach and is much more useful for close quarters. Major Beatson, one of the most distinguished cavalry officers on the frontier, is a strong advocate of this. Either the pennon should be knotted, or a boss of some sort affixed about eighteen inches below the point. Unless this be done there is a danger of the lance penetrating too far, when it either gets broken or allows the enemy to wriggle up and strike the lancer. This last actually happened on several occasions. Now, in considering the question to what extent a squadron should be armed with lances, the system adopted by the Guides may be of interest. In this warfare it is very often necessary for the cavalryman to dismount and use his carbine. The lance then gets in the way and has to be tied to the saddle. This takes time, and there is usually not much time to spare in cavalry skirmishing. The Guides compromise matters by giving one man in every four a lance. This man, when the others dismount, stays in the saddle and holds their horses. They also give the outer sections of each squadron lances, and these, too, remain mounted, as the drill-book enjoins. But I become too technical.
