"The choice of camps," he says, "depends on two principles: the one geometrical and the other the effect of genius. The first consists in calculating the distance relative to the number and species of troops which compose the army; the other in seeing all the combinations that may be formed on a given piece of ground, with a given army, and in the choice of that precise combination which is most advantageous. This unacquirable and sublime talent is much superior to the other, and independent of it. Great geniuses have a sort of intuitive knowledge; they see at once the cause and its effect, with the different combinations which unite them--they do not proceed by common rules successively from one idea to another, by slow and languid steps. No, the _whole_ with all its circumstances and various combinations is like a picture, all together present to their mind: these want no geometry, but an age produces few of this kind of men; and, in the common run of Generals, geometry and experience will help them to avoid gross errors. "The perfection of our art would be, no doubt, to find a construction or an order of battle equally proper for all kinds of ground. But this being impossible, the only thing remaining for them to do is to find such a construction and such a formation of the troops as may, with the greatest simplicity, and, consequently velocity, be adapted to those numberless circumstances which occur. This should be the constant subject of their studies, but can never be obtained without geometry." [Illustration: POSITIONS of the BRITISH and SIKH CAMPS on the 4th Feb. 1846 _London, Longman & Co._] February the 8th. Sunday. Dined at half-past six, with my brother officers, at the mess of the 3rd Light Dragoons. They are encamped on our right, at the distance of about a quarter of a mile. As in the field, so at the mess-table, the Lieutenant-Colonel of this fine corps, Colonel White, C.B. (now aide-de-camp to the Queen), appeared to be beloved by his officers; indeed they have no small reason to be proud of one, so universally esteemed and respected by the cavalry division of the army of the Sutlej.
