In manœuvring, especially large bodies of troops, rapid movements in columns at quarter distances ought to be much more attended to than they are.--Masses of such columns, or close columns, as practised by the Duke of Wellington at Paris or elsewhere, can be quickly and scientifically placed or prepared for advancing or retiring in any direction, or for deployment, by simply, when put in motion, marking time and bringing up the shoulder; and by this means gradually producing a change of position or of formation of the whole mass. Deployments can be made from such columns in quick or double-quick time, and with the greatest accuracy, by merely moving in threes or fours to the right or left. What an advantage an army thus instructed would have over one proceeding in the old heavy manner, in seizing hold of a position, or of a point, presenting evident advantages, and that too with perfect safety; for, in case of a sodden attack of cavalry, a quarter-distance column is in security in square in an instant. This column also possesses many advantages over the close column, not only in the superiority and rapidity of its movements, but likewise in its being much less liable to get into disorder in broken ground, or to suffer from cannon, which very soon, if well served, destroy a perfectly solid mass, especially if steady battalions of infantry are also firing into it, as was the case at Talavera, when our Guards in the afternoon made a gallant but injudiciously-directed charge; and when the 48th regiment, on the one hand, and the 45th on the other, taught the French, that breaking through an enemy's line in dense columns would not answer with a British army.--Echelons of these quarter-distance columns would, in many instances, be very superior to lines of battalions or brigades, as they could be moved with rapidity to the points of formation in a new line or position, and without any risk of getting into confusion; commanding officers of corps, their majors and adjutants having only carefully to attend to, judge, and preserve their respective distances; and even in common drill or manœuvres of a single battalion, this ought always to form an important part of the practice and instruction of these officers, who in regimental tactics are, in general, not sufficiently occupied, and consequently are too often found ignorant of their business when obliged to act in brigade, and with this object in view every movement should be performed as if in reference to a corps supposed to be upon either or both flanks, with which they ought to work in unison. Now I must beg the unmilitary reader to imagine a large body of troops thus manœuvring in columns at quarter-distances, or in open columns, or lines formed from them, covered by clouds of sharpshooters, supported by these columns or lines, cannon and cavalry, and he will have at once before him a chief feature in modern warfare, in which science
