"The movement of cavalry must be rapid and unexpected, and bear the character of determined confidence; an effort should be made by maneuvering to come suddenly on the enemy's flank. A gentle declivity for the final charge must be sought. The rapid, vigorous, and determined charge in line on to cavalry, riding knee to knee, is what is required." The charge to be made effectual, the horses must be brought up in wind, the gallop must not be begun too early; when begun it must gradually be increased to a fast gallop, the final charge for the last sixty yards made with every horse extended. "Nothing, then, must be left undone to excite the spirit of enthusiasm, even to ferocity; then, and only then, the 'cheer' to be raised." At Waterloo the charge of the heavy brigade, the 1st and 2d Life Guards and King's Dragoon Guards, with the Blues in support, is a good example of a successful attack on cavalry. The French line of cavalry as it advanced presented an imposing appearance. They had ascended the brow of the ridge, when a vigorous fire from Ross' Horse Artillery was opened on to them. In the next moment their trumpets sounded the charge and they rushed to the attack, and as cuirassiers approached the British squares, the Heavy Brigade dashed into them. The shock was terrific. The right of the Life Guards being thrown forward, came first into collision. The right of the French was suddenly thrown out by coming unexpectedly on to a hollow way, and as they passed it the 2d Life Guards came full speed upon them. The French cuirassiers were driven back and pursued until the English brigade came under infantry fire. The charge of the Heavy Cavalry Brigade at Balaklava, under Gen. Scarlett, is another good example, when the Russian cavalry, receiving the British charge at a halt, were entirely overthrown. One of the greatest difficulties after the charge is to know when and how to stop, and it is then that the squadron and troop leaders, well in front of their men, must use all their efforts to carry out the ends of their commander. I think this is the time when a strong whistle carried by the commanding officer and the squadron leaders can be used with good effect. Being an unusual sound, it would attract attention. The battle being over, some of the most serious duties of cavalry commence. If the enemy is victorious, the pursuit has immediately to follow. History points out the difficulty of carrying this out. Uncertainty of the victory, or how far it can be counted on, often delays its commencement. Battles are often ended by nightfall, valuable time is lost, and the golden opportunities are past. An active cavalry leader will, however, without further orders at least, follow with his advanced parties and not lose touch of the enemy. He will soon learn the condition of the enemy, act accordingly, harass his flanks and rear and play upon him with his artillery.
