But independent of this comparison as to quantity, there are others in which the Rocket has advantages exclusively its own: there are situations where artillery cannot by any means be brought into action, while there is no situation, no nature of ground, which is passable to an infantry soldier with his musket in his hand, that is not equally to be passed by the Rocketteer with _his_ arm and ammunition. For the accomplishment of any particular service, he may dispense entirely with wheel carriages or even horses; there is nothing which the men themselves cannot transport and bring into action; and if any bombardment were required by a _coup de main_, 1,000 men would not only convey 1,000 rounds of the heaviest Carcass Rockets, a number sufficient to destroy any place within the compass of their range, but would perform that service in a few hours, having neither batteries or platforms to erect, nor mortars to convey. Such are the true principles of this new system of artillery, for (projecting the same ammunition) so it may be called, and the greater the scale of equipment, the greater in proportion will its powers appear; thus, if an establishment were formed on the strength of a cavalry regiment, if 600 mounted men were equipped on the principles of the present detachment, they would take into action, without ammunition horses or wheel carriages, 2,400 rounds of ammunition, and 200 abouches a féu; and if 100 ammunition horses were attached to this corps, it would further possess a reserve of nearly 2,000 rounds more: the whole capable of every movement and service practicable by any other regiment of heavy cavalry; and the same proportionate power would be found to attach to every other mode of equipment. In addition to this view of the powers of the weapon, it is important to state, that the detail of the service is most extraordinarily simple; that there are but a few points to be attended to in its application; and those such as may be most easily acquired; the principal ones are, that care must be taken to fix the sticks very firmly to the Rocket, and in the true direction of the axis of the Rocket, to prevent aberration of flight. That, at high angles, the frame must always be elevated for the large Rockets from 5° to 10° more than the elevation at which the Rocket is intended to be projected, and in the small Rockets from 2½° to 5°; for, as the Rocket leaves the frame before it has obtained its full force, it drops a certain number of degrees in proportion to its weight at going off. Thus the longest ranges of the 32-pounder Carcass Rockets are obtained at about 55°, or rather more, if the Rockets have been long made. An officer, however, being prepared for this circumstance, will soon discover the maximum range of the Rockets he may have to discharge.
