The bombardier, and pocket gunner

by Ralph Willett Adye

14. Bridges.—Remark their situation; their length and breadth; the materials of which they are built; their strength, whether sufficient to bear artillery: the roads leading to them: their situation, as to the turnings of the river: their purpose; if to connect towns or villages, the nature, direction, and breadth of the streets leading to them. Observe the country around, whether flat or commanding: study the best means of fortifying the bridge head; and observe the best and most expeditious mode by which the bridge may be destroyed, if necessary.

15. Mountains, Hills.—Amongst high mountains, such as the Alps, roads are very rare; it is seldom more than the vallies that are inhabited and accessible for troops: observe their slopes, if steep or rugged. Examine the positions; means of gaining the summits; and note the state of cultivation and general appearance of the vallies; the pasturage, forage, cottages, villages, castles, roads, paths, and passes. Distinguish the principal chains of hills and their direction. Their relative heights; whether they are sufficiently extensive to form a line of defence; their communications; their strong points; positions proper for batteries, &c. Whether practicable for cavalry and artillery.

16. Coasts.—Their nature; whether bordered by downs; surrounded by rocks, which render their approach dangerous; or by shoals, which make their access impracticable; note the points and headlands proper for forts and batteries to defend the anchorage, ports, harbours, or other accessible parts. If there are any adjacent isles, perhaps they will serve for the erection of advanced batteries, to form a barrier to the efforts of an enemy. Observe the nature of the shores, bays, roads for shipping, &c. with the winds required to go in and out the harbours; and whether they are of easy access: their advantages and disadvantages, their size and depth of water. If a river empties itself on the coast, observe the particular channel for shipping, and whether it can be defended by any of the batteries. If the coast is already fortified, observe all the batteries, forts, or intrenchments, established for its defence, and the protection of the anchorage, &c. Examine the camps and other military posts, which cover the principal points, and the interior of the country. Estimate all the dangers to be run, and all the obstacles to be overcome in a descent, and point out the means of augmenting them. Observe the time of the tide most favourable for approaching the coast. Ascertain the number of artillery and other troops constantly on the coast, and the force that can be collected at a short notice; and how soon they can be drawn to any particular point attacked. Examine the system of defence adopted, and endeavour to improve it.

17. Forts, Redoubts.—Remark their form, whether ancient or modern; whether they are permanent or temporary; elevated or low; revetted or demi-revetted, with stone, brick, or turf. Whether the ditch is wet or dry; fraized or palissaded; natural or artificial. Observe their situation; the face of the adjacent country; whether they effectually command the passes, or protect the country intended. The defence they are capable of making in their present state, and the improvements of which they are susceptible.

18. Castles, Citadels.—Their situation; their form; their extent; their object; the protection they give the city; their connection and communication with it. The present state of their defence, and the improvements of which they are susceptible. Their Souterraines.

19. Villages.—Observe their situation; ascertain the number of families they contain; the nature of the land; the quality and quantity of their crops; their markets; the suburbs that supply these markets; their beasts of burthen: their flocks, herds, poultry, &c. The number of their ovens; quality of the water; stile of houses, barns, stables, and sheep walks. The situation of the church; the nature of the church yard, and its enclosures. The wind and water mills. Observe whether the village is surrounded by hedges, ditches, banks, or walls; whether it can be easily intrenched. Its streets; roads leading to it; and the face of the surrounding country.

20. Cities not fortified.—Their situation; population; commerce; commodities; manufactures; the succours that may be drawn from them, as to men, horses, &c. Their squares and principal buildings. The defence they are susceptible of; whether they are surrounded by walls, old towers, ditches, &c. Their gates, and the roads leading to them. The face of the surrounding country.

21. Fortified Towns.—Their situation with respect to their position, and with respect to other towns in the neighbourhood, whether in the first or second line; the assistance which they can afford each other. The succours that may be drawn from them, or that may be thrown into them in case of a siege. The direction which such relief, whether of men or provisions, ought to take, according to the side attacked; whether they will serve as depots or hospitals. The state of the fortifications (see the word [Fortification] in the alphabet;) their nature; the strength of each front. The rivers in the neighbourhood; the surrounding country within the range of the guns. The form of investment; what lines will be required considering the nature of the country, and the positions; and the means the country affords of executing them. The advantages which the ground would afford between the glacis and the lines, either to the besiegers or besieged; the means of establishing the most certain communications between the different quarters of the army, and the means of cutting them off.

22. Positions.—Every military position ought to possess decided advantages of situation, and ought to be commanded in no part of its front, flank, or rear. All commanding grounds ought to be without the range of cannon. There are four principal objects to be attended to in the choice of a position: 1st. The advantages of the ground; 2d. The supplies for the army; 3d. The objects to be attained; and, 4th. The communications with the rear. The front of a position should be intersected by rivers, ravines, or broken ground, or any other obstacles which can prevent the enemy advancing in order of battle, and oblige him to pass through defilés; but a position becomes useless when the front is so covered by obstacles that the army cannot advance or move out of its camp when necessary; but no obstacles can be too great on the flanks. All obstacles which cover a position, or passes which lead to it, must be within the range of the artillery, or the enemy will pass them unmolested. In a flat country, where the ground does not afford commanding situations, a position is only more or less eligible, as being covered or protected by obstacles; these are very thick woods, in which there are very few roads; large rivulets which cannot be forded or passed without bridges; narrow roads; deep and broken ravines; ground much intersected with hedges, ditches, &c. but it is essential that all these obstacles should be under the fire of the artillery. It is always dangerous to occupy a position, which has its rear so covered by swamps, crossed by rivers or ravines, &c. as to render the retreat of the army difficult. The number of passes by which an army can retire must be examined and secured, and should never be less than 5 or 6. The rivers, brooks, &c. in front of a position, should never be depended upon for a supply of water, as the enemy may cut them off. The ground for a camp should not be too much intersected by hedges, ditches, or ravines, which occasion great intervals in the line, and obstruct the communications through the camp.

In an offensive position it is absolutely necessary that the army should not be too much confined by obstacles, but be at liberty to act in every direction; but in a defensive position, the fewer accessible points there are the better: and if the natural difficulties in front and flank are not sufficient to render an enemy’s attack dangerous, they must be increased by redoubts, intrenchments, abbatis, inundations, &c. The obstacles on the flanks, should also be of such extent that they cannot be easily turned, without the enemy makes a very great circuit; and consequently exposes his own flank, and weakens his line of communication. In case the enemy detaches a body to attack a defensive position in the rear; the front must be sufficiently strong to enable the general to oppose the enemy’s detachment, by a strong body from his own army. In short, the enemy must not be able by any manœuvre to force the army to quit its position. The want of wood or water, or other supplies absolutely necessary for an army, renders every other advantage of a position useless; nor, can a position be long tenable, that is far removed from its depots; and has not its intermediate posts perfectly secure from the attacks of an enemy.
