1135. Eye splice (Figs. 38, 39, 40, 41).โUnlay a convenient length of rope. Pass one loose strand, a, under one strand of the rope, as shown in fig. 38, forming an eye of the proper size. Pass a second loose strand, b, under the strand of the rope next to the strand which secures a, Fig. 39. Pass the third strand, c, under the strand next to that which secures b, fig. 40. Draw all taut and continue and complete as for a short splice.
Lashings1136. To lash a transom to an upright spar, Fig. 42, transom in front of upright.โA clove hitch is made round the upright a few inches below the transom. The lashing is brought under the transom, up in front of it, horizontally behind the upright, down in front of the transom, and back behind the upright at the level of the bottom of the transom and above the clove hitch. The following turns are kept outside the previous ones on one spar and inside on the other, not riding over the turns already made. Four turns or more are required. A couple of frapping turns are then taken between the spars, around the lashing, and the lashing is finished off either round one of the spars or any part of the lashing through which the rope can be passed. The final clove hitch should never be made around the spar on the side toward which the stress is to come, as it may jam and be difficult to remove. The lashing must be well beaten with handspike or pick handle to tighten it up. This is called a square shears are laid alongside of each other with their butts on the ground, lashing.
1137. Lashing for a pair of shears, Fig. 43.โThe two spars for the points below where the lashing is to be resting on a skid. A clove hitch is made round one spar and the lashing taken loosely eight or nine times about the two spars above it without riding. A couple of frapping turns are then taken between the spars and the lashing is finished off with a clove hitch above the turns on one of the spars. The butts of the spars are then opened out and a sling passed over the fork, to which the block is hooked or lashed, and fore and back guys are made fast with clove hitches to the bottom and top spars, respectively, just above the each spar the distance from the butt to the center of the lashing. Lay two of the spars parallel to each other with an interval a little greater fork, Fig. 44.
1138. To lash three spars together as for a gin or tripod.โMark on than the diameter. Rest their tips on a skid and lay the third spar between them with its butt in the opposite direction so that the marks on the three spars will be in line. Make a clove hitch on one of the outer spars below the lashing and take eight or nine loose turns around the three, as shown in Fig. 45. Take a couple of frapping turns between each pair of spars in succession and finish with a clove hitch on the central spar above the lashing. Pass a sling over the lashing and the tripod is ready for raising.
1139. Holdfasts.โTo prepare a fastening in the ground for the attachment of guys or purchases, stout pickets are driven into the ground one behind the other, in the line of pull. The head of each picket except the last is secured by a lashing to the foot of the picket next behind, Fig. 46. The lashings are tightened by rack sticks, the points of which are driven into the ground to hold them in position. The distance between the stakes should be several times the height of the stake above the ground.
Another form requiring more labor but having much greater strength is called a "deadman," and consists of a log laid in a transverse trench with an inclined trench intersecting it at its middle point. The cable is passed down the inclined trench, takes several round turns on the log, and is fastened to it by half hitches and marlin stopping, Figs. 47, 48, 49. If the cable is to lead horizontally or inclined downward, it should pass over a log at the outlet of the inclined trench, Fig. 48. If the cable is to lead upward, this log is not necessary, but the anchor log must be buried deeper.
FIELD FORTIFICATIONS
1140. Object. The object of field fortifications is two-fold.
1. To increase the fighting power of troops by enabling the soldier to use his weapons with the greatest possible effect.
2. To protect the soldier against the enemy's fire.
1141. How these objects are accomplished.
These objects are accomplished:
1. By means of sheltersโtrenches, redoubts, splinterproofs, etc., which protect the soldier from the enemy's fire.
2. By means of obstaclesโwire entanglements, abatis, pits, etc., which delay the advance of the enemy.
1142. Classification. Field fortifications are usually divided into three classes, hasty intrenchments, deliberate intrenchments and siege works.
Nomenclature of the Trench. The following illustration shows the names of the various parts of the trench.
1143. Hasty intrenchments include trenches dug by troops upon the battlefield to increase their fighting power. They are usually constructed in the presence of the enemy and in haste and embrace three forms viz:โthe lying trench, the kneeling trench, and the standing trench.
1144. Lying trench. (Fig. 2.) This trench gives cover to a man lying down. When intrenching under fire the rifle trench can be constructed by a man lying down. He can mask himself from view in about 10 to 12 minutes and can complete the trench in 40 to 45 minutes. A good method is to dig a trench 18 inches wide back to his knees, roll into it and dig 12 inches wide alongside of it and down to the feet, then roll into the second cut and extend the first one back. Conditions may require men to work in pairs, one firing while the other uses his intrenching tool. Duties are exchanged from time to time until the trench is completed.
Intrenching under fire
The height of the parapet should not exceed 1 foot. This trench affords limited protection against rifle fire and less against shrapnel.
1145. Kneeling trench. (Fig. 3.) Time permitting the lying trench may be enlarged and deepened until the kneeling trench has been constructed. The width of the bottom should be 21/2 feetโpreferably 3 feetโand the relief (distance from bottom of trench to top of parapet) is 3 feetโthe proper height for firing over in a kneeling position.
1146. Standing trench (Fig. 4) has a bottom width of 3 to 31/2 feet and a relief of 41/2 feet which is the proper firing height for men of average stature. As this trench does not give complete cover to men standing in it a passage way should be constructed in rear of it not less than 6 feet below the interior crest. This forms the complete trench (Fig. 5). Figures 6โ7โ8 show simple standing trenches used in the European War.
1147. Deliberate intrenchments comprise trenches and works constructed by troops not in line of battle and are usually intended to enable a small force to resist a much larger one. It frequently happens that hasty intrenchments are developed into deliberate intrenchments and from this stage pass into the domain of siege works.
1148. Fire trenches,โthe trenches which shelter the firing line,โare of different types. No fixed type can be prescribed. The type must be selected with due regard to the terrain, enemy, time, tools, soil, etc., but all should conform to the requirements of a good field of fire, and protection for the troops behind a vertical wall, preferably with some head or over head cover.
The simplest form of fire trench is deep and narrow and has a flat concealed parapet (Fig. 9). When time will permit the simple trench should be planned with a view to developing it into a more complete form (Figs. 10 and 11). In all trenches as soon as practicable a passage wayโ2 feet wide at the bottomโshould be provided, in rear of the firing step, for the men carrying supplies, ammunition, etc., and for the removal of the wounded.
Fig. 9 Fig. 9 Fig. 10 Fig. 10 Fig. 11 Fig. 11 Fig. 12 Fig. 12When the excavated earth is easily removed a fire trench without parapet may be the one best suited to the soil and other conditions affecting the conditions of profile (Fig. 12). The enemy's infantry as well as artillery will generally have great difficulty in seeing this trench. Fig. 13 shows a squad trench. Fig. 14 shows a fire trench provided with protection against shrapnel. This trench is used in the European War.
In the European War the aim in constructing fire trenches seems to be to minimize and localize artillery effect as far as possible. The main excavation along the front is a continuous, very deep, communication, not in itself prepared for active defense. The actual firing is done from banquettes or firing steps just to the front of the passage or from trenches dug as far as 5 or 10 feet in front of the main excavation and reached by short passages. Figs 15 and 16 show the type of this construction. Fig. 17 shows a fire trench with parades and shelter.
