THE TENTH CHAPTER.
TREATING OF THE DIVERS SORTS OF BRIDGES used in the service of the Lords the States of the Vnited Provinces.
MAny a brave occasion in the warres hath bin lost for want of Bridges to passe over a River a Brook, or a Moate, therefore the States for any peece of service, have alwaies diverse bridges in a readinesse, both small and great. The smaller sort for any suddain enterprise, or for put∣ting over the moat of a Town, a Hom-work, or a Half moon are 3. as first a Corke bridge now not in use, secondly a Bulrush bridge, the peeces whereof are ten foot long, and six or seven foot broad, that foure men may go over them in Front, described unto you in my second part in the Chapter of Approches, figure 159. whereof many peeces being joyned fast together with ropes and Ankors, will lay a bridge over a moate, a brook, or a ditch for men to passe over, the third sort is a wicker, or a basket bridge, as shall be hereafter described.
Moreover they have three sorts of other Bridges, namely, a small boat bridge, with beames, plancks, roaps and ankors, which are carried upon long waggons in the Army, whereof you may see one of them in this treatise, chapter the third, figure ten, of these we have commonly twelve, that goes along with our Army upon a long waggon, drawne with 15. couple of horses, and a Thillet horse.
Besides those above mentioned, there are two great bridges, the one called a punt bridge, which is laid longwaies, end to end over the Rhine, or any other great River, and the other a Maze schip bridge, as you shall see in the figure following.
Command then being given to the Captain of the Bridges and his men, for the first they lade Ordnance, and all manner of equipage in those great Punts, as beames, plancks, cordage, cables, anckors, windlasses, winches, and all other necessaries, to bring them up to the Rendevous.
Now when the Captain of the Bridge is to lay a great Punt bridge over the Rhyne, or the Whale, as at Nemegen, Schencksconce, Wesell, or at Rhenebergh, taking first the breadth, and distance of the River from the one side to the other, they can easily give a gesse, how many of these punts being 50 foot long, and 10. foot broad, will serve to reach over the River. The first punt then be∣ing laid longwise from the edge of the one side of the River being fastened to two great Stakes (and Anckers) driven into the ground, they then lay at the furthest end of the first punt. and other punt laying Brush at both ends of the punts, which rises and falls, that horse and waggons may passe over them, and alwaies fasten and bind them together with ropes and cables which stayes the punts, by casting out ankors and cables into the streame, to hold them fast together, and thus they do till they have laid over 15. or 16. of these long punts which will reach over from the one to the other side of the river, at the end whereof there are cast up two halfe moones, (if it be not neare a Town, and a Steckado or two Gats made, that none may passe over it without leave, ha∣ving alwaies a guard to defend it and keep it from burning.
Number 37 is the figure of a peece of a basket Bridge, such a one as was used at our last en∣terprise upon Hulst, made of wicket, about the bignesse of ones middle finger, with supporters of wickers within it, as hedges, a foot distant one from another, to strengthen it, and helpe it from bending, when one goes over it, being also matted in the bottom, and covered round about with waxed Canvas, being carried between two men, with two coole staves some 13 foot long, as two men carries a hand barrow, being laid crossewise peece to peece, and fastened together with ropes, and at both ends anckors, the length whereof from a to b is 6. foot, and the breadth from c to d two foot and a half, and is a foot in heigth, so that 2 men in front may go over a moat up∣on any surprisall of a Towne.
Number 38 is a Maze bridge laid crossewaies, such a one as our Army passed over the Maze at the Grave, Venlo, and Mastricht, having beames some 15 or 16 foot long, and crosse beames over the Maze schips, with plancks from the one side of the river to the other, and is held fast together by cables and anckors, as the figure following of such a bridge doth demonstrate.
Number 39 is the figure of a Mathematicall Horse watermill, first invented by Vitrivius, and is of singular use for the drayning out of water in Marrish groundes and places, being drawne but with one horse, as the figure demonstrates, and by relieving it with fresh horses and a
