It was deemed indispensable that a map should be provided of the country

for several miles round the encampment, to guide the Generals in the

choice of positions, manœuvres, marches, &c. The district had been

surveyed sixty years before, in common with the general survey of the

south of England, and was drawn on a scale of two inches to a mile. The

better to meet the present requirement, the plans were enlarged and

drawn to a scale of four inches to a mile. All the improvements which

had arisen within the last half century were also supplied, and the

original work corrected where necessary. This was done by taking

magnetic bearings with a prismatic compass and pacing the ground. The

distance examined and corrected, included an area of about 220 square

miles, the cardinal angles of which were Chertsey, Wokingham, Farnham,

and Guildford. All was carried out and completed between the 1st May and

14th June. The principal part of the hills were sketched by Lieutenant

Stotherd, assisted by four non-commissioned officers of the corps, who,

although heretofore wholly employed in the operations of a civil survey,

were, without any previous practice in the art, made to turn their

talents to account in military sketching. The survey—comprised on four

large sheets—was compiled, lithographed, and coloured under the

direction of Captain W. D. Gosset, R.E. Corporal Sinnett drew the

12-inch plan of the encampment furnished for the use of Colonel Vicars.

A special survey of the ground at Aldershot Heath was also made and

plotted on a scale of six inches to a mile, by sergeant Spencer and

corporal Macdonald. The soldiers most conspicuous for their usefulness

in the Chobham survey were—

Sergeant Benjamin Keen Spencer; for surveying, levelling, and hill

sketching.

Corporal William Jenkins; trigonometrical observations, levelling, and

traversing.

Second-corporal James Macdonald; traversing and surveying.

Lance-corporals John Erskine Daveran and Valentine Sinnett; hill

sketching, surveying, &c.

Marking out the encampment was done by the sappers under Colonel

Torrens, assistant quartermaster-general, by driving pickets into the

ground in the places selected to mark the salient points of the

boundaries, to be occupied by the several regiments.

The springs and watercourses were sought for and collected into small

reservoirs or basins, at sites as convenient for access as practicable.

In some places small trenches were excavated, to afford easy channels

for conveying the water to the terraces. These tanks were for domestic

uses. Attached to them were larger ones for washing purposes, which were

filled by the surplus water from the drinking reservoirs through the

agency of small troughs, fixed near the top of the partitional

embankments.

From the dipping and trawling of so many utensils of different kinds

into the tanks, and the constant washing of the water against the sides

of the embankments, it became very dirty and disagreeable. To obviate

this, pumps were fixed in the tanks, large wooden troughs being added to

them to convey the water to the recipients, and sentries being posted

over the reservoirs to compel all parties to take the water from the

approved contrivances instead of resorting to the objectionable mode

which had been attended with so much discomfort.

Where springs could not be found in sufficient number, wells were sunk

to afford water for the troops. Some of these answered excellently, and

yielded a good supply. In several instances the men were interrupted in

the service by the presence of moving quicksand, which prevented them

digging to the depth they otherwise would have done. These wells,

nevertheless, were ultimately made available for use. To keep the ground

from being undermined by the sand, rough sap rollers were at first

constructed and sunk, but as these were found inadequate to meet the

difficulty, on account of the sand oozing through the interstices of the

brushwood, some barrels were securely fixed at the bottom, which at once

offered an effectual resistance to any encroachment, and secured a

serviceable quantity of good clean water. Into several of the wells two

or three bushels of pebbles and shells were thrown to purify the water

in its infiltration. Wells cased or lined with fir poles—an expedient

first resorted to—were found not to answer, as the water collected in

them tasted disagreeably of an impregnation of turpentine. Many failures

in seeking for water occurred. Three or four in elevated parts of the

field were sunk through a stratum of sand and clay to the depth of

thirty-five feet without success. Two artesian wells were also bored

late in July, one to a depth of sixty feet and the other to thirty-five

feet, without any beneficial result.

Tradition or experience was of little avail in selecting places to sink

the wells with anything like certainty of finding water. Nor were any

men present who possessed the occult and mysterious faculty of using the

divining rod to discover it. Several ingenious suggestions were made and

acted on with no better result. All depended upon chance; and to make up

for the deficiency from this source, greater attention was paid to

gathering the nests of springs, and opening up courses and channels for

their unfettered issue into reservoirs. Commonly, depths beyond thirty

feet were obtained without the use of the windlass, or the application

of materials to support the sides. Many of the sappers in these

experiments turned out expert well-diggers, and executed the heavy duty

with energy and coolness.

The formation of lakes was effected by damming up some small brooks and

rivulets, in the valleys which emptied themselves into Virginia Water.

The dams were raised on piles formed from the ends of fir poles, which,

to make a firm foundation, were driven into the ground about ten or

fifteen feet wider at the base than the road was at the top. The sides

were built with good sods, and filled in with the best soil that could

be gathered on the spot. Where the bog was unstable, it was replaced by

stiff clay, which was puddled. In this way two or three fine expansive

sheets of water were formed, which were extremely useful for the cavalry

horses; and a safe and ready passage was also afforded for the troops

across some valleys and morasses over the roadway of the dam. One sheet

was behind the cavalry stabling on Egham Common, and the others, named

“The Great Arm” and “The Little Arm,” were at the base of Black-hill and

of Sheep’s-hill.

The stables were constructed of a uniform width, but the length varied

according to circumstances. For a stable of six horses, the dimensions

were twenty-seven feet by thirteen feet six inches. The uprights or

stanchions were nine feet long, three feet of which were driven into

the ground and well rammed. A wall-plate was then fixed to the

stanchions at the height of six feet from the ground. The rafters were

made of rough poles, secured by a collar-beam four feet from the top,

and then nailed firmly down on the wall-plates, every alternate one

being strapped with hoop-iron. The centre was supported by a king-post

rammed three feet into the ground, and besides being nailed to the

collar-beam, was tied for steadiness and stability at the top with

rope-yarn. Poles were also fixed and secured on either side and at the

ends, which, with the doors, were thatched or wickered with fir

branches, compactly intertwined. The whole was roofed with canvas, and

stayed by guy-ropes. The canvas was made under contract, in pieces to

cover a stable for six horses, but after a few days’ rain the pieces

shrunk about sixteen inches, and caused throughout the period of the

camp much inconvenience to the horses. The stabling was made to

accommodate 1,800 horses at an expense of nearly 1,000_l._ An

experimental stable of the above form was run up in two hours and a

quarter by twelve men, under sergeant George Pringle, directed by

Lieutenant Drake, in the presence of the Commander-in-Chief—Viscount

Hardinge—who expressed his satisfaction both with the exertions of the

men and the suitability of the construction.

The camp-kitchen for the sappers was built six feet wide and ten feet

long, and was approached by a ramp. The flues were ten feet long and one

foot wide, with a space intervening through the entire length of twenty

inches, which was six inches deep in front and lessened to nothing as it

neared the neck of the chimney, for the purpose of facilitating the

action of the air and producing a rapid draught. Its sides were built up

with sods to the height of fourteen inches, and the top was covered over

with the blades of broken shovels. Intervals of nine inches were left to

receive the camp-kettles. A trench was dug round the kitchen from which

at one end rose, to the height of above six feet, a mud stack containing

two distinct chimneys shaped into ornamental pots. At the other end, the

two fires were lighted. The flues were kept independently of each other,

and, with the chimney-stack, were plastered both inside and out with

clay. This expedient gave to the kitchen a neat appearance, and

sufficient durability to stand the wear and tear of constant use.

Sometimes it was converted into an oven by removing the kettles, and

temporarily closing the open spaces with sods. The kitchen cooked for

100 men. Though somewhat troublesome to inexperienced men to construct,

compared with the old Peninsular _range_ adopted by some regiments in

camp, it was a decided improvement both in form and utility, inasmuch as

it economised fuel, received with readiness the few appliances used in

military cooking, and enabled the culinary art to be carried on with

more alacrity and on a larger scale.

An oven was also constructed after the model of the kitchen with one

flue and chimney only. It was built with bricks made on the spot, from

clay in the vicinity of the camp. Amid so much rusticity and so many

rude campaigning inventions, this oven, from its neatness and success,

was much admired. Sergeant Timothy Sillifant, an ingenious mechanic,

designed both the kitchen and the oven, and superintended their

construction.

Some incidental services executed by the sappers were of a character

which it may not be considered inappropriate to notice. So various were

their duties and so frequent the calls for their assistance, that the

encomiums passed upon them after a full test of their usefulness were

not extravagant when it was said “that in all their capacities, from the

driving of a nail to the marking out of a fortification, they seemed to

be equally as _au fait_ as if each service was their special and sole

vocation.”[122] They repaired and adapted the poor-house at Burrow Hill

for a general hospital; erected a flag-staff for displaying the royal

standard; enclosed a large area of ground with a canvas wall seven feet

high, within which were pitched marquees and different tented

conveniences for the use of the Queen and Her Majesty’s Consort and

guests; and watched and managed the tent-ropes of the royal pavilion,

&c., within the compound. Here likewise they erected a cookhouse of

brick, after the form of their own kitchen, and cut a road about two

miles long, from Colonel Challoner’s plantation to the “Magnet,” as a

carriage drive for Her Majesty. The road led across one of the

artificial sheets of water, and at either side of this causeway was

fixed a temporary railing, which gave it an appearance of strength and

completeness. Contrivances were also adopted for permitting the water to

run freely through the embankment so as to insure the stream rising to

the same level at both sides of the bridge. The road was, moreover, a

useful one, for in manœuvring the troops it was sometimes employed to

accelerate their movements, and the passage across it formed a grand

feature in the reviews. It was called the “Queen’s Road,” and the dam

across the sheet of water was dignified with the name of the “Queen’s

Bridge.” The sappers also attended to the pitching and adjusting of the

marquees of some of the staff officers; drained the camp ground; taught

soldiers of the line the readiest methods of effecting these duties, and

built several sentry-boxes. One was erected under the superintendence of

a French captain, of rough poles driven into the ground in a circle,

after the manner of the initial gabion. In front, one stake was omitted

for the entrance. The box was built to the usual height, was covered in

with a conical top, and the whole was thatched with, straw in courses,

which gave it in the distance, when the sun was shining upon it, the

semblance of a richly-flounced dress. Another box of this kind revolved

on a pivot at pleasure, to screen the sentry from wind or rain; and

after the camp was broken up, it was given a place in the grounds of

Colonel Challoner. A third was run up by private James Queen,[123]

which, from its mechanical pretensions, was applauded as a work of

taste, but could never be successfully imitated unless by talented

workmen accustomed to build with neatness and exactness. The structure

was of a mural character and defensible, having loopholes in its sides

and rear. An heroic bust, made of clay by the private, who had shown

some aptitude as a sculptor, was to have surmounted the box, but it was

unfortunately destroyed by some of his comrades, during an excited

criticism upon its merits.

“Much as we admired,” wrote a London daily journal, “the universal

utility of the corps, we thought we had seen the extent of their

capacities, but when looking a little more into the variety of their

employment we found them in a new sphere, and discovered that corporal

Richard J. Letton had been, under Mr. Smith, discharging the details

connected with the Post-office with the usual off-hand success which

seems to pertain to the corps.”[124] The receiving-office at the

“Magnet,” was a sub one to the post at Chertsey. The number of letters

sent to and from the camp, as detailed below, from the first day of

opening the office to the day of closing it on the removal of the

troops, shows that it transacted a fair amount of business.

_First division_—from 13th June to 13th

July.

Inwards 33,783

Outwards 29,614

——— 63,397

_Second division_—from 14th July to 20th

August.

Inwards 42,105

Outwards 37,500

——— 79,605

Total 143,002

———

Of these the number of registered letters were 257, and the

postage-stamps sold realized the sum of 123_l._ 17_s._ 3_d._ The number

of letters to the camp showed but little variation through the course of

the month, but those despatched _from_ it were much affected by the

field days, and on one occasion they fell from 1,526 to 601. The

management of the postal arrangements was highly satisfactory, and

reflected great credit upon Mr. Smith and the corporal.[125] The latter,

in a testimonial from his chief, was eulogized for having performed his

duty with the greatest zeal, integrity, and attention.

To give an additional warlike feature to the evolutions of the division,

some temporary field-works were thrown up. These consisted of three

redoubts, two irregular, with faces of very unequal length, on

Oystershell and Catton hills, and one regular, on Sheep’s-hill. The one

on Oystershell-hill was revetted on one of its faces with brushwood and

fir-branches woven upon pickets, while its remaining sides were cased

with sods. The other redoubts were revetted wholly with sods.

Sheep’s-hill redoubt was a square work, with two platforms for one

field-piece each, and its sides in the interior were each sixty feet

long. Four shafts of six feet deep were sunk under its right face, and

the charges, in boxes containing each 100 lbs. of gunpowder, were laid

and tamped ready for explosion on the 6th August. The Queen was present

on that day and witnessed the manœuvres, which were closed by blowing

up the redoubt. At the appointed time, the wires were applied to the

voltaic battery, but from some mismanagement, supposed from the

communication becoming disconnected, the mines did not go off. Two

sappers immediately repaired to the spot where the charges were

chambered, and after removing the earth which covered them, and affixing

in the ordinary way the powder-hose to form the train, Captain Inglis

fired it with portfire, and a successful explosion was the result. The

whole face was blown up. The field-works were completed early in August,

and were only on three or four occasions used in the general operations.

Contingents of men from the guards and the line threw them up. Some of

the sappers acted as overseers, and others took part in the trenches.

The shafts for the mines were dug and the powder placed in them in the

night-time.

A series of seven or eight sub-aqueous mines, fired by voltaic

electricity, were made in Virginia Water, to show the effect of such

expedients if the service rendered recourse to them desirable. The

largest charge fired contained 35 lbs. of powder. The charges were fixed

in tin cans of sizes to suit the bulk of the powder, and fired from the

shore. Sergeant Entwistle and one private had the preparation of the

charges, &c., and Captain Inglis, R.E., invariably fired them. One on

the 12th July was exploded in the presence of the Prince of Wales, and

was successful, a column of water being thrown into the air to a

considerable height.

As soon as the pontoon train and equipment arrived, the corps commenced

and continued for several days to carry out such instructional practice

as was considered essential to render the contemplated bridging perfect.

The train consisted of—

30 cylindrical pontoons,

4 india-rubber ditto,

1 demi india-rubber ditto,

6 carriages,

and the requisite stores, forge, &c., and all were packed on the margin

of Virginia Water on the 25th June, 1853.

In accordance with appointed arrangements, a military display took place

on the 5th July, in the presence of Prince Albert and Her Majesty. Early

in the morning about 8,000 troops were marched to the Water, on the

north side of which an enemy was supposed to have established himself,

represented by the second company of sappers and detachments of the

Grenadier guards and 23rd fusiliers. While a sharp and prolonged attack

was being made upon the brigade of Sir De Lacy Evans at Blacknest

Bridge, a body of sappers 125 strong, directed by a captain and five

subalterns of royal engineers, began to form the pontoon bridge, and to

carry out other subsidiary means for effecting the passage of the lake.

The six carriages of the train, packed with twelve pontoons and their

superstructure, were horsed by the royal artillery, and moved down to

the water’s edge, where they were unloaded. The remaining pontoons,

eighteen in number, had already been stored on the margin of the lake in

readiness for the service. The moment the order was given, the sappers

in fatigue-dress launched the pontoons, and with the greatest silence,

precision, and diligence, formed in forty-five minutes a bridge of

thirty cylinders with two bays across an arm of the lake 324 feet broad.

The pontoons were lashed in intermediate intervals of eight feet apart,

which is considered to be the proper adjustment of buoyancy for the

transport of the varied weights of artillery. While the bridge was

booming out, Her Majesty and His Royal Highness Prince Albert, with

their illustrious guests, embarked in a royally-decorated barge, drew

near the bridge and watched with evident interest the movements and

exertions of the men.

During the operation a party of twenty-one non-commissioned officers and

men, under three subalterns of the royal engineers, formed two rafts and

one demi-raft of the India-rubber pontoons, and rapidly ferried across

the lake four companies of the rifle brigade, who took shelter in the

woods close to the edge of the water. This service was executed in

exactly the same time that was occupied in forming the bridge.

About noon, the cannonade on the left at Blacknest Bridge ceased, and

the supposed enemy, having discovered Lord Seaton’s real intention,

advanced to dispute his passage over the pontoons. Not a moment was now

lost on either side. One wing of the rifles was thrown across, and

forming line on the opposite bank, opened a spirited fire on their

opponents. The batteries also boomed from the south side of the water,

and under cover of the cannonade—for the whole woodland for some minutes

was shrouded in the smoke it occasioned—a battalion of the Grenadier

guards defiled over the bridge. Scarcely had they concealed themselves

in the embowering woods when the sappers, who had left the pontoons for

an interstitial duty, suddenly returned with bundles of fern and brake,

which they strewed over the superstructure to render the passage as

secure as practicable for the batteries and the cavalry. Now followed

two 6-pounder batteries and a 9-pounder battery of 6 guns each, the 6th

Dragoon guards, and a battalion of the Coldstream guards and of the 42nd

Highlanders, with all the staff.

The remainder of Major-General Fane’s brigade of cavalry proceeded by

the iron gate to the high ground on the north side of the lake, whilst

the brigade of Sir De Lacy Evans, now unopposed by the enemy, marched by

Blacknest Bridge to Smith’s lawn, where the troops were reviewed by Her

Majesty. The second company only of the corps was present at the review;

the other companies being necessarily detained with the pontoons.

To provide as much as possible for the safety of the horses in crossing,

the sappers, with an oar extended from man to man, lined the bridge at

each side, by which a kind of railing or balustrade was formed from one

end of the bridge to the other. The plan had unquestionable advantages

in encouraging the horses and retaining them in their places, but it was

somewhat dangerous to the men. As the second battery approached the

middle of the stream, the floating motion of the bridge caused some of

the horses to become restive, and in the efforts made to control their

progress, five of the sappers were thrown into the lake. No casualty,

however, happened, and the men, after a little swimming, resumed their

stations on the bridge.

In testimony of the services of the corps on this occasion, Lord Seaton

published the following order from Her Majesty:—

“Horse Guards, 5th July, 1853.

“GENERAL VISCOUNT HARDINGE has received the Queen’s commands to

express Her Majesty’s satisfaction in having witnessed this day the

laying down of the cylindrical pontoon bridge, which was completed in

less than one hour, for the passage of the artillery, cavalry, and

infantry.

“Her Majesty did not fail to remark the order, the silence, and the

perfect acquaintance with every detail, which prevailed throughout all

ranks of the sappers and miners.

“Her Majesty highly appreciates the service of this portion of her

army.

“From the date of its original formation this corps has been

remarkable in the annals of the British army for the scientific

attainments of its officers and the practical knowledge of its men,

and has justly acquired the confidence and esteem of the army by its

skilful arrangements, and by being at all times foremost in the

perilous duties of war. In peace upholding its high reputation by the

useful labours which it so cheerfully performs.

“Viscount Hardinge requests Lord Seaton will convey to Colonel Jones,

of the Royal Engineers, who directed the pontoon train, and to Colonel

Vicars, in charge of the engineer duties in the camp, and to the

officers and men of all ranks of the Royal Sappers and Miners, the

Queen’s approbation of their state of discipline and conduct.

“By command of General Viscount Hardinge.

“(Signed) G. BROWN, _A. G._”

The 11th July was another day of field manœuvring appointed expressly

to experimentalize with the pontoons. Before the arrival of the troops

at the lake, a bridge was quickly formed with twenty-four pontoons, on

the same site as that occupied on the 5th instant, and by the same

detachment. At eleven o’clock a part of the division under Major-General

His Royal Highness the Duke of Cambridge passed over it in the order of

movement detailed below:—

4 companies of the 93rd Highlanders,

13th Light Dragoons,

6 companies of the 93rd,

38th regiment,

17th Lancers,

1st Life Guards,

1 troop of Royal Horse Artillery—six guns,

2 nine-pounder guns; and

4 small ammunition waggons.
