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.
