In common with the army, the royal sappers and miners furnished detachments for the camp at Chobham about four miles from Chertsey. The common where the encampment was formed was an extensive tract of waste, varied with hill and dale. The amplitude of the district, its freedom from enclosures, from wood or bush, or from barriers or hedges to mark the boundaries of individual or corporate properties, and its succession of swelling heights, well adapted it for the purposes of an instructional encampment, and for the campaigning evolutions of a concentrated force, assembled less for military parade and display than to realize in degree some of the chequered difficulties and vicissitudes which fill up the hard and comfortless career of an army engaged in the active operations of war. The camp was established on the concave edge of the ridge. Each end was advanced, while the centre with a sweep receded, giving to the position a curved line approaching the segment of a circle. The detachment of sappers was tented south of the ‘Magnet,’ the name given to the hill where the head-quarters were established, and next to the left of the Coldstream guards, close to the road leading across the common to Bagshot. The line regiments which succeeded, fell back from the detachment. To be regimentally correct, the sappers should have been on the right of the Grenadier guards, but the position was chosen for the corps because it was central, prominent, and easily accessible to the troops requiring the use of entrenching tools and field implements. The division, consisting of a due proportion of cavalry, artillery and infantry, was under the orders of Lieutenant-General Lord Seaton, G.C.B. The sappers were among the first troops on the ground. As soon as it was determined to form the camp, the party at Sandhurst—one sergeant and twelve rank and file—was directed to suspend its services at the college, and remove to the encamping district. It commenced work on the 21st of April and ceased on the 7th of May, when it returned to the royal military college to carry out the concluding operations of the term. Lieut. Drake, R.E., commanded this party.
