On the return of these two expeditions no attempt was made to keep up a regular balloon section. What was done must for the most part be credited to the energy of those few officers who believed in the future of balloons. Majors Elsdale and Templer ran the factory for building balloons and making hydrogen, and a few non-commissioned officers, trained in balloon work, were held on the strength of depot companies. Most of the practice, in observation of gunfire and the like, was carried out with captive balloons; the few trips adventured in free balloons were undertaken only when the gas had so deteriorated that the balloon had not lift enough for captive work. Major Elsdale did what he could to improve equipment, and urged that two or three officers should be appointed to give their whole time to balloons and to form the nucleus of a balloon corps. He is himself remembered for his pioneer experiments in aerial photography; he sent up cameras attached to small free balloons, with a clockwork apparatus which exposed the plates at regular intervals and which finally ripped the balloon to bring it to earth again. Major Templer, for his part, took a house at Lidsing, about four miles from Chatham and the same distance from Maidstone, and, in 1887, started a small summer training camp for balloon work in one of the fields adjoining his house. Lieutenants G. E. Phillips and C. F. Close, of the Royal Engineers, attended this camp, which was held again in the following years. In 1889 Lieutenants B. R. Ward and H. B. Jones, also of the Royal Engineers, joined it, and the authorities were soon faced with the necessity of coming to a decision whether balloons should be introduced as a definite part of the service. In that year Lieutenant-General Sir Evelyn Wood was in command of the Aldershot Division; he arranged for a balloon detachment, consisting of Lieutenants Ward and Jones, Sergeant-Major Wise, and some thirty non-commissioned officers and men, to be sent to Aldershot early in the summer to take part in the annual manoeuvres. The experiment was a success. The balloons operated with a force which marched out from Aldershot against a flying column of the enemy encamped near the Frensham ponds. A fortunate piece of observation work is believed to have won Sir Evelyn Wood's favour for the new arm. The balloons were asked to answer the question, 'Has the enemy any outposts in rear of his camp?' Lieutenant Ward made an ascent, and though it was getting dusk and the country was not very open, he was able to see the enemy placing pickets round his camp on the nearer side, but could detect no movement beyond the camp. He reported that there were no outposts in rear of the camp; and a night attack sent out from Aldershot was a complete success.
