Already in December, 1859, the necessity for some definite engineering instruction for Volunteers was being pointed out, and in January, 1860, the first corps of Volunteer Engineers was created, under the title of the 1st Middlesex Volunteer Engineers. Similar corps were formed in various parts of the country, and by 1867 the number of Volunteer Engineers enrolled was 6,580. At the beginning of 1860 a further proposal was made for the formation of a body which, composed of eminent civil engineers, the general managers of leading lines of railway, and the principal railway contractors or other employers of labour, would undertake a variety of duties considered no less essential in the interests of national defence. There was, in the first place, the question of the transport by rail alike of Volunteers and of the regular forces, either on the occasion of reviews or for the protection of our coasts against an invader. While it was evident that the railways could be efficiently worked only by their own officers, it was no less obvious that plans for the movement of large bodies of men, and especially of troops, with horses, guns, ammunition and stores, should be well considered and prepared long beforehand, and not left for the occasion or the emergency when the need for them would arise. In the next place it was suggested that the engineering talent of the country should be made available for the purpose of supplementing the services of the Royal Engineers in carrying out various defensive works, such as the destruction of railway lines, bridges and roads, the throwing up of earthworks, or the flooding of the lowland districts, with a view to resisting the advance of a possible invader. Finally the great contractors were to be brought into the combination so that they could provide the labour necessary for the execution of these defensive works under the direction of the civil engineers, who themselves would act under the direction of the military commanders. Each of the three groups was to discharge the function for which it was specially adapted, while the co-ordination of the three, for the purpose of strengthening the country's powers of resisting invasion, was expected to add greatly to the value of the proposed organisation.
