Sir Frederick Roberts had already represented that it would be impolitic to require the native regiments to remain absent from India and their homes for a longer period than two years. In the case of many of the regiments that term was closely approached, and the men after prolonged absence and arduous toil needed rest and were longing to rejoin their families. 'It was not,' in the words of General Chapman, 'with eager desire that the honour of marching to Candahar was sought for, and some commanding officers of experience judged rightly the tempers of their men when they represented for the General's consideration the claims of the regiments they commanded to be relieved as soon as possible from field service.... The enthusiasm which carried Sir Frederick Roberts' force with exceptional rapidity to Candahar was an after-growth evolved by the enterprise itself, and came as a response to the unfailing spirit which animated the leader himself.' The constitution of the force was made known by the general orders published on 3d August. It consisted of three batteries of artillery commanded by Colonel Alured Johnson; of a cavalry brigade of four regiments commanded by Brigadier-General Hugh Gough; and of an infantry division of three brigades commanded by Major-General John Ross. The first brigade was commanded by Brigadier-General Herbert Macpherson, the second by Brigadier-General T. D. Baker, and the third by Brigadier-General Charles Macgregor. Colonel Chapman, R.A., who had served in the same capacity with Sir Donald Stewart, was now Roberts' chief of staff. The marching out strength of the column was about 10,000 men, of whom 2835 were Europeans. Speed being an object and since the column might have to traverse rough ground, no wheeled artillery or transport accompanied it; the guns were carried on mules, the baggage was severely cut down, the supplies carried were reduced to a minimum, and the transport animals, numbering 8590, consisted of mules, ponies, and donkeys. It was known that the country could supply flour, sheep, and forage.
