As soon as the employment of the Militia had become legally possible, orders to mobilize were issued to the Right Wing of the Natal Carbineers and to one Battery of the Natal Field Artillery; the Commandant of Militia was, at the same time, authorized to issue requisitions on all persons "to furnish such animals, vehicles and other necessary things as may be demanded from them for military use." When, however, reports of threatened risings, with demands for military assistance, were, about the same time, constantly received from Magistrates and others in various parts of the Colony, the Government resolved to mobilize a stronger force than at first intended, and this notwithstanding that later intelligence went to show that the rest of the tribe to which the Trewirgie rebels belonged was loyal. The force, therefore, that mobilized and proceeded from different points on the 10th to concentrate at Thornville Junction, Elandskop and Richmond, consisted of Right and Left Wings, Natal Carbineers (under Major A.C. Townsend and Lieut.-Col. D.W. Mackay, respectively) 675; two sections, C Battery, Natal Field Artillery (Capt. W.S. Bigby); one company, Natal Royal Regiment (Lieut.-Col. A.W. Matterson); two squadrons, Border Mounted Rifles (Lieut.-Col. W. Arnott);[110] one squadron, Natal Police Field Force (Lieut.-Col. G. Mansel, C.M.G.); and detachments, Natal Medical, Natal Telegraph, and Natal Service, Corps.

Colonel, now Brigadier-General, Sir Duncan McKenzie, C.B., K.C.M.G., J.P., V.D., of the Natal Carbineers, was placed in command.[111] General authority to administer martial law was, moreover, delegated to him by the Commandant.[112]

The rapidity with which mobilization and concentration were carried out could not have been surpassed. That fact alone testifies to the excellence and splendid efficiency of the Militia organization. In the case of the B.M.R., orders to mobilize were received at 11 a.m. on the 10th. By 8 p.m. on Sunday the 11th, although having had to march over thirty miles in heavy rain, the regiment, "mobilizing forward," had reached Elandskop, the destination assigned.

The disposition of the forces on the 11th was:

Thornville Junction. Staff; Right Wing, Natal Carbineers; Natal Police. Elandskop. Left Wing, Natal Carbineers; Border Mounted Rifles (Troops D-H). Richmond. One squadron (D), Natal Carbineers; C Battery, Natal Field Artillery; Natal Royal Regiment.

The object of this disposition was to enable a converging movement to take place, from the three points named, on the farm Trewirgie. A simultaneous advance, with exception of the Artillery and Infantry (which remained at Richmond), was accordingly made on the 12th, the intervening country being searched as much as possible en route. On the afternoon of the same day, the troops having completed the drive, combined on the farm Trewirgie, in the immediate vicinity of the scene of outbreak. The brigade then formed was nearly 1,000 strong.

Chief Mveli had, in the meantime, been instructed to co-operate. McKenzie placed on his shoulders the responsibility of finding the rebels, then evidently hiding in the neighbouring forests. The result was that, on the 13th and succeeding days, Mveli, with some 300 of his men, rendered very valuable assistance. The Enon forest, some 1,200 acres in extent, was driven, whilst the kraal and crops belonging to Mjongo were destroyed.

Owing especially to the prompt and energetic assistance of a local farmer (Mr. Gibson), the hiding-places of two of the rebels were ascertained, when both were captured. They were tried on the 13th by a drumhead court-martial and, on its being clearly proved they had participated in the murder of the police, were sentenced to be shot. The sentence was carried out forthwith on a peak overlooking Enon forest, and in the presence of Mveli and his men.

The shooting of these men created a deep impression. News of the incident, which was regarded as just and proper by every loyal Native, spread at once far and wide. Rebelliously disposed Natives realized that the troops had come into the field to adopt stern measures, and put a check on their behaviour accordingly.

As, by this time, everything appeared to be quiet in the district, the column moved on to Richmond on the 14th.
