On 11th November General Murray, with the approval of Sir R. Buller, handed over the command of the Estcourt garrison to Colonel Charles Long, R.H.A., and returned to Maritzburg to direct personally the heavy work falling on the line of communication staff in arranging for the disembarkation and equipment of the reinforcements, whose arrival at Durban was now hourly expected. He had been warned by Headquarters, on the 7th, that these reinforcements would be made up to three brigades and divisional troops, and that Lieut.-General Sir C. F. Clery would be sent in command. On the evening of the 11th the first battalion, the 2nd West Yorkshire, arrived at Durban with the Brigadier of the 2nd brigade, Major-General Hildyard, and was sent on the following day to Estcourt, accompanied by two naval 12-prs. and a 7-pr. manned by a detachment of bluejackets under the command of Lt. H. W. James, R.N.[182] These units reached Estcourt on the 13th. Lt.-General Clery reached Durban on November 15th, and assumed command of the troops south of the Tugela. By the 17th five more battalions and a brigade division of field artillery had landed at that port. The British troops in southern Natal were thus in numerical superiority to the Boer column, moving south of the Tugela. The dates of the disembarkation of the remaining units of the corps for the relief of Ladysmith, to which a fourth brigade was ultimately assigned by Sir R. Buller, are shown in Appendix 7. [Footnote 182: The 12-prs. were replaced at Maritzburg by two others sent up from Durban under command of Lieut. A. Halsey, R.N.] [Sidenote: Nov. 14th. The raid begins.] On the morning of the 14th November, Joubert's men crossed the Tugela and off-saddled on the Colenso plain, pushing patrols forward to Frere and finding there only an observation post of eight of the Natal Mounted Police. These patrols, as well as the large number of horses grazing near Colenso, were observed and reported by the armoured train, which, according to the daily practice of the Estcourt garrison, was sent up the line to reconnoitre in the direction of the Tugela. No mounted troops accompanied these train reconnaissances, but doubtful ground was, as a rule, made good by flankers on foot, detailed when required from the infantry in the train. [Sidenote: Nov. 15th. Disaster to the armoured train.]
