About the 19th of May, owing to the villainous activities of the guerillas in the north of Cape Colony, Colonel Monro moved to join the troops operating near Steynsburg, and subsequently Colonel Murray crossed into the Cape Colony. Colonel Maxwell (R.E.), to the deep regret of his colleagues and of all who knew of his distinguished services as leader of the Colonial Division under General Brabant, succumbed to the serious injuries received by being thrown from his horse. Early in June Colonel White proceeded to Aliwal North to act in combination with Colonel Haig, who was still chasing Kruitzinger. At this time, in accordance with General Bruce-Hamilton's plan of scouring the country towards Petrusburg, his force was split into seven small columns. More columns, co-operating, advanced from the line of Kaffir River, Jagersfontein Road, Luckhoff, and Koffyfontein, so as to converge on Petrusburg; while Colonel Henry's force co-operated through Wolvekop (near Luckhoff), and the Kimberley column moved near Koffyfontein. Another force, moving from Bloemfontein, operated westward from Kaffir River Station. To block retreat to the north, the South African Constabulary occupied posts along the line of country between Bloemfontein and Petrusburg; and higher up, the Modder River drifts, between Abraham's Kraal and Paardeberg, were guarded by General Knox's troops. The movement took from the 5th to the 8th of June, during which time many laagers were surprised (one by the Burgher Police under Lieutenant Bayley), and 268 prisoners with various stores and effects secured. These activities were followed by others of a similar nature against roving gangs--under the Commandants Brand, Kolbe, and Joubert--which infested the country east of the railway, between the Caledon River on the south, and the line Edenburg-Reddersburg-Dewetsdorp on the north. Fights and skirmishes and snipings continued almost daily, and the columns of Colonels Rochfort, White, and Du Moulin had no reason to complain of lack of excitement. On the west of the railway, Colonels Williams and Byng continued to sweep the districts of Fauresmith, Jacobsdal, and Philippolis. MAJOR-GENERAL C. KNOX, ORANGE RIVER COLONY (CENTRE)
