In a week or so they took heart, returned, and blew up the bridge.

Roving parties of the enemy, composed mainly of the redoubtable Johannesburg police, reappeared even to the south of the river.

Young Lygon was killed, and Colonels Crabbe and Codrington with Captain Trotter, all of the Guards, were severely wounded by such a body, whom they gallantly but injudiciously attempted to arrest when armed only with revolvers.
These wandering patrols who kept the country unsettled, and harassed the farmers who had taken advantage of Lord Roberts's proclamation, were found to have their centre at a point some six miles to the north of Glen, named Karee.

At Karee a formidable line of hills cut the British advance, and these had been occupied by a strong body of the enemy with guns.

Lord Roberts determined to drive them off, and on March 28th Tucker's 7th Division, consisting of Chermside's brigade (Lincolns, Norfolks, Hampshires, and Scottish Borderers), and Wavell's brigade (Cheshires, East Lancashires, North Staffords, and South Wales Borderers), were assembled at Glen.
