On April 13th the southern columns were started, but already the British preparations had alarmed the Boers, and Botha, with his main commandos, had slipped south across the line into that very district from which he had been so recently driven.  Viljoen’s commando still remained to the north, and the British troops, pouring in from every side, converged rapidly upon it.  The success of the operations was considerable, though not complete.  The Tantesberg, which had been the rallying-point of the Boers, was occupied, and Roos-Senekal, their latest capital, was taken, with their State papers and treasure.  Viljoen, with a number of followers, slipped through between the columns, but the greater part of the burghers, dashing furiously about like a shoal of fish when they become conscious of the net, were taken by one or other of the columns.  A hundred of the Boksburg commando surrendered en masse, fifty more were taken at Roos-Senekal; forty-one of the formidable Zarps with Schroeder, their leader, were captured in the north by the gallantry and wit of a young Australian officer named Reid; sixty more were hunted down by the indefatigable Vialls, leader of the Bushmen.  From all parts of the district came the same story of captures and surrenders.

Knowing, however, that Botha and Viljoen had slipped through to the south of the railway line, Lord Kitchener determined to rapidly transfer the scene of the operations to that side.  At the end of April, after a fortnight’s work, during which this large district was cropped, but by no means shaved, the troops turned south again.  The results of the operation had been eleven hundred prisoners, almost the same number as French had taken in the south-east, together with a broken Krupp, a pom-pom, and the remains of the big naval gun taken from us at Helvetia.

It was determined that Plumer’s advance upon Pietersburg should not be a mere raid, but that steps should be taken to secure all that he had gained, and to hold the lines of communication.  With this object the 2nd Gordon Highlanders and the 2nd Wiltshires were pushed up along the railroad, followed by Kitchener’s Fighting Scouts.  These troops garrisoned Pietersburg and took possession of Chunies Poort, and other strategic positions.  They also furnished escorts for the convoys which supplied Plumer on the Oliphant River, and they carried out some spirited operations themselves in the neighbourhood of Pietersburg.  Grenfell, who commanded the force, broke up several laagers, and captured a number of prisoners, operations in which he was much assisted by Colenbrander and his men.  Finally the last of the great Creusot guns, the formidable Long Toms, was found mounted near Haenertsburg.  It was the same piece which had in succession scourged Mafeking and Kimberley.  The huge gun, driven to bay, showed its powers by opening an effective fire at ten thousand yards.  The British galloped in upon it, the Boer riflemen were driven off, and the gun was blown up by its faithful gunners.  So by suicide died the last of that iron brood, the four sinister brothers who had wrought much mischief in South Africa.  They and their lesson will live in the history of modern artillery.
