To quote Roberts' telegram, "At 3 A.M.

to-day a most dashing advance made by the Canadian Regiment and some engineers, supported by the 1st Gordon Highlanders and 2nd Shropshires, resulted in our gaining a point some 600 yards nearer the enemy, and within eighty yards of his trenches.

This apparently clinched matters." The new position, which passed the power of the Boers to force, enfiladed securely their rifle-trenches along the river, and took in rear the advanced works to the north.

At daylight of Majuba Day, {p.291} Cronje sent Roberts a letter saying that he surrendered unconditionally.
Briefly summarized, this achievement of the British Army was the dislodgment of an inferior force from an extremely formidable position--at Magersfontein--at the least loss to the victors, by a secret and rapid flank march, followed by a swift pursuit, ending in the enforced surrender of a portion that sought escape in flight.
Incidentally, Kimberley was relieved.
