The Boer artillery began to bombard the British position, dropping shells from the adjacent plateau of Tabanyama at a rate of ten rounds per minute. Meanwhile, Commandant Hendrik Prinsloo of the Carolina Commando captured Aloe Knoll and Conical Hill with some 88 men, while around 300 burghers, mainly of the Pretoria Commando, climbed the kop to launch a frontal assault on the British position. Prinsloo told his men: ""Burghers", we're now going in to attack the enemy and we shan't all be coming back. Do your duty and trust in the Lord." Minutes later, hundreds of Boers swarmed in to attack the British positions at the Spion Kop crestline, much to the surprise of the British. It was very unusual for the Boers to launch a daytime massed attack quickly resulting in vicious, close-quarters combat. This was not a custom of the Boers' style of warfare. The British Lee–Metford and Lee–Enfield rifles were no less deadly than the Boer Mauser rifles. However, both sides exchanged fire at close range and engaged in hand-to-hand combat, with the British wielding fixed bayonets and the Boers wielding hunting knives and their own rifles used as bludgeons. After suffering serious losses, the Boer assault carried the crest line after several minutes of brutal hand-to-hand combat, but could advance no further.
