As the Afghans wavered, the green standards on the mountain moved down to assist them in a last rally. Which was unwise. The Lancers chafing in the right gorge had thrice despatched their only subaltern as galloper to report on the progress of affairs. On the third occasion he returned, with a bullet-graze on his knee, swearing strange oaths in Hindoostani, and saying that all things were ready. So that Squadron swung round the right of the Highlanders with a wicked whistling of wind in the pennons of its lances, and fell upon the remnant just when, according to all the rules of war, it should have waited for the foe to show more signs of wavering. But it was a dainty charge, deftly delivered, and it ended by the Cavalry finding itself at the head of the pass by which the Afghans intended to retreat; and down the track that the lances had made streamed two companies of the Highlanders, which was never intended by the Brigadier. The new development was successful. It detached the enemy from his base as a sponge is torn from a rock, and left him ringed about with fire in that pitiless plain. And as a sponge is chased round the bath-tub by the hand of the bather, so were the Afghans chased till they broke into little detachments much more difficult to dispose of than large masses. "See!" quoth the Brigadier. "Everything has come as I arranged. We've cut their base, and now we'll bucket 'em to pieces." A direct hammering was all that the Brigadier had dared to hope for, considering the size of the force at his disposal; but men who stand or fall by the errors of their opponents may be forgiven for turning Chance into Design. The bucketing went forward merrily. The Afghan forces were upon the run--the run of wearied wolves who snarl and bite over their shoulders. The red lances dipped by twos and threes, and, with a shriek, up rose the lance-butt, like a spar on a stormy sea, as the trooper cantering forward cleared his point. The Lancers kept between their prey and the steep hills, for all who could were trying to escape from the valley of death. The Highlanders gave the fugitives two hundred yards' law, and then brought them down, gasping and choking ere they could reach the protection of the bowlders above. The Gurkhas followed suit; but the Fore and Aft were killing on their own account, for they had penned a mass of men between their bayonets and a wall of rock, and the flash of the rifles was lighting the wadded coats. "We cannot hold them, Captain Sahib!" panted a Ressaldar of Lancers. "Let us try the carbine. The lance is good, but it wastes time."
