Day after day the position of the besieged grew more unendurable. The buildings were crumbling away under the heavy and continued fire; and as one after another became absolutely untenable, the ladies and children were more closely crowded in those which still offered some sort of shelter. Even death, fearful as were its ravages, did not suffice to counteract the closeness of the packing. Crowded in dark rooms, living on the most meager food--for all the comforts, such as tea, sugar, wine, spirits, etc., were exhausted, and even the bread was made of flour ground, each for himself, between rough stones--without proper medicines, attendance, or even bedding; tormented by a plague of flies, sickened by disgusting smells, condemned to inaction and confinement, the women and children died off rapidly, and the men, although better off with regard to light and air, sickened fast. Half the officers were laid up with disease, and all were lowered in health and strength. On the 18th, as the Warreners had just returned from a heavy night's work, strengthening the defenses, and burying horses and cattle, a great explosion was heard, and one of those posted on the roof ran down shouting: "To arms! they have fired a mine under the Sikh Square!" Every man caught up his rifle and rushed to the spot. The mine had carried away a portion of the exterior defense, and the enemy, with yells of triumph, rushed forward toward the opening. Then ensued a furious _mêlée_; each man fought for himself, hand to hand, in the breach; Mussulmen and Englishmen struggled in deadly combat; the crack of the revolver, the thud of the clubbed guns, the clash of sword against steel, the British cheer and the native yell, were mingled in wild confusion. While some drove the enemy back, others brought boxes and beams, fascines and sandbags, to repair the breach. The enemy were forced back, and the British poured out with shouts of triumph. Our men's blood was up, and they followed their advantage. Part of the engineers, ever on the alert, joined the throng with some barrels of powder, and the enemy were pushed back sufficiently far to enable some of the houses, from which we had been greatly annoyed by the enemy's sharpshooters, to be blown up. This success cheered the besieged, and on the 20th, when it was discovered that the enemy were driving two new mines, a fresh sortie was determined upon.
