On August 10, the Sepoys delivered another assault, but were more easily beaten off this time. It began by the explosion of a mine, which threw down the front of the Martinière post, ruining also some fifty feet of palisading and other bulwarks on each side. The assailants wanted boldness to master the breach thus made; but they lodged themselves in an underground room of this house, from which they had to be expelled by hand-grenades, dropped among them through a hole in the floor, and they got no further within the quickly-restored defences. At first, it is said, they could have walked in through an open door, which Mr. Schilling and his boys had the credit of shutting in their faces. The School would all have been blown up, but for the good fortune of having just been called in to prayers in an inner room. Three soldiers had been hurled by the explosion on to the enemy's ground, but ran back into the entrenchment, unhurt, under a shower of bullets. The Sepoys' fire was kept up as hotly as ever, though at times they seemed to be badly off for shot, sending in such strange projectiles as logs of wood bound with iron, stones hollowed out for shells, twisted telegraph wires, copper coins and bullocks' horns; even the occasional use of bows and arrows lent a mediæval feature to the siege. Their main effort now seemed directed to the destruction of the walls by mining. Here they were foiled, chiefly through the vigilance of Captain Fulton, an engineer-officer, who took a leading part in the defence, only to die before its end, like so many others. In the ranks of the 32nd, he found a number of old Cornish miners, with whose help he diligently countermined the subterranean attacks. Now the burrowing Sepoy broke through into an unsuspected aperture, to find Fulton patiently awaiting him, pistol in hand. Again, a deep-sunk gallery from within would be pushed so far, that our men blew up not only the enemy's mine, but a house full of his soldiers. The garrison had always their ears strained to catch those muffled blows, which announced new perils approaching them underground; then, as soon as the situation and direction of the mine could be recognized, Fulton went to work and the dusky pioneers either gave up the attempt or came on to their doom.
