The Empire Trilogy - J. G. Farrell [310]
From the house a shallow trench had been dug out towards the crescent of earthworks behind which the cannons had been placed. Here, too, there was a pit about fourteen feet deep with a ladder against the side, down which the Collector now stiffly climbed. Lieutenant Cutter was standing at the bottom with his finger to his lips.
“Are they mining?”
“Yes. We’re digging a listening gallery.” Cutter described in a whisper what was happening: at the head of the gallery a man sat and worked with a short-handled pick or crowbar to loosen the earth; just behind him sat another man with an empty wine case to fill up with the loose earth; when full, this was drawn back by a rope.
The sepoys here were very close and it was thought inevitable that sooner or later they would begin mining, given the number of men at their disposal. For several nights the Collector had stayed up until dawn reading his military manuals by the light of an oil-lamp in his study to instruct himself in the art of military mining; only Cutter of the officers, two Cornish privates from Captainganj, and one or two Sikhs, had had any experience of mining before. What an advantage that knowledge can be stored in books! The knowledge lies there like hermetically sealed provisions waiting for the day when you may need a meal. Surely what the Collector was doing as he pored over his military manuals, was proving the superiority of the European way of doing things, of European culture itself. This was a culture so flexible that whatever he needed was there in a book at his elbow. An ordinary sort of man, he could, with the help of an oil-lamp, turn himself into a great military engineer, a bishop, an explorer or a General overnight, if the fancy took him. As the Collector pored over his manuals, from time to time rubbing his tired eyes, he knew that he was using science and progress to help him out of his difficulties and he was pleased. The inventions on his desk, the carriage which supplied its own track and the effervescent drinking vessel, watched him in silent admiration as he worked.
The Collector had learned that there are two cardinal rules of defensive mining...One is that your branch galleries (whose purpose is for listening to the approaching enemy miners) should run obliquely forward in order not to present their sides to the action of enemy mines ...The other is that the distance between the ends of the branch galleries should be such that the enemy cannot burrow between them unheard (a distance which varies with the nature of the soil but which can be roughly taken as twenty yards).
The trouble with these cardinal rules, though wonderful in their way, was that they required a great deal of digging. No doubt they would have served perfectly if there had been enough men in the garrison to dig listening galleries in the approved manner, reaching towards the enemy like the spread fingers of a hand. But Cutter lacked men. The best he and the Collector had been able to devise was a single lateral tunnel, slightly crescent-shaped to follow the contour of the ramparts, and which more resembled the hook of a man whose hand had been amputated.
The Collector, at the head of the gallery, strained his ears despondently for the scrape of the sepoy picks, but the only sound that came to them was the ghostly echo of a phrase of Vauban he had read: Place assiégée, place prise! For the Collector knew the truth of the matter: the sepoys did not even have to resort to mining. By using their artillery to make a breach in the defences and then digging a properly directed series of saps to approach it, they would be able to take the Residency in a matter of days. It was a commonplace of
