Read it through once

The Black Hole was not preserved; it is gone, long, long ago. It is strange. Just as it stood, it was itself a monument; a ready-made one. It was finished, it was complete, its materials were strong and lasting, it needed no furbishing up, no repairs; it merely needed to be let alone. It was the first brick, the Foundation Stone, upon which was reared a mighty Empire—the Indian Empire of Great Britain. It was the ghastly episode of the Black Hole that maddened the British and brought Clive, that young military marvel, raging up from Madras; it was the seed from which sprung Plassey; and it was that extraordinary battle, whose like had not been seen in the earth since Agincourt, that laid deep and strong the foundations of England's colossal Indian sovereignty.
