The crime was avenged by Robert Clive, the English commander at Madras. With only 100 English soldiers and 2000 sepoys (native soldiers in European employ), he sailed for Calcutta, recaptured that place, and on the memorable field of Plassey, scattered to the winds the Nabob's army of 60,000 (1757).

During the first half of the present century the opium traffic between India and China grew into gigantic proportions, and be-
