The warlike Hindu and Mahomedan races supplied excellent fighting material, when led by British officers, and the sepoy army took a distinguished part in every Indian battle, from Assaye to Gujarat.
During the Sepoy war of 1857-1858 the whole of the Bara Banki talukdars joined the mutineers, but offered no serious resistance after the capture of Lucknow.
British dash and sepoy fidelity, however, prevailed, first in the battle of Chengam (September 3rd, 1767), and again still more remarkably in that of Tiruvannamalai (Trinomalai).
In 1857 the sepoy garrison of the place initiated the mutiny of that year in Patna district, but after a conflict with the European troops were forced to retire from the town, and subsequently laid siege to Arrah.
Barrackpur played an important part in the two Sepoy mutinies of 1824 and 1857, but the details of these belong to the general history of British rule in India.
It had long been a fundamental principle of Indian government that the sepoy would always be true to his salt - knowing, as Macaulay wrote in 1840, that there was not another state in India which would not, in spite of the most solemn promises, leave him to die of hunger in a ditch as soon as he had ceased to be useful.
Lawrence saw that the surest way to prevent the Mutiny from spreading from the sepoy army of Bengal to the recently conquered fighting races of the Punjab was to hurl the Sikh at the Hindu; instead of taking measures for the defence of the Punjab, he acted on the old principle that the best defence is attack, and promptly organized a force for the reduction of Delhi, with the ardent co-operation of born leaders like John Nicholson, Neville Chamberlain and Herbert Edwardes.
