John James Hood Gordon, The Sikhs (1904)
“ It is said that no instance was known of a Sikh then captured consenting to abjure his religion. Death was the martyr's crown on such occasions. Henceforth the character of the Sikh resistance completely changed. To defend themselves against the Mahomedan invaders they formed organised confederacies of fighting men, each under one head chief. The necessity of fighting, how to resist, how to practise plunder, was the one law recognised. In 1748 Ahmad Shah, the Afghan king, aspired to found an Indian Empire, invaded the Punjab, and crossed the Sutlej after capturing Lahore. ”
