Section 695(28) in Police Regulations, Bengal , 1943
(28)Should anyone approach the post or building between the hour of sunset and sunrise the sentry must challenge such person and order him to halt. Should he fail to get a satisfactory reply he will bring his musket to the 'ready' and take off the safety catch, at the same time calling out loudly for the guard to 'stand to'. Should the intruder still fail to obey the order to halt and persist in approaching the sentry's post, the sentry should again order him to halt and, at the same time, threaten to fire. Should the intruder still refuse to halt, the sentry may, at his discretion, use his bayonet or fire. Should there be more than one intruder and should they disobey the orders of the sentry and attempt to rush the building, he should not hesitate to open fire at once.
