The sepoys at Barrackpore were bewildered and terrified. They were too afraid to speak, and began to set houses on fire. The suspicious telegraph office, the magic house at Barrackpore, was burnt down. Other buildings followed. The agitation was reported to the military authorities at Calcutta. The composition of the cartridge was explained to the sepoys. The drill was changed, and the sepoys were no longer required to bite the cartridge. But nothing would stop the panic. The sepoys argued with severe logic that if the cartridges had not been greased with the objectionable fat there would have been no occasion to change the drill. Eventually the issue of the greased cartridges was stopped altogether, but the sepoys were as suspicious as ever. As yet, however, there was no open mutiny at Barrackpore. Discipline was maintained with the usual strictness, and the word of command was obeyed without demur. Barrackpore was too near Calcutta, too near the stronghold of British supremacy which had controlled Bengal for a hundred years, for the sepoy as yet to dream of open mutiny. [Sidenote: Contagion at Berhampore.] §6. Matters were at this pass when a small guard of sepoys was sent on duty from Barrackpore to Berhampore, a hundred miles to the northward. Here, it will be remembered, was a regiment of sepoy infantry, half a regiment of sepoy cavalry, and a battery of sepoy artillery. The new arrivals from Barrackpore were duly feasted by their comrades of the sepoy infantry, and the whole story of the greased cartridges was told with all the latest embellishments of fiction. [Sidenote: Cartridges refused.] The next day, the 25th of February 1857, a parade for exercise with blank ammunition was ordered for the following morning. Blank cartridges were issued to the infantry of the same pattern that had been used for generations, but the sepoys refused to accept them. Colonel Mitchell was in command of the station, and threatened the men with court martial. Accordingly the sepoys took the cartridges in gloomy silence and returned to their lines. [Sidenote: Mutiny.] In the middle of the night the regiment rose as one man; it was the 19th Native Infantry of the Bengal army. Every company seized arms and ammunition from its magazine, and then the whole regiment rushed out of the lines and shouted defiance. Colonel Mitchell had no European force to suppress the outbreak; nothing but half a regiment of sepoy cavalry and the sepoy battery, and it was extremely doubtful whether the men would fire on the mutineers. However he ordered out the cavalry and battery, and advanced with his European officers towards the infantry lines by the light of torches. As he approached there was a halt and a pause. Tanks of water were in the way, and horses and guns might have been lost in the darkness. [Sidenote: Hesitation.]
