Suddenly on May 3d there was an explosion at Lucknow. A regiment of Oudh Irregular Infantry, previously in the service of the Mogul, broke out in mutiny and began to threaten their European officers. Sir Henry Lawrence, the new Chief Commissioner, had a European regiment at his disposal, namely the Thirty-second Foot. That same evening he ordered out the regiment, and a battery of eight guns manned by Europeans, together with four sepoy regiments, three of infantry and one of cavalry. With this force he proceeded to the lines of the mutineers, about seven miles off. The Oudh Irregulars were taken by surprise; they saw infantry and cavalry on either side, and the European guns in front. They were ordered to lay down their arms, and they obeyed. At this moment the artillery lighted their port fires. The mutineers were seized with a panic, and rushed away in the darkness; but the leaders and most of their followers were pursued and arrested by the native infantry and cavalry, and confined pending trial. Subsequently it transpired that the native regiments sympathized with the mutineers, and would have shown it but for their dread of Sir Henry Lawrence and the Europeans. The energetic action of Lawrence sufficed to maintain order for another month in Oudh. Meanwhile the Thirty-fourth Native Infantry was disbanded at Barrackpur, and again it was hoped that the disaffection was stayed. The demon of mutiny was only scotched. Within a week of the outbreak at Lucknow, the great military station of Meerut was in a blaze. Meerut was only forty miles from Delhi, and the largest cantonment in India. There were three regiments of sepoys, two of infantry and one of cavalry; but there were enough Europeans to scatter four times the number; namely, a battalion of the Sixtieth Rifles, a regiment of Dragoon Guards known as the "Carabineers," two troops of horse-artillery, and a light field-battery. In spite of the presence of Europeans there were more indications of excitement at Meerut than at any other station in the northwest. At Meerut the story of the greased cartridges had been capped by the story of the bonedust; and there were the same kind of incendiary fires, the same lack of respect toward European officers, and the same whispered resolve not to touch the cartridges, as at Barrackpur. The station was commanded by General Hewitt, whose advancing years unfitted him to cope with the storm which was bursting upon Hindustan. The regiment of sepoy cavalry at Meerut was strongly suspected of disaffection; accordingly it was resolved to put the men to the test. On May 6th it was paraded in the presence of the European force, and cartridges were served out; not the greased abominations from Calcutta, but the old ones which had been used times innumerable by the sepoys and their fathers.
