The news reached Sir Henry Lawrence in the evening, and he resolved to act at once. He crossed the river and called out the European forces and the four regiments of regular sepoys, and then advanced against the mutineers, whose lines were seven miles off. The rebels were taken by surprise; they could do nothing. They were ordered to form in front of their lines, and they obeyed. They saw cavalry and infantry, soldiers and sepoys, on either side, and a battery of eight guns in front. They were ordered to lay down their arms, and they did so. The port-fires of the artillery were lighted. The mutineers were seized with a panic, and cried out, "Do not fire!" They then rushed madly away. The ringleaders and most of their followers were arrested that night by the Bengal sepoys, and were confined pending trial. It will be seen hereafter that within a single month, the very sepoy regiments that arrested the mutinous irregulars rose against their European officers. Meanwhile, however, the quick action of Sir Henry Lawrence prevented any premature explosion, and gave him the month to prepare against the possible contingency. [Sidenote: Disbandment of 34th Native infantry.] Next day the outbreak and suppression of the mutiny were telegraphed to Lord Canning at Calcutta. He was delighted with the promptitude and prudence of Sir Henry Lawrence. He saw the necessity for taking some decided action at Barrackpore. The European officers of the 34th Native Infantry reported that the sepoys were disaffected, and that they themselves had lost all confidence in the men. Accordingly Lord Canning determined to disband the regiment. On the 6th of May, at early morning, the Europeans were once again drawn up on the parade ground. The 34th Native Infantry was disbanded as the 19th had been five weeks before, but, unlike the sepoys of the 19th, they showed no signs of contrition. Still, it was hoped that the disbandment of the 34th would put an end to the mutiny. [Sidenote: Sepoys and Europeans at Meerut.] §9. So far the agitation was the work of the greased cartridges in Dumdum arsenal. But there was a second school of musketry at Meerut in the North-West Provinces, a thousand miles from Calcutta and only forty miles from Delhi. The military cantonment at Meerut covered an area of five miles, and was the largest in India. At one end were the lines of three sepoy regiments, two of infantry and one of cavalry, whilst the bungalows of the European officers were scattered about. At the other end of the cantonment were the European barracks, in which a European force was quartered strong enough to have routed four times the number of sepoys. There was a regiment of Dragoon Guards, known as the Carabineers; a battalion of the 60th Rifles; two troops of horse artillery, and a light field battery. The European barracks were thus at a long distance from the sepoy cantonments, and the interval was occupied by shops, houses, and gardens. [Sidenote: Disaffection.]
