Then they strolled back to the Residency, where Kavanagh told the story of the relief; of the capture of the various rebel positions; the meeting of General Campbell with Generals Havelock and Outram; of the retirement in the night, the march to Cawnpore, the terrible revenge of the British troops on the rebels, and the return of the army in the following spring. And then, with a hearty hand-shake and farewell, he said good-bye, mounted his horse, which a native groom was holding close by, and galloped off toward the city. This was the man who ventured through the closely-drawn lines of 50,000 rebel sepoys, where discovery would have been certain death, and most probably death by torture. CHAPTER XXXI. LUCKNOW TO CAWNPORE AND AGRA.--TAJ MAHAL AND FUTTEHPOOR SIKRA. From Lucknow to Cawnpore our friends had a ride of a little over two hours, through a fertile country, which was quite flat and uninteresting--a repetition of the journey from Benares to Lucknow. Cawnpore stands on a level plain, on the right bank of the Ganges, and covers a large area of ground; it would be almost without interest were it not for the terrible atrocities of Nena Sahib and his followers during the Mutiny. A sad prominence was given to Cawnpore in 1857, so that few travellers will care to pass it without looking at the memorials of the events which at one time agitated the whole civilized world. [Illustration: LOW-CASTE INHABITANTS OF CAWNPORE.] A couple of hours will suffice for seeing the points of interest, and it happened that the train for the north gave the Doctor and his young companions all the time they needed for the excursion. They engaged a carriage and started at once, and as they rode along the Doctor told in brief the story of Cawnpore. Nena Sahib was a native prince of enormous wealth; a few years before the Mutiny he had a lawsuit with the East India Company, which was decided against him, and from that time he had the most bitter hatred for the English, though he associated freely with them, and professed the warmest friendship. He entertained them often at his palace, which was filled with European furniture and pictures, and when the rebellion broke out no one supposed he had favored it or would take any part in the hostilities.
