The intention of the conspirators was not only to kill the Englishman, but to dethrone the rajah, and install his brother in his place. The attack had commenced with the attempt upon Charlie's life, because it was believed that his death would paralyse the troops who were faithful to the rajah. At the end of six weeks, Charlie was able to resume his duties, and his appearance at the parade ground was hailed with enthusiastic shouts by the soldiers. The rajah was more attached to him than ever, and had again made him large presents, in token of the regret he felt at the sufferings he had endured in his cause. Drilling was now carried on with redoubled energy, and large numbers of new levies had been summoned to the standard. A storm was gathering over Ambur. The rajah's brother was raising a force to attack him, and had, by means of large promises in case of success, persuaded Murari Reo to take up his cause; and he had, it was said, also sent messages to the nizam, pointing out that, in case of war with the English, the Rajah of Ambur would be a thorn in his side. He told of the numbers of troops who had been drilled, and how formidable such a force would be, if opposed to him at a critical moment; while if he, the claimant, gained power, the army of Ambur would be at the disposal of the nizam. The rajah, on his side, had also sent messengers to Hyderabad, with assurances to the nizam of his fidelity and friendship. He urged that the preparations he had made were intended solely for the defence of his state, against marauding bands of Mahrattas, and especially against those of Murari Reo, who was a scourge to all his neighbours. In the meantime, every effort was made to strengthen the defences of Ambur. The walls surrounding the town were repaired, and although these, in themselves, could have offered but a slight defence to a determined assault, the approaches to the town were all covered by the guns of the fort above. The weak point of the defence was the hill behind the town. This sloped up, gradually, to a point higher than the level of the projecting rock upon which the castle stood. It then rose, in rugged cliffs, some two hundred feet higher; and then fell away again, steeply, to its summit. This was too far back for the fire of guns placed upon it to injure the castle or town. Guns placed, however, at the foot of the rocky wall, would dominate the castle and render it, at last, untenable. Charlie had often looked, with an anxious eye, at this point; and one morning, accompanied by the rajah, he rode up to examine the position. The highest point of the slope, at the foot of the crag, was nearly opposite the castle; and it was here that an active enemy, making his way along the slope, would place his guns. Here, Charlie determined to establish a battery.
