General Wilson at once followed up his success by sending out a column under Colonel Greathed to pursue the Sepoys who were making for Oudh. All went smoothly with this expedition, till Greathed had letters urgently begging him to turn aside for the relief of Agra, believed to be threatened by the advance of another army of mutineers from Central India. By forced marches the column made for Agra, where it arrived on the morning of October 10, and was received with great jubilation by the crowd pent up within the walls. But to the end it seemed as if the drama enacted on that gorgeous scene was destined to have tragi-comic features. The Agra people, under the mistaken idea that their enemies had fallen back, gave themselves to welcoming their friends, when mutual congratulations were rudely interrupted by the arrival, after all, of the Sepoys, who had almost got into the place without being observed. Sir George Campbell, so well-known both as an Indian official and as a member of Parliament, describes the scene of amazement and confusion that followed. He was at breakfast with a friend who had ventured to re-occupy his house beyond the walls, when a sound of firing was heard, at first taken for a salute, but soon suggesting something more serious. Sir George got out his horse, borrowed a revolver, and galloped down to the parade, on which he found round shot hopping about like cricket-balls. "It turned out that the enemy had completely surprised us. Instead of retreating, they had that morning marched straight down the metalled high-road--not merely a surprise party, but the whole force, bag and baggage, with all their material and many guns, including some exceedingly large ones; but no one took the least notice of them. There was a highly-organized Intelligence Department at Agra, who got unlimited news, true and false, but on this occasion no one brought any news at all. The only circumstance to favour the advance was that the high millet crops were on the ground, some of them ten or twelve feet high, and so the force marching down the road was not so visible as it would have been at another time. They reached the point where the road crossed the parade-ground quite unobserved. They probably had some scouts, and discovering our troops there, arranged themselves and got their guns in position before they announced themselves to us. The first attack was made by a few fanatics, who rushed in and cut down two or three of our men, but were not numerous enough to do material harm. If the enemy's real forces had made a rush in the same way, when no one expected them, there is no saying what might have happened; but, fortunately, as natives generally do, they believed in and stuck to their great guns, and instead of charging in, they opened that heavy fire which had disturbed us at breakfast."
