The reinforcements had arrived but just in time, for Captain Knox, who commanded at this post, and nearly half his force, had fallen before Major Warrener's band had come up to their aid. The next day, and the next, and the next, the sorties from the city were repeated, with ever-increasing force and fury, each fresh body of mutineers who came into the city being required to testify their loyalty to the emperor by heading the attack on his foes. Desperately the little British force had to fight to maintain their position, and their losses were so serious, the number of their enemies so large, so rapidly increasing, that it was clear to all that the most prodigious efforts would be necessary to enable them to hold on until reinforcements arrived, and that all idea of an early capture of the city must be abandoned.

Warrener's Horse, however, had no share in these struggles, for on the day after the fight at the flagstaff a report spread among them that they were again to start upon an expedition. A note had been brought in by a native to the effect that several English ladies and gentlemen were prisoners at the fortress of Bithri, in Oude, some hundred and fifty miles from Delhi. The instructions given to Major Warrener were that he was to obtain their release by fair means, if possible; if not, to carry the place and release them, if it appeared practicable to do so with his small force; that he was then to press on to Cawnpore. Communications had ceased with Sir H. Wheeler, the officer in command there; but it was not known whether he was actually besieged, or whether it was merely a severance of the telegraph wire. If he could join Sir H. Wheeler he was to do so; if not, he was to make his way on, to form part of the force which General Havelock was collecting at Allahabad for an advance to Cawnpore and Lucknow. It would be a long and perilous march, but the troops were admirably mounted; and as they would have the choice of routes open to them, and would travel fast, it was thought that they might hope to get through in safety, and their aid would be valuable either to Sir H. Wheeler or to General Havelock.

It was a lovely moonlight evening when they started. During their stay at Delhi they had, profiting by their previous expedition, got rid of every article of accouterment that could make a noise. Wooden scabbards had taken the place of steel, and these were covered in flannel, to prevent rattle should they strike against a stirrup. The water bottles were similarly cased in flannel, and the rings and chains of the bits in leather. Nothing, save the sound of the horses' hoofs, was to be heard as they marched, and even these were muffled by the deep dust that lay on the road. Each man, moreover, carried four leathern shoes for his horse, with lacings for fastening them. Under the guidance of two natives, the troop made their first six stages without the slightest adventure. The country was flat, and the villages sparsely scattered. The barking of the dogs brought a few villagers to their doors, but in those troubled times the advantages of non-interference were obvious and the peasant population in general asked nothing better than to be let alone.

The troop always marched by night, and rested by day at villages at a short distance from the main road. Upon a long march like that before them, it would have been impossible to maintain secrecy by resting in woods. Food for men and horses was requisite, and this could only be obtained in villages. So far no difficulty had been met with. The head men of the villages willingly provided provender for the horses, while flour, milk, eggs, and fowls were forthcoming in sufficient quantities for the men, everything being strictly paid for.

The last night march was as successful as the preceding, and crossing the river by a bridge at Banat, they halted some five miles from the fortified house, or castle, which was the immediate object of their expedition. They were now in Oude, and had, since crossing the river, avoided the villages as much as possible, for in this province these are little fortresses. Each is strongly walled and guarded, and petty wars and feuds are common occurrences. The people are warlike, and used to arms, and without artillery even a small village could not be carried without considerable loss. The troops therefore had made circuits round the villages, and bivouacked at the end of their march in a wood, having brought with them a supply of food and grain from the village where they had halted on the previous day. They had not slept many hours when one of the vedettes came in to say that there was a sound of beating of drums in a large village not far away, and that bodies of peasantry had arrived from other villages, and that he believed an attack was about to take place.

Major Warrener at once took his measures for defense. The first troop were to defend the front of their position with their carbines against an attack. The second troop were to move round to the extreme end of the tope, were to mount there, and when the enemy began to waver before the musketry fire, were to sweep round and take them in flank. Major Warrener himself took command of the dismounted troop, and posted the men along behind a bank with a hedge, a short distance in front of the trees. Then, each man knowing his place, they fell back out of the scorching sunshine to the shade of the tree's, and waited. In half an hour a loud drumming was heard, and a motley body, two or three thousand strong, of peasants in a confused mass, with a tattered banner or two, made their appearance.

The "Avengers," as Warrener's Horse called themselves, took their places behind the bank, and quietly awaited the attack. The enemy opened a heavy fire, yet at a long distance. "Answer with a shot or two, occasionally," Major Warrener had ordered, "as they will then aim at the bank instead of tiring into the wood. We don't want the horses hurt."

Slowly and steadily the rifled carbines spoke out in answer to the heavy fire opened on the bank, and as almost every man of Warrener's Horse was a sportsman and a good shot, very few shots were thrown away. The enemy beat their drums more and more loudly, and shouted vociferously as they advanced. When they were within three hundred yards Major Warrener gave the word:

"Fire fast, but don't throw away a shot."

Astonished at the accuracy and deadliness of the fire which was poured into them by their still invisible foe, the enemy wavered. Their leaders, shouting loudly, and exposing themselves bravely in front, called them on, as slowly, and with heavy loss, the main body arrived within a hundred yards of the hedge. Those in front were, however, falling so fast that no efforts of their leaders could get them to advance further, and already a retrograde movement had begun, when there was a yell of fear, as the mounted troop, hitherto unnoticed, charged furiously down upon their flank.
