The next day the insurgents made a third attack, and were again repulsed with considerable loss. They knew that Hindu Rao's house was the key of our position, and throughout the siege they made the most desperate attempts to capture it. But Barnard had entrusted this post of danger to the Gurkhas, and all efforts to dislodge them were unavailing. At first Reid had at his command only his own battalion and two companies of the 60th Rifles; but on the arrival of the Guides their Infantry were also placed at his disposal, and whenever he sounded the alarm he was reinforced by two more companies of the 60th. Hindu Rao's house was within easy range of nearly all the enemy's heavy guns, and was riddled through and through with shot and shell. Reid never quitted the Ridge save to attack the enemy, and never once visited the camp until carried into it severely wounded on the day of the final assault. Hindu Rao's house was the little Gurkhas' hospital as well as their barrack, for their sick and wounded begged to be left with their comrades instead of being taken to [camp].[14]

Failing in their attempts on the centre of the position, the mutineers soon after daylight on the 12th, having concealed themselves in the ravines adjoining Metcalfe House, attacked the Flagstaff Tower, the piquet of which was composed of two Horse Artillery guns and two companies of the 75th Foot, under the command of Captains Dunbar and Knox. A heavy fog and thick mist rolling up from the low ground near the Jumna completely enveloped the Ridge and the left front of our position, hiding everything in the immediate vicinity. The piquet was on the point of being relieved by a detachment of the 2nd Bengal Fusiliers, when a large body of the enemy, who had crept up unobserved, made a rush at the Flagstaff Tower, and as nearly as possible captured the guns. The piquet was hardly pressed, Knox and several men were killed, and but for the timely arrival of two companies of the 60th, the rebels would have gained the day.

This engagement was scarcely over, when masses of insurgents advanced from the Sabzi Mandi upon Hindu Rao's house, and into the gardens on the right flank of the camp, threatening the Mound piquet. Reserves were called up, these attacks, in their turn, were repulsed and the rebels were pursued for some distance. It was most fortunate that both attacks did not take place simultaneously, as was the obvious intention of the enemy, for our strength would not have been sufficient to repel them both at the same moment.

In order to prevent the mutineers from coming to such close quarters again, a piquet was placed in Metcalfe's House, and the Mound to the rear of the ridge facing the Sabzi Mandi was strengthened. These precautions ought to, and would, have been taken before, but for the want of men. Our soldiers were scarcely ever off duty, and this fresh demand made it impossible at times to provide a daily relief for the several piquets.

Our resources in siege guns and ammunition were so limited, daily sorties, disease, and heat were making such ravages amongst our small force, there was so little hope of receiving any considerable reinforcements, and it appeared to be of such paramount importance to capture Delhi without further delay, that Barnard agreed to a proposal for taking it by a coup de main.

Proposed Assault The particular details of the project and disposition of the troops were worked out by three young officers of Engineers, under the direct orders of the General, and were kept a profound secret; even the Commanding Engineer was not made acquainted with them. Secrecy was, of course, of vital importance, but that the officers who ought to have been chiefly concerned were kept in ignorance of the scheme, shows there was little of that confidence so essential to success existing between the Commander and those who were in the position of his principal advisers. Practically the whole force was to be engaged, divided into three columns—one to enter by the Kashmir gate, the second by the Lahore gate, and the third was to attempt an escalade. The three columns, if they succeeded in effecting an entrance, were to work their way to the centre of the city, and there unite.

It was intended that these columns should move off from camp so as to arrive at the walls just before daybreak; accordingly, at one o'clock on the morning of the 13th June the troops were suddenly paraded and ammunition served out, and then for the first time the Commanders of the three columns and the staff were made acquainted with the General's intentions. It so happened that the 75th Foot, which had followed the enemy into the grounds of Metcalfe House after the repulse on the Flagstaff Tower the previous morning, had through some oversight never been recalled; their absence was only discovered when the order was given for the regiment to turn out, and a considerable time was wasted in sending for it and bringing it back to camp. Day was breaking when this regiment received its ammunition, and all hope of an unperceived advance to the walls had to be given up. The troops were therefore dismissed, and allowed to turn in, having been uselessly disturbed from their much-needed rest.

The failure to give effect to the young Engineer officers' plan may be looked upon as a merciful dispensation of Providence, which saved us from what would almost certainly have been an irreparable disaster. When we think of the hard fighting encountered when the assault did take place under much more favourable circumstances, and how the columns at the end of that day were only just able to get inside the city, those who had practical knowledge of the siege can judge what chance there would have been of these smaller columns accomplishing their object, even if they had been able to take the enemy by surprise.

The 13th and 14th passed in comparative quiet; but early on the 15th a strong force advanced from Delhi against the Metcalfe House piquet, with the object of turning our left flank, but it was driven back with considerable loss.

Hard Fighting On the 17th we were attacked from almost every direction—a manœuvre intended to prevent our observing a battery which was being constructed close to an [Idgah],[15] situated on a hill to our right, from which to enfilade our position on the Ridge. As it was very important to prevent the completion of this battery, Barnard ordered it to be attacked by two small columns, one commanded by Tombs, of the Bengal Horse Artillery, the other by Reid. Tombs, with 400 of the 60th Rifles and 1st Bengal Fusiliers, 30 of the Guides Cavalry, 20 Sappers and Miners, and his own troop of Horse Artillery, moved towards the enemy's left, while Reid, with four companies of the 60th and some of his own Gurkhas, advanced through Kishenganj against their right. Tombs drove the rebels through a succession of gardens till they reached the Idgah, where they made an obstinate but unavailing resistance. The gates of the mosque were blown open, and thirty-nine of its defenders were killed. Tombs himself was slightly wounded, and had two horses killed, making five which had been shot under this gallant soldier since the commencement of the campaign. Reid's attack was equally successful. He completely destroyed the battery, and inflicted heavy loss on the enemy.
