When the fort was first occupied, it was found that there was an exposed approach to the river from the water tower, about thirty yards in width; and a covered way was at once built, going right down into the water. All through the siege this covered way was the main object of the enemy's attack; for they knew that, if they could cut off the water, they could easily reduce the garrison.
An abutment in the south wall of the fort, overlooking the garden, had been converted into a little bastion. The worst feature of the fort, however, was the large number of little buildings immediately outside the walls. These and the walls of the garden were demolished by moonlight. The stables, which were on the river face near the water tower, were loopholed; and efforts were made to loophole the basement walls of the tower, but these had to be abandoned, as there was a danger of disturbing the foundations.
Among the various ingenious plans hit upon by the besieged, one proved particularly useful. Loopholes were made in the gun tower; a wall was built up in the face of the water gate; and fireplaces were constructed by which the wood, being laid on a slab of stone, was pushed out some feet from the wall, and could be drawn into the fort when it was necessary to replenish the fire, without those attending it being exposed. These fires proved invaluable, when attacks were made upon dark nights. Projecting, as they did, seven feet from the wall, they threw it into shadow, so that the enemy could not see what to fire at; and, at the same time, they lit up the ground in front brilliantly, so that the defenders could make out their assailants, and fire with accuracy.
The fort was eighty yards in length. The walls were twenty-five feet in height, and the five towers fifty feet. It lay in a hollow in the lowest part of the valley, and was commanded on all sides by hills, on which the enemy erected numerous sangars. As, from these, the men moving about inside the fort were clearly visible to the enemy, barricades of stones had to be erected, along the sides of the yards, to afford cover to the men as they went to and from their posts.
On March 5th a letter was received from Umra Khan, stating that the British troops must leave Chitral at once, and that he would guarantee them a safe conduct. The offer was, naturally, refused. Next night the enemy, about two hundred strong, made a determined effort to fire the water tower. They brought faggots with them and, in spite of the heavy volleys poured upon them managed, under cover of the darkness, to creep into the tunnel leading to the water, and to light a large fire underneath the tower. They were, however, driven out; and three water carriers went into the tunnel, and put out the fire. They were just in time, for the flames had taken a firm hold of the wooden beams.
After this, twenty-five men were always stationed in the tower and, at night, another picket of twenty-five men were placed in the covered way leading to the water. The entrance to this, at the water side, was exposed to the enemy's fire; but a barricade of stones, with interstices to allow the water to go through, was built into the river, and formed an efficient screen to the water bearers.
On the night of the 14th, the enemy again made an attack on the water bearers, but were repulsed with loss. The water way was, indeed, a source of constant anxiety. Between it, and the trees at the northwest corner of the fort, there was a stretch of seventy yards of sandy beach; lying underneath an overhanging bank, which entirely covered it from the fire of the fort, so that the enemy were able to get right up to the water tunnel without exposing themselves.
On the 15th, Sher Afzul sent in a messenger, to say that a party of sepoys had been defeated at Reshun, and that an officer was captive in his camp. The next day a letter was received from Lieutenant Edwardes. A truce was made for three days and, afterwards, extended to six; but this came to an end on the 23rd of March, and hostilities again began.
The prospect was gloomy. The men were beginning to suffer in health from their long confinement, the paucity of their rations, and the terribly insanitary condition of the fort; and they had not heard of the approach of either Colonel Kelly's force or that under Sir Robert Low.
During the truce, a union jack had been made, and this was now hoisted on the flag tower, as a symbol of defiance. This cheered the spirits of the men and depressed those of the enemy, who began to see that the task before them was far more serious than they had hitherto supposed.
