He had no choice left but to return to Mastuj immediately. So after remaining there only two hours he set out at 7 p.m. on the 17th on his return journey. A party had been previously despatched to seize the bridge over the river and the difficult piece of cliff along which the road passes, and the Punyali levies had been sent forward to if possible prevent the enemy from occupying the Nisa Gol position. These precautionary measures were successfully carried out; the enemy did nothing more than follow the party along the path, and Lieutenant Moberly after marching steadily all night halted for a few hours at dawn, and proceeded on to Mastuj, which he reached in safety about 10 a.m. on the 18th, having thus by a bold and carefully-planned march rescued Lieutenant Jones's party from probably the same fate that befell Lieutenant Edwardes's party. He did this, too, just in the nick of time, for only a few hours after he had left Buni, the enemy arrived there in force, and afterwards occupied the Nisa Gol position.
On the three days following his return to Mastuj, Lieutenant Moberly and Captain Bretherton were busily occupied in cutting down trees, from them making up fence-work round the fort, and completing defensive arrangements generally. The Hunza-Nagar levies, to the number of one hundred, were sent back to Ghizr on the other side of the Shandur to reinforce that post and be in communication with Gilgit. On the 25th news reached Mastuj that Lieutenants Fowler and Edwardes had been captured by the Chitralis. The enemy were now closing round the fort. A reconnaissance which Lieutenant Moberly had taken out on the 22nd showed that about six hundred of them were building and holding sangars at Chokalwat position, a few miles above Mastuj on the way to Gilgit, and a regular blockade of the fort now commenced.
Mastuj fort is about ninety yards square, and is built of masonry and woodwork, in the same manner as are all the forts in these parts. The walls are about twenty-five feet high, but at the time of the siege were in a dilapidated condition, for the place had only been temporarily occupied by the British as a residence for the political agent and his escort pending the decision of the Government as regards our permanent policy towards Chitral. And unfortunately a very severe earthquake in the previous year had shaken the walls very nearly to pieces. At that time I was the political agent there, and a little incident which occurred while the earthquake was taking place is worth recording as an instance of the steadiness of the native troops. Lieutenant Gurdon, the officer in command of the escort of Sikhs, and myself were seated in a room of the fort when we suddenly felt the whole place shaking. But earthquakes are common in Chitral and we did not at first move, till we heard stones crashing down outside and the whole room tossing about like a cabin on board ship. Then we dashed out of the door to the courtyard, and as we did so passed a sentry, who quietly proceeded to present arms in salute as if nothing was happening. The mountains round were in a cloud of dust from the avalanches of rock set rolling down their sides by the earthquake, and the rickety walls of the fort tumbling on all sides; but all this did not disturb the Sikh sentry; his sense of discipline was so ingrained that he saluted as usual, in the ordinary, everyday manner.
The Mastuj fort is situated on the edge of a sloping plain running down from the hill-side which at one point approaches to within about 400 yards of the fort. The enemy occupied a row of houses some 300 yards from the fort, which they loopholed, and from these commenced firing upon the fort. They also built sangars at a distance of 800 yards, but the garrison succeeded in silencing their fire by aiming volleys into them; and on one occasion Punyali levies were sent out at night to whitewash the loopholes of sangars out of which the enemy had been driven during the day, so that it would be possible for the garrison to aim correctly if the enemy attempted to reoccupy them. The enemy did subsequently come back to the sangars, but only to be driven out again by the carefully-aimed fire from the garrison.
On another occasion the Chitralis had built a sangar on the hill-side and from it wounded two ponies in the inside of the fort. The enemy were armed with Martini-Henry and Snider rifles and could fire from long ranges into the fort. It was necessary therefore to dislodge them from the sangar, and the Punyali levies were sent early one morning to destroy it before it had been occupied for the day by the enemy. Some days afterwards a sangar was built about 300 yards below the fort, but Lieutenant Moberly moved out with a party of eighty sepoys and rushed it. The enemy only fired a few shots, and then retired into some houses from which they harassed the return of the party. The sangar, which was found to be strongly built of fascines and stones, was destroyed.
All this time the Chitralis had been trying to induce Lieutenant Moberly to come out under the promise of a safe conduct to Gilgit, and he was assured that Sher Afzul, the pretender to the throne of Chitral, had no wish to fight the British. Had Lieutenant Moberly listened to these insinuating advances he would undoubtedly have been captured as soon as he came outside, and he acted wisely to wait for the relief which, though he was not aware of it, was now near at hand. On the 9th of April large numbers of the enemy were observed to be moving off, and Lieutenant Moberly took out his men to follow them up and harass them. Then it was that he met Colonel Kelly's force marching in to the relief of the garrison. The siege was now at an end; the tables were turned, and relieving and relieved forces now marched down to succour Chitral.
From the 10th to the 12th of April Colonel Kelly halted in Mastuj to allow of arrangements for supplies and transport for the further march to Chitral to be made, and to await the arrival of a second detachment of the troops catching up from the Shandur Pass. On the 11th of April this detachment arrived accompanied by Surgeon-Captain Luard with the Field Hospital, which was now established at Mastuj; and on the same day a reconnaissance was made by the levies in the direction of Chitral, as the enemy were reported to be holding a strong position a few miles below Mastuj. On the 12th of April a further reconnaissance was made by Lieutenant Beynon, the staff-officer, and an accurate sketch of the enemy's position brought back by him, which enabled Colonel Kelly to settle the course of his action. The position was generally considered to be impregnable, and the late Mehtar of Chitral had, standing on the very spot, himself explained to me its natural strength, and affirmed that it was one of the strongest positions in his country. In Chitral all the positions in the mountain valleys are well known and are regularly occupied in each successive invasion which occurs, and this position, Nisa Gol, is the one which has been selected from time immemorial by the Chitralis in the defence of their valley.
The valley of the Chitral River at the Nisa Gol position is about a mile wide, and is bounded on either hand by steep rocky mountains, rising for several thousand feet above the river. On the left bank especially the mountain sides are very precipitous, and up against these the Chitral River runs. On first looking down the valley it appears as if, in between the mountains, there was nothing but a smooth plain running down from the right-hand side, and it is not till one is actually on it that it is discovered that the seemingly open plain is cleft by a nullah between 200 and 300 feet deep, and with absolutely perpendicular sides. The nullah is the Nisa Gol, and only one path leads across it, that of the road to Chitral, and this path the enemy had now cut away. There had been a small goat-track across this nullah at another point, but the enemy had now entirely obliterated it. Sangars had also been erected at the head of these paths and along the right bank of the nullah. These sangars were sunk into the ground and head-cover was provided by a covering of timber and stones. On the left of their position they had sangars on the spur of the hill in a general line with the sangars on the plain, and on the hill parties of men were stationed to throw down stones. On the right of their position across the Chitral River, and slightly in advance of the general line, they had another line of sangars on a spur stretching away high up into the snow-line.
Such was the position which Colonel Kelly had now to attack, and in it the Chitralis had collected to the number of about 1,500 men under their chief leader, Mohamed Isa, to make their principal stand, so as to prevent Colonel Kelly joining hands with the British garrison in Chitral.
