To-day (the 15th) has been one of almost absolute quiet. Beyond cavalry parties patrolling outside Sherpur, our men have not been sent out, although the Afghans crowded out upon the slopes above Deh-i-Afghan, inviting us to come out and attack them. There can be no good object attained, however, in again storming the heights, as we cannot weaken the garrison by telling off a couple of regiments and a mountain battery to hold the hills when captured. We had not, either, ammunition to throw away; there are only about 300 rounds per rifle of Snider and Martini-Henri, and we are as yet uncertain when reinforcements from Gundamak, bringing a further supply, will reach us. Luckily the telegraph remained open until five o’clock this morning, so full particulars of our condition were sent down the line. General Charles Gough has been ordered to bring in his brigade as quickly as possible; and he is now concentrating them at Jugdulluck. Colonel Hudson, commanding at Luttabund, has been ordered to hold on with the 300 Pioneers and the 28th Punjab Infantry, until General Gough reaches him. He will then come on to Sherpur. With the arrival of the brigade we shall be able, not merely to hold Sherpur in comfort, but also to send out 2,000 or 3,000 men to attack Mahomed Jan in whatever position he may take up. With more ammunition for our batteries, we can shell Deh-i-Afghan, the Bala Hissar, and even Cabul itself if occasion requires. At present we cannot afford to waste shells; as in the case of any check to General Gough’s brigade, we should have to rely upon our own strength until more troops could be sent forward from Jellalabad, and further down the Khyber line. We must make our calculations on this basis until we hear of the brigade from Jugdulluck being at Luttabund or Butkhak, which they should reach by the 19th or 20th at the latest. Asmatullah Khan, of Lughman, with his powerful section of Ghilzais, is reported to be anxious to join Mahomed Jan with 10,000 or 15,000 men, and he may try to intercept the force moving from Gundamak. As he would leave his villages west of the Darunta cliff at the mercy of a flying column from Jellalabad, he may, perhaps, hesitate before taking such a step. The Safis of Tagao, who returned to their homes yesterday afternoon, before our reverse, will soon learn that Cabul is still in the possession of Mahomed Jan, and they also may try to block the Luttabund Road.
