I finished my last letter to you the day before we left Candahar. Well; we started on Sunday, the 30th of June, and made seven marches to Belanti Ghiljee, where we caught up the Shah's army, with a Bengal division. Here Sir John Keane had first come in sight of young Dost's army, who, however, retired very quickly, though there was some talk of their holding out at this place, and we were pushed on rapidly in consequence. They shewed their sense in not holding out there, as it would not have taken us long to dislodge them. We halted here a day, and then marched on by very short and easy marches, halting every third or fourth day, and taking things very easy, although we were constantly annoyed by the Ghiljees, who murdered several of our camp followers, and tried to rob us whenever they could find an opportunity, until we were within five good marches of Ghuzni, when General Willshire received an order to push on by forced marches, and to make these five into three. After making two out of these three, (and precious long ones they were,) we found out that we were still upwards of twenty miles from Ghuzni, with the men so fatigued that it was nearly impossible for them to do it, and that we should therefore be obliged to make two of it. The event, however, proved the contrary; for, about seven o'clock in the evening, a dispatch came from General Willshire, and about eight, just as we were preparing to turn in, the orders were out to strike our tents, and march in an hour's time, and catch up Sir John Keane and the Shah, who were halted about nine miles in advance of us. Sir John was anxious to have the whole force concentrated before marching on Ghuzni. Nothing, however, was certain; and we were all in a high state of excitement, not knowing what to expect: this was the evening of the 20th. We made quick work of this march, and reached Sir John Keane about half-past twelve. Here we heard that Sir John Keane was in expectation of a night attack. He had fallen in that morning with the advance of the enemy, who had, however, upon the appearance of the British force, retired upon Ghuzni. We bivouacked on our ground, after throwing out strong pickets, and marched again at 5 A.M., Sir John Keane, the Bengalees, and cavalry in advance, then the Shah, and then our small party. We, however, sent our artillery to join Sir John. About eight o'clock, when within about three miles of Ghuzni, we heard the first symptoms that the game of war was beginning: our batteries were firing on the place, and the garrison were returning it with good effect; it served as a sort of overture to the opera in which we knew we must soon be actors.
